What This Contract Does

The RICE Pay Transfer Router is designed to route USDC transfers without custodying user balances.

When a user initiates a transfer, the contract pulls the approved USDC amount from msg.sender and immediately routes the funds to:

  1. the recipient
  2. the RICE Pay fee wallet

The contract is not designed to hold user funds like a vault or escrow.

Fee and Gas

RICE Pay service fee:
0.39%, with a minimum fee of 0.25 USDC and a maximum fee of 3.90 USDC.

Network gas fee:
Gas is separate from the RICE Pay service fee. Gas is paid by the user through their wallet to the Base network. RICE Pay does not receive gas fees.

Trust Signals

The v1 transfer router has:

  • No owner
  • No proxy
  • No admin function to change fees
  • Immutable USDC token address
  • Immutable fee recipient address
  • Fixed fee logic in the contract
  • Source code verified on BaseScan

Allowance Policy

RICE Pay does not require unlimited USDC approval.

The intended flow is exact-amount approval for each transfer. This helps reduce allowance-related risk for users.

Security Notice

Source verified does not mean audited.

The contract source code is public and verified on BaseScan, but it has not yet completed a formal third-party security audit.

RICE Pay plans to pursue an external review or limited-scope audit before meaningful transaction volume.

If a serious issue is found, RICE Pay will stop directing users to the affected contract, mark it as deprecated in the documentation, and publish a new verified contract address.
