LayerZero and 21X AG reported on 4 November that a month-long technical pilot processed 10,000 order matches per second with 21X’s central limit order book running on a private-permissioned deployment of Zero. The companies compared performance with an EVM-based benchmark and described an improvement of up to 45 times. Both numbers relate to the tested configuration, not an audited record of publicly accessible exchange executions.[1]
21X already operates a European trading and settlement venue under the EU DLT Pilot Regime. The new point is the trial of its matching design on another architecture, not an announcement that the existing 21X production service has moved entirely onto Zero. The companies say the pilot maintained order matching onchain without relying on an offchain matching engine, and settled the matched activity in the same transaction.[1]
A central limit order book must preserve reliable sequence, matching rules and state under heavy order flow. Keeping matching and settlement onchain can reduce some reconciliation steps, but it also exposes throughput, privacy, transaction finality and governance requirements. The pilot took place on a private-permissioned instance, allowing controlled participants and data visibility; these conditions are materially different from an unrestricted public blockchain.[1]
What the technical pilot actually measured
| Measure or condition | Verified scope |
|---|---|
| Pilot duration | One month |
| Deployment | Private-permissioned Zero instance |
| Matching architecture | Onchain central limit order book |
| Reported throughput | 10,000 order matches per second |
| Reported comparison | Up to 45× selected EVM baseline |
| Not demonstrated | Live market turnover, independent latency audit or universal broker access |
The 10,000 matches-per-second figure refers to a vendor-reported maximum throughput in a private-permissioned trial that ran for a month. It cannot be multiplied by all trading hours to produce a claim about executed market turnover, and it does not establish spreads, price formation, broker participation or settlement failure rates in a live regulated market. The up-to-45-times comparison also depends on the particular baseline chosen.[1]
For broker and exchange technology teams, the useful implication is architectural: EVM compatibility might permit existing software tooling while changing the capacity available for regulated instruments. But integration still involves order controls, identity permissions, transaction sequencing, corporate actions, custody and disaster-recovery arrangements. A fast matching engine alone does not make the rest of the trading lifecycle institution-ready.[1]
The announcement explicitly differentiates 21X’s European operation from its US affiliate, which is not a registered US broker-dealer. The completed event is a joint technical pilot; commercial deployment, product authorisations and measured operating quality remain separate milestones.[1]
