What the error means
Computational budget exceeded
The transaction ran out of compute units. Each instruction gets 200,000 by default and a transaction can use at most 1,400,000.
| Where it comes from | Solana runtime (instruction error) |
| Code | ComputationalBudgetExceeded |
How to fix it
- Raise the compute unit limit with a SetComputeUnitLimit instruction, up to 1,400,000 per transaction. Many wallets and bots do this for you with a "compute" or "CU" setting.
- Split a large action into several transactions, for example fewer recipients per airdrop transaction or fewer bins per liquidity add.
- If you set the limit yourself, simulate first and use the units consumed plus a margin.
If that is not it
- If the limit is already at 1,400,000, the transaction does too much work for one transaction and must be split.
