AccountAbstraction
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);

Methods
estimateUserOperationGas
▸ estimateUserOperationGas(userOperation

Estimate the gas values for a UserOperation. Given UserOperation optionally without gas limits and gas prices, return the needed gas limits.

---|---|---|
userOperation | UserOperation | - |
entryPoint | string | a singleton contract to execute bundles of UserOperations. Bundlers/Clients whitelist the supported entrypoint. |
