The swap confirmation was fetching a new blockhash after sending the transaction instead of using the one embedded by Jupiter. This mismatch could cause confirmation failures or incorrect transaction status even when the swap succeeded on-chain. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
This still mixes confirmation data from two different blockhash contexts. The patch switches �lockhash to ransaction.message.recentBlockhash, but lastValidBlockHeight is still fetched from a fresh getLatestBlockhash() call after send. Those values need to come from the same context; otherwise confirmTransaction can still report the wrong status or timeout if the chain advances between calls.

Closed as superseded by #75, which reapplies the corrected security hardening on top of current main. This avoids merging stale/conflicted branches and preserves the fixes with passing CI/CodeQL. |
