EVM submission handling rechecks wallet state and distinguishes unknown outcomes. Polling requires exact event and receipt corroboration before recovery. The UI blocks duplicate submissions and supports automatic or manual resolution. ChangesUnknown unwrap recovery
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR strengthens protection against duplicate EVM unwrap submissions by persisting safety records and failing closed on ambiguous provider failures. A bounded residual risk remains because automatic recovery can release the safety lock before the matched transaction reaches finality, so a chain reorganization could briefly permit a duplicate retry; maintainer awareness or follow-up is recommended.

hydrateUnknownSourceOperationsagainst out-of-order results.
onLocksChangedcalls this function on every store mutation, so several hydrations can run concurrently. Each one awaits an async storage read, so a stale result can resolve last and overwrite the newer arrays. That reinstates a record that was already cleared.
