@choko-wallet/token-price
This is a pre-built lib contains tokeninfo
Step 1:
Fetch top marketcap tokens/coins
https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&order=market_cap_desc&per_page=250&page=1&sparkline=false&locale=en
Step 2:
Fetch Token Contract Info:
https://api.coingecko.com/api/v3/coins/${info.coingeckoId}
Script:
import { tokenInfo } from './tokenInfo';
import superagent from 'superagent'
import fs from 'fs'
import { sleep } from '@skyekiwi/util'
const main = async() => {
for (let i = 0; i < 250; i ++) {
if ( fs.existsSync(`./res/${i}.json`) ) {
continue;
}
const info = tokenInfo[i];
const result = await superagent
.get(`https://api.coingecko.com/api/v3/coins/${info.coingeckoId}`);
const tokenData = JSON.parse(result.text);
const ethereumAddress = tokenData.platforms['ethereum'];
const bnbAddress = tokenData.platforms['binance-smart-chain'];
const polygonAddress = tokenData.platforms['polygon-pos'];
const r = {
...info,
contractAddress: {
1: ethereumAddress,
56: bnbAddress,
137: polygonAddress
}
}
fs.writeFileSync(`./res/${i}.json`, JSON.stringify(r, null, 2));
await sleep(5000)
}
}
main()
The above script will products a a bunch of json files that contains each token/coin
Step 3 Combine those JSON into a single file.
let res: TokenData = {};
for (let i = 0; i < 250; i ++) {
const content = fs.readFileSync(`./res/${i}.json`);
const info = JSON.parse(content.toString());
res[info.coingeckoId] = info;
}
fs.writeFileSync(`./res/all.json`, JSON.stringify(res, null, 2));
