View ChartSei is a high-performance, open-source Layer 1 blockchain specifically designed to be the infrastructure for trading, offering unparalleled speed and reliability for decentralised exchanges (DEXs) and trading applications.
Trading-First Design: Sei is purpose-built from the ground up to optimise the trading experience, featuring innovations like Twin-Turbo Consensus and native order matching.
Blazing Speed: It is one of the fastest blockchains, achieving industry-leading transaction finality in under 400 milliseconds.
EVM & CosmWasm Compatibility: Sei supports both the Ethereum Virtual Machine (EVM) and CosmWasm, allowing developers from Ethereum and Cosmos ecosystems to deploy applications seamlessly.
Robust Ecosystem: A rapidly growing ecosystem of decentralised exchanges, NFT marketplaces, and DeFi applications is being built on Sei.
Native Token (SEI): The SEI token is used for transaction fees, staking to secure the network, and participating in governance.
Sei is a specialised Layer 1 blockchain that acts as a decentralised financial exchange, providing the foundational layer for trading-focused applications with its unique technical stack.

Sei was founded by Jayendra Jog and Dan Edlebeck. The project is developed and maintained by Sei Labs, a team with extensive experience in traditional finance and blockchain technology from companies like Goldman Sachs, Robinhood, and Databricks. The network is governed by a decentralised autonomous organisation (DAO), SeiDAO, which oversees protocol upgrades and ecosystem development. The public mainnet, Sei Pacific-1, launched in August 2023, marking its transition to a fully decentralised network.
Sei operates on a custom-built technology stack optimised for trading. Its core innovation is the Twin-Turbo Consensus, which enhances the popular Tendermint consensus engine. This system introduces two key optimisations: Intelligent Block Propagation and Parallelisation. The former reduces communication overhead between validators, while the latter allows for the simultaneous processing of independent transactions, drastically increasing throughput.
Furthermore, Sei features native order matching at the chain level. Unlike typical DEXs where matching logic is handled by smart contracts, Sei bakes this functionality directly into the blockchain. This allows for features like frequent batch auctions, which aggregate orders within a block to provide fairer pricing and protect users from front-running and maximal extractable value (MEV). Its compatibility with both the EVM and CosmWasm smart contract environments makes it highly accessible for developers.
Sei's primary value proposition is its singular focus on being the best infrastructure for trading. While other general-purpose blockchains can host DEXs, Sei is architected specifically for this use case, resulting in superior performance. Its sub-400ms block finality is among the fastest in the industry, providing a user experience comparable to centralised exchanges.
The native order matching engine is a fundamental differentiator. By handling order books at the consensus layer, Sei enables more sophisticated trading mechanisms (like limit orders) and enhanced security against common DeFi exploits. Its parallel execution and optimistic processing allow it to scale efficiently under the high load typical of financial markets. This specialisation attracts trading-focused applications, creating a powerful network effect where liquidity and users congregate on the fastest and most reliable platform.
The SEI token is the lifeblood of the Sei Network, with several critical utilities:
Network Fees: SEI is used to pay for transaction and smart contract execution fees (gas) on the network.
Staking: Users can stake their SEI tokens with network validators to help secure the blockchain. In return, they earn staking rewards from block emissions.
Governance: SEI token holders can participate in the on-chain governance of SeiDAO, voting on proposals that shape the future of the protocol, such as parameter changes and treasury management.
Native Asset: As the base currency of the Sei ecosystem, SEI is a primary trading pair for assets on Sei-based DEXs and is used across various DeFi applications for lending, borrowing, and liquidity provision.
The Sei ecosystem is expanding rapidly, capitalising on its high-speed infrastructure. The launch of the EVM compatibility has been a major catalyst, enabling a flood of Ethereum-native projects to deploy on Sei with minimal code changes. The ecosystem now hosts:
Leading DEXs: Major decentralised exchanges like Astroport and Diffusion have established presence, offering deep liquidity.
NFT & Gaming: NFT marketplaces and gaming platforms are building on Sei to leverage its fast transaction speeds for minting and trading.
DeFi Primitives: A full suite of DeFi applications, including lending protocols, yield aggregators, and perpetual futures exchanges, is being developed.
Developer Growth: Significant funding from the Sei Foundation and ecosystem grants is attracting developers to build the next generation of trading applications.
Sei does not use a traditional proof-of-work mining model. Instead, new SEI tokens are created through a proof-of-stake (PoS) consensus mechanism. The only way to "mine" or earn new SEI is by participating in network security through staking. Users can delegate their SEI tokens to a validator node. These validators propose and validate new blocks. As rewards for this service, the network mints new SEI tokens, which are distributed to validators and their delegators (stakers) proportionally. This process is often referred to as "staking," not mining.
Securing your SEI tokens is paramount. For active trading, a reputable exchange like BTCC offers robust security measures. For long-term holding, use a self-custody wallet.
Hardware Wallets: The safest option. Devices like Ledger or Trezor store your private keys offline, making them immune to online hacks.
Software Wallets: Reputable mobile or browser extension wallets (e.g., Keplr, MetaMask configured for Sei) offer convenience for interacting with dApps. Always download from official sources.
Best Practices: Never share your private key or seed phrase. Use strong, unique passwords and enable all available security features (2FA). Double-check website URLs to avoid phishing scams.
SEI is a popular cryptocurrency listed on many exchanges. For a secure and liquid trading experience, we recommend using a major platform like BTCC.

TradeA comparison of core architecture and positioning among three next-generation high-throughput Layer 1 networks — Sei (SEI), Sui (SUI), and Aptos (APT):
| Dimension | Sei (SEI) | Sui (SUI) | Aptos (APT) |
|---|---|---|---|
| Architecture & Language | Parallel EVM, native Solidity, and EVM ecosystem tool support. | Parallel execution, custom Sui Move language. | Parallel execution (Block-STM), standard Move language. |
| Development Barrier | Frictionless migration of Ethereum dApps, broad compatibility. | Requires learning Move, higher barrier to entry. | Requires learning Move, higher barrier to entry. |
| Niche & Focus | Focus on high-frequency DEXs, DeFi, and on-chain order books. | Focus on general Web3, gaming, and object-oriented apps. | Focus on high-performance Web3 apps and enterprise integration. |
Summary: Sei holds a major advantage with its parallel EVM and seamless compatibility with Ethereum tools, whereas Sui and Aptos offer next-generation secure memory models and general scalability via the Move language.
