DeFi's Outcome Engine** ---------------------------------------- Haiku is not just a DeFi protocol. It is a high-performance intent-solver and outcome engine. Rather than forcing users, or developers, to puzzle through endless fragmented steps, Haiku enables anyone to define a desired DeFi goal… The system then translates that goal into an optimised, atomic execution path, delivering best-in-class results in a single transaction. This radically simplifies DeFi, moving beyond the limitations of smart order routers or traditional aggregators. **Meet the Haiku API and Widget** --------------------------------- The Haiku API empowers builders, teams, and power-users with a robust, intent-based interface for DeFi. Instead of manual step-by-step transactions, partners and users define an end state, then let Haiku take care of the rest. The widget extends this functionality to any UI or dApp, enabling partners to bake advanced outcomes directly into their user journey. ![](https://storage.googleapis.com/papyrus_images/a7211b9062733a15f05d90236805df34.png) **The Power of Intent-Solving for DeFi** ---------------------------------------- Traditional DeFi aggregators and smart order routers operate like GPS systems… they find the best path for a single journey you've already mapped out. But what if you could describe where you want to end up and let the system figure out not just the route, but the entire strategy? That's the fundamental shift intent-solvers bring to DeFi.

Want to rebalance your portfolio from stablecoins to blue-chip tokens across three chains? You're looking at 8-12 separate transactions: approve tokens, bridge assets, swap on multiple protocols, handle slippage on each step, and pray nothing fails halfway through. Each step introduces risk, gas costs, and potential MEV exploitation. Traditional aggregators can optimise individual swaps, but they can't understand or execute complex, multi-step financial goals. They're reactive tools that require you to break down sophisticated strategies into primitive operations. ![](https://storage.googleapis.com/papyrus_images/a457250c57d983ff5cad3883f4174951.png) ### Haiku's Three-Layer Architecture: Beyond Simple Routing Haiku's intent-solving engine represents a paradigm shift from "execute transactions" to "achieve outcomes." Here's how each layer works: 1. **Intent Structuring Layer:** This layer translates your goal (e.g. you want to rebalance your portfolio to 40% ETH, 30% BTC, 30% stables) into elegant machine logic. It maps your current portfolio against your target, finds where your assets live, analyzes liquidity, and respects your constraints like slippage and gas limits to create a comprehensive execution plan. 2. **Convex Optimizer:** While traditional routers optimize for one variable, like price, Haiku's optimizer solves across multiple dimensions at once. It considers price impact, gas efficiency, and capital efficiency to find a genuinely optimal solution, not just a "good enough" route. This might mean identifying a single large liquidity operation that achieves your goal with significantly less slippage than five separate swaps. 3. **Atomic Execution Engine:** This solves one of DeFi's biggest UX nightmares: partial execution. Your entire intent, whether it involves two operations or twenty, is packaged into a single, indivisible transaction. Either your complete goal is achieved, or nothing happens at all. This guarantees you never get stuck in a weird intermediate state or waste gas on a failed strategy, ensuring predictable outcomes every time. ![](https://storage.googleapis.com/papyrus_images/1d94744c31c53efc1bc1b459daf74cad.png) This three-layer architecture creates something unique in DeFi: outcome predictability at scale. Traditional aggregators can tell you the best swap rate right now, Haiku can guarantee you'll achieve your portfolio target or pay nothing. This is a fundamentally different value proposition that transforms complex DeFi strategies from risky manual processes into reliable, one-click outcomes. The result? DeFi finally becomes accessible to users who want sophisticated financial outcomes. **Real-World Applications to Level Up Your UX** ----------------------------------------------- This architecture unlocks powerful, real-world applications that level up the UX you can provide your users: * **Portfolio Rebalancing:** Let users rebalance across dozens of tokens and multiple chains in one click, responding instantly to market events without navigating countless interfaces. * **Complex Yield & Vault Onboarding:** Allow users to zap any basket of assets into structured positions across different protocols and chains, removing friction and increasing TVL for vault partners. * **Web3 App Onboarding:** Help new users onboard by converting their existing assets/primitives into the required assets instantly, without them needing to understand swaps or bridges. * **Automated Trading & Arbitrage:** Enable bots and agents to execute multi-leg arbitrage, hedge positions, or rebalance collateral with guaranteed, atomic transactions that boost reliability and efficiency. * **Embedded Smart Workflows:** Introduce new flows like recurring rebalancing or conditional execution based on market triggers, keeping users engaged with "set-and-forget" routines. ![](https://storage.googleapis.com/papyrus_images/232b39201d43b885b1f1b827de7ca462.png) **How the Haiku Intent-Solver API Works** ----------------------------------------- The Haiku API suite provides endpoints for every step of constructing and executing advanced DeFi goals: * `Retrieve supported tokens (tokenList).` * `Quote transactions (quoteIntent).` * `Solve for optimal transaction bundles (solveIntent), returning a ready-to-sign atomic EVM transaction.` * `Streamline approvals with Permit2 support, making authorisation safer and easier.` The widget sits at the UX layer, providing partners with plug-and-play capability to let users access intent-solves seamlessly inside their own products. **Why Integrate?**  ------------------- Integrating Haiku erases executional roadblocks for DeFi users and delivers: * Observable increase in conversion and volume as friction disappears. * Powerful portfolio outcomes, risk reductions, and market access never before possible in DeFi. * Future-proof products. The intent-based model is rapidly becoming the dominant UX paradigm within crypto.
