This is a status note rather than an announcement. It records what the Settlement Computer is today, on a dedicated testnet, and what remains in design. Detailed technical documentation is available to qualified institutions under NDA.

Five products exercised on testnet

Five products run on one settlement chain, a dedicated Avalanche L1 with settlement logic implemented as native precompiles rather than smart contracts. Settlement computes multilateral net positions across corridor participants. PayNet aggregates high-volume, small-value flows into netting-eligible institutional obligations. RiskNet scores counterparty, corridor and systemic risk before an obligation enters a netting window, with admission control applied at the protocol level. AssetNet nets paired delivery-versus-payment legs for tokenised financial assets. StableNet nets heterogeneous stablecoin obligations with peg verification before netting.

All five share one netting engine, one compliance gate, one settlement state machine and one validator set. Settlement instructions are generated natively in ISO 20022 CBPR+ (pacs.008 and pacs.009 at the settlement layer, with pain.001, pacs.002, camt.053 and camt.054 via the institutional API). Privacy is cryptographic rather than hardware-based, with tiered supervisory view keys; the runtime is Qedis, owned by Digitalyze Labs Ltd and perpetually licensed to the NETTA group.

All figures are from the Lagrange testnet on generated test flow, as at September 2026. Participant profiles are synthetic. No production traffic. Multilateral compression reaches up to 95% on testnet; the realised figure depends on corridor and flow mix, and directional corridors compress materially less.

Just-in-time atomic counter-attestation

The settlement model is what the home page calls just-in-time atomic counter-attestation. Multilateral net positions execute atomically at window close against counter-attested standing instructions held with each participant's settlement bank. The residual net settles just in time; pre-positioned liquidity on outbound legs is eliminated where the rail permits just-in-time funding and materially reduced where it does not, and NETTA never holds funds or acts as counterparty at any point.

Three domains in design

Three further settlement domains are in design and are not running: maturity-aware netting for trade finance, time-indexed netting for energy settlement, and clearing for autonomous economic agents. They share the same chain and the same netting engine. Nothing about them should be read as available.

Intellectual property

Twenty US provisional patent applications are on file: sixteen held by FiatRails Foundation Ltd, covering multilateral settlement determination, counter-attested just-in-time settlement, risk intelligence and micro-obligation aggregation, tokenised-asset and digital-currency netting, Sharia-compatible settlement architecture and cryptographic privacy; and four covering the Qedis privacy and post-quantum runtime, owned by Digitalyze Labs Ltd and licensed perpetually to the group.

Where this sits with regulators

NETTA is a technology service provider outside the licensable perimeter; all licensable activity remains with participating institutions. The protocol has been self-assessed against all 24 CPMI-IOSCO Principles for Financial Market Infrastructures. Regulatory dialogue is documented in the UAE, Singapore, the UK and the EU. Production use will follow controlled pilots under the supervisory engagement appropriate to each jurisdiction.

What comes next

Controlled pilots with banks, payment institutions and market infrastructures in 2026 to 2027. Institutions that want the technical documentation, the PFMI self-assessment and the compliance materials can request a briefing; an NDA is available to qualified participants.

Nothing in this note is an offer, a solicitation or advice. Testnet figures are not production performance. No institution named or implied here is a customer or partner of NETTA.
