Garden Finance Takes App Offline After HTLC Exploit Across Four Networks

Garden Finance temporarily took its app offline after blockchain security firm Blockaid reported an exploit targeting the protocol’s hash time-locked contracts across four blockchain networks. According to Cointelegraph, the attack affected HTLC contracts on Ethereum, Base, Arbitrum and BNB Smart Chain, with about $450,000 in USDT reportedly drained on Sunday. HTLCs are time-bound escrow contracts Garden uses to enable atomic swaps between Bitcoin and assets on other networks. Blockaid said the exploit was ongoing when it issued its alert, but it did not identify the suspected vulnerability or confirm whether user funds were affected. The alert also included addresses linked to the attacker and the affected contracts. Garden said it detected unusual activity and began a full investigation while its app remained temporarily offline. The company and Blockaid both acknowledged Cointelegraph’s request for comments. The incident comes after an October 2025 breach in which an attacker stole about $11.4 million after compromising the operating environment of one of Garden’s solvers. Garden said that earlier breach did not affect its protocol contracts or place user funds at risk.
