Sei is a Layer 1 blockchain launched in 2023. It is designed for fast and cheap financial transactions. The network aims to combine the network effects of Ethereum with the performance of Solana.

What Sei is used for

Sei is a sector-specific Layer 1 blockchain. It is built to optimize trading processes for decentralized exchanges (DEXes). The platform supports asset trading and can be used for NFT and in-game item exchanges.

The network is currently scaling through the Giga roadmap. This plan targets 200,000 TPS and sub-400ms finality. A key part of this is the Eidos upgrade, which replaces Merkle tree storage with FlatKV and lattice hashing. Phase one of Eidos is live in the v6.6 mainnet release.

Sei has also worked with Mastercard on a joint report regarding institutional blockchain adoption. This research suggests that technology is no longer the primary barrier for banks and asset managers moving into production.

Wallet, network, and custody checks

Users must verify the network they are using before transferring funds. SEI exists across different platforms with different addresses:

• Sei Network: usei
• Sei v2: 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
• Osmosis: ibc/71F11BC0AF8E526B80E44172EBA9D3F0A8E03950BB882325435691EBC9450B1D

You can use the Sei explorer to check addresses and transactions. For deeper verification, the official website, whitepaper, and source code are available.

Common mistakes before buying SEI

Avoid these frequent errors when acquiring SEI:

• Using a lookalike contract address or the wrong network. Always verify the address through official sources.
• Assuming all exchanges support the same network for deposits and withdrawals.
• Ignoring country-specific availability or KYC requirements before opening an account.
• Relying on live price or volume snapshots as permanent data.

Route, liquidity, and availability caveats

Deposit and withdrawal support is not verified for the routes listed above unless the exchange explicitly states it during the transaction.

Availability varies by region. For example, Bybit and MEXC have specific lists of banned countries, including the US, Canada, and the UK. KYC requirements are mandatory for some platforms, such as Bybit and MEXC.

Sources and methodology

The exchange routes in this guide come only from verified market-pair rows in our database. We use web research and news for background and risk context. Information from CoinMarketCap pages is treated as low-confidence context and is not used as proof of fees, liquidity, or contract safety. Live market values are omitted because they change too frequently to remain accurate in a static guide.
