Arkana review — PR #1083: token rails from LNURL
No protocol-critical paths touched (no VTXO, signing, forfeit, round, or exit changes). Cross-repo check: receiveViaTokens, LnurlTokenRail, and LnurlTokenQuote are wallet-local; no SDK consumers found.
Findings
1. o.verifiable !== false admits options with verifiable: undefined
src/lib/receive/lnurlTokenRails.ts line ~420
const offered = o.available && o.verifiable !== false && o.unit.decimals <= 18 && inBoundsIf the lnurl-client ever returns an option where verifiable is absent/undefined, the condition passes. The test suite only exercises verifiable: false being excluded. If the intent is "must be explicitly verifiable", tighten to o.verifiable === true. Low risk given the current server contract, but worth an explicit assertion here.
2. plausibleQuote only guards USDT/USDC
src/lib/receive/lnurlTokenRails.ts line ~406
if (!['USDT', 'USDC'].includes(unit) || !(requestedUsd > 0)) return trueEURC, DAI, PYUSD, and any future USD-pegged token are returned as true (no opinion). The test covers this as a deliberate choice. That's fine for now, but as the provider catalogue widens the misquote guard will silently not apply. A follow-up issue or a comment naming the known-uncovered tickers would be useful.
3. EIP-681 URI extra query parameters pass paysQuote unexamined
src/lib/receive/lnurlTokenRails.ts lines ~355–372
paysQuote validates address and uint256, but does not reject additional parameters (e.g. memo, gas, data). A server returning ethereum:TOKEN@CHAIN/transfer?address=DEST&uint256=AMOUNT&memo=EXTRA would pass and the full URI would appear in the QR and in the "Open in wallet" link.
The security boundary that matters—that the receiver and amount are correctly bound—is intact. The copy path correctly uses destination, not the URI (src/screens/Wallet/Receive/QrCode.tsx line ~697). This is informational: extra parameters can't redirect funds, but they could carry tracking data or confuse some wallet parsers. Worth noting if the server ever misbehaves.
4. Copy button enabled but silent in the token-error state
src/screens/Wallet/Receive/QrCode.tsx line ~837
<Button label={t('receive.copy')} onClick={handleCopyButton} secondary disabled={generating} />When a token option is active, generating = tokenRails.quoting. After a quote failure (quoting: false, quote: undefined, error: "…"), generating is false and the button is enabled, but handleCopyButton computes value = tokenQuote?.destination ?? qrCodeValue → undefined ?? '' → '', so nothing is copied and no sheet appears. The user clicks Copy and nothing happens.
Consider disabled={generating || (activeToken && !tokenQuote)} to disable the button when there is an active token with no usable quote.
5. Big PR
Danger already flagged 1545 changed lines. The split series described in the PR body (six independent PRs) shows this has already been decomposed; this is the last large chunk. No further split is practical here.
What looks correct
paysQuote: thejavascript:alert(1)test confirms the non-ethereum:/solana:scheme rejection path; all URI-to-address fallback branches are tested.wholeTokens: correctly rejects'0','007','1e7', and decimal-notation strings; only plain positive integers accepted.- Quote freshness: the
askedrecord (lnurl + optionId + amountSat + round) eliminates stale quotes across receiver swaps, amount changes, option changes, and expiry re-requests. Tests cover all four axes, including the "old-option still in flight while user picks original again" case. MAX_TIMEOUT_MS = 2 ** 31 - 1correctly capssetTimeoutto avoid a 32-bit overflow wrapping to an immediate fire.setAnswer(undefined)on effect cleanup ensures expired or superseded quotes are never surfaced.- Copy sheet scoped to the active method: token methods show address + amount only, never the BIP21 URI, and the URI is never written to the clipboard.
receiveViaTokensdefaults tofalse; feature is dark until #1084.mapKnownErrorsmillisats→sats conversion usesMath.ceilfor min andMath.floorfor max (correct rounding for an exclusive-range error message).- No cross-repo type or API surface changes.

Catchup pass — 7 commits since c13c291. Prior findings: 2 fixed, 2 still open (informational, no change). No new blocking issues.
Prior findings — close-out
1. o.verifiable !== false admits verifiable: undefined — Fixed (8fab7d5)
src/lib/receive/lnurlTokenRails.ts: changed to o.verifiable === true. Test case ['no verifiable flag', { verifiable: undefined }] added in lnurlTokenRails.test.ts.
2. plausibleQuote only guards USDT/USDC — Still open, no change
No code touched this path in the incremental diff. Still informational: EURC, DAI, PYUSD and any future USD-pegged option get true with no opinion. The existing comment acknowledging this is sufficient for now; suggest a follow-up issue before the provider catalogue widens.
