> [!WARNING]
>
> The Celo Sepolia Testnet is designed for testing and experimentation by developers. Its tokens hold no real world economic value. The testnet software will be upgraded on a regular basis. This will erase your accounts, their balance and your transaction history. You may encounter bugs and limitations with the software and documentation.
