04 · exact additive research priority
What does the evidence say about Sei?
Sei scores 39.1 out of 100 inside DeFi, ranked 23 of 29 rated coins on 76% evidence. The four displayed point contributions add exactly to the total; missing evidence pulls only the affected factor toward neutral and lowers its stated coverage. It ranks research attention within one theme, never portfolio action, and it is not comparable across themes.

No valuation section exists on this page, for any coin. There is no company-style P/E or PEG for a token, and historical market capitalisation is not held at all, only a dated current snapshot, so no ten-year valuation band can be built honestly. Where a protocol publishes fees or revenue, the yield against that dated snapshot is shown above instead.

Does Sei have a P/E ratio?
No. There is no company-style P/E or PEG for a crypto token, and no valuation band is shown on this page because the data to build one honestly does not exist: historical market capitalisation is not held, only a current snapshot. Where a protocol publishes fees or revenue, this page shows the yield against that dated snapshot instead.

In the 30 days to 30 October 2026, DefiLlama shows $2.2K of fees and $2.2K of protocol revenue for Sei. Over 90 days: $5K of fees and $5K of revenue. Fees are what users paid; revenue is the part the protocol keeps.
Does Sei generate network fees?
Sei's trailing twelve-month network fees is $84.7K, down 54.4% on the year-earlier period. Network activity is not token-holder earnings: whether it accrues to the token depends on the protocol's own burn, buyback and distribution rules.
