Sei: The Layer 1 for Trading
Sei is built on a core thesis: blockchains' fundamental use case is exchanging digital assets. Scaling exchanges is pivotal for Web3's next growth phase. As an open-source, general-purpose Layer 1 blockchain, Sei is optimized at every stack level to provide the best infrastructure for trading digital assets.
Why Trading is Blockchain's Core Use Case
Beyond Traditional Trading
Trading in Web3 spans:
- Tokens & NFTs
- Real-world & metaverse assets
- Risk & social-likeness
Successful Web3 Apps Are Exchanges
Examples:
- Clear exchanges: Uniswap, OpenSea, Sushi.
- Indirect exchanges: Axie Infinity (NFT marketplace) and StepN (built-in DEX).
Even non-exchange apps derive value from asset trading:
- Bitcoin’s worth lies in its exchangeability.
- MetaMask users primarily swap assets via integrated DEXs.
- Aave borrowers seek liquidity for purchases.
The Future of Exchanges: Exponential Growth
Key Drivers
- Proliferation of digital assets with 24/7 price visibility.
- Regulatory pressures on CEXs pushing activity on-chain.
- DEXs must scale to handle rising adoption.
The Exchange Trilemma: Scalability Challenges
Exchanges face a tradeoff between:
- Decentralization
- Scalability
- Capital efficiency
