Lombard Finance is migrating its Bitcoin DeFi protocol infrastructure from LayerZero to Chainlink, moving roughly $1 billion in Bitcoin assets onto a new messaging layer. The decision follows the Kelp DAO exploit that drained $292 million — a breach that exposed cracks in the cross-chain setup Lombard relied on.
Why the switch
Lombard lets users wrap Bitcoin into a token called LBTC, which can then be used across different blockchains. That bridging relies on an oracle and messaging system. Until now, that system was built on LayerZero. After the Kelp DAO attack, which hit a protocol Lombard shared infrastructure with, the team decided the risk wasn't worth it.
Chainlink's CCIP (Cross-Chain Interoperability Protocol) will replace LayerZero as the backbone. Lombard says the move improves security guarantees and gives them access to Chainlink's existing network of price feeds. For a billion-dollar pool of Bitcoin, that matters.
The Kelp DAO connection
Kelp DAO, a liquid restaking protocol, lost $292 million in what's being called one of the biggest exploits of the year so far. The attack exploited a vulnerability in a cross-chain message passing system — the same type of system Lombard was using. While Lombard itself wasn't hit, the team moved quickly.
The timing isn't great for the broader Bitcoin DeFi space. Wrapped Bitcoin products have been growing fast, and a major exploit on a related project shakes confidence. Lombard's migration is an attempt to draw a line under that.
What users will see
For LBTC holders, the transition should be mostly invisible. Lombard says it's handling the technical work behind the scenes. No tokens need to be migrated manually. The smart contracts on each chain will be updated to point to Chainlink's CCIP instead of LayerZero.
Still, any infrastructure change at this scale carries risk. Lombard is running a series of audits and testnet validations before the final cutover. They haven't given a specific date for completion.
The migration is live in the sense that development work has started. When it finishes, Lombard will be one of the largest Bitcoin DeFi protocols running on Chainlink's CCIP. The $292 million Kelp exploit remains an open wound for the ecosystem, and Lombard's move is a direct response. Whether other protocols follow remains an open question — but the pressure to switch is clearly building.
