Radiant Capital shuts down after $50M hack left it…

Radiant Capital announced Monday it is winding down operations after 18 months of failed recovery attempts following a roughly $50 million exploit in October 2024. The DeFi lending protocol said it has been unable to recover a meaningful amount of stolen funds or raise fresh capital, leaving the DAO with no viable path forward.

Why it matters

The collapse of Radiant Capital is a stark case study in how a single catastrophic security breach can permanently destroy a DeFi protocol. The October 2024 attack — in which an attacker deployed a backdoor contract to gain unauthorized access to Radiant's Arbitrum and BNB Chain instances — was itself the second exploit the protocol suffered in 2024, coming months after a flash loan attack that drained roughly 1,900 ETH ($4.5 million) earlier that year. The cumulative damage proved insurmountable. The DAO's own statement captures the brutal arithmetic of post-exploit DeFi survival: "Effort alone is not enough without recovery, capital, or growth."

Market impact

Radiant will enter a "maintenance state" with its frontend and smart contracts remaining live so users can withdraw, repay, and manage positions. Any funds recovered through ongoing legal or investigative efforts will be returned to affected users. The shutdown lands against a deteriorating sector backdrop: DeFi Llama reported that the number of crypto exploits hit a record monthly high in April, with more than 20 discrete hacks logged — the first time that threshold has been crossed. For DeFi lending protocols specifically, Radiant's fate reinforces the existential risk that unresolved security incidents pose to protocol viability and investor confidence.
