 Now, we can use the generated bindings to build a transaction using our protocol.
 
 First access to the `gen/rust` folder

-We need to open `lib.rs` and update the TRP endpoint to point to the correct URL (unless you have it configured on trix.toml). The default value is `http://localhost:3000/trp`, but if you're using different port or endpoint, make sure to update it.
+We need to open `lib.rs` and update the TRP endpoint to point to the correct URL (unless you have it configured in `trix.toml`). For the local devnet the TRP endpoint is available at `http://localhost:8164/`. If you're using a different port or network, update this value accordingly or set it in `trix.toml`.
 
 For the following example, we will use the main.tx3 file generated by trix.
 
-Now, we can create a new file called `src/bin/test.rs` in the same folder (or any other folder) and add the following code:
+Before running the example below, start the local devnet in a separate terminal with:
+
+```
+trix devnet
+```
+
+The devnet will start and print timestamped INFO logs that show the Devnet components starting, running, and stopping.
+While the emulator is starting you should see startup messages and the tool prints sample wallets and addresses.
+
+If you don’t see addresses in the console or if you need to look up the addresses for a specific named wallet (for example a wallet defined in `trix.toml`), you can run:
+
+```bash
+trix wallet <name>
+# e.g. trix wallet alice
+```
+
+This command returns a small JSON structure that includes the `testnet` address you should use in examples. Example output:
+
+```json
+{
+    "name": "alice",
+    "public_key": "9b1622919b3a74c037599d67d065f10c46c047801efe024a80344e79be4d9c0b2edb662977726943b63e8c9c5ee761c77f682ee31ef28e74fcab8a54bf692438",

+    }
+}
+```
+
+Use the `testnet` address value as the sender/receiver address in the Rust example.
+
+Now, create a new file called `src/bin/test.rs` inside the generated crate (for example: `gen/rust/src/bin/test.rs`) so that Cargo can find and run it. Add the following code (replace the placeholder addresses with the ones obtained via `trix wallet`):
 
 ```rust
 use tx3_sdk::trp::args::ArgValue;

 **NOTE**: Replace `trix_example` with the name of your protocol.
 
 To your Cargo.toml file, add the following dependencies:
+
 ```toml
 tokio = { version = "1", features = ["full"] }
 ```
 
 Finally, we can run the test file to build a transaction using our protocol:
+
 ```bash
 cargo run --bin test
 ```
