Error codes / Lighthouse

Lighthouse error codes

Lighthouse is the open-source assertion program wallets and trading apps append to a transaction as a safety guard. When a guard trips, the whole transaction fails with one of these codes; 6001 (0x1771) is by far the most common and is often mistaken for Jupiter's slippage error, which shares the number.
