Solv Protocol ends the LayerZero bridge, Chainlink takes over $700 million in assets

Solv Protocol, a Bitcoin-centric DeFi platform, published an announcement on May 7 (Thursday), stating that it would gradually discontinue LayerZero’s bridging support for SolvBTC and xSolvBTC. It will adopt Chainlink’s cross-chain interoperability protocol (CCIP) as the official cross-chain infrastructure solution, involving assets worth over $700 million.

Migration scope and Solv Protocol official statement

According to a Solv Protocol announcement dated May 7, 2026, this infrastructure migration covers the bridging services for SolvBTC and xSolvBTC across Corn, Berachain, Rootstock, and TAC, with total managed assets worth over $700 million.

In its announcement, Solv Protocol said: “In light of recent industry events, Solv has reviewed its existing bridge adapters and found that CCIP provides the strongest security guarantees through its default security architecture, native risk controls, and proactive monitoring.”

The Solv Protocol announcement further claims that Chainlink CCIP has been officially recognized by the White House as critical digital asset infrastructure, and that it is characterized as the “gold standard” for decentralized interoperability. However, the announcement does not provide the specific source documents for this recognition. When explaining the reasons for the migration, Solv Protocol did not directly mention the Kelp DAO security incident or the decision by Kelp DAO to migrate.

Background on the Kelp DAO attack and the dispute over LayerZero’s responsibility

According to a May 7, 2026 report by The Block, Kelp DAO suffered a security attack in April 2026, losing $292 million. The attackers were attributed to North Korea’s Lazarus Group. The Block reported that the attackers used an Omnichain Fungible Token (OFT) bridge single-verifier configuration to steal 116,500 rsETH from Kelp DAO, which led to large volumes of bad debt appearing in the Aave protocol.

After the incident, LayerZero criticized Kelp DAO for using a 1:1 decentralized verifier network (DVN) setup and claimed it had issued warnings beforehand. Kelp DAO countered that this setup is a LayerZero default recommendation and noted that 47% of LayerZero applications use the same single-verifier configuration. According to The Block, earlier this week, Kelp DAO also announced that it would abandon LayerZero and switch to Chainlink as the cross-chain infrastructure.

Solv Protocol’s own security track record

According to The Block, Solv Protocol itself was attacked in March 2026, and its Bitcoin reserves issuance (BRO) token vault lost about $2.7 million.
