Lombard moves over $1 billion of Bitcoin-backed assets to Chainlink

Lombard announced it will migrate more than $1 billion of its Bitcoin‑backed tokens, LBTC and BTC.b, from the LayerZero bridge to Chainlink’s Cross‑Chain Interoperability Protocol (CCIP) following an internal security review triggered by the recent Kelp DAO exploit [2].

Security concerns drive the migration

The Kelp DAO exploit in April drained $292 million from a LayerZero‑powered bridge, raising doubts about the safety of cross‑chain infrastructure [2]. In response, Lombard’s security review concluded that Chainlink’s CCIP offers “independent node operators, built‑in rate limits and audited infrastructure,” prompting the protocol to deprecate LayerZero on multiple networks, including Solana, Etherlink, Berachain, Corn and TAC [2]. Chainlink’s CCIP is also being adopted by other DeFi projects such as Solv Protocol, which is moving $700 million of tokenized Bitcoin, underscoring a broader “flight to quality” across the sector [1][3].

Scale of the shift and market context

Combined, Lombard, Solv, Kelp and other protocols are moving roughly $4 billion of assets to Chainlink’s bridge, a significant reallocation of capital within DeFi [2]. Lombard’s migration represents the largest single Bitcoin‑backed token movement in this wave, surpassing Solv’s $700 million shift [1]. The move aligns with growing institutional expectations for “battle‑tested, highly decentralized” cross‑chain solutions, a standard Chainlink claims to meet and one that U.S. officials have labeled critical digital‑asset infrastructure [1].

Technical and tokenomic details

Lombard’s LBTC and BTC.b tokens are designed as wrapped Bitcoin assets that can be used in lending, yield strategies and other DeFi applications. By adopting Chainlink’s Cross‑Chain Token standard, the tokens will employ a burn‑and‑mint model to move across chains, reducing reliance on a single‑verifier configuration that was blamed for the Kelp breach [2]. The migration will be phased to minimize disruption for users holding positions on the affected networks.

What to watch

• Chainlink CCIP adoption milestones – track announcements of additional protocols joining the bridge, which could further shift capital.
• LayerZero’s response – monitor any technical upgrades or policy changes from LayerZero that might affect remaining assets.
• On‑chain activity for LBTC/BTC.b – watch for large‑wallet transfers or liquidity shifts on the networks slated for migration (Solana, Etherlink, etc.).

Lombard’s $1 bn migration highlights a decisive turn toward higher‑security cross‑chain solutions, suggesting that future DeFi growth may hinge on the robustness of bridge infrastructure rather than convenience alone. The industry’s collective move to Chainlink CCIP raises the question of whether LayerZero can regain trust or will become a legacy bridge for smaller projects.
