SPL Token Swap · Custom(16) · 0x10
custom program error: 0x10
What it means
Swap instruction exceeds desired slippage limit
What to do
Increase your slippage tolerance or reduce the trade size, then retry — the price moved between quote and execution.
TxWhy can repair this one
When the swap was routed through Jupiter, TxWhy replaces only the stale swap instruction with a current quote for the same tokens, amount and slippage tolerance, keeps every other instruction byte for byte, and proves the result passes simulation.
Code 16 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.
