Sei is a Layer 1 blockchain built with the Cosmos SDK, initially optimized for high-speed decentralized trading with a built-in order book module and frontrunning protection. The network evolved with Sei v2 (2024) into a parallel EVM chain targeting 200,000+ TPS for any high-performance application. SEI is used for transaction fees, staking, and governance.
Sei uses Twin-Turbo Consensus — a combination of optimistic block processing and parallelized transaction execution. The chain supports both EVM (Solidity) and CosmWasm (Rust) smart contracts simultaneously, allowing developers to use either ecosystem. Sei's optimistic parallelization processes transactions concurrently and detects conflicts retroactively, achieving sub-400ms finality. The Giga upgrade (2025) targeted 200,000+ TPS. Sei has a native order book module at the base layer enabling decentralized exchanges to match orders without application-level complexity. Frontrunning protection is built into the ordering mechanism.
Trading applications on general-purpose blockchains like Ethereum suffer from high latency, MEV (frontrunning), and high gas costs. Sei was designed from the ground up to be the fastest L1 for digital asset exchange, with order book functionality at the protocol level, sub-second finality, and built-in frontrunning protection — making on-chain trading comparable to centralized exchange speed.
Native order book module at the base layer combined with Twin-Turbo parallel EVM consensus, enabling sub-400ms finality at 200,000+ TPS with built-in frontrunning protection — making it the fastest EVM-compatible blockchain.
Use multiple indicators together to build complex entry conditions for SEI.
Both are purpose-built DeFi L1s with Cosmos SDK; Injective focuses on a single on-chain order book with fee burns while Sei targets general high-throughput use cases
Both target high throughput via parallel execution; Sui uses object model with Move while Sei uses optimistic parallelization with EVM+CosmWasm
