It lets merchants accept USDT (TRC‑20) without ever exposing private keys, using a watch‑only server and a local signer. The server manages invoices, watches Tron blocks, and sends signed webhooks, while all signing happens on the operator’s machine via a CLI. Designed for developers and businesses needing a trust‑minimized payment gateway, it eliminates custodial fees and central points of failure. Its strict separation of signing and API layers provides strong security guarantees over typical hosted solutions.
