MoniPayRouter

The MoniPayRouter is the central hub of the MoniPay protocol. It is responsible for processing all payments, verifying signatures, and distributing fees.

Core Functions

executePayment

The primary function used by relayers to submit a gasless payment.

• Parameters: Sender address, recipient address, amount, nonce, signature.
• Logic:
  1. Verifies the EIP-712 signature against the sender's address.
  2. Checks the nonce to prevent replay attacks.
  3. Transfers 99% of the amount to the recipient.
  4. Transfers 1% of the amount to the protocol treasury.
  5. Emits a PaymentExecuted event.

registerMoniTag

Maps a human-readable MoniTag to a wallet address.

• Parameters: MoniTag string, owner address.
• Logic: Ensures the MoniTag is unique and updates the global registry.

Security Features

• Replay Protection: Each transaction requires a unique, incrementing nonce.
• Signature Verification: Uses OpenZeppelin's ECDSA library for robust signature validation.
• Access Control: Only authorized relayers can call executePayment to prevent spam, though the signature itself ensures only the user can authorize the movement of their funds.
