Radiant Capital will shut down operations and enter a wind-down phase after failing to recover about $50 million lost in a 2024 security breach and being unable to raise new capital over the past 18 months.
Protocol moves to maintenance mode
The decentralized finance lending protocol said its decentralized autonomous organization no longer has a viable path forward. The team has been keeping the protocol running and supporting users under what it described as difficult conditions but concluded there is no sustainable way to continue development.
Radiant will keep its frontend and smart contracts in a “maintenance state.” Users will still be able to withdraw, repay, and manage existing positions, but new lending activity, feature upgrades, and incentive programs have been halted. The project said that if any assets are recovered in the future, they will be returned to those affected by previous exploits.
2024 hacks eroded liquidity and usability
Radiant’s shutdown traces back to a series of security incidents in 2024.
The largest breach hit the protocol’s deployments on Arbitrum and BNB Chain, where an attacker used a backdoor contract to gain unauthorized access. Blockchain analytics firm Arkham Intelligence estimated losses at around $51 million across those networks. Radiant’s Ethereum and Base deployments were not affected in that incident.
Earlier in 2024, Radiant suffered a separate flash loan exploit that drained about 1,900 ETH, worth roughly $4.5 million at the time. The repeated attacks cut into the protocol’s liquidity base and limited its usability, undermining efforts to rebuild confidence and attract fresh capital.
Struggle to recover proves decisive
The decision to wind down reflects Radiant’s inability to recoup stolen funds or secure new financing more than a year after the breaches. The episode underlines a broader trend in decentralized finance: the immediate losses from a hack are often followed by a drawn-out struggle to restore liquidity and credibility.
For many platforms, including Radiant, failure in that second phase can be decisive, leading to a slow contraction and eventual shutdown rather than an abrupt collapse. Radiant’s case highlights that a protocol’s long-term survival depends not only on patching vulnerabilities, but also on demonstrating it can recover assets and rebuild trust.
DeFi security risks remain elevated
Radiant’s closure comes amid continuing security problems across decentralized finance. Data from DeFi Llama showed April recorded more than 20 separate exploits, the highest monthly count to date, even though total dollar losses did not set a new record.
By mid-April 2026, more than $750 million had been lost to hacks and exploits across the sector. Two incidents dominated the totals: attacks on Kelp DAO and Drift Protocol combined for over $577 million in losses.
Recent exploits have increasingly targeted complex parts of the infrastructure rather than simple smart contract bugs. The Kelp DAO attack, which drained about $292 million, focused on weaknesses in the infrastructure that verifies messages between blockchains, exposing structural risks for platforms that rely on cross-chain bridges and bridged assets.
Capital flight and shifting market preferences
The cumulative impact of large-scale hacks has been visible in market behavior. In the weeks following the major April exploits, data indicated nearly $14 billion exited the DeFi ecosystem, as market participants reassessed security across interconnected protocols.
May 2026 saw 80 separate security incidents, underscoring that the threat level remains high even when monthly loss totals vary.
Across the market, capital has been gravitating toward platforms with clearer security frameworks, reduced reliance on third-party bridges, and stronger governance controls. Radiant’s failure underscores that protocols are now judged not only on yield or features, but on proven resilience, recovery capability, and the ability to maintain trust after an attack. For traders, that shift is increasingly shaping which platforms retain liquidity and which struggle to survive.
