GENERAL DESCRIPTION
-----------------------------------------------------------
This system is a complete "Self-Hosted" cryptocurrency payment gateway solution, designed to operate autonomously without relying on third parties or intermediaries. It allows any business or individual to process cryptocurrency payments directly into their own wallets, maintaining absolute control of funds (Non-Custodial).
The system acts as your own bank payment processor but for the blockchain world, supporting multiple networks and tokens with advanced capabilities for automatic conversion and fund consolidation.
KEY FEATURES
-----------------------------------------------------------
1. MULTI-CHAIN SUPPORT
The system is designed to operate simultaneously on the most important blockchains in the market, both EVM-based networks (Ethereum Virtual Machine) and native Bitcoin.
2. UNLIMITED TOKEN MANAGEMENT
- Native support to add ANY ERC20 token from supported networks.
- Dynamic configuration: You can add popular tokens (USDT, USDC, DAI) or custom tokens from your own projects.
- Automatic detection of decimals and contracts.
3. HD WALLETS AND NON-CUSTODIAL SECURITY
- Uses Hierarchical Deterministic Wallet technology (HD Wallets).
- Generates a unique and exclusive address for each payment order (BIP44/BIP84).
- The system owner possesses the "Master Seed" (Mnemonic). The software never retains funds; they are always under the cryptographic control of the administrator.
4. INTELLIGENT SWEEPING (FUND CONSOLIDATION)
- Automated system that detects received payments and automatically moves (sweeps) them to the administrator's cold or main wallet.
- Constant monitoring of the Mempool and block confirmations.
5. AUTOMATIC GAS MANAGEMENT (GAS PUMP)
- Solves the common problem of token payments: If a customer pays with USDT but does not have ETH/BNB for the gas fee, the system automatically injects the exact amount of gas needed from an operating wallet to ensure funds can be moved to the main wallet.
6. HYBRID AUTO-SWAP TO STABLECOIN (USDT)
Integrated volatility protection. The system can automatically convert received payments in volatile cryptocurrencies to USDT before sending them to the final wallet.
- For EVM Networks (Ethereum, BSC, etc.): Uses direct integration with DEXs (Decentralized Exchanges) like Uniswap, PancakeSwap, Trader Joe, etc., to perform the swap in a decentralized manner and at the best market price.
- For Bitcoin (BTC): Features an integrated native system that allows automatic conversion of payments received in Bitcoin directly to USDT, facilitating settlement in stablecoin.
SUPPORTED NETWORKS
-----------------------------------------------------------
The system is designed with an EVM-agnostic architecture, allowing it to support the vast majority of blockchains compatible with the Ethereum Virtual Machine.
1. Bitcoin (BTC)
- Full native support with SegWit addresses (Bech32/bc1) for cost optimization.
2. EVM Networks (Ethereum Virtual Machine)
- Universal Compatibility: Supports practically any EVM-compatible network (Layer 1, Layer 2, Sidechains) simply by configuring its RPC URL.
- Requirements: The node/RPC must support standard JSON-RPC methods (eth_getBalance, eth_sendRawTransaction, eth_blockNumber, etc.).
Examples of supported and tested networks:
- Ethereum (Mainnet)
- BNB Smart Chain (BSC)
- Polygon (MATIC)
- Arbitrum One
- Optimism
- Avalanche (C-Chain)
- Base, Cronos, Fantom, zkSync, etc.
TECHNICAL SPECIFICATIONS AND ADVANTAGES
-----------------------------------------------------------
A. PRIVACY AND CONTROL
- No KYC (Know Your Customer): Being self-hosted software, it does not require identity validation to operate.
- No Blocks: No one can freeze your funds, as the private keys are in your possession.
B. USER EXPERIENCE (CHECKOUT)
- Professional and responsive payment page (Checkout).
- Real-time payment detection via WebSockets (no page reload needed).
- Dynamic QR codes to facilitate payment from mobile devices.
- Real-time exchange rate calculator (Fiat to Crypto).
C. PERFORMANCE
- Built on Node.js and Fastify for maximum speed and low latency.
- Uses Redis for high-performance caching and session management.
- Optimized SQL database for historical transaction records.
D. ADMIN PANEL
- Complete dashboard to view transactions, volumes, and statuses.
- Visual configuration of networks, tokens, and commissions.
- History of "Sweeps" and conversions.
E. INTEGRATION AND API (DEVELOPER FRIENDLY)
Designed to be easily integrated into any website, e-commerce, or application.
- Full RESTful API:
1. Get Networks and Tokens: Public endpoint to dynamically list which cryptocurrencies the merchant accepts.
2. Create Order: Programmatic generation of payment links from your backend.
3. Check Status: Verification of the status of any order (pending, paid, expired).
- Webhooks (Real-Time Notifications):
The system sends automatic POST notifications to your server (callback URL) whenever a payment status changes (e.g., from "pending" to "completed"), allowing automation of product or service delivery without manual intervention.
F. BUSINESS MODEL AND PROFITABILITY
The system operates as a Multi-User platform (SaaS), allowing the owner to act as a payment service provider for third parties.
1. Operation Flow:
- Users (merchants, stores) register and generate payment orders to charge their final customers.
- The system processes and validates payments on the blockchain.
2. Monetization for the Administrator:
- The platform owner earns money through Withdrawal Commissions.
- From the Admin Panel, a global commission percentage is configured (e.g., 1%, 2%, 5%).
- When a user requests to withdraw their accumulated earnings to their external wallet, the system automatically deducts this commission, generating passive income for the administrator.
3. Gas Cost Recovery (Network Fees):
- The system automatically calculates the estimated gas cost (network fee) required to move the funds and transparently includes it in the total amount to be paid by the final customer.
- This ensures that the Administrator always recovers the gas expense incurred during the "sweeping" (token sweeping) process, protecting the business profitability.
IDEAL USE CASES
-----------------------------------------------------------
- E-commerce wishing to avoid 1% - 3% fees from external gateways.
- High-Risk businesses suffering from blocks in traditional gateways.
- Crypto Projects wishing to charge in their own native Token.
- Sale of Digital Services with immediate settlement and without borders.
