Maestro's vaults integrate with qualified custodians and curators to offer premium Bitcoin yield instruments on-chain.

## Shared platform properties

<CardGroup cols={2}>
  <Card title="Permissioned">
    Access is limited to qualified allocators and accredited investors. Eligibility requirements are vault specific.
  </Card>

  <Card title="Screened">
    Every deposit and withdrawal is screened for sanctions exposure and transaction risk before it settles, using TRM Labs.
  </Card>

  <Card title="Qualified curators">
    Every vault curator is extensively evaluated; today Maestro itself curates the live vaults.
  </Card>

  <Card title="Custody-ready">
    Each vault states its [custody options](/concepts/hybrid-custody) — direct deposit, a qualified custodian, or both.
  </Card>

## Vault configurations

Every vault's yield is **BTC-denominated**, but vaults come in different configurations depending on the strategy:

* **Fixed or variable yield** — Mezzamine Credit offers a fixed-income instrument, whereas other vaults track strategy performance (Bitcoin Solver).
* **Capped or uncapped allocation** — credit programs typically have capped capacity, whereas other vaults remain open.
* **Flexible or scheduled redemption** — rolling-window withdrawals, or fixed distribution dates across the term.
* **Receipt tokens** — transferable positions that trade on a secondary market: an exit route and price discovery independent of vault redemption.

<Info>
  A new curator or strategy can be added without changing how deposits, monitoring, and redemptions work — see [How it works](/get-started/how-it-works).
