Lido contributors have published security principles explaining why the protocol’s network extension committee selected Chainlink CCIP for cross-chain deployment of liquid staking tokens. This decision reflects increased scrutiny of bridge infrastructure in the wake of large-scale cross-chain exploits, including the recent Kelp/LayerZero vulnerability, where nearly $3 billion in funds were stolen.
Cross-chain bridges have become an important security frontier for DeFi protocols that extend beyond the origin chain. The choice of bridge infrastructure directly impacts token security, operational safeguards, and issuer control. The framework published by Lido outlines the evaluation criteria used to evaluate candidate solutions, with a focus on mitigating risks demonstrated by past exploits.
Chainlink CCIP (Cross-Chain Interoperability Protocol) provides cross-chain token transfer functionality and is integrated into Lido’s multi-chain strategy. This protocol wrapped stETH (wstETH) is now supported via Chainlink’s CCIP infrastructure.
Historical data on cross-chain bridge hacks highlights the scale of the security risk. Lido’s Network Extension Committee has established a formal governance process for evaluating protocol extensions, as documented in community governance discussions.
