Installation

``bash
npm i magic-sdk @magic-ext/zilliqa
`

Setup

Setup TezosExtension with magic-sdk
`js

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'
})
}
});

Usage

$3

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

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

`js
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)
