Harmony will advocate for no criminal charges when funds are returned.

“Harmony will advocate for no criminal charges when the funds are returned,” the developers said.

Users in the comments noted the small size of the bounty — 1% of the value of the stolen funds. A popular Twitter crypto trader under the alias Degen Spartan called the offer “an insulting amount”.

“I think these guys are just performing a stunt to soften legal responsibility: ‘Hey, look, don’t blame us, at least we tried.’ It seems they don’t even want to return the money with such a clownish offer,” he added.

Harmony CEO Stephen Tse clarified in a thread that the breach was caused by compromised private keys to the multi-sig wallet, not by any Horizon vulnerability.

3/ The team has found evidence that private keys were compromised, leading to the breach of our Horizon bridge. Funds were stolen from the Ethereum side of the bridge.

As Immunefi notes, crypto projects lost more than $1.22 billion in the first quarter of 2022 due to hacks and fraud.
