Build trust

Origin, Verify, Folder, and Sign are the four primitives beneath every Bridge product. Compose them through one API to issue verifiable originals, prove authenticity, bundle documents, and capture binding signatures, in any application you build.

[the four things you command]

The digital Trust layer

Origin

Issue a verifiable original. Mint any document, an invoice, certificate, or bill of lading, as a unique, tamper-evident record with a known issuer and a provable history.

Verify

Prove authenticity in one call. Confirm a document is genuine, unaltered, and current, and read who issued it and when, without ever contacting the issuer.

Folder

Bundle and structure documents. Group related records into one referenceable set, with permissions, ordering, and a shared audit trail.

Origin

Issue a verifiable original. Mint any document, an invoice, certificate, or bill of lading, as a unique, tamper-evident record with a known issuer and a provable history.

The layer the platform runs on

The same four primitives power Express, Vault, Radar, and every Bridge product. Build your own, a registry, a verification flow, a document vault, on the exact infrastructure the platform is built from.

Built for builders

A clean REST API, typed SDKs, and a sandbox to ship against from day one.
