What Is Sei Network? Complete guide

We’re thrilled to share some exciting news — NOWNodes has just listed the Sei Network node!
This means developers and businesses can now connect directly to Sei RPC nodes in real time. No complicated setup, no infrastructure management — just fast, reliable access to the Sei network through our powerful RPC API.


What Is Sei Network, Exactly?

Sei is a Layer 1 blockchain designed with one specific goal — to make decentralized trading as fast and efficient as possible.

Unlike general-purpose blockchains, Sei Network focuses entirely on optimizing speed, scalability, and trading performance.
It offers sub-second finality, high throughput, and an architecture built to handle complex financial applications. Whether it’s a DEX, an NFT marketplace, or an on-chain trading bot — Sei provides the foundation to make it work faster and smoother.


What Is Sei Coin?

The native currency of the network is the SEI token — often referred to as Sei coin or Sei crypto.
All of these refer to the same thing: the digital token that powers the Sei blockchain.

The SEI token is used to:

  • Pay transaction (gas) fees
  • Stake and secure the network
  • Participate in on-chain governance

The Sei Ecosystem: Built for Speed and Innovation

Behind the Sei project stands Sei Labs, a team of innovators building the most efficient blockchain infrastructure for traders and developers alike.

The Sei ecosystem is already expanding rapidly — featuring decentralized exchanges, NFT projects, and powerful infrastructure providers like NOWNodes.
Thanks to our integration, you can now use Sei RPC endpoints to connect directly to the Sei mainnet.


Sei Network TPS and Performance

Speed matters — especially in crypto.
The Sei network TPS (transactions per second) rate is among the highest in the blockchain space, ensuring low latency and instant finality.

This high throughput allows developers to build real-time trading applications, automated market makers, and even gaming or social dApps that rely on lightning-fast execution.
When it comes to Sei protocol performance, every millisecond counts — and Sei delivers.
