# hardhat-ethers
2+
3+
[Hardhat](https://hardhat.org) plugin for integration with [ethers.js](https://github.com/ethers-io/ethers.js/).
4+
5+
### Usage
6+
7+
```ts
8+
const { ethers } = await hre.network.connect();
9+
10+
// ethers functionalities
11+
ethers.isAddress("0x1234567890123456789012345678901234567890");
12+
13+
// ethers.Provider
14+
await ethers.provider.getBlockNumber();
15+
16+
// Hardhat helper methods
17+
await ethers.getSigners();
18+
```
19+
20+
### Tests
21+
22+
Temporary solution to run manual tests until the V3 node is ready.
23+
24+
1. Start a node in Hardhat V2: `npx hardhat node`
25+
2. Run the tests: `pnpm test:tmp`
