Settlement Engine

Atomic delivery-versus-payment across networks.

Developer docs

What it does

The Settlement Engine is the core of SBX AURA. It settles transactions atomically, so both legs complete together or neither does, removing the risk that sits between delivery and payment. It screens compliance before settlement, and through zero-knowledge proofs can settle confidentially, letting two institutions complete a transaction without revealing their holdings.

How it works

The Settlement Engine is the core of SBX AURA. It works with Payment Rails for the money leg, Cross-Chain Transfer to reach other networks, and the Compliance Engine to screen every transaction before it settles.
