What is Sei (SEI)?
Sei is a specialized Layer 1 blockchain built to optimize decentralized trading and the exchange of digital assets. It is designed to be one of the fastest blockchains in the industry, focusing on providing a high-performance infrastructure for decentralized applications such as exchanges, NFT marketplaces, and gaming platforms. The project was founded by industry veterans with experience from Goldman Sachs and Robinhood. It utilizes a custom consensus mechanism known as Twin Turbo Consensus, which allows for extremely fast transaction finality, often measured in milliseconds. This is significantly faster than many traditional blockchains and aims to provide a user experience similar to centralized applications. A key innovation of the network is its parallelized Ethereum Virtual Machine. This technology allows the blockchain to process multiple transactions at the same time rather than one by one, which increases the overall capacity and speed of the network. This feature also makes it compatible with existing Ethereum-based tools and smart contracts, allowing developers to easily move their projects to the Sei network without rewriting their code. The network also includes a native order matching engine built directly into the blockchain layer. This helps decentralized exchanges operate more efficiently by handling order placements and executions on-chain with low latency. This design choice specifically addresses common issues in blockchain trading like network congestion and high fees. The native token, SEI, serves several roles within the ecosystem. It is used to pay for network fees, secure the blockchain through staking, and allow holders to participate in governance decisions. Additionally, the token can be used as collateral in various decentralized finance applications built on the platform. The ecosystem is growing to include a wide range of services beyond just trading, such as social platforms and real-time gaming. By combining high speed with Ethereum compatibility, the project aims to serve as a foundational layer for the next generation of digital asset exchange. Through its unique architecture, the network attempts to solve the scalability challenges that have historically limited the growth of decentralized trading environments. Learn more

MoreSei (SEI) FAQ
Sei is a sector-specific Layer-1 blockchain optimized specifically for high-performance trading across various sectors, including decentralized finance, gaming, and NFTs. Unlike general-purpose blockchains that handle all types of applications with the same priority, Sei is engineered to provide the speed and performance of high-scale systems while maintaining decentralized security. It focuses on solving the scalability issues inherent in traditional networks to support mass-market applications.
Sei v2 introduces the industry's first Parallelized Ethereum Virtual Machine (EVM). While traditional blockchains process transactions sequentially, Sei’s "Optimistic Parallelization" allows the network to process multiple transactions simultaneously. If transactions do not conflict, they are completed at the same time, significantly increasing throughput. This upgrade allows developers to deploy existing EVM-compatible smart contracts on Sei without changing their code, benefiting from dramatically faster execution speeds.
Sei is designed for industry-leading speed, achieving a transaction finality of approximately 380ms. The network is capable of handling between 12,500 and 28,000+ transactions per second (TPS). Looking forward, the planned "Giga" upgrade aims to push these limits even further, targeting over 200,000 TPS. This level of performance is intended to support massive, Web2-scale applications that require near-instant execution and high-frequency interaction.
The SEI token serves several critical roles: it is used to pay for network gas fees, enables decentralized proof-of-stake (DPoS) through staking to secure the network, and facilitates governance by allowing holders to vote on protocol proposals. Additionally, it serves as native collateral for applications built on the chain. The total supply is capped at 10 billion tokens, with a structured vesting schedule designed to support long-term ecosystem growth and development through 2030.
Because Sei v2 supports both EVM-compatible (0x) and native (sei1) addresses, users have several options. Popular choices include specialized ecosystem wallets and widely used EVM-compatible wallets. To move assets from other networks to Sei, users can utilize the official Sei Bridge or various integrated industry-standard bridging protocols. These tools allow for the seamless transfer of liquidity between different blockchain environments, ensuring accessibility for users across the crypto space.
Sei provides a "Built-in Order Matching Engine" at the protocol level. Unlike other blockchains where developers must build their own order book infrastructure from scratch, Sei allows them to plug directly into a high-speed engine maintained by the chain itself. This, combined with full EVM compatibility, allows developers to port their existing smart contracts with zero modifications. Developers gain the benefit of parallel execution and high throughput without the complexity of re-engineering their core application logic.
Convert Sei (SEI) into other assets
After purchasing Sei (SEI), you can trade it for fiat currencies or other cryptocurrencies. LBank offers over 200 Sei (SEI) trading pairs, making it easy to enter and exit the market.
