Arc reached two milestones on September 16, 2026, launching its mainnet and joining Polygon’s Open Money Stack. The mainnet launch includes Chainlink services from day one, giving developers access to institutional-grade oracle infrastructure such as CCIP, Data Feeds, and Proof of Reserve.
The Polygon integration enables one-click movement of USDC across Ethereum and Solana, simplifying crosschain payments. Polygon described the collaboration as a step toward more unified onchain payment rails, while the broader crypto market continues to show mixed signals.
Arc is a Layer 1 blockchain developed by Circle and focused on DeFi applications. Chainlink’s oracle network connects smart contracts with real-world data, making it a key infrastructure partner for Arc’s early-stage ecosystem. According to market data cited in the coverage, Polygon’s price was stable with low 24-hour trading volume, while Arc’s trading volume remained absent and its price was listed at $0, reflecting its very early market presence.
Traders and developers are expected to monitor whether the integrations drive user adoption, transaction volume, and institutional interest. If activity increases, the partnerships could encourage further crosschain innovations and additional integrations across the Polygon and Arc ecosystems.
