+
+## What is Epusdt?
+
+**Epusdt** (Easy Payment USDT) is a self-hosted **multi-chain, multi-token crypto payment gateway** built with Go. It started as a TRC20-only solution and evolved into a broader **multi-chain receiving platform**, allowing websites and applications to accept crypto payments across multiple networks and token types. No third-party custody, no platform fees — funds go directly into your wallet.
+
+> **GitHub Star 3000+** · **10+ supported platform integrations** · **Top real-world adoption among crypto payment tools**
+
+Deploy it privately, integrate with the HTTP API, and start receiving crypto payments in minutes.
+
+### Supported Networks and Tokens
+
+| Network | Tokens |
+|---------|--------|
+| **TRC20** (Tron) | USDT, TRX |
+| **ERC20** (Ethereum) | USDT, USDC, ETH |
+| **Solana** | USDT, USDC |
+| **BEP20** (BSC) | USDT, USDC, BNB |
+| **Polygon** | USDT, USDC |
+| **More** | Expanding continuously |
+
+> Actual support depends on the [latest release](https://github.com/GMWalletApp/epusdt/releases) and the [official docs](https://epusdt.com).
+
+---
+
+## Broad Compatibility, Plug and Play
+
+No matter what kind of platform you operate, Epusdt can fit into existing payment integration patterns with **minimal or no business logic refactor**, giving you a fast path to crypto payments for global use cases:
+
+| Category | Supported Systems |
+|----------|-------------------|
+| **AI Distribution** | [OneAPI](https://github.com/songquanpeng/one-api), [NewAPI](https://github.com/QuantumNous/new-api) |
+| **Card/Voucher Platforms** | [Dujiaoka](https://dujiao-next.com/), [ACG Faka](https://github.com/lizhipay/acg-faka) |
+| **Proxy Panels** | [V2Board](https://github.com/v2board/v2board), [XBoard](https://github.com/cedar2025/Xboard), [xiaoV2board](https://github.com/wyx2685/v2board/), [SSPanel](https://github.com/anankke/sspanel-uim) |
+| **Website Ecosystem** | [WordPress](https://wordpress.com/), [WHMCS](https://www.whmcs.com/) |
+| **Epay-Compatible Flow** | Works with platforms already using Epay-style payment interfaces |
+| **More** | Simple HTTP API, often integrated within 10 minutes |
+
+---
+
+## Core Features
+
+- **Multi-chain and multi-token** — TRC20, ERC20, BEP20, Polygon, and more
+- **Self-hosted** — full control of funds and wallet infrastructure
+- **Low-dependency runtime** — a single binary can run the service; low-traffic setups do not require MySQL + Redis
+- **Cross-platform** — supports x86 / ARM on Windows / Linux / Mac
+- **Multi-wallet rotation** — rotates receiving addresses to improve concurrency handling
+- **Async callback queue** — handles merchant notifications efficiently
+- **HTTP API** — easy integration from any language or framework
+- **Telegram Bot** — instant payment notifications and lightweight operations

+

+
+## How It Works
+
+Epusdt listens to supported blockchain APIs or RPC nodes across multiple networks such as TRC20, ERC20, BEP20, and Polygon. It captures incoming token transfers in real time and matches ownership using **amount differentiation** and **time-bounded locks**:
+
+```text
+Workflow:
+1. A customer initiates payment and needs to send 20.05 USDT
+2. The system searches for an available wallet-address + amount combination
+3. If address_1:20.05 is free -> lock it for 10 minutes and return it
+4. If already occupied -> add 0.0001 and try the next amount combination
+5. Background listeners keep watching wallet deposits and mark the order paid once the amount matches
+```
