Another major crypto project is leaving LayerZero behind. Solv Protocol, which manages over $700 million in tokenized Bitcoin, is migrating its cross-chain infrastructure to Chainlink CCIP following a devastating $292 million exploit linked to LayerZero's bridge technology.
Why the Switch?
The move comes on the heels of the Kelp DAO hack, where attackers drained $292 million from a protocol using LayerZero's bridge. Kelp DAO publicly blamed LayerZero for the exploit, citing a single-verifier configuration that allegedly bypassed security recommendations. Solv Protocol didn't name Kelp directly but cited "recent cross-chain hacks observed in the industry" as the catalyst for its own security review.
What's Changing?
Solv is deprecating LayerZero bridge support for Corn, Berachain, Rootstock, and TAC and standardizing on Chainlink CCIP. This affects SolvBTC and xSolvBTC tokens, which represent tokenized Bitcoin across multiple blockchains. The transition aims to provide "institutional-grade security assurance" through Chainlink's multi-verifier system.
The Bigger Picture
Cross-chain bridges remain one of DeFi's most vulnerable points. Past attacks include the $622 million Ronin bridge exploit (linked to North Korea's Lazarus Group) and the $230 million WazirX hack. Solv's migration reflects a growing trend: protocols prioritizing security over interoperability flexibility.
What LayerZero Says
LayerZero previously blamed the Kelp DAO hack on North Korea's Lazarus Group and claimed the project ignored recommendations to use multiple validators. Kelp DAO disputed this, accusing LayerZero of approving the flawed configuration.
Industry Impact
Chainlink's CCIP is gaining traction as a more secure alternative. With Solv's migration, over $700 million in tokenized Bitcoin will now rely on Chainlink's infrastructure, signaling a potential shift in DeFi's cross-chain standards.
"Security is the foundation of everything we build at Solv, and our migration to Chainlink CCIP reinforces that commitment at the highest level." — Will Wang, CTO of Solv Protocol
