# \`jsonParsed\` Support

{% hint style="success" %}

### Optional Feature

If you don't need `jsonParsed` support, you do not need to complete any of the following steps!
{% endhint %}

Old Faithful is written primarily in Golang. Because Solana is written in Rust, the most optimal way for Old Faithful to parse transactions into a JSON format is to rely on the official Solana SDK's for parsing. 

Because of this, the compilation step of Old Faithful requires an additional step to enable `jsonParsed` support.

### Requirements

* Install Golang >1.20

### Compiling

After building the `faithful-cli` binary, run this command in the same folder:

```
make jsonparsed-linux
```

You can use this binary to use Old Faithful identical as before, with the added `jsonParsed` feature.
