EIP-7702 Support

Greg

Features 🚀

We've added beta support for EIP-7702 authorization lists. You can now construct and send 7702 authorizations with the following functions:

• signAuthorization: Generate authorization signatures
• prepareTransaction: Added authorizationList parameter

import {
  signAuthorization,
  prepareTransaction,
  sendTransaction,
} from "thirdweb";
 
const authorization = await signAuthorization({
  request: {
    address: "0x...",
    chainId: 911867,
    nonce: 100n,
  },
  account: myAccount,
});
 
// Preparing a transaction with authorization
const transaction = prepareTransaction({
  chain: chain,
  client: client,
  value: 100n,
  to: recipient,
  authorizationList: [authorization],
});
 
// Sending the authorization transaction
const result = await sendTransaction({
  account,
  transaction,
});

Added deploySmartAccount function to explicitly deploy smart account contracts.

import { deploySmartAccount } from "thirdweb";
 
const account = await deploySmartAccount({
  smartAccount,
  chain,
  client,
  accountContract,
});

Improvements 🔧

Deployed smart accounts now use the legacy signature behavior (ERC-1271) rather than ERC-6492 pre-deploy signatures.
