+## Transaction Sender
+
+The builder includes a `transaction-sender` for sending miniscule transactions for the purpose of testing the rollup block construction process. The `transaction-sender` is located in `bin/submit-transaction.rs`.
+
+It requires a key to sign the transactions and a funded wallet.
+
+### Environment Variables 
+
+The `transaction-sender` also has a set of configurable environment variables listed below.
+
+```
+RPC_URL="" # The URL of the RPC endpoint of the node you're sending the transaction to.
+RECIPIENT_ADDRESS="" # The address the submitter addresses the transaction to.
+SLEEP_TIME="" # The time to wait before sending another transaction, in seconds.
+SIGNER_CHAIN_ID=""
+SIGNER_KEY="" #
