Why I'm excited about our (@BigBrainVC) investment in @HaikuTrade Blockchains were designed around a new atomic unit: the transaction. While this works well for updating software state, it is poorly suited for finance. In TradFi, assets connect seamlessly: a trader can declare a hedge or rebalance, and infrastructure handles the details. In DeFi, protocols must stitch together bespoke smart contracts just to achieve basic interoperability. TradFi’s atomic unit is outcome-based: “Fill this order at this price for this size under these constraints.” For DeFi to mature, its primitive must evolve from transaction-based to outcome-based. This is what Haiku is building - an engine that takes a desired outcome and compiles it into one on-chain call, executing all required intermediate steps within that single bundle of transactions. Currently, if you were to establish a delta-neutral USDT-ETH liquidity pool position on Uniswap Base while hedging exposure on Aave Polygon (starting with USDC) you would need to: 1. Lend USDC on Aave Polygon 2. Borrow ETH against their USDC collateral on Aave Polygon 3. Bridge ETH to Base via Stargate 4. Bridge the remaining USDC to Base via LiFi 5. Swap USDC for USDT on Aerodrome Base 6. Add USDT and ETH to the Uniswap Base liquidity pool This process involves six steps, five distinct protocols, and two separate networks. Managing this process manually can quickly become complex, time-consuming, and error-prone—especially if the user needs to rebalance their position over time. More importantly, this user isn’t particularly interested in engaging directly with Aave, Aerodrome, or other individual DeFi protocols. They just want a delta neutral position! What is Haiku? Haiku ingests a start-state and target portfolio as a structured intent, runs a proprietary convex optimizer to select and sequence primitives (swap/borrow/lend/repay/bridge) under protocol and risk constraints, then compiles the plan into a single bundle via a router that executes all legs in one call across chains—coordinating approvals, minimizing price impact, and guaranteeing all-or-nothing settlement with near-zero residuals. For swaps and bridging, Haiku uses third party solvers. Some examples of outcomes you can generate now: 1. Cross Chain Rebalancing: - Start with: USDC on Arbitrum. - Target: 50% ETH on Arbitrum + 50% wstETH on Arbitrum. 2. Zap into a vault with non-whitelisted assets - Start with: USDC on Arbitrum - Target: Deposit into a Morpho vault that only accepts eUSD as deposits 3. Delta-neutral LP position - Start with: USDC on Arbitrum. - Target: aArbUSDC (collateral) + cbETH (borrowed ETH exposure) Future Looking: There are a couple of really exciting use cases now and into the future: 1. Frontends/vaults can finally accept any asset: - Have you ever tried depositing into a vault, only to realize that you don’t have the right asset? The annoying friction of then having to find the most liquid DEX takes way too long. Now, frontends can integrate Haiku’s API and allow a user to do the swap without leaving their app. 2. New Primitives: - AI agents are currently limited in what they can do, often simply built on top of existing intent protocols. Allowing agents to define financial outcomes can let AI agent builders focus on their UX, rather than have to deal with transaction building. - Novel products that take advantage of one-click transaction building could lead to new DeFi derivatives or more complex, multi-step ones. 3. Institutions: - Trading firms can use Haiku to trade crypto on-chain in the same declarative way they trade TradFi/crypto assets off-chain. Oftentimes, yields are higher on-chain than off-chain, but execution risk limits on-chain trading.
