Symbiosis Recovers 15 BTC, Offers Hacker 20% Bounty
The 20% white-hat offer is the novel beat, but the gap between 46.1 billion syBTC minted and the $336,000 actually extracted is the structural read for cross-chain bridges.
Lombard Staked BTC (LBTC) is a liquid staking token built to extend Bitcoin's utility into decentralized finance. Issued on multiple blockchain networks, including Ethereum and Base, with availability across ecosystems such as BNB Chain, Solana, Sui, Starknet, Berachain, and others, LBTC is designed as a universal, cross-chain representation of BTC. Each token is backed 1:1 by Bitcoin, preserving a direct reserve relationship with the underlying asset. The token's primary function is to make staked Bitcoin usable. Through integration with Babylon's staking infrastructure, holders can earn staking yields while still maintaining a liquid, transferable token. This yield-bearing characteristic allows LBTC to function as productive collateral rather than idle Bitcoin. Holders can deploy it across a broad range of DeFi activities, including trading, lending, borrowing, and yield farming, on supported networks. As a liquid restaking token with a multi-chain footprint, LBTC represents an effort to standardize Bitcoin participation in DeFi, offering a single asset that bridges native BTC security with the programmability of smart contract platforms.

Ledger's CTO publicly disputes the framing, comparing the drain to the Ronin hack while exchanges freeze LBTC. Blockstream says the SideSwap key was used, not compromised.
The capital flight — triggered by April's $292M Kelp DAO exploit — is reshaping the cross-chain bridge market, with Chainlink's CCIP picking up clients and scrutiny that LayerZero once dominated.
