Do you trust that major financial institutions using blockchain will improve overall financial security?
Circle has launched the Arc mainnet, a permissioned layer-1 blockchain designed for institutional use, with Chainlink deploying its infrastructure services. These tools include Data Feeds, Data Streams, and the Cross-Chain Interoperability Protocol (CCIP).
Why it matters
Arc allows institutions to operate on a blockchain without the volatility associated with holding native tokens, as all gas fees are settled in USDC. This deployment brings standardized oracle data and cross-chain messaging into a regulated, permissioned environment.
Chainlink CCIP is live on over 50 chains, expanding to the Arc mainnet which uses USDC for gas payments. While the network is fully launched, the throughput capacity and specific latency benchmarks for these institutional feeds are not yet public.
The players
Circle
A financial technology firm that developed the USD Coin stablecoin and the Arc permissioned blockchain infrastructure.
Chainlink
A decentralized oracle network provider that connects external data to blockchain smart contracts across numerous chains.
ICE
The Intercontinental Exchange, a financial services holding company that operates the New York Stock Exchange and serves as an Arc validator.
BlackRock
A global investment management firm that acts as a validator for the Arc blockchain network.
The details
Arc functions as a permissioned layer-1 blockchain—a foundational network that supports its own ecosystem—built by Circle to cater to institutional requirements. Chainlink provides data feeds, which deliver real-time financial data to smart contracts, and CCIP, a messaging protocol that allows different blockchains to exchange data and value. MOVA Chain also integrated CCIP to facilitate stablecoin and decentralized finance (DeFi) messaging.
Timeline
July 2026: MOVA Chain adopted the CCIP protocol.
September 9, 2026: Chainlink deployed Data Feeds to the Arc mainnet.
September 15, 2026: Chainlink launched Data Streams on the Arc mainnet.
September 16, 2026: The Arc mainnet officially launched alongside the activation of Chainlink CCIP.
The Tech Race
This deployment signals a move toward standardizing institutional blockchain infrastructure by porting established oracle tools like CCIP into permissioned environments. It follows the broader industry trend of building closed-loop networks that bridge traditional finance entities like BlackRock and ICE with blockchain-native settlement layers.
Institutional users and financial firms participating in the Arc ecosystem will now use USDC to settle gas fees rather than volatile native assets. Developers should note that this environment restricts participants to permissioned nodes, requiring direct integration with validators like ICE or BlackRock for network access.
The takeaway
The deployment of Chainlink on Arc bridges the gap between traditional financial institutional systems and distributed ledger technology. Observers should track the adoption rate of institutional participants moving assets onto the Arc mainnet as a metric for the viability of permissioned layer-1 networks.
