Intent-Based DEXs Are Changing How Decentralized Trading Works

The architecture of decentralized exchanges has undergone a structural transformation since the introduction of the Automated Market Maker model. Uniswap v2 and v3 established a standard for programmable liquidity that enabled the growth of on-chain trading volume from marginal figures to trillions of dollars.

However, the AMM model imposes structural costs that manifest as slippage on large orders, impermanent loss for liquidity providers, and vulnerability to MEV extraction. The x*y=k price curve determines that the effective price of a trade depends on the order size relative to the pool size, disproportionately penalizing traders executing significant volumes.

Intent-based systems have emerged as a response to these limitations. In contrast to the imperative approach of AMMs, where the user specifies the complete execution path —including the liquidity pool, slippage tolerance, and gas payment— the intent model adopts a declarative approach: the user signs an off-chain message specifying a desired outcome, without detailing the execution method.
