DeFi cross-chain protocol Symbiosis says it recovered 15 BTC following a Bitcoin bridge exploit and has offered the attacker a 20% bounty, in a case that once again puts cross-chain infrastructure security at the center of the digital-asset conversation.
The claim was reported by The Block, which said the Symbiosis Bitcoin bridge exploit ended with the team recovering 15 BTC and extending a 20% bounty offer to the person behind the incident. Symbiosis publishes protocol updates on its official blog.
Symbiosis says it recovered 15 BTC after the bridge exploit
According to the reported statement, Symbiosis says it recovered 15 BTC after the Bitcoin bridge exploit. The figure is attributed to Symbiosis, and the available material does not independently establish it on-chain. For related coverage, see Bitcoin slips below $79K as jobs data revives Fed fears.
What the reported 15 BTC recovery establishes
The recovered 15 BTC refers only to the amount Symbiosis says it clawed back. It does not describe the total amount taken in the exploit, and it should not be read as a sign that the incident is fully resolved or that the attacker returned the funds.

Symbiosis offers the attacker a 20% bounty
Symbiosis is offering the attacker a 20% bounty, according to the same report. This is an offer rather than a completed payment or an accepted agreement, and there is no indication the attacker has responded.

What is known about the bounty offer
The available context does not establish which amount the 20% applies to, whether it is calculated against the recovered 15 BTC, the total taken, or another figure. It also does not spell out any deadline, conditions, or legal terms, so no bounty size in BTC can be derived from what has been disclosed here.

What remains unclear about the exploit and recovery
The total amount taken and any remaining shortfall are not established by the available material. Without that figure, the scope of the Symbiosis Bitcoin bridge exploit cannot be measured against the 15 BTC the team says it recovered.

The recovery method, the technical cause of the exploit, and the current operating status of the bridge are likewise not established here. These are limits of the material available for this report, not evidence that Symbiosis has withheld details; the protocol may address them directly on its own channels.
