# Welcome

Welcome to the official **Fintag** documentation.

Fintag is an identity-first crypto payments and token infrastructure that lets users and developers move value using human‑readable handles instead of wallet addresses. \
\
Our mission is simple: **replace wallet addresses with identity and bring crypto natively into social communication.**

On the infrastructure side, Fintag provides APIs and SDKs that enable developers to integrate identity‑based payments, token transfers, swaps, and on‑chain interactions into their own products.
