USAGE

Install SDK

yarn add @omnibtc/omniswap-aptos-sdk

Query All Support Coins

import { App,CoinListClient,CONFIGS } from '@omnibtc/omniswap-aptos-sdk';
import { AptosAccount, AptosClient, HexString } from 'aptos';

const netConf = CONFIGS.testnet;
const client = new AptosClient("https://fullnode.testnet.aptoslabs.com/v1");
const app = new App(client);

(async()=>{
    const coinListClient = await CoinListClient.load(app);
    const coinlist = await coinListClient.getCoinInfoList()
    console.log(`${JSON.stringify(coinlist)}`);
})()
