# InvalidChainId (/docs/errors/chain/InvalidChainId)

The EIP-155 chain id encoded in the signed transaction does not match this chain's configured chain id. Compare the transaction's chain id with the value returned by `eth_chainId` and re-sign the transaction.

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