Technical Architecture

Smart Contract Design

EvoPay’s core infrastructure is built on Ethereum using modular, non-custodial smart contracts. These contracts govern payment flows, wallet logic, and future integrations like fundraising and lending — all without third-party custody. The contracts are optimized for simplicity and auditability, with upgrade pathways for adding ERC-20 token privacy routing and on-chain governance.

Bot-Chain Communication Layer

EvoPay connects its Telegram bot to the Ethereum blockchain via secure backend relays. Every on-chain action (e.g., private routing trigger, donation confirmation, lending record) is synced with the bot in real time. This dual-recording model ensures verifiability for all transactions.

Wallet Generation

Users can generate new ETH wallets inside the bot using ECDSA-based methods. Private keys are never stored on EvoPay servers. Wallets are stored locally and encrypted within the telegram account using standard AES-256 encryption models. Advanced users can also operate in ephemeral, connectionless mode.

Ecosystem Compatibility

EvoPay is EVM-compatible by design. Future support includes additional chains like Polygon, Arbitrum, and Base — enabling cross-chain payments and fundraising using the same bot interface. Smart contract standards remain compliant with ERC-20/ERC-721 to maximize dApp and DEX interoperability.

Developer-Facing Modules

A structured API and SDK are planned for Phase 4, allowing builders to integrate EvoPay's payment layer into third-party dApps, bots, and platforms. Modular plugin-style components will allow for merchant checkout flows, automated invoicing, and white-label fundraising widgets.
