# ChainIdMismatch (/docs/errors/chain/ChainIdMismatch)

The order payload's `chain_id` field differs from this chain's configured EVM chain id, e.g. an order signed for testnet was submitted to mainnet. Compare the order's `chain_id` with the runtime's `pallet_evm_chain_id` value and re-sign if needed.

Declared by the `LimitOrders` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
