func VerifyEthereumSignature ¶

func VerifyEthereumSignature(
	t *testing.T,
	hash []byte,
	signature *ecdsa.Signature,
	expectedPublicKey *ecdsa.PublicKey,
)

VerifyEthereumSignature validates that signature in form (r, s, recoveryID) is a valid ethereum signature. `SigToPub` is a wrapper on `Ecrecover` that allows us to validate a signature in the same way as it's done on-chain, we extract public key from the signature and compare it with signer's public key.
