Coldtill
Coldtill is self-hosted software for merchants and developers who want to accept cryptocurrency payments on infrastructure they control.

Customers can pay using supported coins and networks, with optional conversion through NEAR Intents to USDC or USDT. The product includes a merchant dashboard, REST API, signed webhooks, OpenAPI documentation, a TypeScript SDK and a WooCommerce plugin.
