What changed
Week to 3 NovemberNothing we measure moved much this week: exchange depth on Coinbase, exchange depth on Kraken, trading volume, reported supply and price are all within their usual range.

What it actually costs to sell SEI
Selling $100,000 of SEI into each exchange’s resting bids, measured against the mid price:
| Exchange | Lost | Got back | Measured |
|---|---|---|---|
| Coinbase SEI/USD | 0.21% | $99,790 | 2026-11-03 |
| Kraken SEI/USD | 0.45% | $99,549 | 2026-11-03 |
Exchange figures need an account there (and KYC, a permitted country, the tokens already deposited), are before trading fees, and are never averaged with the on-chain figure. Binance is not included: it refuses requests from the region our servers are in. How this is measured →
Watch this number instead of remembering it. A free account keeps SEI on a list, records where it stood the day you added it, and emails you if selling it on these exchanges gets materially harder — one message, not a series. The measurement itself stays public; the account is for being told when it moves without you looking.
What Sei is
Sei is a Layer 1 blockchain built to scale the Ethereum Virtual Machine through parallelized execution, with the stated aims of faster transactions, lower fees, and straightforward smart contract deployment. The source material does not name a founding team or a launch date.
Sei's approach centers on running EVM operations in parallel rather than sequentially, which is intended to remove throughput limits typical of earlier EVM-compatible chains while preserving compatibility with existing Ethereum tooling and contracts. A planned upgrade called Giga is described as targeting a 50x increase in EVM throughput, through changes to execution, consensus, and storage layers, with the goal of reaching performance comparable to centralized web infrastructure.
The 50x throughput figure describes a future upgrade, not a measured or delivered result — nothing in the source confirms Giga has shipped or that the claimed gains have been independently verified. "Full Ethereum compatibility" is likewise a design goal as stated, not a tested guarantee of identical contract behavior. CoinGecko classifies Sei under several categories — Smart Contract Platform, DeFi, Layer 1, Parallelized EVM — and lists it within the Coinbase Ventures, Multicoin Capital, Delphi Ventures, and GMCI Layer 1 Index portfolios; inclusion in a venture portfolio or index is a classification, not a performance endorsement or a signal of security. No information here speaks to validator count, decentralization, audit history, or uptime, and none of it should be inferred.

Our own measurement · measured 3 November 2026
SEI can be staked by delegating it to a validator, which keeps a percentage as commission. Taking it back out takes 21 days, during which it earns nothing and cannot be moved.

About the asset
Sei has no token contract — it is the native asset of its own chain, not a token issued on someone else's.
