+Developers can also use RPC providers to trace transactions and utilize `debug_traceTransaction` on live networks with the `stylusTracer`. For example:
+
+```
+curl -s -X POST -H "Content-Type: application/json" --data '{
+  "jsonrpc": "2.0",
+  "method": "debug_traceTransaction",
+  "params": ["<YOUR_TXN_HASH>", {"tracer": "stylusTracer"}],
+  "id": 1
+}' <YOUR_RPC_URL>
+```
+
+You can use the Sepolia RPC URL from our our [list](https://docs.arbitrum.io/for-devs/dev-tools-and-resources/chain-info#arbitrum-public-rpc-endpoints) or use an external provider, some that support this are:
