import { suggestFees } from './src';
const main = async() => {
const provider = new JsonRpcProvider(`https://ropsten.infura.io/v3/${YOUR_API_KEY}`);
const ret = await suggestFees(provider);

import { JsonRpcProvider } from '@ethersproject/providers';
import { suggestFees } from './src';
const main = async() => {
const provider = new JsonRpcProvider(`https://ropsten.infura.io/v3/${YOUR_API_KEY}`);
const fromBlock = 'latest' // the block that you want to run the estimations from
const blockCountHistory = 100 // the quantity of blocks you want to take in account for the estimation
const ret = await suggestMaxBaseFee(provider, fromBlock, blockCountHistory);
console.log('Result: ', ret);
}
main();
import { JsonRpcProvider } from '@ethersproject/providers';
import { suggestFees } from './src';
const main = async() => {
const provider = new JsonRpcProvider(`https://ropsten.infura.io/v3/${YOUR_API_KEY}`);
const fromBlock = 'latest' // the block that you want to run the estimations from
const ret = await suggestMaxPriorityFee(provider, fromBlock, blockCountHistory);
console.log('Result: ', ret);
}
main();
The suggestMaxBaseFee
estimations code is 100% based on the work of @zsfelfoldi published at https://github.com/zsfelfoldi/feehistory/
