How scoring works →Summary
Sentiment is an undercollateralized DeFi lending protocol originally deployed on Arbitrum, later migrating activity to HyperLiquid L1. On April 4, 2023, the protocol suffered a read-only reentrancy exploit resulting in approximately $1 million in losses, of which 90% was returned by the attacker following a negotiated $95,000 bounty. ZachXBT has flagged the entity for elevated risk; the protocol remains operational with a low TVL of roughly $518,000 as of 2025.
