rhino.fi

rhino.fi is a cross-chain stablecoin infrastructure platform providing enterprise-grade settlement tools for fintechs, neobanks, and payments businesses that need to move value across blockchains at scale. Founded in 2019 as Ethfinex — a spinoff of crypto exchange Bitfinex — the project rebranded to DeversiFi in August 2019 before adopting the rhino.fi name in 2021. CEO Will Harborne and co-founders Daniel Yanev and Ross Middleton have steered the platform through several product evolutions, from an Ethereum Layer 2 trading exchange to one of DeFi's most active retail cross-chain bridges, and ultimately to its current focus as a B2B stablecoin infrastructure layer.

From Bridge to Infrastructure

rhino.fi's early architecture was built on StarkEx Validium, a zero-knowledge Layer 2 solution that anchors user funds to Ethereum's security guarantees while settling transactions off-chain. That foundation made it fast and cheap enough to compete in the cross-chain bridging market, and by the end of 2024 the platform had processed approximately $4 billion in stablecoin volume and onboarded more than two million users to its retail bridge.

In early 2025, rhino.fi announced a strategic pivot. The retail bridge — which let individual users move tokens across 30+ blockchains through the app.rhino.fi interface — was deprecated in July 2026. The new direction focuses entirely on the B2B segment: selling the same cross-chain routing infrastructure as an API product to teams building neobanks, remittance services, card programs, DEX aggregators, RWA platforms, and payroll products.

How It Works

At the core of the current product suite is the Stablecoin Activation Stack, which rhino.fi describes as covering "everything from deposit and routing to settlement, compliance and automated on-chain activation."

Smart Deposit Addresses are the key onboarding primitive. A business integrating rhino.fi's API generates a single deposit address for each user or payment flow. That address accepts USDC or USDT arriving from any of the 30+ supported chains, including Ethereum, Solana, Tron, Base, Arbitrum, Optimism, BNB Chain, TON, Polygon, zkSync, Starknet, Scroll, Taiko, Blast, Stellar, and others. Once funds land, rhino.fi automatically routes and settles them to the destination chain the integrator specifies — no manual intervention, with typical activation in under ten seconds.

Stablecoin 1:1, launched in March 2026, addresses a pain point for businesses accepting both USDC and USDT. The two dollar-pegged stablecoins frequently trade at a small spread relative to each other, and that gap compounds at scale: rhino.fi estimates a business processing $10 million monthly can lose roughly $5,000 to hidden conversion costs. The 1:1 product continuously monitors live exchange rates and guarantees settlement at genuine parity, with transparent fixed fees and no hidden spreads, across 25+ blockchains including Solana.

The platform also offers configurable speed tiers for settlement, MEV protection on bridge routes, and automated on-chain actions that let integrators trigger smart contract calls immediately after funds arrive — eliminating the manual step of a user approving a transaction after a deposit clears.

Compliance and Security

rhino.fi screens 100% of inbound deposits through Know Your Transaction (KYT) tooling and provides compliance audit trails for each transaction. This positions the platform for enterprise customers operating under regulatory frameworks that require AML-grade transaction monitoring.

The platform reports a 99.99% transaction success rate across production traffic. Its original StarkEx Validium architecture was independently audited as part of the broader StarkWare audit program, with user funds cryptographically linked to Ethereum's security model. The team has not publicly disclosed a full list of third-party audit reports for the current bridge and API infrastructure.

DVF Token

The platform's governance token, DVF, launched alongside the DeversiFi brand with a maximum supply of 100 million tokens. DVF was originally used for fee discounts, governance votes, and staking in the platform's liquidity pools. With the pivot away from retail DeFi, the practical role of DVF in the current B2B infrastructure product is limited, and the team has not publicly outlined a revised tokenomics roadmap tied to the new product direction. DVF remains tradable on secondary markets.

Strategic Partnerships

In January 2024, Tether and rhino.fi announced a strategic alliance to enhance USDT utility across DeFi. The partnership covers seamless USDT bridging across networks including Ethereum, Arbitrum, Optimism, zkSync, Polygon, Starknet, BSC, Scroll, and Avalanche, with planned rollout to Tron, Base, and Solana. Paolo Ardoino, Tether's CEO, described it as "a significant step in expanding the accessibility, efficiency and utility of USDT across various blockchain ecosystems."

rhino.fi is also a member of the Circle Alliance, supporting USDC routing across its network. Integrators publicly named as live partners include LINE NEXT (operating Unifi), Plasma One, and Extended. The Stellar network integration, bringing $2 million in liquidity for instant settlement to and from Stellar, went live in July 2026.

Solana Integration

Solana has been part of rhino.fi's supported chain set since 2024, when the team added it alongside Tron and Avalanche as the first non-EVM networks on the platform. The integration enables USDC and USDT deposits from Solana wallets to settle on any of the 30+ destination chains, and vice versa. Solana is explicitly listed as one of the chains supported by the Stablecoin 1:1 product, meaning businesses can offer their users guaranteed dollar parity when accepting SOL-native stablecoin deposits and settling on Ethereum or other EVM chains.

Fees from Solana are among the lowest on the platform — rhino.fi has advertised $0.01 per bridge transaction plus gas, with most routes completing in under a minute. The fast finality and low transaction costs on Solana make it a natural fit for the payment and remittance use cases rhino.fi targets.

Outlook

By mid-2026, rhino.fi had processed over $15 billion in total stablecoin volume and was targeting expansion to 40+ blockchains. The team's near-term roadmap includes merchant checkout flows, fiat onboarding rails, and support for additional regulated stablecoins such as EURC, PYUSD, and emerging RWA-backed instruments. Having closed the retail chapter of its history, the platform is positioning itself as settlement-layer infrastructure for the fintech and payments industry's growing use of stablecoins as a dollar-on-rails mechanism.
