Nethermind leaves LayerZero verifier role for Chainlink

Ethereum engineering firm Nethermind announced on August 19, 2026 that it has ended its role as a LayerZero decentralized verifier and migrated to Chainlink's Cross-Chain Interoperability Protocol following an extensive but unpublished review. The move adds Nethermind, which supports over 16,000 Ethereum validators and $5 billion in delegated assets, to a wave of high-profile migrations from LayerZero to Chainlink totaling nearly $15 billion in value, including BitGo's $7.3 billion WBTC ecosystem and Wyoming's state-issued FRNT stablecoin. The migrations follow an April 2026 exploit of Kelp DAO's LayerZero bridge that drained $290 million through a forged message and single-verifier configuration, prompting LayerZero to mandate multi-verifier setups while Wyoming cited disclosure and security concerns in its switch.

Nethermind Chainlink node operations

• ▪Nethermind said the decision to join Chainlink followed an extensive review, but Nethermind did not publish the review or explain which technical and operational factors determined the result.
• ▪Nethermind employs more than 200 people across client development, cryptography, blockchain security, formal verification, and institutional infrastructure.
• ▪Nethermind will concentrate its cross-chain work on Chainlink's Cross-Chain Interoperability Protocol.
• ▪Nethermind's software supports more than 16,000 Ethereum validators and over $5 billion in delegated assets.
• ▪Neither Nethermind nor Chainlink disclosed the financial terms of the arrangement between Nethermind and Chainlink.
• ▪Nethermind will help operate Chainlink's network while supplying engineering tools, infrastructure services, and integration support to blockchain developers.
• ▪Nethermind announced on August 19, 2026 that Nethermind had migrated away from its decentralized verifier network operations and joined Chainlink as a node operator and strategic technology provider.

KelpDAO rsETH bridge exploit

• ▪The April 18, 2026 attack on Kelp DAO's bridge involved a forged cross-chain message and a single-verifier configuration.
• ▪Kelp DAO said LayerZero had known about Kelp DAO's 1-of-1 verifier arrangement and had previously treated the configuration as secure.
• ▪Hackers drained 116,500 rsETH, worth about $290 million at the time, from Kelp DAO's LayerZero-powered bridge on April 18, 2026.
• ▪The attacker in the Kelp DAO bridge exploit created unbacked rsETH and later placed much of it into Aave lending positions to borrow wrapped Ether, spreading losses beyond the bridge itself.
• ▪LayerZero CEO Bryan Pellegrino said LayerZero had not recommended the single-verifier configuration for production.
• ▪LayerZero CEO Bryan Pellegrino said the Kelp DAO protocol initially used a multi-verifier setup involving LayerZero Labs and Google before changing it to a single verifier.
• ▪Kelp DAO announced an rsETH migration to Chainlink in May 2026 while disputing LayerZero's account of the security setup.

Cross-chain verifier network models

• ▪Within LayerZero, decentralized verifier networks independently check whether messages sent between blockchains are genuine and unchanged.
• ▪In LayerZero's system, once a message leaves its source blockchain, the selected verifiers confirm its digital fingerprint before the message can be committed and executed on another network.
• ▪Chainlink says its CCIP system uses independent node operators, transaction limits and a separate risk-management network to monitor cross-chain activity.
• ▪LayerZero's documentation describes each DVN as a combination of smart contracts and off-chain systems.
• ▪Applications using LayerZero can choose which DVNs verify their messages and set the number of approvals needed before a transaction proceeds.

BitGo WBTC provider switch

• ▪Aave adopted CCIP in July 2026 as the default system for cross-chain functions across its app and Stable Vaults.
• ▪BitGo selected Chainlink in August 2026 as the exclusive cross-chain provider for Wrapped Bitcoin, replacing LayerZero across a WBTC ecosystem then valued at about $7.3 billion.
• ▪The BitGo WBTC announcement brought the value covered by publicly disclosed LayerZero-to-Chainlink migrations to nearly $15 billion.
• ▪Aave expanded the CCIP integration to deposits, withdrawals, vault rebalancing, and asset movements.

Wyoming FRNT migration review

• ▪The Wyoming Stable Token Commission said on August 18, 2026 that the commission had completed its migration from LayerZero to Chainlink following a state security review.
• ▪FRNT reserve income supports Wyoming's School Foundation Program.
• ▪The Wyoming security review was not released publicly, leaving its full criteria and technical findings unavailable.
• ▪The Wyoming Stable Token Commission named disclosure practices and operational security among its concerns about LayerZero.
• ▪Wyoming's Frontier Stable Token (FRNT) is issued by a U.S. public entity and is available on eight blockchains, including Ethereum, Solana, Base, Arbitrum, and Avalanche.
• ▪Wyoming Stable Token Commission Executive Director Anthony Apollo said CCIP was the only system assessed by the state that met Wyoming's security and reliability requirements across the board.
• ▪Wyoming holds FRNT reserves in cash and short-term U.S. Treasury securities.

Perspective of LayerZero

• ▪LayerZero attributed the Kelp DAO incident to a compromised verifier rather than a flaw in its core messaging protocol.
• ▪A LayerZero spokesperson said LayerZero had strengthened its security approach in recent months but did not address the Wyoming commission's specific disclosure concerns.

Perspective of Wyoming Stable Token Commission

• ▪Wyoming Stable Token Commission Executive Director Anthony Apollo said CCIP was the only system assessed by the state that met Wyoming's security and reliability requirements across the board.
