We’re excited to announce that stake.link has integrated Chainlink CCIP—the industry standard for secure cross-chain interoperability—across Ethereum and Arbitrum mainnets. We’re leveraging CCIP’s Simplified Token Transfer capabilities to facilitate cross-chain LINK Staking and native protocol asset management, enabling users to bridge wrapped staked LINK (wstLINK) as well as the stake.link protocol token SDL to Arbitrum. For the first time, users are able to gain exposure to LINK Staking outside of Ethereum mainnet.

We selected CCIP as our preferred interoperability solution because Chainlink has the most proven track record of maintaining the highest standard of security and reliability in the Web3 industry. Furthermore, CCIP is backed by the Risk Management Network—a separate, independent network that continually monitors and verifies cross-chain operations for suspicious activity. This additional layer of security is particularly important given historical industry exploits and the billions in user funds lost due to insecure and unreliable cross-chain infrastructure.

stake.link is the first-of-its-kind and sole Liquid Staking Protocol for the Chainlink  Ecosystem comprising 15 of the most performant node operators and validators not just in the Chainlink Ecosystem, but across all of Web3.

Leveraging CCIP to enable protocol interoperability between Ethereum and Arbitrum will enable users to access our growing suite of products in a faster and lower fee environment while preserving a familiar user experience. Now, users are able to access stake.link services natively on Arbitrum while Chainlink’s CCIP and Automation handle the rest.

In order to help secure our cross-chain liquid staking protocol, we needed access to a highly secure and reliable interoperability solution. After reviewing various solutions, we integrated Chainlink CCIP because it provides a multitude of important benefits and features, such as:

• Time-tested security and reliability—CCIP’s consensus and interoperability layer is powered by Chainlink decentralized oracle networks, which have already secured tens of billions of dollars for smart contracts and enabled over $9 trillion in onchain transaction value. CCIP also features additional layers of protection and reliability via the Risk Management Network and Smart Execution.

• Secure Token Transfers—CCIP features a plug-and-play solution consisting of audited token pool contracts that handle the complexity of burning and minting or locking and minting tokens across chains. CCIP Token Transfers also have additional security features like Rate Limits, and enable ecosystem partners to easily build new capabilities around a supported token via a single CCIP interface.

• Programmable Token Transfers—CCIP messages are programmable, meaning token transfers and arbitrary data transfers can be one atomic transaction. This enables instructions to be passed in the data payload regarding what to do with the tokens once they arrive at the destination chain.

• Future-proof—CCIP is built to support continuous updates, such as the integration of new blockchains, the introduction of advanced functionalities, and the addition of other defense-in-depth approaches to security. Thus,  integrating CCIP eliminates future switching costs should new cross-chain functionalities be required.

“By using Chainlink CCIP, it allows us to focus on developing cutting-edge use cases that bring best-in-class security and simple experience to end users. Rather than needing to lock and choose where we deploy, we now have the ability to bring our first-of-its-kind platform to where the users want it no matter the chain.”  – Jonny Huxtable, CEO of LinkPool
