What is a DEX on Sei Network?
A decentralized exchange (DEX) lets you trade tokens on Sei Network directly from your wallet, with no account, no custody, and no middleman. Sei Network's DEX liquidity includes Uniswap and other onchain venues. Prices and depth differ from one venue to the next, so the best price isn't always in the same place. Oku aggregates Sei Network's DEX liquidity into a single interface: you enter a trade once, and Oku routes it for the best execution. You get the best price on Sei Network without checking venues yourself, and Oku charges 0% fees on top.

What is Sei Network?
Sei is a Layer 1 blockchain originally built on the Cosmos SDK and focused on high-performance trading. Sei V2 introduced EVM compatibility, allowing Solidity developers to deploy directly alongside the chain's existing CosmWasm environment — making it one of the few chains that supports both execution environments natively. The consensus layer uses an optimized version of Tendermint targeting sub-second finality, with built-in features like parallelized execution and native order matching designed for trading applications. SEI is the native gas and staking token. The ecosystem has focused heavily on DEXs, perpetuals, and trading-oriented infrastructure. For users bridging to Sei, the EVM side is the most relevant entry point for standard DeFi activity.
