v1.2.0 - Universal agent compatibility

What's new in v1.2.0

Universal Agent Compatibility

• All discovery endpoints now surface complete protocol support: MCP, ACP, x402, MX-8004, OpenAI Plugin, LangChain, CrewAI
• OpenClaw skill reference included in all manifests
• x402/openx402 compatibility explicitly documented

Improvements

• Logo upgraded to high-resolution icon (512x512)
• All metadata endpoints bumped to v1.2.0 for consistency
• Added repository links (main, action, openclaw-skill) across all discovery files
• Pricing now reflects dual payment methods: EGLD (MultiversX) + USDC (Base via x402)

Links

• GitHub Marketplace: https://github.com/marketplace/actions/xproof-certify
• OpenClaw skill: https://github.com/jasonxkensei/xproof-openclaw-skill
• Main repo: https://github.com/jasonxkensei/xProof
• Live service: https://xproof.app

v1.1.1 - Positioning coherence & AI agents branding

What's changed :

Positioning alignment

• Updated description field to reflect canonical positioning: "Proof primitive for AI agents and humans on MultiversX"
• Fixed GitHub Marketplace rendering issue where & was stripped — now uses and for reliable display

Why this matters
This is a branding-only update. No functional changes.
Ensures the Marketplace sidebar, action metadata, and all discovery surfaces consistently identify xProof as a proof primitive for AI agents and humans.

Full Changelog: v1.1.0...v1.1.1

xProof Action v1.1.0 - Operable trust primitive

xProof Action v1.1.0 — Operable trust primitive

This release marks xProof's transition from certification tool to operable infrastructure primitive for AI agents & humans on MultiversX.

Security

Webhook HMAC signing with timestamp-based replay protection (asymmetric window)
Timing-safe signature verification
API key rotation with 24h grace period
IPv6-safe rate limiting across all endpoints
Observability

Structured JSON logging with end-to-end requestId correlation
Blockchain latency monitoring with rolling percentiles (p50/p95/p99)
Configurable alerting on transaction queue failures (threshold + cooldown)
Health endpoint with operational metrics
Architecture

Persistent transaction queue (PostgreSQL-backed, exponential backoff retry)
MX-8004 compliant validation flow
Centralized RBAC middleware
Agent-ready, API-first design
xProof is now an operable trust primitive on MultiversX, suitable for CI/CD artifact anchoring and agent output certification.

xProof – Cryptographic File Proof for GitHub Actions

xProof Notarize Action v1.0.0

Generate verifiable, immutable proof for your build artifacts directly from your CI/CD workflow.

Initial Stable Release - Ready for production use! 🚀

What's New

This GitHub Action enables seamless notarization of build artifacts on the MultiversX blockchain via xProof, creating immutable proof-of-existence for any file.

Key Features

✅ Automated Notarization - Notarize multiple files in a single workflow step
✅ Glob Pattern Support - Use wildcards to notarize entire directories (e.g., dist/**/*.js)
✅ Rich Outputs - Get proof IDs, verification URLs, and SVG badges for documentation
✅ Error Handling - Gracefully handles missing files and API failures
✅ GitHub Step Summary - Beautiful markdown tables in your workflow summary
✅ Flexible Configuration - Optional author names and custom API URLs
