Band Goes Live on Kasplex Mainnet: Powering On-Chain Data for Fervent by Zealous Swap

We are thrilled to announce that Band has gone live on Kasplex, the official Layer 2 built on Kaspa, marking a major milestone in bringing decentralized data solutions to one of the fastest-growing ecosystems in the blockchain space. This integration enables Fervent, a DeFi protocol developed by Zealous Swap, to securely access real-world data through Band’s decentralized oracle network, powering reliable on-chain trading and yield operations on Kasplex.

Band Integration on Kasplex

Kasplex is the official Layer 2 scaling solution for the Kaspa network, designed to deliver high-performance and modular infrastructure for DeFi applications. Built on Kaspa’s innovative UTXO-based architecture, Kasplex offers unmatched scalability, lightning-fast throughput, and extremely low transaction fees. Its modular framework allows for seamless integration with the Band Data Layer, ensuring that protocols on Kasplex can easily access accurate and tamper-proof data feeds. Notably, $KAS is now live on Kasplex, unlocking new DeFi possibilities powered by secure data solutions from Band, with more symbols to be added in the near future.

Fervent by Zealous Swap: Band's First Use Case on Kasplex

Fervent, developed by Zealous Swap, is the first DeFi protocol on Kasplex to integrate Band data feeds. It serves as a decentralized trading and yield platform that relies on precise, on-chain price data to operate efficiently and securely. With Band Price Feeds, Fervent enhances its core functionalities, including:

  • Liquidation, enabling users to earn yield with accurate market valuations.
  • Risk management systems, supported by reliable and decentralized on-chain asset pricing.

This collaboration sets a new standard for data integrity and transparency across Kasplex’s emerging DeFi ecosystem.

Technical Integration Overview

Technical Integration Overview

Band’s integration with Kasplex introduces a robust, fully decentralized oracle flow that connects off-chain data to on-chain applications:

  1. Data Request: BandChain validators request real-time asset price data from trusted data sources such as CoinGecko, CoinMarketCap, and Kraken.
  2. Aggregation & Validation: Validators aggregate, cross-verify, and reach consensus on the data from multiple sources.
  3. Data Relay: The verified data feed is relayed from BandChain to Kasplex smart contracts via Band's Standard Dataset.
  4. Data Access: Fervent reads the validated price data directly from Band’s Standard Reference Contract deployed on Kasplex.
  5. Price Utilization: The contract continuously supplies Fervent with fresh and accurate price data for on-chain operations.

This setup allows scalable support for custom data requests as Kasplex’s ecosystem grows, empowering developers to integrate diverse data types with ease.

Benefits and Impact

This integration means different things to different participants, but what we all share is the foundation of a trustless, reliable, and secure data infrastructure now available across the Kasplex ecosystem.Here’s the breakdown:

  • For Kasplex Developers: Seamless access to decentralized and verifiable data feeds, enabling DeFi protocols, DEXs, and lending platforms to launch faster and with stronger data reliability.
  • For Fervent Users: A new level of reliability and transparency for trading and yield operations. Band’s oracle infrastructure removes single points of failure and guarantees consistent price accuracy.
  • For the Kaspa Ecosystem: Strengthened DeFi foundations through a trusted data layer that unlocks the potential for more complex and innovative financial applications.

Developers can now build on Kasplex using Band Data Feeds to bring secure, real-world data directly into their smart contracts. Band is already deployed on Kasplex and ready for everyone to build on top of, creating your dream applications. Start building with Band on Kasplex today.

Next Steps and Future Roadmap

Band will continue expanding oracle support across more Kasplex-based protocols, with plans to introduce custom data feeds tailored to Kaspa-native DeFi projects. Further collaboration with the Zealous Swap team will deepen integration and scalability, paving the way for more partnerships within the Kaspa ecosystem.Band remains committed to powering the next generation of decentralized applications through secure, scalable, and verifiable data infrastructure. With the launch of Band Oracle on Kasplex Mainnet, developers can now build confidently with reliable access to real-world data, fueling the continued growth of the Kaspa DeFi ecosystem. This is not just another integration; it’s the open door to a new era of decentralization.
