Garden Finance disables app as Blockaid reports $450,000 exploit

Blockaid said an attacker drained about $450,000 in USDT from Garden Finance’s HTLC contracts across Ethereum, Base, Arbitrum and BNB Smart Chain.

Cross-chain bridging and atomic swap protocol Garden Finance temporarily took its app offline after blockchain security firm Blockaid reported an exploit targeting the protocol’s hash time-locked contracts (HTLC) across four blockchain networks.

On Sunday, Blockaid said an attacker drained about $450,000 in USDT from Garden’s HTLC contracts on Ethereum, Base, Arbitrum and BNB Smart Chain. HTLCs are time-bound escrow contracts that Garden uses to facilitate atomic swaps between Bitcoin and assets on other networks.

Blockaid described the exploit as ongoing when it published its alert but did not disclose the suspected vulnerability or say whether the incident affected user funds. Blockaid’s alert included addresses associated with the attacker and the affected contracts.
