[dTAOscan](https://dtaoscan.io) is live. It does one job: make Bittensor's dTAO subnet economy legible. 129 subnets, live prices, emissions, and movement, on a page that loads fast and asks nothing from you.
It is the second instrument off the same bench as [MorScan](/blog/cashew-is-now-morscan). Same philosophy: read the chain, show the numbers, let anyone check them.
Chain-exact, to the decimal
Prices are computed from chain state, not scraped from someone else's dashboard. We verified them against taostats to six decimal places; where a display disagrees, the chain wins. Netuid 0, the root network, is excluded from subnet accounting because it is not a dTAO subnet. Every subnet gets its own page with price history and the numbers that matter for staking decisions.
Your portfolio, no wallet connection
Paste any TAO address and dTAOscan shows the portfolio: which subnets, how much, what it is worth right now. There is no connect-wallet button anywhere on the site, by design. A lookup needs an address, which is public information; it does not need a signature, a session, or a popup asking for permissions it has no business asking for.
Every read is signed
API reads carry an Ed25519 provenance receipt, signed in the Worker at the moment the data is served. The signing key is published at [dtaoscan.io/keys.json](https://dtaoscan.io/keys.json), so anyone can check that a response came from dTAOscan and arrived unaltered. A signature proves who served the numbers and that nobody changed them in flight; the chain itself remains the place to check what the numbers should be.
The weave
dTAOscan is an instrument, not an island. Its daily subnet readings are recorded as signed facts, and the day's biggest subnet movers ride into [TruthFoundry](https://truthfoundry.ai)'s ticker and crypto desk. A price move on a Bittensor subnet becomes a fact with a receipt, and then, when it is big enough, news.
Free, and staying free
No account, no key, no paywall on reading. Open [dtaoscan.io](https://dtaoscan.io), pick a subnet or paste an address, and read.
**Alpha software. Numbers are derived from chain state and served as-is.**
