Solv Protocol said it will replace LayerZero with Chainlink for cross-chain transfers tied to more than $700 million in tokenized bitcoin. The team plans to phase out LayerZero support for SolvBTC and xSolvBTC across multiple networks, following a recent $292 million exploit involving a LayerZero-powered bridge.
Solv Protocol said it will end LayerZero bridging for SolvBTC and xSolvBTC on Corn, Berachain, Rootstock, and TAC. The platform named Chainlink’s Cross-Chain Interoperability Protocol (CCIP) as its official infrastructure for cross-chain operations.
Solv stated that CCIP will secure more than $700 million in assets. The protocol said it reviewed its bridge providers after recent industry events and that CCIP offered the strongest security assurances due to its “secure-by-default architecture.” Solv added that CCIP includes native risk controls and proactive monitoring.
The protocol described CCIP as the “gold standard” for decentralized interoperability and said the White House recognizes CCIP as critical digital asset infrastructure. Solv confirmed it will complete the migration in phases.
Solv’s move follows a $292 million exploit on Kelp DAO that used LayerZero infrastructure. The attacker drained 116,500 rsETH through a single-verifier Omnichain Fungible Token bridge, with reports linking the activity to North Korea’s Lazarus Group.
Solv said the incident contributed to bad debt on the Aave protocol after the drained assets circulated. LayerZero and Kelp DAO later disputed responsibility for the breach. LayerZero said it warned against a 1-of-1 decentralized verifier network configuration.
Kelp DAO responded that LayerZero recommended the single-verifier setup during onboarding and said 47% of LayerZero applications use that configuration. Earlier this week, Kelp DAO also confirmed it will migrate to Chainlink.
Solv did not directly reference the Kelp incident in its announcement. Instead, it said it chose a provider that meets higher security standards, adding that “cross-chain bridges remain one of the most sensitive and high-risk areas in DeFi.”
Solv said insecure bridges can create systemic risks across decentralized finance and that recurring security incidents reinforced the need for stronger decentralization. The protocol stated it requires interoperability solutions with robust security design.
Solv also disclosed that it faced an exploit in March affecting one of its Bitcoin Reserve Offerings vaults. Attackers drained about $2.7 million from the BRO token vault. Solv said it reported the incident and addressed the loss at the time.
The latest migration focuses on securing tokenized bitcoin assets across multiple chains. Solv confirmed that CCIP will serve as its standard bridge infrastructure going forward and said it has begun implementing the transition across supported networks.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
