Error codes / 0x1771
custom program error: 0x1771
Custom(6001) · 0x1771 · used by 33 programs we know
This number has no meaning on its own. Each Solana program numbers its own errors, so 0x1771 is SlippageToleranceExceeded in Jupiter Aggregator v6 but AssertionFailed in Lighthouse. The meaning that applies is the one from the program that actually failed: the first Program … failed line in the transaction's logs. That is often not the program you called, but one it invoked, or a guard instruction your wallet added.
Don't guess: paste the transaction
TxWhy reads the logs, finds the program and the exact instruction that raised 0x1771, explains it, and rebuilds the transaction when the cause is one it can fix.
What 0x1771 means, by program
- SlippageToleranceExceededJupiter Aggregator v6
The swap would have paid out less than the minimum this transaction allowed. The price moved between the moment the quote was taken and the moment the transaction executed, by more than the slippage tolerance set in the swap.
- AssertionFailedLighthouse
The failing instruction is a safety guard added by the wallet or trading app that built this transaction (Lighthouse, the open-source assertion program). What it required was no longer true at execution, so it aborted the whole transaction before anything else ran. This is not Jupiter's slippage error, although it shares the number 0x1771: the state the app previewed (a balance, a pool reserve, or a deadline) changed before the transaction landed.
