custom program error: 0x1780
What it means
The program raised this named error and published no further explanation.
What to do
The error name is the program's own diagnosis. Paste the failed transaction into TxWhy to see which instruction raised it and with which accounts.
Seen on mainnet
The buy asks for more of the token than the pool holds. Buy less; nothing moves the pool's reserves for you. TxWhy refuses this one with the figure rather than retrying it.
From replaying real landed failures through the repair engine, around the clock since September 21, 2026. Every verdict and its reason is on the failure index.
Have the transaction that failed with this?
Paste its signature. TxWhy shows the exact instruction and inner call that raised the error, and rebuilds the transaction when the cause is one it can fix (compute limit, expired blockhash, priority fee, a stale swap quote or a moved limit).
Code 6016 means something else in other programs
Custom codes are private to each program. Check which program actually raised it: it is the innermost failed call, not necessarily the program you called.