3. EIP-681 extra query parameters pass paysQuote unexamined — Still open, no change
paysQuote in lnurlTokenRails.ts is unchanged. Still informational: extra parameters cannot redirect funds or change the amount, but could carry tracking data or confuse some wallet parsers. No immediate action needed.
4. Copy button enabled but silent in token-error state — Fixed (8fab7d5)
src/screens/Wallet/Receive/QrCode.tsx line ~588: disabled={generating || Boolean(activeToken && !tokenQuote)}. Integration assertion added in receive-lnurl.test.tsx: expect(screen.getByRole('button', { name: 'Copy' })).toBeDisabled().
Incremental-diff observations
IndexedDB connection leak on error — fixed (9fdd8d38ed69)
src/lib/lnurlPaymentRepository.ts: three error-path handlers were missing db.close() before rejecting. All three paths now close the connection. Clean fix; a leaked IDB handle can block subsequent open() calls on the same store.
Race condition: LNURL legs requested before own addresses loaded — fixed (6b143b41ea17)
src/lib/receive/lnurlRail.ts: arkade and onchain legs are now gated on ownArkade / ownOnchain being truthy before they're added to the request set. Test in useLnurlRail.test.ts correctly exercises the before/after states. One thing to note: when addresses arrive after the first effect run, the hook re-fires and re-requests all three rails from scratch (including lightning). That's correct behaviour — the stale-flag cancel handles the earlier in-flight request — but it means the lightning leg is fetched twice on the common path where addresses load asynchronously. Functionally harmless (the first response is dropped), and the server-side cost is negligible, but worth noting if the LNURL server ever rate-limits per-request.
lnurlLabel i18n refactor — clean (9fdd8d38ed69)
src/lib/swapDisplay.ts: lnurlLabel now takes t as a parameter rather than hardcoding English strings. All call sites and tests updated consistently. Language test added covering Spanish output. No issues.
New swapRail.test.tsx (9965cdda968e)
Covers the useSwapRail(enabled = false) path that was previously untested. The "negotiates nothing while disabled" test correctly checks sync state after render without awaiting. No issues.
LnurlRail.tsx i18n (9fdd8d38ed69)
All previously hardcoded English strings replaced with t(...) keys that are present in both en and es translation blocks. No issues.
Summary
The two actionable findings from the prior pass are fixed. The two informational notes are unchanged and remain lower-priority follow-ups. The incremental commits fix real bugs (IDB leak, address-race) and add coverage. No protocol-critical paths are touched.

4 commits since last pass (stale-invoice fix, i18n claim errors, activity dedup, layoutEffect ref). 2 of 4 prior findings remain open (informational). 1 new finding: Share button is still unguarded in the token-error state.
Prior findings — close-out
1. o.verifiable !== false admits verifiable: undefined — Fixed (8fab7d5, confirmed prior pass)
2. plausibleQuote only guards USDT/USDC — Still open, no change
No code touching this path in the incremental diff. Still informational: EURC, DAI, PYUSD get true with no opinion. Unchanged from prior pass.
3. EIP-681 extra query parameters pass paysQuote unexamined — Still open, no change
paysQuote in lnurlTokenRails.ts is unchanged. Still informational; cannot redirect funds. Unchanged from prior pass.
4. Copy button enabled but silent in token-error state — Fixed (8fab7d5, confirmed prior pass)
disabled={generating || Boolean(activeToken && !tokenQuote)} at line 593. Verified.
Incremental-diff observations
5. activityHistory.ts — [].every() vacuous-truth fix is correct
src/lib/activityHistory.ts line 277: adding activity.txs.length > 0 before every() correctly prevents an empty sent: group (which produces no rows regardless) from being silently skipped. The txid is also hoisted out of the loop. Clean.
6. lnurlRail.ts — layout-effect ref fix is correct
src/lib/receive/lnurlRail.ts lines 224–226: moving current.current = facade from render into useLayoutEffect is the correct fix. Assigning a ref during render is a side effect that strict-mode can execute on an abandoned render; useLayoutEffect only fires on commit. This closes the race described in the commit message without any API-surface change.
7. QrCode.tsx — stale swap invoice fix is correct and tested
src/screens/Wallet/Receive/QrCode.tsx line 155:
const invoice = (swapRailOn ? recvInfo.invoice : undefined) || lnurlRails.targets.lightning || ''When the LNURL rail is serving Lightning (swapRailOn = false), a swap invoice persisted from a prior navigation is now suppressed. The new test at receive-lnurl.test.tsx line 219 exercises this path directly. Clean.
