…f exists Add `ProvedShieldFromAssetLockBundle`, which splits the external-signer `ShieldFromAssetLock` builder into a proving step and an assembly step. `prove` builds and proves the outputs-only Orchard bundle from the locked outpoint alone. The bundle's sighash binds the outpoint, not the asset lock proof: `shield_from_asset_lock_extra_sighash_data` hashes the outpoint for InstantSend and ChainLock proofs alike. So the proof can run before the InstantSend lock exists. `build_transition_with_signer(&self, ..)` recomputes the binding from the real proof and refuses a mismatch. It then signs the proved bundle afresh and has the external signer sign the transition. It does not consume the bundle, so one proof can be wrapped around an InstantSend proof and, after a rejection, around a ChainLock proof of the same outpoint. The binding and padding spend-auth signatures are randomized RedPallas signatures over the sighash fixed at proving time. Two assemblies therefore never produce the same transition bytes, which is what a retry needs to get past Tenderdash's cache of rejected transition hashes. `build_shield_from_asset_lock_transition_with_signer` now goes through the two steps; its output is unchanged. The raw-key builder is untouched. The new API is gated on `core_key_wallet`, like the signer builder. Tests check that: - re-authorized bundles verify with `BatchValidator` and carry distinct binding signatures; - the assembled transitions share one proof around InstantSend and ChainLock proofs, and each assembly is signed afresh; - a different outpoint is refused; - the binding ignores the proof kind and chain-lock height at every protocol version. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… proof wait Add `resolve_funding_observing_out_point` to the asset lock manager. It is `resolve_funding_with_is_timeout_fallback` plus a callback that receives the lock's outpoint as soon as the lock is committed to the operation: - for a new lock, right after the asset-lock transaction is broadcast; - for a resumed lock, once it has passed the consumed and role checks. Either way the callback runs before the InstantSend wait. Two crate-internal wrappers, `create_funded_asset_lock_proof_observed` and `create_funded_asset_lock_proof_with_funding_observed`, carry the hook into the build-broadcast-wait pipeline. The existing entry points pass a no-op, so their behaviour is unchanged. This prepares the shielded flow to start proving while the lock proof is still pending. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…InstantSend lock
Core -> Shielded funding (`shielded_fund_from_asset_lock`) used to wait
for the asset lock's InstantSend lock and only then build and prove the
Orchard bundle, inline on an async worker. Each IS->ChainLock fallback
and each CL-height retry proved a fresh bundle on top of that.
The bundle commits to the locked outpoint and value, not to the lock
proof, and both are known once the asset-lock transaction is broadcast.
Now:
- Start the proof on tokio's blocking pool from the broadcast on, while
the resolver waits for the lock (`resolve_while_proving`). For a
resumed lock, start it once the lock has passed the resolver's checks.
- Reuse the proved bundle for every submission attempt: the first, each
CL-height retry, and the IS->CL fallback (`BundleCache`). A bundle is
reused only for an identical target: same outpoint, same amount, same
protocol version. A speculative proof made for anything else is
discarded and the bundle is proved afresh. Every attempt still signs
the bundle afresh, so resubmissions keep distinct hashes for
Tenderdash's rejected-transaction cache.
- If the resolution fails, the speculative `ProofTask` is dropped:
- a proof that has not started never runs (abort plus a cancellation
flag);
- a running proof's result is dropped when it finishes;
- nothing is persisted.
The sender OVK is now read once, before the resolution, so the
speculative proof and any re-proof commit to the same key. Proving off
the async runtime needs an owned prover, so `P` becomes
`OrchardProver + Send + Sync + 'static`. The FFI entry points and the
seed pool pass `&CachedOrchardProver` (`&'static`).
Measured in the new tests, with the lock arriving one proof-length after
the broadcast:
- fake 400 ms proof and 400 ms lock wait: 810 ms sequential vs 409 ms
overlapped;
- real proof (test profile): 8.06 s vs 4.10 s.

