Symbiosis Says It Recovered 15 BTC, Offers 20% Bounty

Cross-chain protocol Symbiosis says it recovered approximately 15 BTC after a Bitcoin bridge exploit and has offered the attacker a 20% bounty, a security incident that puts fresh focus on bridge risk for the Southeast Asian traders who lean heavily on cross-chain rails to move value between local exchanges. For the region's users, from Jakarta to Manila, bridges are not a niche tool. They are the plumbing that connects assets held on Indodax, Tokocrypto or Coins.ph to DeFi liquidity elsewhere. A vulnerability in that plumbing is a direct concern for anyone routing BTC across chains.

Recovery reported by Symbiosis Approximately 15 BTC Symbiosis said it recovered approximately 15 BTC and secured it on a team-controlled multisig. Recovery has not been independently verified on-chain; final loss accounting remains pending. Importantly, the recovered amount is not the same as the total loss. Symbiosis said final accounting was still in progress and that confirmed figures would come in a later update, so the 15 BTC figure should not be read as full recovery. The protocol said BTC routes were halted and the Bitcoin Bridge was isolated, while describing its EVM, TRON, TON, Octopools and other components as unaffected and operating normally. That is the team's assessment, not an independent safety audit. Bridge incidents have repeatedly rattled sentiment even when broader prices hold, much as Bitcoin has recently traded through competing whale-buying and macro fear signals.

At approximately 04:28 UTC on Sep 11, 2026, attacker exploited a vulnerability in Bitcoin Bridge. BTC routes have been halted. Other routes remain operational and safe.
