# PaymentOverflow (/docs/errors/chain/PaymentOverflow)

Arithmetic overflowed while computing the total payment or refund for an EVM transaction, such as refunding remaining gas at the effective gas price. Check for extreme gas price or gas limit values in the transaction.

Declared by the `EVM` pallet; it classifies to the semantic code [`internal`](/docs/errors/internal).
