 - **`sender=sender`**: We use the EOA we created earlier, which already has the necessary information to sign the transaction and contains the correct `nonce`. The `nonce` is a protection mechanism to prevent replay attacks - it must equal the number of transactions sent from the sender's address, starting from zero. The framework automatically manages nonce incrementing for us.
