USDT & USDC payments, without custody.
Open Mine Payments is a self-hosted stablecoin payment processor. It watches Tron, Ethereum, BSC, Polygon, and Avalanche for inbound USDT and USDC, confirms them, and notifies your application — all driven by an extended-public-key (xpub). Private keys never leave the operator's hardware wallet.
Non-custodial
The service holds only public keys (xpubs). Sweep funds from your hardware wallet at your own cadence.
HMAC webhooks
Signed event delivery with at-least-once semantics, retries, and a dashboard for failed deliveries.
Operator dashboard
Real-time chain health, invoice state, deposits matrix, audit log, API-key & webhook management.
API-first
Documented OpenAPI 3.1 contract. Idempotent invoice creation with Idempotency-Key.

For partners
Open Mine Payments is proprietary software built by and for Open Mine. We're evaluating licensing it to other operators who need self-hosted, xpub-only stablecoin processing without surrendering custody.
