Mainchain-Sidechain Transfer

How to Transfer ELA from Mainchain to ESC

1. Using the ELA-CLI, create a deposit transaction:

./ela-cli wallet -t create --deposit eth_address(ESC address) --amount recharge_value(amount ela units) --fee recharge_fee(fee ela units)

2. Sign transaction:

./ela-cli wallet -t sign --file to_be_signed.txn -p yourpassword(your keystore password)

3. Send transaction:

./ela-cli wallet -t send --file ready_to_send.txn

How to Withdraw ELA from ESC to Mainchain

Using node.js

const Web3 = require("web3");

// set web3 uri
const web3 = new Web3("http://127.0.0.1:20636");

// set withdraw contract
let contract = new web3.eth.Contract([
  {
    constant: false,
    inputs: [
      { name: "_addr", type: "string" },
      { name: "_amount", type: "uint256" },
      { name: "_fee", type: "uint256" },
    ],
    name: "receivePayload",
    outputs: [],
    payable: true,
    stateMutability: "payable",
    type: "function",
  },
  { payable: true, stateMutability: "payable", type: "fallback" },
  {
    anonymous: false,
    inputs: [
      { indexed: false, name: "_addr", type: "string" },
      { indexed: false, name: "_amount", type: "uint256" },
      { indexed: false, name: "_crosschainamount", type: "uint256" },
      { indexed: true, name: "_sender", type: "address" },
    ],
    name: "PayloadReceived",
    type: "event",
  },
  {
    anonymous: false,
    inputs: [
      { indexed: true, name: "_sender", type: "address" },
      { indexed: false, name: "_amount", type: "uint256" },
      { indexed: true, name: "_black", type: "address" },
    ],
    name: "EtherDeposited",
    type: "event",
  },
]);

// set eth account address
contract.options.address = deploy_contract_address;

// set account contract keystore info
const acc = web3.eth.accounts.decrypt(keystore_content, keystore_password);

// call receivePayload function，params：(ELA main chain address，amount(In ela up to convert wei 10000000000)，fee)
const cdata = contract.methods
  .receivePayload(ELA_address, withdraw_amount, fee)
  .encodeABI();

// gas minimum is 3000000，gasPrice is any value
let tx = {
  data: cdata,
  to: contract.options.address,
  from: acc.address,
  gas: "3000000",
  gasPrice: "20000000000",
};

// send transaction amount(use receivePayload function amount)
tx.value = withdraw_amount;

acc
  .signTransaction(tx)
  .then((res) => {
    console.log("coming");
    stx = res;
    console.log(stx.rawTransaction);
    web3.eth.sendSignedTransaction(stx.rawTransaction);
  })
  .then(console);