…igning secrets A re-signable proved bundle (`ProvedOutputOnlyBundle`, `ProvedShieldFromAssetLockBundle`) keeps the binding signing key `bsk` and the padding spends' `dummy_ask` and `alpha` inside its signing closure. The funding flow holds the bundle for the rest of the call: possibly through the 300 s InstantSend window and an unbounded ChainLock wait. These secrets are fresh per bundle; no wallet key is among them. They are never serialized, persisted or logged, and are dropped with the `BundleCache`. Anyone holding them could re-bind the proof to another owner and open the per-action value commitments, so document where they live and when they go. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…nts alike The speculative proof took its amount from the tracked row's `amount`: the sum of all the lock transaction's credit outputs. The resolved amount on the InstantSend path is the proof's own output, `credit_outputs[output_index]`. The two agree for the single-output locks the wallet builds. But if they ever diverged, every funding would silently re-prove once the lock arrived, and the overlap would be lost. All paths now read the credit output at the outpoint's index through one helper, `credit_output_duffs`: - the speculative amount, from the tracked transaction; - the InstantSend path, from the proof's transaction; - the ChainLock path, from the tracked transaction. Tests: - a wallet-built lock's only credit output equals both its row amount and the InstantSend proof's output; - with several credit outputs, the indexed output is used, not the sum. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… does Strengthen the test that wraps one proved bundle around an InstantSend proof (twice) and a ChainLock proof of the same outpoint. Each assembled transition's bundle is now rebuilt from its own fields and verified with `BatchValidator`. The sighash comes from that transition's own asset-lock proof, mirroring drive-abci's `shield_from_asset_lock` `transform_into_action` v1 and `reconstruct_and_verify_bundle`: outputs-only flags, `value_balance = -shield_amount`, strict proof size. The test also checks the converse: the same bundle fails under another lock's binding. Adds `nonempty` (already in the lockfile via orchard and drive-abci) as a dpp dev-dependency for `Bundle::try_from_parts`. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Final validation — Phase 1 + Phase 2
The proof-reuse, outpoint-binding, and cancellation paths show no blocking defects. One newly added test should be made manual because its timing assertions can fail under runner load despite correct overlap. This was a static review with no local builds or tests; the supplied CI snapshot shows Rust workspace tests still running, Rust wallet tests skipped, and the Kotlin build/test check failing.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/fund_from_asset_lock.rs:1825-1826: Keep the wall-clock comparison out of the default test suite
This test requires both `proof_started < lock_delivered` and `overlapped < sequential`, so it remains scheduler-dependent despite the comment about avoiding wall-clock bounds. Tokio does not guarantee that the blocking-pool job starts within the simulated 400 ms lock window, and runner load can delay the overlapped sample more than the separately measured sequential sample even when the implementation correctly overlaps the work. Either assertion can therefore cause an unrelated CI failure. The adjacent `should_overlap_the_proof_with_the_lock_wait` test establishes overlap through channel handshakes without comparing performance samples. Keep that regression test in the normal shielded suite and mark this wall-clock comparison as an explicitly manual test.

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete nine-file diff at 3e2c2b1. The prior orchestration and fee-snapshot issues are addressed, but the new reusable DPP API permits unsafe cross-outpoint reuse at protocol versions 12 and 13; discarded queued proofs also have an avoidable cancellation gap. This was static verification only: the supplied CI snapshot still shows Kotlin testing and policy/hygiene checks pending or running and does not establish completed Rust validation for this head.

