@xapps-platform/publisher-verifier

Verification helper library for backend publisher callback/executor flows.

Install

npm install @xapps-platform/publisher-verifier

When to use it

Use this package directly when a backend needs publisher-side proof verification helpers without taking a dependency on the broader @xapps-platform/server-sdk surface.

Status

This package is now prepared for public distribution because it complements external executor/callback verification flows built on top of @xapps-platform/server-sdk.

Exports

• Main entry: @xapps-platform/publisher-verifier (src/index.js)
• Includes JWS and WebAuthn verification helpers used by server-side validation flows.

Minimal usage

import {
  verifyJwsSubjectProof,
  verifyWebauthnSubjectProof,
  verifySubjectProofEnvelope,
} from "@xapps-platform/publisher-verifier";

const jwsResult = await verifyJwsSubjectProof(input);
const webauthnResult = await verifyWebauthnSubjectProof(input);
const envelopeResult = await verifySubjectProofEnvelope(input);

Notes

• Runtime: Node.js backend.
• Complements @xapps-platform/server-sdk verification/callback primitives.
• See package/runtime ownership: docs/guides/12-package-usage-and-ownership.md.
