Chainlink has expanded its core services, including Data Feeds, Data Streams, and the Cross-Chain Interoperability Protocol (CCIP), to two new blockchain networks: Arc, Circle’s institutional layer-1 blockchain, and MOVA Chain, a network focused on decentralized finance (DeFi).
This expansion marks a significant step in providing institutional-grade infrastructure and enhancing cross-chain communication. Arc’s mainnet launched on September 16, 2026, with Chainlink’s services integrated prior to its activation. Chainlink’s Data Feeds went live on September 9, followed by Data Streams on September 15, offering crucial oracle coverage and low-latency market data. CCIP, Chainlink’s cross-chain messaging protocol, was activated on Arc’s mainnet on September 16, aligning with the network’s launch.
Arc is designed as a permissioned layer-1 blockchain for institutional use, featuring a validator network that includes major financial entities such as BlackRock, Visa, Mastercard, DTCC, and ICE. A notable feature of Arc is that gas fees are paid in USDC, simplifying operations for participants by removing the need to manage volatile native assets.
On MOVA Chain, Chainlink’s CCIP went live in July 2026. This integration is set to bolster MOVA Chain’s capabilities in stablecoins and DeFi applications by providing secure cross-chain messaging. By adopting CCIP, MOVA Chain gains immediate connectivity to a broader ecosystem spanning over 50 chains, bypassing the need for custom bridging solutions.
Chainlink’s strategic expansion to these networks is part of a broader initiative to bolster blockchain interoperability and facilitate institutional adoption. Earlier in 2026, Chainlink expanded CCIP to MegaETH and World Chain, with the Chainlink Runtime Environment (CRE) going live on World Chain in February. Chainlink had previously tested its services on Arc’s testnet before the mainnet launch, allowing developers to build and test applications in a pre-production environment.
The integration on Arc, with its institutional backing and the use of USDC for gas fees, underscores a trend towards enterprise-grade blockchain solutions. For MOVA Chain, the adoption of CCIP strengthens its position within the DeFi landscape by enabling seamless cross-chain communication. The growing number of chains supported by CCIP, now exceeding 50, enhances the overall utility and network effect of Chainlink’s interoperability protocol, benefiting all connected projects.
Why This Matters
The materials describe a narrow update: Chainlink has integrated its core services, including Data Feeds, Data Streams, and the Cross-Chain Interoperability Protocol (CCIP), onto Arc, Circle’s institutional layer-1 blockchain, and MOVA Chain, a DeFi-focused network. Chainlink’s expansion to Arc and MOVA Chain accelerates institutional blockchain adoption by providing core infrastructure and cross-chain interoperability.
Broader Context
Source materials place the factual news in this context: Chainlink has extended its core services to two new networks: Arc, Circle’s institutional layer-1 blockchain, and MOVA Chain, a DeFi-focused network that adopted Chainlink’s Cross-Chain Interoperability Protocol in July 2026.
