What is Sei?
Sei is a Layer 1 blockchain purpose-built for trading. While most blockchains are general-purpose (they can do anything, but aren't optimized for anything in particular), Sei was designed with one specific use case in mind: financial exchanges.
This means several things are built into Sei's core that other chains handle through add-on smart contracts: a native order book module (so DEXs can run proper limit orders without AMM limitations), parallelized execution (independent transactions process simultaneously), and frequency batch processing (orders submitted within the same block are all matched at once, reducing front-running).
💡 Why does "built for trading" matter? Consider what happens when you trade on Uniswap (Ethereum DEX): an AMM pool sets the price, you pay gas during high congestion, and bots often front-run your trade. On Sei: an order book matches buyers and sellers directly, parallel execution keeps fees low regardless of congestion, and batch processing reduces MEV (front-running). The trading experience is fundamentally better.

Why Build a Blockchain Specifically for Trading?
Sei is a Layer 1 blockchain built specifically for trading — not "also supports trading" like most chains, but architecturally designed from the first line of code for fast, low-cost order-book matching. While Ethereum, Solana, and Cosmos chains can run DEXs, none of them were optimized specifically for financial trading. Sei took the battle-tested Cosmos SDK and rebuilt critical execution components to handle the demands of high-frequency, high-volume order matching at decentralized exchange scale.
The original Sei differentiation was speed: sub-400ms finality for trading applications, with built-in native order matching that sidesteps Cosmos's normal slow execution path. Sei v2 (2024) expanded this dramatically by becoming the first mainnet blockchain with both native EVM compatibility and optimistic parallelization. This means any Ethereum dApp deploys on Sei without code changes, but immediately gains parallel transaction execution — dramatically higher throughput than standard sequential EVM processing.
Sei's investor base reflects its trading-focused thesis: Multicoin Capital (trading-focused crypto fund), Coinbase Ventures, and notably Hudson River Trading — one of the largest quantitative trading firms in traditional finance, with $50B+ daily volume. When TradFi HFT shops back a blockchain for trading, it signals genuine infrastructure potential. The SEI token pays gas fees, stakes to secure the network, and governs the protocol's development toward its goal of becoming crypto's fastest trading-optimized chain.
Sei at a Glance
How Does Sei Work?
Sei's technical architecture has several innovations layered on top of Cosmos SDK. Here's what sets it apart from generic blockchains:
Parallel transaction processing
Most blockchains execute transactions sequentially — one after another. If transaction A and transaction B don't touch the same accounts, they can safely run simultaneously. Sei identifies non-conflicting transactions and processes them in parallel, multiplying throughput without increasing block size.
Native order book matching engine
Instead of every DEX building its own AMM, Sei provides a shared order book module at the protocol layer. DEXs simply interface with it. Within each block, all submitted orders are collected and matched simultaneously — eliminating the front-running that plagues AMMs where bots sandwich your transactions.
Twin-turbo consensus
Sei's consensus mechanism starts processing the next block before the previous one finalizes ("optimistic block processing") and only transmits changed state between validators rather than full blocks ("intelligent block propagation"). Combined, these achieve finality in under 400ms — faster than a heartbeat.
Sei v2 — EVM + CosmWasm simultaneously
Sei v2 can run both Ethereum Solidity contracts (EVM) and native CosmWasm contracts on the same chain. A developer can build with MetaMask, Hardhat, and standard Ethereum tools while benefiting from Sei's trading optimizations automatically. This dual-VM approach is one of very few implementations at scale.
What is SEI Used For?
SEI token underpins the entire network's security, operations, and governance:
⛽ Gas Fees
Every transaction on Sei — swaps, smart contract calls, NFT mints — requires a small SEI fee. As usage grows, fee demand grows proportionally. Unlike some chains, Sei's fees are designed to stay low (a feature for trading platforms where users make thousands of transactions).
🔒 Network Security (Staking)
Sei uses Delegated Proof of Stake. Validators bond SEI to participate in consensus; delegators stake SEI to validators and earn rewards (~15–20% APY has been common). Staked SEI cannot be traded, reducing circulating supply. Slashing conditions penalize dishonest validators.
🗳️ Protocol Governance
SEI stakers vote on protocol upgrades, parameter changes, and ecosystem fund distribution. Major decisions — like the v2 EVM upgrade — required community governance votes. The more SEI you stake, the more voting weight you carry.
📈 DeFi Collateral and Liquidity
As the Sei DeFi ecosystem grows, SEI is used as collateral in lending protocols, provided as liquidity in trading pools, and farmed for rewards. With $500M+ TVL on Sei, the range of DeFi use cases expands continuously.

