A number of DeFi protocols that have suffered attacks over the past year have been able to successfully recover at least part of their stolen funds, due in part to post-attack-negotiated bounty offers.

Most prominently, lending protocol Euler Finance — which was exploited for nearly $200 million in a series of flash loan attacks — saw its hacker return 100% of its recoverable funds.

More recently, liquidity protocol Sentiment also managed to recover $900 thousand of its stolen funds, or around 93% of the total stolen. Sentiment had come to an agreement with the attacker, allowing them to keep $66,000 of the hacked funds.

Bridging platform Allbridge, which was drained of $573,000, also ended up in a similar situation.
