Magic Extension Zilliqa blockchain

Installation

npm i magic-sdk @magic-ext/zilliqa

Setup

Setup TezosExtension with magic-sdk

import { Magic } from 'magic-sdk';
import { ZilliqaExtension } from '@magic-ext/zilliqa';
const { BN, Long, bytes, units } = require('@zilliqa-js/util');

const magic = new Magic('YOUR_API_KEY', {
    extensions: [
        new ZilliqaExtension({
            rpcUrl: 'zilliqa rpc url'
        })
    ]
});

// or


const magic = new Magic('YOUR_API_KEY', {
    extensions: {
        zilliqa: new ZilliqaExtension({
            rpcUrl: 'zilliqa rpc url'
        })
    }
});

Magic SDK

See the developer documentation to learn how you can master the Magic SDK in a matter of minutes.

Usage

Get wallet

Using wallet function to get Zilliqa public key, and address for current user.

const wallet = await magic.zilliqa.getWallet();
console.log('zilliqa wallet', wallet);

Send Transaction

      const handlerSendTransaction = async () => {

          const chainId = 333; // chainId of the developer testnet
          const msgVersion = 1; // current msgVersion
          const VERSION = bytes.pack(chainId, msgVersion);

          const myGasPrice = units.toQa('1000', units.Units.Li);

          const params = {
              version: VERSION,
              toAddr: "zil14vut0rh7q78ydc0g7yt7e5zkfyrmmps00lk6r7",
              amount: (new BN(units.toQa('0.5', units.Units.Zil))), // Sending an amount in Zil (1) and converting the amount to Qa
              gasPrice: myGasPrice, // Minimum gasPrice veries. Check the `GetMinimumGasPrice` on the blockchain
              gasLimit: Long.fromNumber(1),
          };

          const tx = await magic.zil.sendTransaction(
              params,
              false,
          );

          console.log('send transaction', tx)
      };
