Kraken to replace LayerZero with Chainlink for kBTC, future wrapped assets

Kraken said it will replace LayerZero, a protocol for moving crypto assets across blockchains, with Chainlink’s equivalent after the $292 million bridge exploit that hit liquid restaking protocol Kelp last month exposed risks in legacy cross-chain infrastructure.

Chainlink’s Cross-Chain Interoperability Protocol (CCIP) will become the exclusive cross-chain service for Kraken’s wrapped crypto assets including kBTC, its wrapped bitcoin, the crypto exchange said in a statement.

The move follows similar migrations by platforms including Kelp, Solv and Re. Kelp lost 116,500 rsETH (restaked ether) from a LayerZero-powered bridge in 2026’s largest exploit in April. LayerZero later said it “made a mistake” by allowing its own verifier network to secure high-value assets in the configuration used. In total, an estimated $3 billion in total value locked has since migrated.

Kraken’s migration covers various blockchains including Ink, Ethereum, Unichain and Optimism, with others to follow. Kraken introduced kBTC in 2024 as a 1:1 bitcoin-backed token available first on Ethereum and OP Mainnet. The token now has a $260 million market capitalization, CoinGecko data shows.

CCIP will handle the movement of Kraken’s wrapped assets under the Cross-Chain Token standard. Kraken will continue to issue and custody the assets, the firms said.

Rival crypto exchange Coinbase (COIN) also selected Chainlink CCIP last year as the sole bridge for about $7 billion in wrapped tokens.

Kraken’s parent company, Payward, applied this month for a federal trust charter in a bid to become a federal crypto bank.
