Orbitra L1 · Market services layer

The layer that makes Orbitra L1 market-native.

ApexMatch lives in the market-services layer of Orbitra L1, alongside Aegis, Prism, clearing and settlement. It is part of the protocol rather than a contract deployed on top of it — the property that makes Orbitra L1 a market-native Layer 1.

Illustration: Orbitra L1 as six stacked layers: experience at the top, then market services, execution, consensus, data and network at the base. Light travels down through the layers as a transaction is executed and finalized, and back up as confirmed state.

Role in the Orbitra L1 stack

Orders arrive from the experience layer — Orbitra Prime, institutional APIs, wallets and applications — already signed. ApexMatch sequences them, consults Aegis and Prism within the same layer, matches them and produces clearing deltas.

Those deltas are not handed to a separate settlement system. They become transitions that the execution layer runs on VectorLanes and that QSE finalizes, so a fill and its settlement are one event rather than two records waiting to be reconciled.

Because matching is a native module, contracts on NexusWASM reach it through typed calls. Every application on the network shares the same books instead of fragmenting liquidity across separate copies.

Illustration: A signed order travels left to right through six stages: ingress, fair sequencing, the Aegis risk gate, price-time matching, clearing into net deltas and finalization with a QSE proof. A trace of signed evidence records each stage.

What ApexMatch contributes to the network

  • 01

    Order books as protocol services

    Central limit order books, RFQ and block workflows serve Orbitra Prime and network applications through the same primitives.

  • 02

    Risk in the same layer

    Aegis pre-risk runs beside matching, so an order that would breach a limit is rejected before it reaches the book.

  • 03

    Reference data within reach

    Prism market state sets price bands and pause conditions for each market without leaving the layer.

  • 04

    Settlement as a transition

    Clearing deltas flow directly into execution and finality, with no batch reconciliation between venue and ledger.
