Intent-Based Trading

A trading model where users sign a desired outcome (an intent) — e.g. “swap X for at least Y” — and solvers compete to fill it optimally. Also searched as intent trading or intent settlement. Protocols such as CoW Protocol use intents to reduce MEV versus sending a raw swap straight to the public mempool.

How Intent-Based Trading works in practice

Intent-based systems let a user state the outcome they want — this asset for that one, at no worse than this price — and have competing solvers work out the route. The user signs an intent rather than a transaction path.

Worked example

Instead of choosing a DEX and a route, you sign 'sell 10 ETH for at least 29,500 USDC'. Solvers compete to fill it, and the winner keeps any surplus above your limit or passes it back, depending on the design.

The mistake that costs people money

You are trusting a solver network to find a good price. Competition usually delivers, but a thin solver set can mean worse execution than routing yourself — and the surplus above your limit may not be yours.
