AccountAbstraction <API>

Account Abstraction feature allows enhancing user experience and security by allowing smart contracts to manage user accounts and transactions more flexibly.

For using account abstraction functions, install web3-account-abstraction packages using: npm i web3-account-abstraction or yarn add web3-account-abstraction.

 import {AccountAbstraction} from 'web3-account-abstraction';

 const aa = new AccountAbstraction('https://bundler-provider');
 aa.supportedEntryPoints().then(console.log);

    Returns undefined | string

  • Will set the default account.

    Parameters

    • val: undefined | string

    Returns void

defaultBlock
