Spark is excited to announce the launch of its Mainnet Beta—marking the debut of the first on-chain order book exchange on Ethereum, powered by the FuelVM.

This launch is the culmination of two years of focused development, delivering a decentralized, permissionless trading experience tailored for professional and institutional traders alike. And this is just the beginning: expect continuous enhancements and updates in the coming days and weeks as we refine and expand our platform.

Why Spark?

Our mission is clear: to liberate the trading experience from the limitations of centralized systems and empower users with full control over their assets. By integrating on-chain Central Limit Order Books (CLOBs) with Fuel’s modular architecture, Spark introduces a more transparent, efficient, and secure way to trade on Ethereum.

Built for traders who value superior price discovery and minimal slippage, Spark’s on-chain CLOB offers next-gen trading mechanisms that set a new standard in decentralized finance. From seamless user experiences to advanced features that support high-frequency trading, Spark is designed to redefine the trading experience with precision and control at its core.

Fueling Spark’s Vision: Powered by Fuel’s Modular Architecture

Fuel’s state-minimized, high-throughput design has been instrumental in bringing Spark to life. By leveraging Fuel’s modular rollup architecture, Spark achieves unmatched scalability while maintaining transparency, security, and self-custody for traders.

Fuel’s parallel execution and low transaction fees ensure that Spark operates efficiently, even at high volumes, while its integration of Ethereum-grade data availability guarantees the security and verifiability of all on-chain transactions.
