verify_transaction

ing.crank/crank · Verify this server

Verify any prior transaction signature on demand (FREE read). Post-trade verification (harness spec R13): awaits on-chain confirmation of ``tx_signature`` at ``commitment`` level (up to ``timeout_s``) and, when a state hint is supplied, re-reads the relevant state to compare against what was expected: - ``mint`` (+ ``wallet_address``): re-reads that SPL/SOL token balance. - ``market`` (+ ``wallet_address``): re-reads the Drift perp position. - ``protocol`` (+ ``wallet_address``, optional ``market`` / ``marginfi_account``): re-reads the lending obligation health. Returns ``{confirmed, slot, commitment, post_state, expected_vs_actual, retry_guidance}``. ``confirmed`` is False (never True) on a timeout -- NEVER treat an unconfirmed/timed-out result as success; ``retry_guidance`` names the next step. Use this after signing + broadcasting a transaction yourself (place_perp_order, lend_deposit/borrow/repay, and every other unsigned-tx tool never broadcast server-side) to confirm it actually landed before treating the position/balance as changed.