The History of Sei
Jay Jog and Jeff Feng came from traditional finance — Robinhood and Goldman Sachs respectively. They'd seen firsthand how modern financial systems work and how far DeFi was from matching them. In 2022, they founded Sei Labs with a simple but ambitious thesis: rebuild the financial exchange from scratch as a blockchain.
The Cosmos SDK gave them a foundation — a proven blockchain toolkit used by Cosmos, Injective, and dozens of other chains. But they added layers that Cosmos didn't have: the order book module, parallel execution engine, and twin-turbo consensus.
The $30M Series A at an $800M pre-launch valuation in early 2023 was a statement of confidence from blue-chip crypto investors. Multicoin Capital, Jump Crypto, and Coinbase Ventures all believed in the trading-chain thesis. When mainnet launched in August 2023, an airdrop distributed SEI to early testnet participants — generating significant community engagement.
Key Events Timeline
Jay Jog and Jeff Feng co-found Sei Labs, spinning out of Robinhood and Goldman Sachs. The thesis: build a blockchain for trading from scratch, not bolt trading onto an existing chain.
Sei raises $5M in seed funding led by Multicoin Capital, with participation from Coinbase Ventures. The team moves to build an entirely new Cosmos-based chain.
Sei raises $30M Series A at a $800M valuation — one of the largest raises for a pre-launch Layer 1. Framework Ventures, Jump Crypto, and Distributed Global participate.

SEI Tokenomics and Staking
SEI has a total supply of 10,000,000,000 tokens, with a majority allocated to community and ecosystem. Staking yields are among the highest in the Cosmos ecosystem — and Sei v2's fee burns add a deflationary offset.
| Allocation | Share | Vesting / Notes |
|---|---|---|
| Ecosystem & Community | 51% | Developer grants, incentives, airdrops |
| Team & Employees | 20% | 12-month cliff, 48-month linear vest |
| Foundation | 20% | Protocol development and partnerships |
| Seed & Private Investors | 9% | Multicoin, Coinbase Ventures, Jump |
Inflation + fee burns: Sei currently has ~6% annual inflation paid to validators and stakers — typical for Cosmos chains. Sei v2 introduced a fee burn mechanism (similar to Ethereum's EIP-1559) where a portion of transaction fees is permanently destroyed. As Sei's usage scales, these burns increasingly offset inflation — at sufficient adoption, SEI could become deflationary.
Sei Ecosystem: DApps and Protocols
Sei's ecosystem grew rapidly after v2 EVM compatibility opened the network to Solidity developers. Here are the key protocols defining what Sei DeFi looks like today:
The flagship DEX on Sei, combining standard AMM liquidity with concentrated liquidity positions (Uniswap v3-style). As Sei's default exchange, DragonSwap is the central liquidity hub for most trading pairs and token launches on the network.
A decentralized perpetuals protocol that was among the first major dApps on Sei. Levana leverages Sei's native order book and sub-400ms finality to offer tight execution on perpetuals — one of the core use cases the chain was purpose-built to enable.
Lending and borrowing protocol that migrated to Sei after the v2 EVM launch. Silo's isolated lending model limits contagion risk — if one collateral asset gets exploited, other lending pools remain protected. Institutional-grade risk management built for a high-speed chain.
A ve(3,3) model DEX — inspired by Velodrome — that adds vote-escrowed token mechanics to Sei. Liquidity providers and governance token holders vote on emissions distribution, creating more sophisticated incentives than simple AMMs and attracting long-term protocol participants.
Risks and Considerations
Very competitive L1 market
Sei competes against Solana, Aptos, Sui, and Injective — all Layer 1 blockchains with strong DeFi narratives. Sei's trading-specific focus is a differentiator but also limits its addressable developer market compared to general-purpose chains.
Ecosystem maturity
Despite technical excellence, Sei's application ecosystem is still early-stage. The number of active dApps, TVL, and user base lags significantly behind established chains. Ecosystem growth takes years of developer incentives and user acquisition.
EVM migration growing pains
Sei v2's EVM compatibility is a double-edged sword — it expands the developer audience but requires maintaining two execution environments simultaneously. Bugs or incompatibilities at the EVM/Cosmos interface could cause unexpected issues.
SEI inflation
Like most Cosmos-based chains, Sei has staking emissions that dilute non-stakers. Delegating SEI to a validator to earn staking rewards is generally necessary to avoid being diluted by inflation over time.
Where to Buy SEI
SEI is available on all major exchanges. It's also the native token you'll need if you want to interact with dApps on the Sei network. See our how to buy crypto guide for a step-by-step walkthrough.
