necko3

Self-hosted, non-custodial Web3 payment gateway API for accepting crypto payments.

Servicefree

necko3 is a self-hosted, non-custodial crypto payment gateway that businesses or developers can run themselves to accept EVM-chain payments, such as USDC. It derives a unique deposit address per invoice from a single wallet key without ever storing private keys, tracks payments in real time through confirmations and blockchain reorgs, and sends a signed webhook once a payment is confirmed. It ships as a Docker-ready API server with a REST API and interactive Swagger documentation.
