Computes the Keccak256 hash of the RLP-encoded transaction fields that need to be signed. The transaction uses BrandedAddress for `to` field, assumed to be validated (20 bytes).

Verifies that the transaction signature is valid. This checks that: 1. The signature components (r, s) are well-formed 2. The yParity/v 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 [`TransactionEIP1559Type`](#transactioneip1559type) ##### Returns `boolean` #### See [https://voltaire.tevm.sh/primitives/transaction](https://voltaire.tevm.sh/primitives/transaction) for Transaction documentation #### Since 0.0.0 #### Throws Never throws - returns false on error #### Example ```javascript theme={null} import { VerifySignature } from './primitives/Transaction/EIP1559/verifySignature.js'; import { hash as keccak256 } from '../../../crypto/Keccak256/hash.js'; import { encode as rlpEncode } from '../../Rlp/encode.js'; import { recoverPublicKey } from '../../../crypto/Secp256k1/index.js'; const verifySignature = VerifySignature({ keccak256, rlpEncode, secp256k1RecoverPublicKey: recoverPublicKey }); const isValid = verifySignature(tx); ```