- [BLOCKING] packages/rs-dpp/src/shielded/builder/shield_from_asset_lock.rs:100-101: Pin the original outpoint independently of the versioned bundle binding
At protocol versions 12 and 13, `credit_pool_bundle_binding` is `None`, so `shield_from_asset_lock_extra_sighash_data` returns an empty vector for every outpoint. This comparison therefore allows a bundle proved for lock A to be assembled and signed around both A and a different lock B. Re-signing preserves the note commitments and the notes' eventual spend nullifiers. Those protocols select `transform_into_action/v0`, which verifies the bundle against an empty preimage, and high-level conversion v0, which does not record the output actions' dummy nullifiers. Consequently, two sufficiently funded locks can be consumed into duplicate notes, but only one copy can be spent. The previous high-level builder produced a fresh bundle on each call; this PR newly exposes unsafe reuse through an exported API that claims to reject another outpoint. The wallet's separate equality guard protects its orchestration, not other DPP callers. Store the original `asset_lock_out_point` in `ProvedShieldFromAssetLockBundle` and require the assembly proof's outpoint to match it independently of the versioned binding comparison. Add a protocol-13 mismatch regression alongside the latest-version test; this needs no consensus-generation change.
In `packages/rs-platform-wallet/src/wallet/shielded/fund_from_asset_lock.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/fund_from_asset_lock.rs:421: Cancel discarded proofs that are still queued
When the speculative outpoint or amount does not match, this wildcard drops its `JoinHandle`, detaching the task before spawning its replacement. Tokio 1.52.3 cannot interrupt an already-running blocking task, but `abort()` can prevent a queued blocking task from starting. With a saturated or bounded blocking pool, the obsolete proof can remain ahead of its replacement and consume proving CPU and memory despite its result already being unusable. Abort the discarded handle before spawning the replacement; already-running proofs retain the documented detach behavior. Cover the queued case deterministically by occupying a single-thread blocking pool, enqueueing speculation, discarding it, and checking that its proving closure does not run after the pool is released.
…l version Before protocol 14 the ShieldFromAssetLock sighash binds nothing, so comparing bindings let one proved bundle be assembled around two different asset locks, funding the same note twice. The proved bundle now keeps the outpoint it was proved for and refuses any other, whatever the version binds. The wallet also aborts a discarded speculative proof, so one still queued on the blocking pool never runs. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete nine-file diff at 8c1a44d and found no remaining blocking issues. The prior outpoint-binding and orchestration defects are addressed; two non-blocking suggestions remain concerning queued proofs on early error exits and independent cross-version binding coverage. Validation was static only: the supplied CI snapshot at 2026-10-09T19:23:32Z showed Kotlin SDK build/tests and PR Hygiene pending, with no completed Rust-test check.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/fund_from_asset_lock.rs:323-328: Abort queued speculative proofs on early error returns
Once speculation has spawned its blocking task, `speculative` owns a plain Tokio `JoinHandle`. If `resolution?` returns an error, dropping that handle detaches the task rather than cancelling queued work. Errors from the ChainLock fallback at line 342 and the resolved amount lookup at line 371 also bypass the later `abort()` branch. With a saturated or bounded blocking pool, a failed operation can therefore leave an unnecessary Halo 2 proof queued ahead of a subsequent resume. Abort the speculative handle on these error exits, or give it an abort-on-drop owner that preserves ownership through the successful reuse path. Already-running proofs can retain the documented detach behavior. A deterministic single-slot blocking-pool test can verify that a queued proof does not execute after resolution fails.
In `packages/rs-dpp/src/state_transition/state_transitions/shielded/shield_from_asset_lock_transition/signing_tests.rs`:
- [SUGGESTION] packages/rs-dpp/src/state_transition/state_transitions/shielded/shield_from_asset_lock_transition/signing_tests.rs:440-442: Cover same-outpoint assembly across the binding-version boundary
Both new assembly tests use the proving version for every assembly, and their rejected cases supply a different outpoint. Those cases short-circuit at the stored-outpoint check, so removing the `extra_sighash_data` comparison would leave these tests passing. Extend this protocol-13 test to assemble the already-proved bundle around its original outpoint using `PlatformVersion::latest()`, and assert the binding-mismatch error. Protocol 13 selects an empty binding, while the latest version selects `Some(0)` and binds the outpoint. Without this independent check, the public API could assemble a transition whose bundle signatures use the historical empty preimage instead of the preimage consensus verifies. This regression requires no additional proof generation or version-table changes.
The speculative proof's handle detached on drop, so a funding that failed after speculation started (resolution error, ChainLock fallback, amount lookup) left its proof queued on the blocking pool. Proof handles now abort on drop, which also covers the discarded-speculation case the explicit abort handled. A running proof still cannot be interrupted. The protocol-13 proved-bundle test now also assembles around the bundle's own outpoint at the latest version and expects a binding mismatch, so the binding comparison is covered independently of the outpoint check.

- Around line 825-826: Recheck `sdk.version().protocol_version` after
`build_transition_with_signer(...).await` and before broadcast, ensuring it
still matches `platform_version.protocol_version`. Also enforce the same
expected-version check when the broadcast request executes, rather than relying
only on retries.

