Intent-Based Protocols Disrupt DeFi Trade Execution

DeFi users often believe they directly interact with automated market makers (AMMs) when swapping tokens on platforms like Uniswap or SushiSwap. However, a newer model has emerged that restructures this flow: intent-based protocols.

In these systems, the user signs an 'intent,' a declarative statement of their desired result, rather than broadcasting a specific transaction. A network of solvers then competes to fill this intent at the best possible price, off-chain, without exposing the order to the public mempool.

Traditional AMM interaction has several problems. It's vulnerable to MEV (Maximal Extractable Value) bots that monitor pending transactions and execute sandwich attacks, where they buy before your trade pushes the price up, then sell after, extracting value from the spread. These attacks have been estimated to cost retail users $200 million to $300 million annually on Ethereum alone.

Intent-based protocols like CoW Protocol and UniswapX address these issues by allowing solvers to compete in a batch auction format. This creates opportunities for direct matching, reducing fees and spreads. Solvers operate at their own risk, fronting capital and handling execution complexity, but competition between them compresses the margin, pushing more value back to users.

CoW Protocol, launched in 2023, has processed over $80 billion in cumulative volume, making it one of the largest DEX protocols by trade count. UniswapX, launched in 2023 as well, adds an intent-based execution layer on top of Uniswap's existing liquidity pools.