8. Share button not guarded in token-error state — NEW, actionable
src/screens/Wallet/Receive/QrCode.tsx line 410:
const shareDisabled = !canBrowserShareData(data) || sharing || hasError || noPaymentMethods || generatingdata = { title: t('wallet.receive'), text: qrCodeValue }. When an active token has an error (no quote): qrCodeValue is '' (the token method's value is empty until a quote exists), and generating is false. canBrowserShareData delegates to navigator.canShare, which returns true when title is non-empty regardless of text — so the button is enabled. Clicking Share fires navigator.share({ title: 'Receive', text: '' }), presenting a share dialog with no payment content.
The Copy button received the analogous fix in 8fab7d5 (disabled={generating || Boolean(activeToken && !tokenQuote)}). Share needs the same guard:
const shareDisabled =
!canBrowserShareData(data) || sharing || hasError || noPaymentMethods || generating ||
Boolean(activeToken && !tokenQuote)CodeRabbit raised this in their prior pass as an inline comment on this exact location; it was not addressed by the subsequent commit.
Summary
The stale-invoice bug, layoutEffect ref race, i18n claim errors, and activity-dedup edge case are all clean fixes. The one remaining actionable item is the Share guard (#8 above) — a user in the token-error state can share an empty QR. Everything else looks good.

@arkana-ai-bot thanks. Finding 8 (Share in the token-error state) is already fixed on this head. const shareDisabled =

1 commit since last pass (e7fa58c). 2 of 3 open findings fixed. 1 informational finding remains unchanged.
Prior findings — close-out
Finding #2: plausibleQuote only guards USDT/USDC — Still open, informational, no change
Not touched in this diff. EURC, DAI, PYUSD and any future stablecoin get true with no opinion on the exchange rate. Still a lower-priority follow-up before the provider catalogue widens; not blocking.
Finding #3: EIP-681 extra query parameters / duplicate-field attack — Fixed (e7fa58c)
I originally described this as 'informational — cannot redirect funds.' That was wrong; the commit message explains the correct threat: a malicious LNURL server could return a URI with address=<victim>&address=<attacker>. The old q.get() would return the first value (matching paysQuote), but the full URI would be placed in the QR and some wallet parsers would use the second value. The new only() helper (src/lib/receive/lnurlTokenRails.ts:48–52) uses q.getAll() and returns undefined for any key that appears more than once, making paysQuote return false and the screen fall back to the bare deposit address. The logic is correct for all three bind points: address, uint256, spl-token, and amount (the ?? null on the Solana path correctly propagates to decimal() which will produce a mismatch). Two new test cases added at lnurlTokenRails.test.ts:285–288 directly exercise the duplicate-recipient and duplicate-amount paths. ✓
Finding #8: Share button unguarded in token-error state — Fixed (e7fa58c)
src/screens/Wallet/Receive/QrCode.tsx line 410–416: Boolean(activeToken && !tokenQuote) is now the last term of shareDisabled, matching the existing guard on Copy. The test at receive-lnurl.test.tsx:592–614 enables share.can = true for the error scenario (so !canBrowserShareData does not shadow the assertion), then verifies Share is disabled. The onTestFinished teardown correctly resets the flag so other tests are unaffected. ✓
Incremental diff observations
The diff is narrow and on-point. No new issues to flag.
One minor note on the Solana path: decimal(only('amount') ?? null) — if only('amount') returns undefined (duplicate amount key), the expression becomes decimal(null). This is safe as long as decimal(null) reliably returns something that does not equal decimal(amount) for any valid amount. Worth confirming decimal's null-handling is covered by the existing suite; not a blocker.
Summary
Both actionable findings from the prior pass are fixed. The only outstanding item is the informational plausibleQuote USDT/USDC-only guard, which has been noted across multiple passes as a follow-up. No new issues introduced by this commit.

@arkana-ai-bot Please re-review current head The shared keypad preserves an open amount draft across quote updates/expiry by using semantic asset identity and precision. Real asset/precision changes still reinitialize it. Client 0.7.0 delegation retains the wallet's consent, memo, pricing and quote-lifetime policies. This restack inherits the narrow optional-LNURL fee-delay fix from #1078; this PR's own diff is byte-identical to its preceding published version. The combined tip |

Follow-up pass — 1 commit + several merged feature branches since 2fe42034. 0 prior findings newly closed; 3 informational/low findings remain open. 0 new blocking issues.
Prior findings — close-out
F1 — o.verifiable === true tightening: Fixed (8fab7d5, confirmed in all prior passes). No change here.
F2 — plausibleQuote only guards USDT/USDC: Still open (informational, no change)
src/lib/receive/lnurlTokenRails.ts: if (!['USDT', 'USDC'].includes(unit) || !(requestedUsd > 0)) return true is unchanged. Pre-agreed follow-up before the provider catalogue widens; not blocking.
