## Kickstart Development

### Add Citrea to your Wallet / Code

For wallets, you can either use the information above, click & add using [**Chainlist**](https://chainlist.org/chain/4114)**,** or the following JSON as the baseline:

```json
{
  "chainId": "0x1012",
  "chainName": "Citrea Mainnet",
  "nativeCurrency": { "name": "cBTC", "symbol": "cBTC", "decimals": 18 },
  "rpcUrls": ["https://rpc.mainnet.citrea.xyz"],
  "blockExplorerUrls": ["https://explorer.mainnet.citrea.xyz"]
}
```

| Block Explorer URL | <p><a href="https://explorer.mainnet.citrea.xyz/"><https://explorer.mainnet.citrea.xyz/></a><br></p> |

### Get cBTC

cBTC is used as the native currency to cover gas, which is necessary to deploy smart contracts & use the network.

Head over to [Bridge Hub](https://citrea.xyz/bridge) to Bridge BTC from Bitcoin; USDC, USDT or WBTC from Ethereum.
