At a glance
Aave ↗ and Radiant Capital ↗ operate in the decentralized lending sector but sit at opposite ends of the maturity spectrum. Aave, launched in 2017, is the category leader with $22B in total value locked across 9 chains. Radiant, forked from Aave v3 and launched in 2022, adds LayerZero cross-chain borrowing but holds just $0.05B in TVL and runs in safe mode after a major October 2024 exploit. This comparison frames the choice between the established giant and the niche cross-chain experiment.
Key differences
Aave commands $22B TVL across Ethereum, Arbitrum, Polygon, Avalanche, Optimism, Base, Metis, BNB, and Gnosis. Radiant Capital manages only $0.05B TVL on just three chains: Arbitrum, BNB, and Ethereum. The scale disparity is roughly 440-to-1.
Aave’s audits come from top-tier firms — Trail of Bits, OpenZeppelin, and Certora — while Radiant’s audits were conducted by Peckshield, Zokyo, and BlockSec, a tier below in reputation and depth. Aave has zero recorded exploits in its history; Radiant suffered a critical exploit in October 2024 that forced the remaining markets into safe mode, limiting functionality.
Product maturity also differs. Aave runs a native stablecoin (GHO), a V4 hub-and-spoke architecture, and institutional products like Horizon. Radiant’s core value proposition — cross-chain lending via LayerZero — remains unproven post-exploit, with the DAO working on remediation and no timeline for full restoration.
Security and track record
Aave’s security posture is among the strongest in DeFi. It has undergone multiple audits by Trail of Bits, OpenZeppelin, and Certora, with no known exploits across its six-year operational history. The protocol’s immutable governance timelocks and the Umbrella safety module further reduce tail risk.
Radiant’s track record is materially weaker. Audited by Peckshield, Zokyo, and BlockSec, it still suffered a major exploit in October 2024. The aftermath left the protocol in safe mode — borrowing and lending are restricted, and the DAO is actively working on a recovery plan. This incident erodes trust in the codebase and the competence of the security review process.
Fees and costs
Specific fee data is not disclosed in our current dataset for either protocol. Both Aave and Radiant use dynamic interest rate models where borrowing costs vary by asset utilization. Liquidation penalties and reserve factors also differ per market. For real-time fee comparisons, consult each protocol’s official dashboard or a DeFi analytics aggregator.
Which should you choose
Pick Aave if you want the deepest liquidity, the widest chain support, and a protocol that has never been hacked. Its v3 markets are the industry standard for institutional and retail lenders alike, and the GHO stablecoin adds native yield optionality.
Pick Radiant Capital only if you specifically need cross-chain borrowing mechanics that bridge liquidity natively via LayerZero, and you are comfortable with the post-exploit risk. Currently in safe mode, the protocol cannot offer its full service; any use should wait until the DAO completes remediation and restores full market functionality.
Verdict
Aave is the clear winner by every measurable metric: TVL, chain reach, audit pedigree, and incident-free history. Radiant’s cross-chain architecture is a meaningful experiment, but the 2024 exploit and tiny market share make it a speculative choice at best. For nearly all lending use cases in 2026, Aave is the superior protocol.
