Callouts

Honest by design. Real USDC on Base mainnet. No token. N=0 external buyers — every number is real or an honest zero.
Every surface imports the ONE theme module — services/_content/university/theme.mjs — for all styling and layout. No hand-rolled palettes, no per-page CSS forks; the shared stylesheet is also served at /assets/mercury.css. If you need more than 3 colors, you don’t have any colors.

The CTA — liquid glass

Verifiable Web Fetch

Live
The headline service: fetch + EIP-191 signed receipt.
Open

Topbar & footer

The shell wrapping this board IS the live component — page() renders the same topbar (planet 26 + 900-weight wordmark + nav) and the same machine-discovery footer on every surface, so a break there is a break everywhere.

Surfaces

the real mounted index — real paths only
01
University
/university — the agent-payable storefront: every live service, honest prices from the one registry.
02
Docs
/university/docs — buyer quickstart: discover, pay over HTTP 402, verify the receipt offline forever.
03
Developers
/university/developers — rails & access: x402 today; API-key rail when it ships.
04
Treasury
/university/treasury — one ledger, honest zeros, every wallet auditable on BaseScan.
05
Style
/university/style — this board: the 3-color system and every shared component, live.
06
Trust
/trust — operator entity + the three verify-yourself claims (receipt · BaseScan · catalog).
Mercury — black, white, red, and never a fake number. Real USDC on Base mainnet, no token, the in-game currency stays testnet.
