Rhino.fi has launched Stablecoin 1:1, a new solution aimed at giving neobanks and fintech companies a predictable way to accept and settle USD-pegged stablecoins across more than 25 blockchain networks, with transparent fees and no hidden spreads.
The product addresses a key challenge in stablecoin transactions, where conversions and multi-network routing can lead to discrepancies despite them being designed to track the US dollar at a 1:1 ratio.
Research published in the European Journal of Finance estimates that major USD-pegged stablecoins carry an annualized devaluation probability averaging 60 basis points under normal conditions, rising above 200 during periods of market stress. For fintechs accepting and settling USD-pegged stablecoins, that creates spread uncertainty, routing complexity, and a recurring question with every transaction: ‘What will I actually receive?’
Even small spreads can result in significant financial impact at scale. In an illustrative scenario, a client processing $10 million per month in mixed stablecoins and losing 5 basis points (0.05 percent ) to conversion spreads and routing inefficiencies could incur approximately $5,000 in monthly losses.
With Stablecoin 1:1, Rhino.fi said it continuously monitors the global stablecoin foreign exchange rate between USDC and USDT and returns a 1:1 quote with a clear, explicit fee and no hidden spreads. Clients can choose whether to absorb the fee or pass it on to end users.
The launch builds on growing expectations for parity between fiat currency and stablecoins. Revolut set the expectation for 1:1 USD and stablecoin conversion for consumers. Stablecoin 1:1 brings that same clarity into the B2B infrastructure layer, allowing fintech firms to treat USDT and USDC as interchangeable USD units for acceptance and settlement, regardless of the originating blockchain.
Rhino.fi has spent six years developing API infrastructure for stablecoin deposits and settlement, with Stablecoin 1:1 representing the latest addition to its platform, targeting use cases such as payments, remittances and B2B invoicing.
Will Harborne, CEO of Rhino.fi, said that, “Stablecoins are meant to be dollars on the internet, but businesses still experience them like fragmented liquidity and unpredictable outcomes. Stablecoin 1:1 is our step toward making digital dollars truly usable at scale.”
The product supports USDT and USDC across more than 25 blockchain networks, including Ethereum, Tron, TON, Base, Polygon, Arbitrum and Solana. The company added that safeguards have been implemented at both client and end-user levels to prevent arbitrage exploitation. WirexPay has joined the rollout as an early design partner.
The launch comes as stablecoins gain traction as payment infrastructure, with increasing emphasis on predictability and transparency. Regulatory developments, including frameworks such as MiCA in Europe, are also shaping the sector, alongside broader global engagement on stablecoin payment use cases.
