New here? Start with the Discover tab, from Why TetraFi: it gives the full picture of what is possible and where each primitive applies before you pick an API.

​
What You’re Building On

Every institutional settlement carries three costs: principal risk, the gross settlement toll, and trapped liquidity. TetraFi runs one primitive against each. The three are composable - use one or all, each on the same shared liquidity and settlement network - and every deployment is modular, under full institutional control: your own immutable on-chain router, the venues, LPs, and jurisdictions it reaches, and how your compliance pipeline is composed. One compliance policy gates every layer. Own the deployment, share the network.

​
Each Primitive, One Level Deeper

Settlement rails
  • The invariant: funds move only on a signed order’s terms, through your own immutable router, into an escrow that releases against proof of delivery or refunds through a path nobody can pause.
  • What you integrate: quote, preflight, sign, submit. The preflight plan is the whole contract.
  • What never changes: custody stays on your side; an upgrade only ever adds a venue module.
Multilateral Netting (coming soon)
  • The invariant: your trade price is never touched. A run only decides who pays whom how much, by atomic multilateral set-off, with a validity proof checked on-chain first.
  • What you integrate: one extra choice per settlement - instant, or clear at a deadline you pick at a tighter price - plus a member surface for obligations, positions, runs, and notices.
  • What never changes: the residual settles on the rails, in your own policy domain, readable only inside your own slice.
Shared Collateral Network (coming soon)
  • The invariant: a draw is a priced exchange verified in the transaction that makes it, funding the fill or settlement leg itself, never a wallet, and encumbered only while live, only to that obligation.
  • What you integrate: draw, deposit, or curate.
  • What never changes: every draw re-runs your compliance policy; custody, routing, and obligation stay separate.
The rails are the pipes; netting and shared collateral are where the capital efficiency comes from. Every layer plugs into the same escrow and policy.
