# prism decode

> Decode a transaction failure and identify the root cause.

The `decode` command is the entry point for most debugging sessions. It provides Tier 1 diagnostics.

## Usage

```bash theme={null}
prism decode <TX_HASH> [FLAGS]
```

## Flags

| Flag            | Description                                                                  |
| --------------- | ---------------------------------------------------------------------------- |
| `--network`     | Specify the network (`mainnet`, `testnet`, `futurenet`). Default: `testnet`. |
| `--rpc-url`     | Use a custom Soroban RPC endpoint.                                           |
| `--raw`         | Decode a raw error string from logs instead of a transaction hash.           |
| `--output json` | Output the diagnostic report in JSON format.                                 |
