getAuthorizer()

static getAuthorizer: (auth) => AddressType

Defined in: src/primitives/Transaction/Authorization/Authorization.js:55 Get authorizing address from signature. Recovers the Ethereum address that signed the authorization using the signature components (r, s, yParity) and the signing hash.

Parameters

auth

BrandedAuthorization Authorization to recover from

Returns

AddressType Recovered authorizer address

See

https://voltaire.tevm.sh/primitives/transaction for Transaction documentation

Since

0.0.0

Throws

If signature recovery fails

Example

import { getAuthorizer } from './primitives/Transaction/Authorization/getAuthorizer.js';
const authorizerAddr = getAuthorizer(auth);

getSigningHash()

static getSigningHash: (auth) => HashType

Defined in: src/primitives/Transaction/Authorization/Authorization.js:53 Get signing hash for authorization (EIP-7702). Per EIP-7702: keccak256(MAGIC || rlp([chain_id, address, nonce])) MAGIC = 0x05

Parameters

auth

BrandedAuthorization Authorization to hash

Returns

HashType Signing hash

See

https://voltaire.tevm.sh/primitives/transaction for Transaction documentation

Since

0.0.0

Throws

Never throws

Example

import { getSigningHash } from './primitives/Transaction/Authorization/getSigningHash.js';
const hash = getSigningHash(auth);

verifySignature()

static verifySignature: (auth) => boolean

Defined in: src/primitives/Transaction/Authorization/Authorization.js:54 Verify authorization signature. Validates that the signature (r, s, yParity) is valid for the authorization’s signing hash by recovering and verifying the public key.

Parameters

auth

BrandedAuthorization Authorization to verify

Returns

boolean True if signature is valid

See

https://voltaire.tevm.sh/primitives/transaction for Transaction documentation

Since

Throws

Never throws - returns false on error

Example

import { verifySignature } from './primitives/Transaction/Authorization/verifySignature.js';
const isValid = verifySignature(auth);
