Problem

Asset swaps do not show up in the activity list, on every browser.

createOffer registers the offer covenant as a contract of this wallet, and the SDK's getTransactionHistory folds every contract's vtxos into the wallet's set. buildTransactionHistory then counts the covenant output as change, so the funding tx nets to zero and emits no row. A cancel returns the same sats to the same wallet and nets to zero too. Only a fill produces a row, keyed on the fill txid.

Run against the SDK's own buildTransactionHistory with synthetic vtxos:

Scenario Rows for the swap
BTC to asset, pending none
BTC to asset, cancelled none
BTC to asset, fulfilled one SENT keyed on the fill txid

So a pending, cancelled or recoverable swap has no activity group at all. The list never shows it, and nothing can be cancelled from the UI. Same mechanism the wallet already documents for the Lightning lockup contract (ungroupedLnSendTx).

Fix

activitiesToTxs builds the row from the swap record when no group carries its id, under the key the group would carry so a fill replaces it rather than doubling it. Four new cases in activityHistory.test.ts.

Relationship to the SDK

This is a wallet-side compensation. The root cause is in the SDK and is addressed in arkade-os/ts-sdk#853. Once that ships and the wallet bumps, the funding tx comes back as a SENT row and this record-only path stops firing for open offers. It stays useful for the window between a record write and the next history refresh, the same way ungroupedLnSendTx does.

Split out of #954, which now carries only the Safari IndexedDB fix.

Not fixed here

  • The restore scan (restoreAssetSwaps) needs the funding tx as a sent row to find the offer packet, so a restored wallet still cannot rebuild swap records until the SDK fix lands.
  • The swap e2e tests have been test.skip since Lightning over Arkade RFQ; remove Boltz #908; they would have caught this.

Validation

Unit suite green: 89 files, 773 tests. Lint and prettier clean.

Summary by CodeRabbit

  • Bug Fixes
    • Asset swaps now appear in activity history even when they are missing from the underlying history feed.
    • Pending, cancelled, and recoverable swaps are represented consistently until a completed swap activity becomes available.
    • Swap records are deduplicated when matching history entries arrive, preventing duplicate entries.
    • Available transaction metadata, such as network and asset display details, is retained for record-only swap entries.

createOffer registers the offer covenant as a contract of this wallet,
and getTransactionHistory folds every contract's vtxos into the wallet's
set. buildTransactionHistory then counts the funding output as change,
so the funding tx nets to zero and emits no row; a cancel returns the
same sats to the same wallet and nets to zero too. Only a fill produces
a row, keyed on the fill txid. A pending, cancelled or recoverable swap
therefore had no row at all, in every browser: the activity list never
showed it and nothing could be cancelled from the UI.

Same mechanism, same answer as ungroupedLnSendTx: when no activity
group carries the swap id, build the row from the record, under the key
the group would carry so a fill replaces it rather than doubling it.

Review Change Stack

Walkthrough

activitiesToTxs now creates history rows for asset swaps that lack Arkade activity groups. It avoids duplicate rows for grouped swaps and attaches funding transaction metadata. Tests cover pending, cancelled, completed, and metadata-enriched swaps.

activitiesToTxs creates rows for ungrouped swaps, skips swaps already present in history, and grafts funding transaction metadata. Tests cover pending, cancelled, completed, deduplicated, and metadata-enriched rows.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 134e9

This change can display fulfilled swaps without their fill transaction details when the activity group is absent, resulting in an incorrect activity-history entry. The fulfilled-swap fallback path should be excluded before merge.

Skip fulfilled swaps in the record-only fallback.

If a fulfilled swap is missing from activities, this condition passes and the next lines call buildAssetSwapActivityTx(swap, []). The result has amount: 0 and no fill transaction members, so it is not the fill transaction row required by this history contract.

Limit this fallback to pending, cancelled, and recoverable swaps. Add a regression test in src/test/lib/activityHistory.test.ts for a fulfilled swap with no activity group.

-    if (groupedSwaps.has(swap.id)) continue
+    if (groupedSwaps.has(swap.id) || swap.status === 'fulfilled') continue

Arkana review — PR #955 (display fix: ungrouped asset swap rows)

Scope: display layer only — no protocol paths, no VTXO handling, no signing, no forfeit or round logic. Not protocol-critical.


Summary

The patch correctly mirrors the existing ungroupedLnSendTx pattern for asset swaps. The mechanism is sound: groupedSwaps is built from the same swapIdOf predicate the main loop uses, historyKey: \swap:${swap.id}`matches the resolver's group ID so a fill replaces rather than doubles the record-only row, andgraftMetadata` handles a missing metadata entry safely. The four new test cases cover the cases that matter: record-only pending, cancelled (cancel tx nets to zero too), dedup when history arrives, and metadata grafting.


Findings

Minor — amount: 0 on ungrouped swap rows (src/lib/activityHistory.ts:305)

buildAssetSwapActivityTx(swap, [], …) is called with an empty members slice.
Inside that function:

amount: members[0]?.amount ?? 0,  // → 0 when members is []

ungroupedLnSendTx handles the equivalent by reading send.amount from the record directly. For the swap case the record's fromAmount (a string, always in the BTC-leg's sats) is available and could fill that slot. The top-level amount is not used by sortLocalTxs (sorts on createdAt) and swap-specific display reads assetSwap.fromAmount/assetSwap.toAmount, so this is likely not user-visible in the swap receipt or route label. Worth double-checking whether any generic list renderer (e.g. an amount column for non-swap row types that might also render type: 'swap') falls back to the top-level amount.

Nit — test fixture decouples id from fundingTxid (src/test/lib/activityHistory.test.ts:39-53)

id: 'swap-1',          // ≠
fundingTxid: 'funding-txid',

The package's own JSDoc says id is "Funding txid — the swap's identity", so in production id === fundingTxid. The tests still exercise the correct code path with distinct values, but aligning them (id: 'funding-txid', fundingTxid: 'funding-txid') would rule out any future confusion about whether the two fields can diverge.


Observations (no action required)

  • Transitional design acknowledged. The PR body and the code comment both explain that this is a wallet-side compensation until ts-sdk#853 ships. The same comment covers the window between a record write and the next history refresh, matching the existing ungroupedLnSendTx rationale exactly.
  • Dedup is tight. groupedSwaps captures the swap ID even when the group falls through to plain member rows (the "record not there yet" path at line 265); the ungrouped path then correctly skips it.
  • Cancelled swap row is consistent. buildAssetSwapActivityTx sets fillTxid for both fulfilled and cancelled statuses, so a cancelled swap shows its cancel txid in both redeemTxid and assetSwap.fillTxid, which matches what a cancel receipt would expect.
  • Restore gap documented. The "Not fixed here" section in the PR body correctly identifies that restoreAssetSwaps still cannot rebuild swap records without the SDK fix.
