02 — Core Technical Hypothesis

Non-Invasive Message Enrichment.

Real-time payment routing requires a parallel maturity in operational verification. Soliidus is researching the feasibility of using standard ISO 20022 extension pathways — specifically the <SplmtryData> element within pacs.008 payloads — to transport lightweight integrity metadata. The objective is to assist participating institutions in automating evidence for risk-reconciliation frameworks without disrupting core clearing and settlement mechanics.

03 — Research & Validation Framework

Empirical Sandbox Simulation.

TRL 3–4 Research Stage

Our architecture is currently positioned at Technology Readiness Level 3–4, with core verification logic validated on synthetic datasets. Soliidus is developing a non-live, pre-production simulation environment to test verification logic, establish empirical safety baselines for distributed integrity validation, and validate architectural assumptions before any live deployment models are considered.
