What Is Sei?

Sei is a layer-1 blockchain designed specifically for trading applications. Founded by Jeffrey Feng and Jayendra Jog, Sei launched its initial version in August 2023 and has since evolved into Sei v2, which introduced a parallelized EVM (Ethereum Virtual Machine) that can process multiple transactions simultaneously. Sei aims to provide the performance characteristics needed for institutional-grade decentralized exchanges and trading applications.

Sei's core innovation is its parallelized EVM, which allows the network to process multiple independent transactions concurrently rather than sequentially. When transactions don't touch the same state (for example, trades on different trading pairs), they can be executed in parallel, dramatically increasing throughput. This makes Sei one of the fastest EVM-compatible chains, with theoretical throughput of thousands of transactions per second and finality in under 400 milliseconds.

The blockchain includes several trading-specific optimizations built directly into the protocol layer. These include a native order matching engine that provides on-chain orderbook functionality, frequent batch auctions that protect against front-running and MEV (Maximal Extractable Value), and market-based parallelization that optimizes for the access patterns common in trading applications.

Sei v2 introduced backward compatibility with Ethereum smart contracts, allowing any EVM dApp to deploy on Sei without modifications while benefiting from Sei's performance advantages. This EVM compatibility also means standard Ethereum tools like MetaMask, Hardhat, and Remix work with Sei, lowering the barrier for developers.

SEI is the native token of the Sei network, used for transaction fees, staking with validators to secure the network, and governance. Validators and delegators earn staking rewards for participating in consensus. The low transaction fees on Sei make it practical for high-frequency trading applications where cost per trade is a critical factor.

The Sei ecosystem includes DeFi protocols focused on trading, such as DragonSwap (DEX), Yaka Finance, and various perpetuals platforms. The network has also attracted NFT marketplaces and gaming applications that benefit from its fast finality and low fees.

Getting Started With Sei

Getting started with Sei:

Step 1: Add the Sei network to MetaMask or use the Compass wallet.
Step 2: Acquire SEI from a cryptocurrency exchange.
Step 3: Transfer SEI to your wallet on the Sei network.
Step 4: Explore trading dApps, stake SEI with a validator, or participate in the DeFi ecosystem.

How to Get a Sei Wallet?

MetaMask

MetaMask works with Sei v2 since it is EVM-compatible. Add the Sei network through Chainlist and use it like any other EVM chain.

Compass Wallet

Compass is a wallet built specifically for the Sei ecosystem. It supports both Sei's native Cosmos-based addresses and EVM addresses, providing a unified experience for interacting with all Sei dApps.

Hardware Wallets

Ledger hardware wallets support Sei through MetaMask, providing secure offline key storage.

SEI is available on most major cryptocurrency exchanges:

Centralized Exchanges

SEI can be purchased on Binance, Coinbase, Kraken, OKX, and other major exchanges. Trading pairs include SEI/USDT and SEI/USD.

Decentralized Exchanges

On the Sei network, DragonSwap and other native DEXs allow you to swap tokens. SEI can also be found as a wrapped token on Ethereum DEXs.

Latest Sei News

Sei continues to develop its position as a high-performance trading chain with ongoing improvements to its parallelized EVM. Key developments include growing DeFi ecosystem activity, partnerships with trading and financial applications, and technical upgrades to push transaction throughput and finality even further.
