# Market Order

A Market Order is the fastest way to buy or sell any token, executing instantly at the best available onchain price — Definitive finds the most efficient swap path and completes the trade gaslessly across supported chains.

When a Market Order is submitted, Definitive automatically:

* Simulates the trade across connected DEXs to determine the most efficient route.
* Executes the transaction at the best possible price after accounting for slippage, price impact, and fees.
* Confirms settlement onchain, displaying the final execution price and fill details within seconds.
