RHEA Finance

RHEA Finance is a chain-abstracted liquidity protocol built on NEAR Protocol, formed in early 2025 through the strategic merger of two of NEAR's most established DeFi applications: Ref Finance, the ecosystem's primary decentralized exchange, and Burrow Finance, its leading lending protocol. Rather than operating as two separate products, the merged entity consolidates their liquidity, infrastructure, and communities into a single unified platform designed to serve users across NEAR, Bitcoin, Ethereum-compatible chains, Solana, and Arbitrum from one interface.

Background: Two Protocols, One Platform

Ref Finance had established itself as the foundational DEX on NEAR, offering permissionless pool creation, stable swap pairs, and discretized concentrated liquidity (DCL) pools that function as on-chain order books. Burrow Finance built out NEAR's money market infrastructure, allowing users to earn yield on deposited assets and borrow against collateral with dynamic interest rate curves calibrated to utilization.

The February 2025 merger announcement framed the consolidation as a direct response to DeFi fragmentation—the reality that users managing assets across chains must juggle separate interfaces, wallets, and liquidity pools to optimize positions. By combining the two protocols under a shared architecture, RHEA Finance aimed to eliminate those coordination costs while expanding into cross-chain territory that neither predecessor addressed on its own.

Core Products

Decentralized Exchange: RHEA inherits Ref Finance's full trading stack. This includes standard AMM pools, stable swap pools for correlated assets such as stablecoin pairs, and DCL pools that give liquidity providers range orders comparable to a limit order book. A smart routing engine finds optimal execution paths across all available pools. The platform also supports margin trading at up to 3x leverage.

Money Market: From Burrow Finance, RHEA brings a lending protocol with multi-dimensional collateral risk assessment and dynamic borrow rates that adjust with supply and demand conditions. LP tokens minted from the DEX side can be posted as collateral on the lending side, enabling capital-efficient strategies that move between trading and credit within the same protocol.

Chain Abstraction Layer: Built on NEAR's Chain Signature technology, RHEA extends beyond the NEAR ecosystem to let users interact with assets on Bitcoin, Ethereum, Arbitrum, Base, BSC, Solana, and Zcash without manually bridging. Two routing components—the Auto Router and Multi-chain Router—handle transaction pathfinding across chains. The platform integrates with NEAR's OmniBridge and other major EVM bridge solutions for asset movement.

Satoshi Ramp: A dedicated Bitcoin on- and off-ramp designed for BTC holders who want access to DeFi yield without going through centralized exchange intermediaries. It connects Bitcoin directly into RHEA's liquidity and lending pools.

Developer SDK: RHEA provides an SDK (the Rhea SDK) for external developers to build applications on top of the protocol's liquidity infrastructure.

Target Users

The platform addresses four primary user segments: participants already active in the NEAR ecosystem; Bitcoin holders seeking yield without selling BTC; EVM-native traders looking for cross-chain opportunities; and speculative traders from Ethereum, Base, Solana, and the Bitcoin Ordinals ecosystem. The Satoshi Ramp and chain abstraction features are designed specifically to lower the technical barrier for the Bitcoin cohort.

Token Structure

The merger consolidated the two legacy tokens—REF from Ref Finance and BRRR from Burrow Finance—into a single primary token: RHEA, with a total supply of one billion. Two utility tokens complement it:

• xRHEA: The staked form of RHEA, earned by locking RHEA tokens. It serves as the governance token for RHEA DAO and also functions as a gas token within the ecosystem.
• oRHEA: A rewards token distributed to liquidity providers, convertible into RHEA based on the holder's activity level and reputation within the protocol.

RHEA DAO governs protocol parameters. The RHEA token launched on Bitget in the Innovation Zone on July 30, 2025 (RHEA/USDT pair) and was subsequently listed on LBank. The contract address on NEAR is token.rhealab.near.

Security and Partnerships

The protocol has undergone security audits by Blocksec and Slowmist. Notable ecosystem partners include NEAR Protocol, OKX, Frax, and Coin98.

2025 Performance

NEAR Protocol's year-end recap cited RHEA's 2025 performance as $10 billion in total trading volume, cross-chain DeFi activity spanning Zcash, Solana, Arbitrum, and Bitcoin, and over 1,000 unique users utilizing cross-chain features. These figures reflect the combined output of the newly merged platform across its first full year of operation.

Relationship to Solana

While RHEA Finance is anchored on NEAR Protocol, Solana is one of the supported source chains within its cross-chain abstraction layer. Users holding Solana-native assets can access RHEA's trading and lending products without manually bridging to NEAR first—the protocol's routing infrastructure handles chain-level settlement in the background. This positions RHEA as part of the broader multi-chain liquidity landscape that Solana participants interact with.
