💳 Argon – Multi-Chain Payment Gateway (Proof of Concept)

Argon is a payment gateway prototype built as a personal project to test and sharpen my backend development skills.
It integrates with multiple blockchains — AirDAO, Solana, BEP20 (BSC), and TON — to process transactions in a unified way.

Unlike production-ready systems, Argon does not use an external database.
Instead, all data is saved locally in JSON files, keeping the project lightweight and focused on demonstrating the core logic.
