Security

Built to fail safe.

Privacy is the product. Security is what makes it real. Below is how XMRgate is built — the controls, the infrastructure, and how to report an issue.

Six pillars

Hashed API keys

Keys are stored as bcrypt hashes. We cannot recover a plaintext key — even with full database access. Lost a key? Revoke and rotate.

HMAC-signed webhooks

Every webhook payload is signed with HMAC-SHA256. Verify the signature before fulfilling an order. Sample code is in every SDK.

Rate limiting per key

Default 100 req/min per API key, scoped independently. Abuse on one key never starves the others.

Private Docker network

Internal services (Postgres, Redis, blockchain nodes) live on a private Docker network. None of them are exposed to the public internet.

Encrypted wallet operations

Platform wallets are operated through locked-down workers. Admin dashboards show addresses and status, not plaintext seed phrases or wallet passwords.

Scoped keys

Create read-only keys for analytics tools and full-access keys for your backend. Each key shows its last-used timestamp.

Infrastructure

EU jurisdiction, minimal surface area, no third-party analytics.

Hosting
Hetzner — Helsinki / Falkenstein
Edge
Cloudflare DDoS + WAF (clearnet)
TLS
Let's Encrypt, TLS 1.3 only
Database
PostgreSQL · daily encrypted backups · 14-day retention
Job queue
Redis + BullMQ for webhook delivery
Tor mirror
Hidden service v3 .onion endpoint

Responsible disclosure

Found a vulnerability? Report it to security@xmrgate.com (PGP key on the contact page). We do not pursue good-faith researchers.

  • Use a secure, throwaway email for the report
  • Include a clear proof of concept where possible
  • Allow 90 days for remediation before public disclosure
  • Do not access merchant data beyond what is needed to demonstrate the issue

Out of scope

  • · Volumetric DDoS, brute force, or rate-limit testing
  • · Reports about missing security headers without impact
  • · Self-XSS in third-party password managers
  • · Findings in dependencies without a working exploit

We acknowledge reports within 72 hours.