F3 — EIP-681/Solana Pay extra query parameters: Fixed (2d77a5bb, confirmed in prior passes). No change.
F4 — Copy button silent after a failed quote: Fixed (8fab7d5, confirmed in prior passes). No change.
Low-1 — Missing rel on the deeplink anchor: Still open
src/screens/Wallet/Receive/QrCode.tsx (the TokenQuoteNote component): <a href={quote.value} ...> still has no rel="noopener noreferrer". quote.value is lnurl-client-validated before it reaches this point, and the link is only rendered on mobile when the URI differs from the bare address, so the practical risk is low. Standard hygiene for any server-influenced href; still not a blocker.
Low-2 — Intl.NumberFormat('en') hardcodes locale: Still open (code quality)
src/lib/error.ts: the mapKnownErrors millisats→sats formatter still uses 'en'. Unchanged; not blocking.
Incremental diff — 2fe42034 → ec8b74b1
This increment integrates the LNURL Lightning Address rail (previously reviewed as #1000/#1081), the LNURL activity sync (#1082), and the new fix: allow retrying token receive quotes commit. Notes on each:
Retry feature (fix: allow retrying token receive quotes)
src/screens/Wallet/Receive/QrCode.tsx:
{activeToken && !tokenRails.quoting && (tokenRails.expired || tokenRails.error) ? (
<Button label={t('common.tryAgain')} onClick={tokenRails.regenerate} secondary />
) : null}tokenRails.quoting = Boolean(rail) && !current, so the button appears only once the in-flight request has settled. The expired and error states are mutually exclusive (expired requires current.quote !== undefined; an error means current.quote is absent). Both path coverages are asserted by the two screen-level retry tests in receive-lnurl.test.tsx:
- During retry: Copy disabled, Share disabled, "Try again" absent, old deposit absent. ✓
- After retry settles: new quote and new deposit address shown, old URI not in QR history. ✓
src/lib/receive/lnurlTokenRails.ts: regenerate = useCallback(() => setRound((n) => n + 1), []) increments round, which is in the [source, amountSat, rail?.id, round] effect dep array. The cleanup clears both answer and expiredRound, preventing the old expiry mark from immediately killing the new quote. Previously confirmed correct; still correct here.
LNURL activity sync (src/lib/lnurlActivitySync.ts, src/providers/wallet.tsx)
syncLnurlActivity wraps store writes with an abort-signal guard. Reads (readWatermark) are forwarded unwrapped — idempotent, so harmless post-abort. The pattern is consistent with the docstring: writes stop once signal aborts; a reset closes the store itself to cover writers this wrapper does not own. ✓
In wallet.tsx: syncLnurl is defined as an async closure that captures svcWallet, identity, and signal from the init scope. lnurlResyncRef.current?.cancel() is called in both the lock path (line ~996) and the reset path (line ~1011), preventing stale callbacks after wallet teardown. reloadAfterSync re-checks !signal.aborted before calling reloadWallet, so a locked/reset wallet never gets a reload triggered by a stale sync. The 3 s / 20 s resync schedule in lnurlResyncOnPayment coexists with the 1 s SW-message reload without double-fire issues; cancel() inside onPayment prevents a second payment overlapping the already-scheduled resyncs. ✓
LNURL rail hook (src/lib/receive/lnurlRail.ts, src/screens/Wallet/Receive/LnurlRail.tsx)
useLnurlRail follows the same stale = true cleanup discipline as useLnurlTokenRails. The run() helper uses current.current !== owner (a layoutEffect-updated ref) rather than a closure stale flag — appropriate for imperative button handlers that are not bound to an effect lifecycle. The brief window between setReceiver(owned) and setLoadedFor(facade) (one async boundary apart) leaves status = 'loading' for one render, but receiver?.lnurl is already set at that point so the QR value is correct; the LnurlRailPanel renders null during loading, which is the right transition. ✓
configuredLnurlServer() strips trailing slashes from VITE_LNURL_SERVER (replace(/\/+$/, '')) before any consumer reads the base URL. The server's domain is forced to lowercase. ✓
lnurl: receiver?.lnurl ?? (status === 'loading' ? walletLnurl : undefined) — the wallet-id LNURL (derived locally from encodeLnurl(deriveSessionId(token))) is shown in the QR only during loading, before the server responds. The comment correctly notes that a payer scanning early gets "no longer active" and a retry succeeds. In failed state, status !== 'loading' so walletLnurl is never surfaced after a failure. ✓
In QrCode.tsx, the LNURL-resolved addresses are used in createBip21:
const ark = vtxoTxsAllowed() ? lnurlRails.targets.arkade || recvInfo.offchainAddr : ''
const btc = utxoTxsAllowed() ? lnurlRails.targets.onchain || recvInfo.boardingAddr : ''resolveLnurlRails (in @arkade-os/lnurl-client/arkade) verifies the server-returned address against the wallet's own before putting it in targets; mismatches land in errors instead and the fallback stays the wallet's own address. The error UI (receive.ownAddressInstead) informs the user. Trust-the-library, but the design is correct and the fallback is defensive. ✓
Minor fixes
src/lib/lnurlSends.ts: Array.isArray(parsed) ? parsed : [] guards against corrupted storage. Correct.
