Rhino.fi launches stablecoin 1:1 for cross-chain payments

Rhino.fi has launched Stablecoin 1:1, a cross-chain settlement feature for USDT and USDC aimed at businesses that want predictable 1:1 outcomes across more than 25 blockchain networks.

The product is designed for fintechs, wallets, payment services and on-chain finance groups that accept dollar-backed stablecoins and need greater certainty over what arrives after a transfer crosses chains. It offers transparent basis-point fees and removes hidden costs linked to cross-chain swap spreads.

The launch addresses a practical problem in the stablecoin market. Although USDT and USDC are both pegged to the US dollar, businesses can receive slightly different amounts when funds move between chains, venues and liquidity pools.

Those differences can become material at higher volumes. A business handling USD $10 million in monthly stablecoin deposits and settlement flows could lose about USD $5,000 a month from a 5 basis point gap, before accounting for operations, reconciliation and support costs.

How it works

Rhino.fi continuously monitors the exchange rate between USDC and USDT. When market prices stay within pre-set limits, it provides a 1:1 quote so clients can treat the two tokens as interchangeable at deposit, conversion and settlement.

If market conditions move outside those limits, the system switches to a pass-through quote based on the live exchange rate between the two stablecoins. This keeps pricing aligned with market conditions during periods of volatility.

In both cases, Rhino.fi applies a visible basis-point fee. Clients can either absorb that fee themselves or pass it on to customers.

The service now supports USDT and USDC across Ethereum, Tron, TON, Base, Polygon, Arbitrum and Solana, among other networks. Guard rails are set for each client and end user to reduce the risk of arbitrage while keeping the service usable for payment and banking use cases.

Target users

Rhino.fi is targeting businesses that handle cross-border dollar flows and products built around stablecoin deposits and settlement. The tool is intended to reduce the operational burden created by fragmented liquidity across chains and tokens.

That matters for consumer-facing products, where users may hold one stablecoin on one network while the business prefers to settle in another token or chain. A fixed 1:1 outcome under normal market conditions could simplify pricing, treasury management and customer support.

WirexPay has joined the rollout as an early design partner. Rhino.fi has opened the feature in an early pilot for selected partners.

Stablecoin use in payments and financial services has grown quickly, but moving assets across blockchain networks remains a source of friction for businesses. Even where assets are nominally dollar-denominated, differences in routing, liquidity and timing can affect the amount ultimately received.

The aim is to make dollar stablecoins behave more like interchangeable digital dollars, where businesses need certainty. In practical terms, that means 1 USDC equals 1 USDT.
