The Ronin Network Adopts Chainlink’s Cross-Chain Interoperability Protocol (CCIP) to Secure Ronin Bridge

The Ronin network has officially adopted Chainlink's Cross-Chain Interoperability Protocol (CCIP) after receiving approval from its validators.

The Ronin Network has adopted Chainlink’s Cross-Chain Interoperability Protocol (CCIP) to enhance the security of its bridge, enabling seamless asset transfer between the Ronin chain and the Ethereum network.

After a three-phase selection process involving LayerZero, Axelar, and others, Chainlink’s CCIP emerged as the preferred solution following a proposal on the Ronin Network’s Discord channel. The decision was made in light of the urgent need to bolster the security of bridged assets.

Emphasizing security, the Ronin ecosystem validators highlighted specific qualities of Chainlink CCIP, including its transaction integrity property, which is achieved through multiple decentralized oracles and customizable security features.

Chainlink CCIP also boasts arbitrary messaging, programmable token transfers, and future-proof adaptability for developers seeking to innovate in cross-chain interoperability.

“Out of all the solutions available on the market, adopting Chainlink CCIP as Ronin’s canonical cross-chain infrastructure was an obvious choice, given the protocol’s unparalleled security features and reliability track record,” said Phuc Thai, Head Researcher at Sky Mavis, Axie Infinity’s developer.

“Beyond cross-chain interoperability, we are keen to work on integrating Chainlink’s suite of Oracle services that will serve as an important foundation for the next phase of DeFi growth on Ronin.”

With the integration of Chainlink’s CCIP, the Ronin Network gains advanced cross-chain security. Utilizing multiple Decentralized Oracle Networks (DONs) and an independent Risk Management Network, CCIP provides high-quality node operators, rate-limiting, and time-locked upgrades for optimal security.

Furthermore, the Ronin Network can leverage Chainlink’s off-chain data and compute solutions to support its developer ecosystem. All tokens on Ronin will undergo a user-triggered migration with the integration aiming to minimize user impact.

“All assets bridged via the existing Ronin Bridge will be upgraded to use CCIP for native cross-chain transfers. It will start initially with support for transfers between Ethereum and the Ronin Network,” a statement in the Ronin Discord reads.

“The expectation is for the full migration to happen over the next 2-3 months.”

The Ronin Network’s pursuit of a cross-chain security solution follows the recent attack on its bridge. As reported by BeInCrypto, the Ronin Bridge lost 3,996 ETH (then valued at $9.33 million) in early August to a hack. The incident adds to a string of attacks on the Ethereum sidechain, including another in 2022 where hackers accessed private keys to its validator nodes to pilfer an estimated $600 million.

“Axie/Ronin is a cursed project I swear – Ronin bridge $600 million hack March 2022 – Axie/Ronin co-founder $9.7 million hack February 2024 – Now this bridge incident,” ZachXBT remarked recently.

These attacks have raised eyebrows, but the Ronin Network isn’t alone in tapping Chainlink’s CCIP for enhanced protection. Notably, Hong Kong’s IDA Finance also integrated Chainlink’s Proof of Reserve (PoR) and CCIP to bolster the transparency and accessibility of its HKDA stablecoin, with CCIP securing cross-chain data and value transfers.

Other recent collaborations include Swiss cryptocurrency custody and trading firm Taurus, and Bedrock, a liquid restaking protocol. Bedrock’s integration of CCIP follows a significant exploit on September 26 involving its staked wrapped BTC token, uniBTC.

Sony’s Soneium also integrated Chainlink’s CCIP as its core infrastructure to support blockchain growth across multiple chains. These developments showcase how Chainlink’s industry-standard services continue to attract partnerships.
