Ed25519 Signing

Every asset is signed with Ed25519 elliptic curve cryptography, ensuring non-repudiation and global verifiability without a central authority.

Immutable Anchor

Provenance data is hashed and anchored on the Polygon network, providing a permanent, tamper-proof record of every scan and transaction.

High-Throughput API

Our edge-optimized API handles 50,000+ requests per second, designed for massive retail events and global supply chain integrations.

Built For Engineers.
Scaled For Giants.

Low-Latency SDKs

Native support for Node.js, Go, Rust, and Python.

Webhooks & Automation

Trigger custom logic on scan, verification, or revocation events.
