Rhino.fi Aims for a True Digital Dollar with 1:1 Stablecoin Service

TORTOLA, British Virgin Islands – March 19, 2026 – In a move aimed at solving a persistent and costly problem for the fintech industry, infrastructure provider Rhino.fi today launched Stablecoin 1:1. The new service promises neobanks and B2B payment platforms a predictable way to accept and settle USD-pegged stablecoins, guaranteeing a 1:1 conversion rate between major assets like USDC and USDT across more than 25 different blockchain networks.

For years, the promise of stablecoins has been simple: a digital dollar that moves at the speed of the internet. However, for businesses handling millions in cross-chain transactions, the reality has been far more complex. Hidden spreads, network fees, and routing inefficiencies often mean that a dollar sent is not quite a dollar received, creating uncertainty and financial "leakage" that erodes margins. Rhino.fi's new offering directly confronts this issue, aiming to transform stablecoins from a volatile crypto-asset into a reliable piece of global payment infrastructure.

The Billion-Dollar 'Leakage' Problem

While stablecoins are designed to maintain a peg to the US dollar, the mechanics of moving them across a fragmented landscape of dozens of blockchains introduce significant variability. Businesses that accept payments in both USDT and USDC across networks like Ethereum, Solana, Tron, and Base often face a recurring question with every transaction: “What will I actually receive?”

This isn't just a theoretical concern. Research published in the European Journal of Finance highlights the inherent risk, estimating that major USD-pegged stablecoins carry an annualized devaluation probability that can surge above 2% during periods of market stress. For a company processing high volumes, even minuscule discrepancies add up.

Rhino.fi illustrates this with a stark example: a fintech processing $10 million per month in mixed stablecoins could lose around $5,000 monthly—or $60,000 annually—to an average spread of just 5 basis points (0.05%). This leakage stems from conversion spreads between different stablecoins and the inefficiencies of routing funds across disparate networks. For CFOs and operations managers, this unpredictability complicates treasury management and makes it difficult to treat digital dollars with the same confidence as their fiat counterparts.

A New Standard for Digital Dollars

Stablecoin 1:1 is engineered to eliminate this ambiguity. The service provides clients with a guaranteed 1:1 quote for converting between USDC and USDT, the two largest stablecoins by market capitalization. Instead of hidden spreads, Rhino.fi charges a single, transparent fee that clients can either absorb or pass through to their end customers.

“Stablecoins are meant to be dollars on the internet, but businesses still experience them like fragmented liquidity and unpredictable outcomes,” said Will Harborne, CEO of Rhino.fi, in the announcement. “Stablecoin 1:1 is our step toward making digital dollars truly usable at scale.”

The technology enabling this guarantee is a key differentiator. Rather than relying on external decentralized finance (DeFi) liquidity pools, which are subject to slippage and fluctuating prices, Rhino.fi utilizes its own "internal solver and pre-funded liquidity network." This proprietary infrastructure, developed over six years, continuously monitors global stablecoin exchange rates and allows the company to offer deterministic settlement and near-instant processing across its supported networks, which include major players like Ethereum, Polygon, Arbitrum, TON, and Solana. This approach effectively brings the clarity of a consumer-facing product like Revolut's 1:1 currency conversion into the B2B infrastructure layer.

Navigating a Competitive and Regulated Landscape

Rhino.fi enters a market that is both increasingly competitive and under growing regulatory scrutiny. Major stablecoin issuers like Circle have their own enterprise solutions, including the Cross-Chain Transfer Protocol (CCTP), which enables native USDC transfers between chains. A host of other infrastructure providers, from Cobo to Crossmint, also offer enterprise-grade stablecoin payment services.

However, Rhino.fi’s focus on guaranteeing a 1:1 USDC/USDT swap with an explicit fee directly targets the pain point of financial uncertainty. Its timing is also critical, as global regulators are moving to codify rules for the stablecoin industry. In Europe, the Markets in Crypto-Assets (MiCA) regulation, set to become fully operational in 2026, imposes strict requirements for transparency, 1:1 reserves, and redemption rights. Similarly, the GENIUS Act in the United States, passed in 2025, is establishing a federal framework for payment stablecoins that prioritizes issuer accountability and consumer protection.

These regulatory frameworks are transforming stablecoins from a Wild West phenomenon into a structured component of the financial system. In this new environment, predictability and transparency are no longer just features—they are prerequisites for adoption.

“We’re taking away the ‘which stablecoin, which chain, what will I receive?’ problem,” stated Lexi Short, CGO of Rhino.fi. “Predictability is what turns stablecoins from a crypto feature into real payment infrastructure.”

Early Adoption and the Path Forward

Demonstrating market interest, payments platform WirexPay has already joined as an early design partner for the Stablecoin 1:1 rollout. The partnership will see Wirex leverage Rhino.fi’s cross-chain liquidity infrastructure to enhance its own multi-chain stablecoin payment offerings for a global customer base, aiming for seamless and cost-efficient fund movement.

This collaboration builds on Rhino.fi's established track record, which includes processing over $5.5 billion in bridged volume and onboarding more than two million users to its broader cross-chain solutions. By abstracting away the complexities of blockchain networks and stablecoin types, the company is betting that businesses will be more willing to embrace digital assets for everyday financial operations like B2B invoicing, global remittances, and treasury management.

As the financial world continues to integrate digital assets, the distinction between "crypto" and "finance" blurs. Solutions that prioritize reliability, transparency, and regulatory alignment are poised to build the bridges that will carry trillions of dollars in commerce. By promising that a dollar is a dollar, regardless of which blockchain it lives on, Rhino.fi is making a compelling case for its role in building that future.
