Symbiosis Recovers $1.1M in Bitcoin from Bridge Exploit, Offers New Bounty

Cross-chain liquidity protocol Symbiosis has recovered 15 Bitcoin worth around $1.1 million from a recent bridge exploit.

The attack affected Symbiosis' native Bitcoin bridge, which remains paused, and the attacker's address minted 46.1 billion unbacked tokens but realized net proceeds of only 4.3 Wrapped Bitcoin (WBTC), valued at $336,000, according to blockchain security firm Blockaid.

Symbiosis initially offered a 20% white-hat bounty for the attacker to return the funds, with a deadline that expired on Sunday. However, the protocol is now offering an additional 20% bounty to anyone who provides information leading to asset recovery.
