Solv Protocol Abandons LayerZero Following Kelp Hack

Solv Protocol shifts from LayerZero to Chainlink's CCIP after security review.

The Bitcoin project Solv Protocol has abandoned the cross-chain infrastructure LayerZero in favor of CCIP from Chainlink. 

After an extensive security review, we have decided to deprecate @LayerZero_Core bridges for SolvBTC and xSolvBTC, and migrate to @Chainlink CCIP as our official cross-chain infrastructure solution for $700M+ in tokenized BTC (SolvBTC & xSolvBTC).

The developers will gradually cease support for bridges for SolvBTC and xSolvBTC in the Corn, Berachain, Rootstock, and TAC networks. The Chainlink protocol will become the primary means of interacting with these assets. 

Solv explained the decision as a reassessment of risks following recent incidents in the DeFi sector.

“Cross-chain bridges remain one of the most sensitive and risky areas of the industry. Unsafe platforms create systemic risk for the entire ecosystem,” the statement said.

The team noted that during the review, CCIP outperformed competitors in terms of security: its architecture is secure by default, and built-in risk controls and continuous monitoring are part of the basic configuration.

Context 

Solv’s decision followed the April hack of Kelp involving $292 million. The attack was linked to a LayerZero-based bridge.

The perpetrator exploited a single verifier configuration and issued 116,500 unsecured rsETH. The subsequent use of these assets in DeFi protocols, including Aave, resulted in a large irrecoverable debt. 

After the exploit, parties disagreed on the causes. The Kelp team also announced a shift from LayerZero to CCIP.

On May 7, Aave liquidated the hacker’s remaining rsETH positions as part of an approved recovery plan.
