# Treasury

The treasury is where platform fees (1.5% of successful sales) and the platform's 70% share of forfeited bonds accumulate.

## The address

Treasury authority: [`8n5xWEtc6p6xcphGLFFM3RAeXE5WQhXJg3aAPxk3bzDT`](https://solscan.io/account/8n5xWEtc6p6xcphGLFFM3RAeXE5WQhXJg3aAPxk3bzDT)

This is the platform's **Squads multisig vault** — the same multi-party custody that holds [upgrade authority](/security/upgrade-authority.md), so moving treasury funds requires the same multi-party approval as changing program code. Fee flows are publicly traceable on-chain.

## How it's constrained

* The fee destination is validated **inside the programs** by an owner check against the compiled-in treasury authority. A settlement cannot route fees anywhere else — not even via the backend's own hot key.
* The treasury authority **never signs marketplace transactions**. It exists as the ownership check for the fee destination account; day-to-day operation of the marketplace never touches it.
