+The [Blackberry testnet](https://raas.gelato.network/rollups/details/public/polygon-blackberry) is a zero-knowledge-powered, layer 2 testnet based on Sepolia. It uses Polygon CDK for transaction validity while keeping transaction data off-chain using [DACs](../glossary/index.md#data-availability-committee-dac).

+- Add the RPC network details to your wallet by navigating to the add network input and entering the data as given in the table below.
+- Obtain Sepolia ETH from the public faucets available.
