# Sdks libraries

> Choose the right JavaScript and Solidity tooling for building on TeQoin

# SDKs and libraries

TeQoin is EVM-compatible, so you can use standard Ethereum tooling instead of waiting for chain-specific packages.

## Recommended stack

### Smart contracts

* `solc` for compilation
* OpenZeppelin Contracts for audited building blocks
* Hardhat or Foundry for development and deployment

### Frontend and backend apps

* `ethers` for contract calls and transactions
* `viem` for typed client utilities
* `wagmi` for React wallet state and hooks

## Install examples

### Hardhat

```bash theme={null}
npm install --save-dev hardhat @nomicfoundation/hardhat-toolbox dotenv
```

### Foundry

```bash theme={null}
curl -L https://foundry.paradigm.xyz | bash
foundryup
```

### Frontend libraries

```bash theme={null}
npm install ethers
npm install viem wagmi @tanstack/react-query
```

## Picking a stack

Use this rule of thumb:

| Need                         | Best fit     |
| ---------------------------- | ------------ |
| Fastest contract iteration   | Foundry      |
| Familiar JavaScript workflow | Hardhat      |
| Small frontend app           | ethers       |
| React production app         | wagmi + viem |

## Network configuration snippet

```javascript theme={null}
export const teqoin = {
  id: 420377,
  name: 'TeQoin L2',
  network: 'teqoin',
  nativeCurrency: {
    name: 'Ether',
    symbol: 'ETH',
    decimals: 18,
  },
  rpcUrls: {
    default: {
      http: ['https://rpc.teqoin.io'],
    },
  },
};
```

## Good defaults for new teams

If you are starting from scratch:

1. Use Foundry for contracts.
2. Use React + Vite for the frontend.
3. Use ethers for the first integration.
4. Add Wagmi only when you need richer wallet UX.