src/providers/swaps.tsx: the new early return for swapsOptional correctly skips the onchain claim-fee lookup for LNURL routers that hold the local Lightning client. The existing path (non-optional) is unchanged. ✓
Summary
The retry feature is clean and thoroughly tested at both unit and screen level. The LNURL rail integration (merged from #1081/#1082) follows the same stale-closure and abort-signal patterns established by the token rails. Three pre-existing items remain open (F2, Low-1, Low-2); all are informational or low-severity and unblocking. No protocol-critical paths (VTXO, signing, forfeit, round lifecycle) are touched.

2. plausibleQuote guards only USDT/USDC — Still open, no change
Informational; EURC/DAI/PYUSD get true with no opinion. The test pins that as deliberate. Unchanged in this push; a follow-up issue before the provider catalogue widens is still the right action.
3. EIP-681 extra query parameters pass paysQuote unexamined — Still open, no change
Still informational. Funds cannot be redirected; extra params cannot alter amount. No change in this push.
4. Copy button enabled in token-error state — Fixed (8fab7d5, prior pass)
disabled={generating || Boolean(activeToken && !tokenQuote)} in QrCode.tsx. Unchanged in this push.
Incremental-diff observation — src/lib/i18n.ts
~70 new translation keys, all EN/ES paired — clean.
src/lib/i18n.ts — multiple sections
Every key added to the English dictionary has a corresponding Spanish entry: lightningAddress, resetFailed, receiverConfirmed/receiverNotConfirmed (and their …Text variants), lnurlSentTo/lnurlReceivedAt/lnurlSentVia/lnurlReceivedVia, the payWithToken/gettingQuote/token-quote group, amountBetween, and the full solvers card-info block (viewInfo, cardInfo, remoteChecking, fieldName, etc.). The parity test (i18n.parity.test.ts) traverses leaf keys and will catch any future drift.
unableToFetchLnurl removal — clean.
src/lib/i18n.ts lines (both EN and ES), src/screens/Wallet/Send/Form.tsx
The key is removed from both language blocks. Form.tsx at cc4feb7e no longer calls t('send.unableToFetchLnurl'); the catch path now passes extractError(e) directly. No stale reference remains.
Summary
The two actionable findings from previous passes are fixed and unchanged here. Finding 2 (plausibleQuote scope) remains an open informational note. The incremental content change — i18n additions — is correct. No new issues.

2 new commits since last pass (cc4feb7 → 6433a8d: 3453c5b + 6433a8d). All previously actionable findings are resolved. 2 informational findings remain unchanged.
Prior findings — close-out
Finding #1: verifiable !== false admits verifiable: undefined — Fixed (db16914)
src/lib/receive/lnurlTokenRails.ts: guarded to === true; test row for verifiable: undefined added. ✓
Finding #2: plausibleQuote only guards USDT/USDC — Still open, informational, no change
Not touched in the two new commits. EURC, DAI, PYUSD, and any future USD token receive true with no exchange-rate opinion. Intentionally deferred per @Kukks; not blocking.
Finding #3: EIP-681 extra unknown query parameters — Still open, informational, no change
Not touched in the two new commits. The only() helper (2f9163f) correctly blocks duplicate bound fields. The decision to pass through unrecognised parameters (e.g. memo=) stands as explained; funds cannot be redirected by them, and Copy always takes the bare deposit address. ✓ (informational, intentionally left)
Finding #4: Copy button silent in token-error state — Fixed (db16914)
disabled={generating || Boolean(activeToken && !tokenQuote)} is in place. ✓
Finding #8: Share button unguarded in token-error state — Fixed (2f9163f)
Boolean(activeToken && !tokenQuote) is the last term of shareDisabled. ✓

3453c5b — Keyboard dep array fix
src/components/Keyboard.tsx line 103:
- }, [initialValue, inputMode, asset, toFiat, fiatDecimals])
+ }, [initialValue, inputMode, asset?.assetId, asset?.decimals, toFiat, fiatDecimals])Correct. The initialValue effect only needs to re-run when the asset's identity or decimal count changes, not on every new object reference that parents create during background updates. The decimals change is the important case: if the same asset's precision changed mid-session, the raw bigint stored in initialValue would reformat differently, so a reset is right. Test coverage in keyboard.test.tsx confirms both the asset-swap and the precision-change paths. No issues.

