Band x Arc Testnet: Powering the Future of Stablecoin Chain Through Open-Source and Multi-Oracle Innovation
We are thrilled to announce that Band has officially integrated with Arc, marking another major milestone in expanding decentralized data accessibility across modular blockchain ecosystems.
We are thrilled to announce that Band has officially integrated with Arc, marking another major milestone in expanding decentralized data accessibility across modular blockchain ecosystems. This integration enables Band to deliver USDC/USD price feeds directly to the Arc testnet, bringing reliable, real-world financial data to developers building next-generation DeFi and Web3 applications.
Band Integration on Arc
Arc is an open source, next-generation modular blockchain focused on interoperability, liquidity routing, and performance. It provides a high-throughput execution layer designed for seamless cross-chain composability, allowing developers to connect assets and applications across diverse ecosystems.
Through this integration, Band’s decentralized oracle network now supplies verifiable $USDC price data to the Arc testnet. This empowers developers to build DeFi primitives, stablecoin-based protocols/ applications, and RWAs that rely on accurate, tamper-proof on-chain data, a critical foundation for trustless financial operations.
Band’s flexible oracle architecture ensures that Arc developers can easily request, validate, and consume price feeds with minimal latency and full transparency. The integration serves as the groundwork for expanding to additional assets and datasets as Arc moves toward mainnet.
Technical Integration Overview
Band’s integration with Arc leverages its Cross-Chain Oracle Framework, ensuring a secure and efficient data relay between BandChain and Arc’s modular infrastructure.
How It Works:
- Data Request: BandChain validators query real-time USDC price data from trusted sources such as CoinGecko, CoinMarketCap, and centralized exchanges.
- Aggregation & Consensus: Validators aggregate the data and reach consensus using BandChain’s delegated proof-of-stake mechanism.
- Data Relay: The verified data is relayed securely to Arc’s testnet.
- Data Access: Arc-based smart contracts can directly fetch the validated price from Band’s standard reference contract deployed on the testnet.
- Usage: Developers can integrate this verified USDC feed into their dApps, powering lending, trading, and yield functionalities with on-chain accuracy.
This technical flow ensures that every price update is verifiable, decentralized, and traceable on-chain, building trust for DeFi builders on Arc.
Benefits and Impact
This integration represents more than just another data feed. It embodies a step toward a multi-oracle, open-standard future for Web3. By joining Arc’s ecosystem, Band reinforces the principle that no single oracle should dominate the flow of on-chain data. Instead, multiple oracle providers can coexist to ensure the highest levels of reliability, transparency, and decentralization. In this multi-oracle architecture, Band serves as a trust-minimized, community-driven alternative to existing oracle providers, offering developers and users an open and verifiable data layer that strengthens the entire ecosystem.
- For Builders: Band’s integration empowers developers with true freedom of choice. Builders can now select the oracle network that best fits their design goals, from speed and decentralization to data diversity, supporting innovation without dependence on a single source of truth.
- For DeFi Protocols: A multi-oracle setup creates stronger fault tolerance and data redundancy. By having multiple independent oracle networks, protocols remain protected against data discrepancies, manipulation, or downtime, ensuring stability and confidence even during market volatility.
- For Users: Multiple oracle providers mean safer funds and fairer markets. The reduced risk of oracle manipulation enhances trust in DeFi protocols, keeping users’ assets secure while maintaining transparency across the ecosystem.
- For the Ecosystem: Band’s participation also champions the open source movement, supporting open standards and interoperable systems that invite contribution, collaboration, and shared progress. By promoting open and verifiable infrastructure, we collectively build a more transparent, inclusive, and sustainable DeFi future.
Together, Band and Arc are paving the way for a truly decentralized, open, and resilient data layer, one that empowers developers, safeguards users, and strengthens the foundation of the entire Web3 ecosystem.
Next Steps and Future Roadmap
Following the successful deployment on Arc Testnet, Band plans to expand support to mainnet, integrating more asset pairs and data services. Future collaborations will explore custom data feeds, cross-chain relays, and real-time price streams tailored to Arc’s liquidity infrastructure. Band remains committed to powering the next era of decentralized applications through scalable, secure, and verifiable data infrastructure. Together with Arc, we’re one step closer to a truly connected and data-driven Web3 future.
