What USDC is
USDC is a U.S.-dollar-denominated payment stablecoin issued by regulated affiliates of Circle. Circle states that USDC is backed by highly liquid cash and cash-equivalent assets and redeemable 1:1 for U.S. dollars, subject to its terms. Circle reported $72.3 billion of USDC in circulation as of July 27, 2026 and publishes reserve information and monthly third-party assurance reports.
Why businesses are paying attention
Stablecoin activity is no longer a small technical experiment. Visa’s adjusted methodology estimated $10.2 trillion in stablecoin transaction volume over the prior 12 months, up 63% year over year. Visa also warns that raw blockchain volume includes trading bots, exchange rebalancing and smart-contract activity, so headline transaction figures should not be confused with commercial payments.
A U.S. payment-stablecoin framework now exists
The GENIUS Act became U.S. Public Law 119-27 on July 18, 2025. The law establishes requirements for permitted payment-stablecoin issuers, including one-to-one reserves using specified liquid assets, public redemption policies, monthly reserve disclosures and anti-money-laundering obligations. That framework does not approve RICE Pay or remove state, partner and corridor-specific requirements.
Where USDC can improve the payment experience
- Observable settlement: An on-chain transaction can be checked by both parties without waiting for correspondent-bank status updates.
- Continuous network availability: Blockchain settlement is not restricted to a bank branch schedule, although conversion partners still have cut-off times and review processes.
- Programmable records: Payment status and transaction identifiers can feed a purpose-built payment workspace.
- Customer authorization: Smart-account infrastructure can require the customer to approve the actual transaction.
Where USDC does not remove cost or risk
- Fiat-to-USDC and USDC-to-fiat providers may charge fees or spreads.
- A supplier receiving fiat may receive less than the USDC invoice amount after its own off-ramp costs.
- Business verification, sanctions screening, transaction limits and jurisdiction restrictions still apply.
- Blockchain transactions are generally irreversible, so recipient and amount controls matter.
- USDC is not a bank deposit and is not FDIC insured.
The right comparison
An importer should compare the bank route and the USDC route on the same corridor and amount. Include every bank fee, FX spread, intermediary deduction, conversion-provider fee, RICE Pay charge, supplier off-ramp cost and the operational time spent preparing and reconciling the payment.
Why RICE Pay uses business-friendly wallet infrastructure
RICE Pay is being designed around Particle Network smart-account infrastructure rather than requiring a finance employee to connect a personal browser wallet. Particle Network documents social-login wallet creation, MPC-TSS key security and ERC-4337 smart accounts. RICE Pay’s role is to provide the business payment interface, transaction review and records around that infrastructure.
