[w0dm4n]

Hello, the following code result in a few seconds complete freeze until the result come in which mean that javascript is overloaded and getting totally fucked for a little while, how is that even possible ?)

import { Fetcher, Route } from '@uniswap/sdk'
        const netId = await web3.eth.net.getId();
        const PTE = await Fetcher.fetchTokenData(netId, web3.utils.toChecksumAddress(Env().PEET_CONTRACT_ADDR));
        const USDT = await Fetcher.fetchTokenData(netId, web3.utils.toChecksumAddress(Env().USDT_CONTRACT_ADDR));
        
        const pair = await Fetcher.fetchPairData(PTE, USDT);
        const route = new Route([pair], USDT)
