Frequently asked questions
What is Sei Network and what are its primary use cases?
Sei Network is a Cosmos-SDK Layer 1 mainnet optimized for high-performance trading and real-time apps, with SEI used for fees, staking, and governance. It powers orderbook DEXs, perpetuals, and latency-sensitive games/social apps that need sub-second finality and IBC connectivity for cross-chain liquidity. Typical gas costs are a fraction of a cent, block finality is ~0.5 seconds, and throughput has been benchmarked at 20k+ TPS, supporting heavy on-chain activity without congestion.
What makes Sei Network unique compared to other blockchain networks?
Sei is distinguished by Twin-Turbo consensus (optimistic block processing and intelligent block propagation) plus frequent batch auctions to mitigate MEV, delivering sub-second (~500–600 ms) finality and low-latency price discovery. Its parallelized execution and Sei v2’s parallelized EVM (with the SeiDB storage engine) push throughput to 20k+ TPS in benchmarks while keeping fees sub-cent—far faster and cheaper than typical L1s with multi-second finality and higher gas. Native IBC interoperability enables seamless cross-chain routing and settlement across Cosmos, sustaining high activity for DeFi and real-time apps.
What is the gas token used for Sei Network, and how to get it?
Sei Network uses SEI as the gas token for transaction fees. You can obtain SEI by bridging from other chains or purchasing using thirdweb Bridge.
