 ### 📌 **Tasks**:
 
-- Create a [metamask](https://metamask.io/) account and fund it with some Goerli ETH.
-  - You can use the [faucet](https://goerlifaucet.com/) to get some Goerli ETH.

+  - The faucet now want you to have real ETH to counter bots so just ask PoC team to send you some.

+> You can now broadcast transactions to the Sepolia testnet, by the endpoint listed on the [chain page](https://sepolia.dev/) like this one `https://rpc.sepolia.org/`.
 
 - Now deploy and interact with your contract, like you did in the previous steps, but this time on the Goerli testnet.
 > Don't forget to use your endpoint, shutdown your local blockchain to be sure you are using the Goerli testnet.
