Chainlink Connects CCT with SuperchainERC20 on Optimism

• Chainlink’s CCT now supports SuperchainERC20, enabling seamless cross-chain functionality for tokens like ASTR across Optimism’s ecosystem.
• Chainlink Labs joins the Global Synchronizer Foundation to help design institutional-grade interoperable blockchain infrastructure.

Chainlink’s cross-chain token standard, Cross‑Chain Token (CCT), has officially become compatible with SuperchainERC20, Optimism’s new token standard.

This integration was not just an announcement, it was demonstrated directly through real-world implementation: Astar Network’s ASTR token became the first token to run on the combination of the two standards, with its initial launch taking place over a Layer-2 network called Soneium.

Chainlink CCIP’s Cross-Chain Token (CCT) standard is now compatible with @Optimism’s SuperchainERC20, with its first deployment on @soneium via @AstarNetwork‘s token, ASTR.

What does this all mean? Simply put, ASTR can now make cross-chain transfers between networks that are part of Optimism’s Superchain ecosystem, without the hassle and without relying on vulnerable bridges.

Chainlink CCIP is the backbone of this process. If you think of it in everyday life, it’s like having a bank account that can be directly connected to a digital wallet, a neighboring country’s e-wallet, and even an ATM machine across continents—without having to go through a third party with hidden fees. Furthermore, Johann Eid, Chief Business Officer at Chainlink Labs, also stated:

“As the first token to adopt the CCT standard on Soneium, ASTR creates the foundation for how Optimism’s SuperchainERC20 tokens can become CCT-compatible, reinforcing how Chainlink CCIP enables secure cross-chain interoperability across leading ecosystems.”

Chainlink’s Bigger Vision for Blockchain Interoperability

This integration is a significant moment not only for Astar, but also for the wider ecosystem. By combining the speed and security of Chainlink CCIP with the flexibility of the SuperchainERC20 standard, ASTR is now strategically positioned as a bridge between networks. Soneium itself is a new Layer-2 built on the OP Stack, adding a variety of options for projects that want to build cross-chain but still practical.

However, Chainlink’s steps don’t stop here. On the other hand, CNF previously reported that Chainlink Labs has joined the Global Synchronizer Foundation. They want to shape the future of blockchain applications that can be accessed more easily by large institutions.

Chainlink’s technology has also been used by big names like UBS, MAS (Singapore), and SBI in their efforts to tokenize traditional funds into blockchain-based digital assets.

Interestingly, just a few days before the announcement about ASTR, Chainlink was also involved in the pilot program of Hong Kong’s central bank digital currency (CBDC). In that project, the CCIP protocol was used to facilitate the exchange between e-HKD and the Australian dollar stablecoin—in real-time.

This project involved big companies like Visa, ANZ, Fidelity International, and ChinaAMC, and showed how Chainlink was able to bridge permissioned and permissionless blockchains in one seamless system.

Speaking of cross-chain, it’s also worth remembering that last May, Chainlink officially launched CCIP on the Solana network. This became the first non-EVM network to integrate with CCIP, opening up new access for Solana developers to use Data Feeds, Data Streams, and other cross-chain features.

However, all of this is not just a technology parade. The implementation of ASTR on Soneium is a kind of “live demo” that Chainlink and Optimism can work together not just on paper, but actually work on a real network.

Meanwhile, as of press time, LINK is swapped hands at about $15.51, up 3.52% over the last 24 hours and 10.17% over the last 7 days.
