Sei labels itself the very first Layer 1 blockchain built for a specific sector. Sei intends to streamline digital asset transfers, especially when performed via a decentralised exchange (DEX). Built atop the Cosmos infrastructure providing superior scalability to many of its competitors. In short, Sei intends to combine the ease of use you find on a centralised exchange like Swyftx, with the security and anonymity of a DEX.
SEI is the native token of the Sei protocol and can be used to pay for network fees, or participate in staking, governance and more.
