# TetraFi T+0 Vaults

> One primitive that turns delayed settlement into instant settlement - coming soon.

<Note>
  **Coming soon.** T+0 Vaults are in design, not yet live. These pages describe the planned protocol so issuers, capital providers, and market makers can evaluate it early - specifics such as parameters and contract addresses publish at launch.
</Note>

## The Settlement-Time Gap

A token burns in seconds; the value behind it often doesn't. Underlyings liquidate on T+1 cycles or worse - redemption windows, withdrawal queues, out-of-hours cutoffs - so "instant redemption" promises break precisely when they're tested. Today every product spanning that gap patches it privately: idle buffers, solver balance sheets, perpetual incentive spend.

T+0 Vaults are the shared answer - **one primitive that bridges TradFi's asynchronous, delayed settlement cycles with on-chain instant settlement**, built as open network infrastructure rather than a per-product fix.

## What a T+0 Vault Is

A compliance-gated pool of committed capital connecting passive institutional deposits to high-frequency settlement demand. The vault fronts the fast leg of a trade - the instant redemption, the T+0 settlement, the cross-chain fill - and recycles its capital when the slow leg completes.

The mechanism is deliberately **not lending**. Vault capital moves only inside a transaction where an obligation worth more at oracle price arrives in exchange: a tokenised asset awaiting redemption, a T+1 settlement receivable, a claim on escrowed funds. There is no borrower who can run off with the money - only an asset the vault bought at a discount, and that discount is the depositor's yield.

| **Deployment**     | Curated vaults at launch, opening to independent curators over time                                              |
| **First customer** | TetraFi itself - its settlement rails originate the first obligations the vaults buy                             |
