# Tracing Transactions

> How to trace transactions on your Conduit chain using Foundry's Cast tool and the openchain.xyz API.

#### Install Foundry

Install [Foundry](https://github.com/foundry-rs/foundry).

#### Submit signatures via openchain.xyz

Submit your signatures through the [openchain.xyz](http://openchain.xyz) API. Trace methods require an API key starting August 4, 2026 — append your key to the RPC URL.

```bash
cast run --rpc-url=[your_rpc_url]/[your_api_key] [tx_hash]
```
