# InvalidSignature (/docs/errors/chain/InvalidSignature)

Signature verification failed: the sender of an Ethereum or EVM transaction could not be recovered from its signature, or a limit order's Sr25519 signature does not match the order payload and signer. Check the signing key, chain id, and the exact payload bytes that were signed.

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

## Remediation [#remediation]

Check the argument values against the operation schema

The same explanation is available in the terminal: `btcli explain InvalidSignature`.
