​
VerifySignature()

VerifySignature(deps): (tx) => boolean
Defined in: src/primitives/Transaction/EIP2930/verifySignature.js:43 Factory: Verify EIP-2930 transaction signature. Verifies that the transaction signature is valid. This checks that:
  1. The signature components (r, s) are well-formed
  2. The yParity is valid
  3. A public key can be recovered from the signature
Note: This does NOT verify the transaction was signed by a specific address. It only validates the signature is cryptographically valid and can recover a sender address. To verify against an expected sender, use getSender() and compare the result.

​
Parameters

deps
Crypto dependencies
keccak256
(data) => Uint8Array Keccak256 hash function
rlpEncode
(data) => Uint8Array RLP encode function
secp256k1RecoverPublicKey
any secp256k1 public key recovery

​
Returns

Function that verifies signature
(tx): boolean
Parameters
tx
TransactionEIP2930Type
Returns
boolean
