Rhea Dex

Rhea Dex receives a B- risk grade (30/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — established NEAR DeFi position provides foundation, but post-merger integration complexity and multi-chain attack surface add meaningful risk, with inherited audit history providing some security assurance. Rhea Dex is a multi-chain decentralized trading and lending platform formed from the February 2025 merger of Ref Finance (NEAR's primary DEX) and Burrow Finance (NEAR lending protocol). Supporting 7+ chains including Bitcoin, NEAR, Base, Arbitrum, and Ethereum, it aggregates cross-chain liquidity for seamless trading and lending. With approximately $21M TVL and $15M FDV, its B risk grade reflects the complexity of post-merger integration, the broad multi-chain attack surface, and NEAR ecosystem concentration, balanced by inherited audit history from Ref Finance and established NEAR DeFi market position.

The key risks identified for Rhea Dex are: (1) Rhea was formed by merging two separate protocols (Ref Finance DEX and Burrow Finance lending) in February 2025. Integrating two distinct codebases creates risk that incompatible assumptions between the DEX and lending components could create new, unforeseen vulnerabilities. (2) The protocol operates across 7+ blockchains including Bitcoin, NEAR, and multiple EVM chains. This broad cross-chain deployment creates a large attack surface where a vulnerability on any single chain could affect the entire platform's liquidity. (3) Despite multi-chain ambitions, core liquidity and the primary user base remain concentrated on NEAR. If NEAR ecosystem activity declines, Rhea's revenue and utility would contract significantly, potentially making cross-chain operations economically unviable. (4) The token migration from REF to RHEA creates a transitional period where governance may be disrupted and token holders face migration complexity.

Rhea Dex scores 30/100 across eight risk dimensions: Mechanism Novelty: 3/15, Interaction Severity: 5/20, Oracle Surface: 0/10, Documentation Gaps: 4/10, Track Record: 6/15, Scale Exposure: 3/10, Regulatory Risk: 4/10, Vitality Risk: 5/10. The highest risk area is Vitality Risk at 5/10.

Among 111 rated DEX protocols on Hindenrank, Rhea Dex ranks #43 by safety (lowest risk score = safest). Its 30/100 risk score and B- grade place it in the middle tier of DEX protocols.