Correct:
qrCodeValueis empty when a token method is active and quoting, but other methods already have values; usingsomeprevents a spurious "loading" flash after address resolution. -
QR button guard:
disabled={generating || !qrCodeValue}— the added!qrCodeValuecorrectly disables tap-to-copy when the token QR has no URI yet.
src/lib/receive/lnurlTokenRails.ts — regenerate
const regenerate = useCallback(() => setRound((n) => n + 1), [])round appears in the quote-request effect's dep array. Incrementing it:
- Triggers effect cleanup:
setAnswer(undefined),setExpiredRound(undefined),clearTimeout(expiry). - Triggers a fresh
requestInvoicecall for the newround. - The
currentguard (answer.asked.round === round) ensures the old answer is never surfaced.
regenerate is stable (useCallback with no deps), so callers do not need to track it as a changing reference. ✓
TokenQuoteNote component
- The
setInterval(1 s)fires whether the expiry is 30 s or 30 min away. This is a minor tick overhead (onesetStateper second while the component is mounted), but the component unmounts as soon as the quote disappears, so it's bounded and not worth changing. Math.max(0, …)prevents displaying−0:01on a slow clock tick. ✓- "Open in wallet" link: gated on
isMobileBrowser && quote.value !== quote.destination. Tron's bare address has no scheme, so no link renders for it. ERC-20 and Solana Pay URIs already passedpaysQuotevalidation; the link is safe. ✓
Test coverage
keyboard.test.tsx: new test covers assetId change and decimals change independently. ✓receive-lnurl.test.tsx:- "offers no token payment actions after the quote expires" — exercises the
visibilitychange-triggered expiry check directly, asserts QR value, Copy, Share, and Open-in-wallet all clear simultaneously. - "retries an expired token quote only on explicit action and hides the old deposit while waiting" — holds the replacement quote in flight, verifies no stale deposit rows are visible, then releases and confirms the new deposit appears.
- Both tests use
onTestFinishedto restorebrowser.mobileandshare.can, so they are correctly isolated. ✓
- "offers no token payment actions after the quote expires" — exercises the
What looks correct overall
The staleness invariant (no quote visible while inputs are in flux) is preserved through the retry path: round is part of Asked, so a quote returned for round N is dropped the moment regenerate fires and round becomes N+1. The cleanup sequence (clear answer, clear expiredRound, clear the expiry timer) runs in the right order before the new effect starts. No double-spend or double-ask vector is introduced.
With receiveViaLnurl and receiveViaTokens both on and an amount set, Receive offers the receiver's LNURL token options (stablecoins a third party swaps to Arkade BTC) beside its bitcoin rails. useLnurlTokenRails lists the options that are up, verifiable, name the provider holding the deposit and accept the amount, and quotes only the one picked, since a quote is a real provider order: re-requested when the amount changes and once it expires. A USD stablecoin quote outside 0.8x to 1.25x of what the sats are worth at the wallet's own price is treated as a misquote. Chain labels follow the BTCPay plugin's names. A token is picked from a sheet with its logo and a chain badge (@web3icons), which also replaces the Arkade mark in the QR centre. The note under the QR says what to send and how long the quote holds; on a phone it links the payment URI to the installed wallet. That URI is used only when it parses as a transfer of the quoted amount, token and chain to the quoted deposit (EIP-681 or Solana Pay), else the bare deposit. Copy takes the deposit address, never the URI, and the copy sheet now offers only the shown method's values; one value is copied outright. The QR stage is height-capped so it sits above the buttons on a short phone. lnurl-client states a rail's bounds in millisats; extractError now says "Amount must be between 10,000 and 100,000,000 sats" (errors.amountBetween). The receiveViaTokens flag defaults off; its toggle ships with the Settings page. Reviewed as #1051 before it merged into #1000. Split out of #1000.
…p Copy off without a quote A token option with no verifiable flag was offered; lnurl-client calls an absent flag unknown, and lnurl-server always states it (true) for its FixedFloat options, so only an explicit verifiable: true is offered now. After a failed token quote the footer Copy stayed enabled but copied nothing, since there is no deposit to copy. It is disabled until the picked token has a quote.
