What makes it different
Single identical payment gate that works across ten different web stacks without requiring accounts or API keys
100% of payments go directly to site owners' wallets with no custody or intermediaries
Runs by one person with nineteen live paid services and no outside capital
All services self-serve and automated by design with on-chain settlement
Runs entirely locally in your process with no network calls or telemetry
Encryption at rest built into the open-source engine itself, not an enterprise add-on
Significantly faster vector search than hnswlib with graph-indexed vertex retrieval
Signed provenance and verified audit trail using C2PA, COSE and SCITT standards
Embedded library model eliminates dependency on external services or vendor lock-in
