RHEA Finance

RHEA Finance is a chain-abstracted DeFi protocol built on NEAR Protocol that unifies decentralized exchange, lending, and liquid staking into a single liquidity hub accessible across multiple blockchains. The project positions itself as the primary liquidity layer for NEAR-based DeFi while leveraging NEAR's Chain Signature technology to extend native access to Bitcoin, Zcash, EVM-compatible networks, and Solana — without requiring users to interact with traditional wrapped assets or custodial bridges.

Origin: A DeFi Merger

RHEA Finance emerged in March 2025 from the merger of two foundational NEAR Protocol DeFi protocols: Ref Finance, the network's leading decentralized exchange, and Burrow Finance, its leading money market. Ref Finance had operated as NEAR's primary AMM since early 2021, and Burrow Finance had established itself as the go-to overcollateralized lending venue on the network. Rather than continue as separate products competing for the same user base and liquidity, the two protocols merged under the RHEA Finance brand to consolidate capital, simplify the user experience, and build toward a broader cross-chain vision.

The merger consolidated the native tokens of both predecessor protocols — REF and BRRR — into a single primary token, RHEA, with a total supply of one billion units. Illia Polosukhin, co-founder of NEAR Protocol, has been associated with the project's founding lineage.

Core Mechanism: Chain Abstraction via NEAR Chain Signatures

The architectural foundation of RHEA Finance's cross-chain capabilities is NEAR's Chain Signature solution. Rather than locking assets in a bridge contract and issuing synthetic tokens on a destination chain, NEAR Chain Signatures allow a smart contract on NEAR to cryptographically sign transactions on external chains — including Bitcoin and EVM networks — at the protocol level. This means a user's position on RHEA Finance can interact with native Bitcoin or native ERC-20 assets without the counterparty risk of a centralized custodian or the complexity of managing wallets across multiple networks.

The protocol launched cross-chain lending in beta on Solflare wallet in November 2025, marking its initial live deployment of this capability with support for USDC, USDT, and ZEC as initial assets. RHEA also integrates with NEAR Intent, a decentralized intent settlement layer, to route cross-chain operations more efficiently.

Product Suite

Decentralized Exchange: The RHEA DEX inherits and extends Ref Finance's AMM infrastructure. It supports permissionless pool creation with customizable fee tiers, standard constant-product pools, StableSwap pools for correlated assets, and Discretized Concentrated Liquidity (DCL) pools that concentrate capital around price ranges to improve capital efficiency. A smart auto-router identifies optimal swap paths across multiple pools in a single transaction.

Lending and Borrowing: Inheriting Burrow Finance's money market, RHEA Lending operates as an overcollateralized lending protocol with volatility-adjusted risk parameters and dynamic interest rate curves. A distinctive feature is the ability to use liquidity provider (LP) tokens from the RHEA DEX directly as collateral, connecting the two protocol arms. RHEA Lending also supports margin trading with leverage of up to 3x.

Liquid Staking: RHEA introduced a native liquid staking token (LST) for NEAR in August 2025, allowing users to stake NEAR and receive a yield-bearing token that retains liquidity and can be used elsewhere within the protocol.

Boost Farming: Liquidity providers can stake LP tokens in farming programs to earn additional incentives on top of trading fees, with rewards denominated in oRHEA tokens.

Aggregator Bridge and Satoshi Ramp: RHEA includes bridging infrastructure to transfer assets from external chains into the NEAR ecosystem. The Satoshi Ramp is a dedicated entry point for Bitcoin users, allowing BTC holders to access yield opportunities without first converting to a wrapped token on another chain.

AI-Powered Vault Recommendations: RHEA incorporates a partnership with Allora Network, a decentralized AI intelligence network, to provide data-driven vault and strategy recommendations within the platform.

Token Ecosystem

RHEA Finance operates a three-token model:

• RHEA: The primary protocol token with a one-billion-unit total supply and the contract address token.rhealab.near on NEAR Protocol. It serves as the base governance and value-accrual token. The RHEA token became tradeable on Bitget in the Innovation Zone beginning July 30, 2025.

• xRHEA: Staked RHEA with an elastic supply. xRHEA functions as the ecosystem's utility token for gas abstraction within RHEA's cross-chain operations and as a collateral asset within the lending protocol. Holders gain access to enhanced governance rights and contribute to on-chain reputation metrics.

• oRHEA: A liquidity incentive token earned through farming and yield programs. It converts to RHEA at a variable rate determined partly by a user's reputation score within the ecosystem, creating incentives for long-term participation over mercenary liquidity.

Security

RHEA Finance has engaged two professional security firms — BlockSec and SlowMist — for smart contract audits. The protocol also runs a bug bounty program through Immunefi, the industry-standard platform for DeFi vulnerability disclosure, providing an ongoing security layer beyond point-in-time audits.

Fit in the Broader Ecosystem

RHEA Finance occupies the role of infrastructure-level liquidity layer within the NEAR ecosystem, serving as the canonical AMM and money market in the same way that protocols like Uniswap or Aave anchor their respective chains. Its cross-chain positioning extends its relevance beyond NEAR alone: the November 2025 launch of cross-chain lending through Solflare — a Solana-native wallet — represents a direct integration point between NEAR's chain-abstracted liquidity layer and Solana users. Rather than requiring Solana users to bridge assets to NEAR, RHEA's chain abstraction model allows them to interact with NEAR-side liquidity from familiar infrastructure.

By combining the liquidity depth inherited from Ref Finance, the money market mechanics of Burrow Finance, and NEAR's native chain abstraction layer, RHEA Finance is building toward a DeFi experience where chain boundaries become invisible to end users — capital moves to wherever it earns best, and users interact with a single interface rather than a fragmented set of protocol frontends scattered across networks.
