Features

• All-In-One

• UserOperation can be built with a single function

• Built-in Bundler module

• Built-in common operations, such as ERC20 ERC721 ERC1155 (e.g. you can create a transfer UserOperation with one function)

• Auto update preVerificationGas (lower deposit requirements for user)

• ⚠️ Note: current version will refactor the code in the future and cannot guarantee compatibility

Installing

Using npm:

$ npm install git+https://github.com/PlatONnetwork/platrust-wallet-js-sdk.git#v0.1.0

Using yarn:

$ yarn add git+https://github.com/PlatONnetwork/platrust-wallet-js-sdk.git#v0.1.0

Using pnpm:

$ pnpm add git+https://github.com/PlatONnetwork/platrust-wallet-js-sdk.git#v0.1.0

Once the package is installed, you can import the library using import approach:

import { ApproveToken, ParsedTransaction, walletLib, UserOperation } from 'platrust-wallet-js-sdk';

Example

import { ethers } from "ethers";
import { Accounts } from "web3-eth-accounts";
import { UserOpReceipt, walletLib, UserOperation, packSignatureHash, signMessage, encodeSignature } from 'platrust-wallet-js-sdk';
