Chainlink has introduced CCIP 2.0, an upgraded cross-chain interoperability protocol designed to help organizations strengthen security when transferring assets across different blockchains. This launch comes five months after a major exploit on LayerZero’s bridge solution resulted in $292 million in losses for Kelp DAO.
Enhanced security for cross-chain transactions
Chainlink is known as a decentralized oracle provider, supplying blockchains with external data such as market prices to support decentralized finance applications. Its Cross-Chain Interoperability Protocol (CCIP) expands those capabilities, enabling digital assets and data to move across separate blockchain ecosystems.
To achieve secure bridging, transactions must be validated before assets can move between blockchains. If validators are compromised, attackers can extract value. This was demonstrated in April, when North Korea-linked hackers exploited LayerZero’s system, draining a large amount of rsETH from Kelp DAO. The incident drew scrutiny over the bridge’s reliance on a single validator.
LayerZero claimed Kelp DAO should have adopted multiple validators for added security. Kelp DAO responded that LayerZero staff had reviewed their setup without raising concerns.
With CCIP 2.0, Chainlink users can now select additional independent validators or run their own, on top of Chainlink’s core pool of 16 autonomous node operators. This extra layer offers organizations more control and resilience against attacks.
“Traditional bridge solutions have hemorrhaged billions through vulnerable infrastructure. The new framework enables users to implement robust, customizable security layers,” said Johann Eid, chief business officer at Chainlink Labs.
Existing CCIP implementations will remain functional and do not require modifications.

Chainlink expands through Swift partnership
Alongside CCIP 2.0, Chainlink announced a new connectivity solution for the global banking sector. The company’s technology will allow financial institutions to interface directly with Swift’s blockchain-based distributed ledger while maintaining sole control over their transaction authorization credentials.
Sergey Nazarov, Chainlink’s CEO, expressed excitement for supporting Swift’s infrastructure. Under Swift’s model, tokenized deposits remain on banks’ balance sheets, with ultimate settlement still relying on traditional systems like real-time gross settlement networks.

Global banks join testing phase
Seventeen major financial institutions from six continents are now commencing pilot programs to test the new setup. This initiative features established banks including HSBC, Citi, UBS, and Wells Fargo.
Swift’s global network already supports connections across over 200 jurisdictions, serving thousands of banks and financial entities worldwide.

Amid these developments, LINK, Chainlink’s native cryptocurrency, hovered around $15.20. Market analyst Albie suggested the altcoin is “ready for $100+” following what was described as a prolonged consolidation period.
LINK is trading near $15.20, with observers citing the network’s latest upgrade and banking collaboration as potential drivers for renewed momentum.
