This article examines application-controlled execution (ACE), focusing on how it allows applications to dictate transaction order, specifically through a mechanism called cancel prioritization. It analyzes different implementation designs and their trade-offs, highlighting Hyperliquid's approach as a leading example. The discussion also addresses potential challenges like block-building complexity and composability issues.

Hyperliquid is a decentralized exchange operating on its own Layer-1 blockchain, HyperEVM, utilizing a fully on-chain order book model to enhance performance and scalability. It features a unique architecture that combines two components, HyperCore and HyperEVM, allowing for seamless integration and real-time liquidity access. Users can engage in vaults for trading strategies and participate in governance through Hyperliquid Improvement Proposals (HIPs).

Hyperliquid's EVM-compatible layer-1 blockchain, HyperEVM, is gaining traction with increasing transaction volumes and application development since its February launch. Key updates like the CoreWriter have enhanced integration with HyperCore, positioning HyperEVM as a significant component of Hyperliquid's DeFi ecosystem, despite initial limitations in tooling and incentives.

Native USDC and CCTP V2 are set to be integrated into Hyperliquid, enhancing its decentralized finance capabilities. This development will facilitate USDC deposits on HyperCore and allow for seamless cross-chain transactions, making it a foundational asset for various use cases within the ecosystem.
