layerzero

LayerZero is a cross-chain interoperability protocol designed to enable developers to seamlessly issue, connect, and scale assets or applications across multiple blockchains. The protocol provides permissionless infrastructure through a decentralized architecture, with core functionalities including fully composable liquidity transfer and support for cross-chain messaging and the Omni-Chain Asset (OFT) standard. By separating the underlying communication logic from the application layer, LayerZero allows smart contracts on different networks to interact directly, thereby eliminating the complexity of cross-chain bridging and enhancing asset utilization and development efficiency.

first_img Chainlink released CCIP 2, allowing enterprises to customize cross-chain security verification

On Monday, the oracle network Chainlink released the cross-chain interoperability protocol CCIP 2, making significant upgrades to its communication and cross-chain bridge infrastructure. The new version allows enterprises to add their own security verification checks on top of Chainlink's default network of 16 independent node operators. Enterprises can run their own validators or hire external service providers such as Infosys and Nethermind. Chainlink stated that users should not be forced to become "cross-chain security infrastructure experts."This upgrade comes about five months after the Kelp DAO was hacked in April of this year. The attackers are reportedly linked to the North Korean Lazarus group, stealing approximately $292 million in rsETH by deceiving the single validator relied upon by the Kelp cross-chain bridge, which operates on LayerZero. LayerZero blamed Kelp for using only a single validator, while Kelp stated that LayerZero employees had reviewed its setup and raised no objections. Kelp subsequently announced that it would migrate rsETH to Chainlink.The upgrade also adjusts the security mechanism that Chainlink had previously heavily promoted; its risk management network will no longer operate as an independent review node, with such independent checks now provided by optional validators. This means that users who have not added any validators currently rely on a single validation network, whereas previously they relied on two. Existing Chainlink users have been automatically migrated to the new version, but the company has not disclosed which institutions are using the new validators, only stating that Aave and Maple have begun adopting other features of the upgrade.

first_img Wyoming will migrate the FRNT stablecoin from LayerZero to Chainlink CCIP

The Wyoming Stablecoin Committee has migrated its issued Frontier Stable Token (FRNT) from LayerZero to Chainlink's cross-chain interoperability protocol CCIP, and will completely discontinue the LayerZero token implementation after completing a comprehensive security review. CCIP will serve as the sole cross-chain infrastructure for FRNT under a multi-year contract. This is the first time a U.S. government entity has publicly changed blockchain infrastructure for security reasons, and FRNT is currently the only stablecoin issued by a U.S. public institution, fully backed by fiat reserves, with reserve earnings used to support the state's school foundation projects. The token has been deployed on chains such as Ethereum, Base, and Avalanche, with a current market cap of less than $1 million.This decision was announced four months after the Kelp DAO bridge based on LayerZero was attacked, resulting in the theft of approximately 116,500 rsETH (worth about $292 million at the time), an incident that triggered a wave of industry security reviews and migrations. To date, nearly $15 billion in related assets have migrated from LayerZero to Chainlink, with early movers including Kelp, Solv Protocol, Re, and Kraken. Subsequently, BitGo chose CCIP and completed a migration of approximately $7.7 billion in wrapped Bitcoin, bringing the total to the current level. According to a case study by LayerZero in January of this year, Wyoming had previously operated its own decentralized validation network and controlled validation and compliance functions.