…p Share off without a quote paysQuote read only the first value of each field it binds, so a URI that named a second, conflicting recipient or amount passed while the QR kept the whole URI, and a wallet reading the last value would pay elsewhere. address, uint256, spl-token and amount must now appear exactly once; any repeat falls back to the bare deposit address. Share stayed enabled when the picked token had no quote. It is disabled then, as Copy already is; the token-error test enables browser sharing so the assertion can fail.
paysQuote refuses a URI naming a bound field twice, but only the EIP-681 fields were tested. A Solana Pay quote now has a control that keeps its URI, plus a repeated spl-token and a repeated amount, each of which must show the bare deposit address instead.
…it on request (#1085) * fix(receive): expire a stablecoin quote by the clock, and regenerate it on request Each token quote is a real provider order plus a solver swap, so useLnurlTokenRails no longer places a new one on its own at expiresAt. It marks the quote expired, stops exposing it, and offers regenerate(); a new quote is asked for only when the user taps. A sleeping phone holds setTimeout back, so the quote also counts as expired once Date.now() passes expiresAt, and a visibilitychange re-checks it on wake. offers(sats, id) says whether an option would still be offered for an amount, so a caller can drop a token pick before that amount lands. The hook's tests hold the regenerate request and check that no quote, old or new, is exposed while it is in flight. The Receive screen's expired notice and its "Get a new quote" button come with the receive redesign, which builds on this. Split out of #1068. * fix(receive): keep regenerate stable, and test which options an amount offers regenerate was a new function every render, so a caller using it in an effect or memo would re-run needlessly; it is memoised now. offers() had no direct test: it is false before the payRequest arrives, for an unknown or missing id, and for an amount out of the option's bounds or zero. The cleanup's comment now says why the expiry mark is cleared as well.
…rl-client 0.8.0 tokenOptionAccepts checks an amount against an option's own bounds, and requestTokenQuote asks for the quote, refuses an answer that is not a token destination or that expires too soon, and normalizes the rest; the rails use both instead of repeating them. chainName replaces chainLabels.ts, which mirrored the same BTCPay chain directory. Its test goes too: lnurl-server now checks every chain it offers has a name (test/ff-catalogue.test.ts), and the package tests the fallback to the raw chain id. The wallet keeps its own refusals on top: a deposit that needs a memo the QR cannot carry, base units that are not a canonical positive integer, and a quote far from what the amount is worth.

Pass 3 (897b5d8): 43 commits since last pass — lnurl-client 0.8.0 adoption plus activity/send wiring. 4 of 6 prior findings closed; 2 remain informational (unchanged).
Prior findings — close-out
1. o.verifiable === true — Fixed (8fab7d5)
src/lib/receive/lnurlTokenRails.ts: strict equality in place. Test row ['no verifiable flag', { verifiable: undefined }] present. Still fixed at 897b5d8.
2. plausibleQuote only guards USDT/USDC — Still open, no change
src/lib/receive/lnurlTokenRails.ts lines 34–37: identical to prior pass. Still informational — the test explicitly pins that EURC and other tickers get true unconditionally. No new provider exposure in this diff; the existing acknowledgement is sufficient until the catalogue widens.
3. EIP-681 extra query parameters in paysQuote — No longer applicable
The wallet's paysQuote function (and its URI parsing / Solana Pay validation) moved entirely into @arkade-os/lnurl-client 0.8.0 via commits bda40b9d / 897b5d88 ("refactor(receive): use shared token quote normalization", "take token bounds, quotes and chain names from lnurl-client 0.8.0"). Code no longer exists in the wallet.
4. Copy button silent in token-error state — Fixed (8fab7d5)
src/screens/Wallet/Receive/QrCode.tsx line ~604: disabled={generating || Boolean(activeToken && !tokenQuote)}. Assertion present in receive-lnurl.test.tsx lines 654, 667, 689, 702. Still fixed at 897b5d8.
5. IDB connection leak — Fixed (9fdd8d3, prior catchup)
IDB store creation delegated to createIndexedDbLnurlPaymentStore() in lnurl-client. The wallet-side thin wrapper in src/lib/lnurlPaymentRepository.ts carries no IDB logic, so there is no wallet-owned connection to leak.
6. Address race condition — Fixed (36fba36, prior catchup)
src/lib/receive/lnurlRail.ts lines 78–83: ownArkade / ownOnchain guard in useLnurlRails remains in place at 897b5d8.
