Deploy L2StandardERC20.sol via the script

You can deploy L2StandardERC20.sol via the following script

const Factory__L2StandardERC20 = new ethers.ContractFactory(
  L2StandardERC20Json.abi,
  L2StandardERC20Json.bytecode,
  L2Wallet
)
const L2StandardERC20 = await Factory__L2StandardERC20.deploy(
  '0x4200000000000000000000000000000000000010',
  L1_TOKEN_ADDRESS,
  TOKEN_NAME,
  TOKEN_SYMBOL,
  TOKEN_DECIMAL
)

ERC20 deposits into L2 can be triggered via the depositERC20 and depositERC20To functions on the L1StandardBridge. You must approve the Standard Token Bridge to use the amount of tokens that you want to deposit or the deposit will fail.

const L1StandardERC20 = new ethers.Contract(
  PROXY__L1STANDARDBRIDGE_ADDRESS,
  L1StandardBridgeJson.abi,
  L1Wallet,
)

const depositTxStatus = await L1StandardERC20.depositERC20(
  L1_TOKEN_ADDRESS,
  '0x4200000000000000000000000000000000000006',
  L1_TOKEN_AMOUNT,
  9999999,
  ethers.utils.formatBytes32String(new Date().getTime().toString())
)
