Quick Start
The quickest way to start minting and burning tokenized Bitcoin on Ethereum with RenJS.
This is a quick-start guide with minimal code snippets for minting and burning Bitcoin on Ethereum.
This assumes window.ethereum is available (e.g. in a browser with MetaMask installed). See hdwallet-provider and infura.io if you are using RenJS using Node.js instead of in a browser.
yarn add @renproject/ren @renproject/chains ethers
import { Bitcoin, Ethereum } from "@renproject/chains";import RenJS from "@renproject/ren";import { ethers } from "ethers";​const mint = async () => {await window.ethereum.enable();const provider = new ethers.providers.Web3Provider(window.ethereum);provider.getSigner();const signer = provider.getSigner();const address = await signer.getAddress();​const lockAndMint = await new RenJS("testnet").lockAndMint({asset: "BTC",from: Bitcoin(),to: Ethereum(provider.provider).Address(address),});​console.log(`Deposit BTC to ${lockAndMint.gatewayAddress}`);​lockAndMint.on("deposit", RenJS.defaultDepositHandler);};​mint().catch(console.error);
import { Bitcoin, Ethereum } from "@renproject/chains";import RenJS from "@renproject/ren";import { ethers } from "ethers";​const burn = async () => {await window.ethereum.enable();const provider = new ethers.providers.Web3Provider(window.ethereum);const value = 2000000; // sats​const burnAndRelease = await new RenJS("testnet").burnAndRelease({asset: "BTC",to: Bitcoin().Address("miMi2VET41YV1j6SDNTeZoPBbmH8B4nEx6"),from: Ethereum(provider.provider).Account({ value }),});​await burnAndRelease.burn();await burnAndRelease.release();};​burn().catch(console.error);