Incremental diff — new observations
lnurl-client 0.8.0 adoption scope
The bulk of this diff (commits 7179d0c9–897b5d88) delegates storage, receive bootstrapping, token-quote handling, send tracking, and activity attribution to the library. What the wallet retains:
plausibleQuote— USD price sanity checkMIN_QUOTE_MS/ expiry timer — wallet clock policy- Quote-binding guard in
payLnurl— amount and target verification before signing - Reset ordering — LNURL data cleared before main localStorage
@arkade-os/lnurl-client is pinned to "0.8.0" (exact, no range) in package.json. Good.
payLnurl double-spend guard (src/screens/Wallet/Send/Details.tsx ~254)
const lnurlMeta = lnurlQuoteMeta(quote)
if (lnurlMeta?.target !== target || quote.amount !== satoshis)
return handleError(t('send.quoteForDifferentPayment'))If lnurlQuoteMeta returns null (e.g. the quote has no LNURL metadata), null?.target is undefined, which is !== target, so the guard rejects. Correct. quote.amount === satoshis binds sats exactly. Covered in send-lnurl-route.test.tsx. No issue.
recordLnurlSend → watchLnurlConfirmation timing (Details.tsx ~258–267)
recordLnurlSend(handle, quote, target)
const result = await fundedResult(handle)
if (result?.txid && lnurlMeta.verify)
watchLnurlConfirmation(
result.txid,
lnurlMeta.verify,
lnurlMeta.verifyBatch,
lnurlSends().find((sent) => sent.txid === result.txid)?.createdAt,
lnurlMeta.expect,
)recordLnurlSend writes to localStorage synchronously (the tracker's write path under createLocalStorageLnurlSentPaymentStore). The subsequent lnurlSends().find(...) reads it back before watchLnurlConfirmation is called. The test at send-lnurl-route.test.tsx line 248 asserts startedAt: lnurlSends()[0].createdAt and passes — confirming the read-back is not racy. No issue.
Reset ordering (src/providers/wallet.tsx ~1021)
await clearLnurlPaymentsForReset()
forgetLnurlSends()
await clearStorage()Five commits in this diff (89096eae, f2512ca3, 87498d65, cfc30fc7, 4359f0d5) harden the IDB clear path against abort, reopen, and rejection failures. The wallet-reset-lnurl.test.tsx covers: preimage-purge failure leaving wallet intact, and in-flight send subscriptions being invalidated before localStorage is cleared. Coverage looks solid.
lnurl activity sync abort signal
syncLnurlActivity in src/lib/lnurlActivitySync.ts accepts an AbortSignal and threads it to receiver.sync({ signal }). The wallet passes the per-init signal (aborted on lock/reset) at call sites in wallet.tsx. Correct.
lnurlResyncOnPayment cancel path
The resync controller is held in lnurlResyncRef. The cancel() function clears both delayed setTimeout calls. Neither the sync promise itself nor the onSynced callback holds a reference back into the now-reset wallet — they are scoped to the init closure. Acceptable.
Token rails refactor remains correct
lnurlTokenRails at 897b5d8 imports requestTokenQuote, tokenOptionAccepts, tokenOptions, chainName from lnurl-client 0.8.0. The wallet's own lnurlTokenRails() filter (o.available && o.verifiable === true && o.unit.decimals <= 18 && inBounds) is still applied on top of the library output — the wallet's stricter policy is not overrideable by the library. Good.
Summary
No new actionable findings. The 0.8.0 adoption thins the wallet's LNURL surface without removing any of the money-critical guards (quote binding, expiry, plausible-price check). The one remaining open item — plausibleQuote covering only USDT/USDC — is documented intent.
Offer LNURL token receive rails only after both receive opt-ins and an amount are set. Quote only the selected option, identify the provider holding the deposit, and expose validated deposit details and mobile payment links. Includes merged #1085: expire quotes without placing another order, remove payment actions, and regenerate only when requested.
Use
@arkade-os/lnurl-client0.8.0 for:requestTokenQuote, which also refuses a quote with too little life left);tokenOptionAccepts);chainName). The wallet's own chain-label table and its tests are gone.Keep wallet policies for canonical positive units, required-memo refusal, at least 60 seconds of quote life, supported decimals and the 0.8–1.25 USD price tolerance. Input races, visibility expiry and manual recovery remain in the wallet.
The shared parser deliberately falls back to the validated bare destination for unknown Ethereum arguments/fragments or duplicate Solana memos. A required nonempty memo still makes the quote unusable. Both the older
millisatsand the newwhole millisatsrange errors display readable limits in sats.The shared keypad initializes from semantic asset identity and precision instead of the presentation object's identity. A background quote update therefore preserves an in-progress amount draft; an actual asset or precision change still reinitializes it. Both settings and the receive redesign inherit this fix.
Expired or failed selected token quotes expose an explicit Try again action. Choosing the same token keeps the existing order; only the retry action requests another quote. Two real screen/hook regressions failed before the fix. They now prove expiry and transient-error recovery, selected-rail retention, and unavailable stale payment actions while the replacement response is pending.
Validation at
897b5d88:e89e286cpasses 118 files / 1,339 unit tests and the production build.Base: #1081. Separate children: settings #1084 and receive redesign #1086. No automatic order refresh or storage migration.
