-# Run the development node
-dev-node run
+# Run geth in development mode (default port 8545)

-To test contracts with Geth
+Alternatively, you can run geth with mitmproxy in a tmux window:
 
 ```sh
 # Run geth with mitmproxy in a tmux window
 geth_stack
 ```
 
+This will start a local Geth development node with HTTP RPC enabled, useful for comparing behavior between Revive and standard EVM environments.
+
+## Recording and Replaying RPC Requests
+
+### Recording RPC Requests
+
+When testing and debugging, you can record all `eth_sendRawTransaction` requests using the `--record` flag:
+
+```sh
+# Record requests when running eth-rpc
+eth-rpc run ws://localhost:9944 --record
+```
+
+When `--record` is enabled, eth-rpc will:
+
+- Log all output to console and `/tmp/eth-rpc.log`
+- Extract and save all `eth_sendRawTransaction` requests to `/tmp/eth-rpc-requests.log`
+
+### Replaying Recorded Requests
+
+You can replay recorded requests using the `scripts/run-all.sh` script:
+
+```sh
+# Replay all recorded requests against localhost:8545
+./scripts/run-all.sh
+```
+
+This script will:
+
+- Send each recorded transaction to the RPC endpoint
+- Wait for transaction receipts
+- Display status (✓ for success, ✗ for failure)
+- Report any errors or failed transactions at the end
+
+This is useful for regression testing - record a successful test session, then replay it against new builds to ensure compatibility.
