Deploy ERC-20 (Bootstrap)

Use the erc20BaseAbi and erc20BaseBytecode from @cfxdevkit/contracts to deploy a production-ready ERC-20 with one function call.

How it works

erc20BaseAbi + erc20BaseBytecode are exported from @cfxdevkit/contracts — a capped, burnable, pausable ERC-20 with ERC-2612 permit.
wallet.deployContract(abi, bytecode, args) handles signing, broadcasting, and polling for the receipt — returns the deployed address directly.
Constructor arguments: (name, symbol, initialSupply, owner) — the owner receives the full initial supply.

import { EspaceWalletClient, EVM_TESTNET, parseUnits } from '@cfxdevkit/core'
 
const wallet = new EspaceWalletClient({
  chainId:    EVM_TESTNET.id,
  rpcUrl:     EVM_TESTNET.rpcUrls.default.http[0],
  privateKey: '0x...',
})
 
const contractAddress = await wallet.deployContract(
  erc20BaseAbi,
  erc20BaseBytecode,
  ['My Token', 'MTK', parseUnits('1000000', 18), wallet.getAddress()],
)
console.log('Deployed at:', contractAddress)
