Symbiosis Recovers 15 BTC After Bridge Exploit, Offers Attacker 20% Bounty

The recovered 15 BTC against roughly 46.1 billion syBTC minted points to a familiar bridge failure mode: the mint was enormous on paper, but the realizable value was far smaller, which limits the damage and strengthens Symbiosis's leverage in negotiating. The 20% bounty is a standard white-hat incentive, effectively a bid to turn the attacker into a returner rather than a pursued counterparty. Whether the remaining funds come back, and how the syBTC mint is unwound, is the open question.
