Intents are a mechanism for encoding desires and constraints within the blockchain ecosystem. They represent a significant leap towards a more intuitive and user-centric model of interaction. By codifying user preferences into executable conditions, intents bridge the gap between abstract contractual language and tangible system behavior. This translation from human intention to machine-readable code empowers users to shape the digital landscape according to their own needs, signaling a future where technology adapts to us, not the other way around. The promise of intents lies in their ability to make blockchain technology more approachable and aligned with individual expectations, bringing in a new era of personalized digital experiences.

Understanding intents can be tricky, but the concept is increasingly tangible in everyday applications. Take Google Flights as a prime example. It's an intent interface where users set their travel dates and preferences with ease. They can specify not just when they want to fly, but also how they like to travel—be it fewer stops or flexible dates for the best deals. Similarly, in the blockchain realm, a user might express their intent to trade ETH for USDC, specifying a preference for high security and then letting the intent engine figure out which zk-rollup offers the best price for the transaction. Onchain, CowSwap's request-for-quote system and Across' bridge are practical examples. They leverage networks of relayers to fulfill users' “intents” for optimal pricing and secure bridging, respectively. These examples illustrate how intents are shaping user interactions with blockchain, making complex decisions more user-friendly.

Still, intents’ reliance on specific relayer networks has stifled broader composability. One protocol leading the charge in fully-integrated, composable intent infrastructure is Brink. A user can interact with Brink’s intent interface that will then publish the intent to the pool that can be filled by the decentralized network of solvers from projects like Enso Finance or Brink’s own solver network. This framework is being adopted across the space such as the recent announcement of Across V3. Across is opening its relayer network to third-party applications. This move hints at a future where intents can be more universally applied to onchain interactions. These protocols will look to enhance their composability across the network. The end goal is a universally composable intent engine. This engine’s interface wouldn’t be tied to any one execution environment, promising users a seamless experience tailored to their preferences, and projects like Anoma are approaching intents as the linchpin in aligning economic behavior with individual desires.

Chris Goes, the co-founder of Anoma, has reignited interest in the project's ambitious intent interface. He recently shared insights on the Ethereum research forum, outlining Anoma's plan to integrate its universal intent machine with Ethereum. This move underscores a commitment to a more fluid and user-responsive blockchain ecosystem. Anoma's mission paper, 'Undefining Money,' provides a philosophical backdrop for their long-haul vision. It emphasizes the need for blockchain systems that not only understand but also prioritize user preferences and constraints.

Many existing protocols are now adopting intent-based architectures, which are characterized by duality, universality, and composability. These features point to a future where users can navigate blockchain spaces with greater ease and assurance. Anoma's four key affordances—permissionless intent infrastructure, intent-level composability, information flow control, and heterogeneous trust—are set to redefine user interaction. They hinge on three innovative mechanisms: the resource machine, the heterogeneous trust node architecture, and explicit service commitment languages. Together, these elements aim to create a blockchain environment that is both responsive to user needs and adaptable to various trust models. The Anoma team is rolling out their vision in stages, with the first wave of intent machines already in the pipeline. These machines are designed to be execution-environment agnostic, ensuring that users get a smooth and tailored experience. Anoma has opened the floor for feedback, inviting the Ethereum community to review and interact with their system.

Put simply, intents are poised to revolutionize blockchain interaction, making the user's experience more intuitive and tailored. By blurring the boundaries between disparate execution environments, they promise to deliver not just functionality, but also the best possible outcomes based on personal preferences. The journey is long, and turning these ambitious blueprints into a working reality will be the ultimate challenge.