Re-review — Final validation — Phase 1 + Phase 2
The prove/assemble split preserves outpoint binding and consistently uses one protocol-version snapshot for pricing and assembly; no in-scope consensus blockers were confirmed. One cancellation-lifetime suggestion remains: mismatched speculative work is retained instead of dropped before its replacement starts. This was a static review; the exact-head CI snapshot reports successful Rust workspace and Swift/Kotlin checks, with the dedicated Rust wallet job skipped and PR Hygiene pending.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/fund_from_asset_lock.rs:424-425: Cancel discarded proofs that are still queued
(existing thread: https://github.com/dashpay/platform/pull/5282#discussion_r4233684688)
The earlier explicit abort handled this case, but the abort-on-drop refactor replaced its consuming fallback with `_`. Because `speculative` is a named local, this wildcard neither moves nor drops its value, and the guarded arm does not move the handle when its guard fails. The rejected `AbortOnDropHandle` therefore remains owned until the funding function exits, including while the replacement proof and submission retries are awaited. An obsolete proof queued on a saturated blocking pool can consequently start ahead of its replacement and perform unnecessary Halo 2 work; a completed obsolete result also remains retained. Bind and explicitly drop the fallback value before spawning the replacement. A drop-order regression can verify this wallet-owned lifetime without needing to retest Tokio's cancellation implementation; already-running blocking proofs remain noninterruptible.
A `_` arm does not move `speculative`, so a proof made for another outpoint or amount stayed owned until the funding call returned and could still start ahead of its replacement. Move it out and drop it first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-review — Final validation — Phase 1 + Phase 2
Independently verified the complete 11-file diff at the exact head and found no remaining in-scope defects: bundle reuse checks the original outpoint and versioned binding, speculative proofs retain abort-on-drop ownership, and pricing, proving, and assembly share one protocol-version snapshot with a post-signing check. Ten prior findings are fixed; the indexed-output coverage request is withdrawn because its targeted implementation was removed and the retained ChainLock amount source matches base. Validation was static only; git diff --check passed, while the supplied CI snapshot still showed Rust workspace validation pending and the dedicated Rust wallet tests skipped.

Core → Shielded funding (
shielded_fund_from_asset_lock, state transition type 18) waits for the asset lock's InstantSend lock, and only then builds and proves the Orchard bundle. That is seconds of Halo 2 work, run inline on an async worker. Every IS → ChainLock fallback and every CL-height retry (15 s apart) proves a fresh bundle again.The bundle doesn't depend on which lock proof is used, so the proving time can overlap the lock wait, and fallbacks and retries can skip proving.
This is part of a series cutting Dash shielded send latency. The others are #5277, #5278, #5279, #5280 and #5281, dashpay/halo2#1–#3, dashpay/orchard#12 and #13, and dashpay/dashwallet-ios#1183.

There is no second proving path.ProvedShieldFromAssetLockBundle::prove(.., out_point, ..)proves from the outpoint alone.build_transition_with_signer(&self, ..)refuses a lock proof of any outpoint other than the one it was proved for. That check stands on its own, because before protocol 14 the sighash binds nothing and would accept one bundle around two locks, funding the note twice. It also re-derives the binding from the real lock proof and refuses a protocol version that binds differently. Then it re-signs. RedPallas signatures are randomized, so resubmissions keep distinct hashes and aren't dropped by Tenderdash's rejected-transaction cache.build_shield_from_asset_lock_transition_with_signeris unchanged.platform-wallet:

The shielded flow joins resolution with a future that reads the tracked lock's value and starts the proof withspawn_blocking, so the proof runs while the InstantSend lock is awaited.bskand the padding keys are fresh per bundle and are never serialized, persisted or logged. They are held from proving until the submission attempts end, which includes the lock wait (withcl_wait = None, an unbounded ChainLock wait). Misusing them could only re-fund the same note under another lock.Saves about min(proof time, InstantSend latency) per funding, plus a whole proof per fallback or retry.
One protocol version: a single
PlatformVersionsnapshot, taken after the lock is chosen, prices the pool fee, proves the bundle and assembles every attempt. If the SDK's protocol version has moved by the time a signed attempt is about to be broadcast (checked after signing, which an external signer can stretch out), it refuses rather than submitting a bundle priced under the old fee schedule (with no surplus output, a fee overpayment would go to the pools). The tracked lock is untouched, so a resume re-proves.Known edge: if the SDK's protocol version crosses a
credit_pool_bundle_bindingchange between proving and submitting, assembly refuses with a binding-mismatch error rather than submitting a transition consensus would reject.How Has This Been Tested?

Rust API only:
PlatformWallet::shielded_fund_from_asset_locknow requiresP: OrchardProver + Copy + Send + 'static(pass&CachedOrchardProver). Callers that passed a borrowed, non-'staticprover must change. In-repo callers (FFI, seed pool) are updated. The C ABI is unchanged.Follow-up with #5278, whichever lands second: route this speculative proof through #5278's
ShieldedProver::ready(),on_proving_threads(Apple user-initiated QoS pool) and its proving gate. Until then it proves on the blocking pool via the global rayon pool. That is still off the async runtime, but it isn't QoS-pinned or serialized with other proofs. No text conflict is expected.Checklist:
