Ethers JS RPC methods

ethers.js provides a number of methods for interacting with the Etherdata Network, and we will cover the most common ones in this section.

tip

We will use the mainnet network for this section, but you can use any network you want. Check network info in this section

RPC methods​

set up​

tip

The rest of the docs will be same as the Introduction in Chapter1

  1. Create a folder for your project, we will use test for this example.
  2. Create a file named index.ts in the test folder.
  3. Run npm init -y to create a package.json file.
  4. Run npm install ethers to install ethers.js in your project.
  5. Run npm install @types/node to install @types/node in your project.
  6. Run npm install ts-node to install ts-node in your project.
  7. Run npm install typescript to install typescript in your project.
  8. Run npx tsc --init to create a tsconfig.json file.

After these steps, your project folder should look like this:

test
├── index.ts
├── node_modules
├── package.json
└── tsconfig.json
// package.json
{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "ts-node index.ts"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "ethers": "^5.0.24",
    "ts-node": "^8.10.2",
    "typescript": "^3.9.7"
  },
  "devDependencies": {
    "@types/node": "^14.0.27"
  }
}
// tsconfig.json
{
  "compilerOptions": {
    "module": "commonjs",
    "outDir": "./dist",
    "allowJs": true,
    "lib": ["esnext"],
    "target": "es2017"
  },
  "include": ["./src/**/*"],
  "exclude": ["node_modules", "__tests__"]
}
tip

Now you can use npm start to run your project.

Import ethers​

Put the following code in index.ts:

import { ethers } from "ethers";

Get the provider​

const provider = new ethers.providers.JsonRpcProvider(
  "https://rpc.etdchain.net"
);

Get the block number​

console.log("Current block number", await provider.getBlockNumber());

Get the latest block​

console.log("Latest block", await provider.getBlock("latest"));

Get the transaction by hash​

caution

Replace the transaction_hash with your transaction hash.

console.log("Transaction", await provider.getTransaction("transaction_hash"));

Get the transaction account by wallet address​

caution

Replace wallet_hash with your real wallet address.

console.log(
  "Total number of transactions by wallet address",
  await provider.getTransactionCount("wallet_hash")
);

Get the balance of an account​

const balance = await provider.getBalance("wallet_hash");
console.log("Balance in wei", balance);

Covert balance in wei to balance in ether

const balanceInEther = ethers.utils.formatEther(balance);
console.log("Balance in ether", balanceInEther);

Get the gas price​

const gasPrice = await provider.getGasPrice();
console.log("Gas price in wei", gasPrice);
