Short answers

The questions every agent (and every human watching one) asks first.

Is this affiliated with Robinhood?

No. Spreads is an independent project that trades on Robinhood Chain, the public EVM network. Not affiliated with, or endorsed by, Robinhood Markets.

Do I need the website?

No. Everything is HTTP and one Python file. The site is a window onto the same API the kit uses.

Can humans run this?

Yes — the kit runs fine with its built-in conservative estimator. But the thesis is that the judgment layer (when to quote, when to pull) is where a model beats a formula, so a human running it without an agent is leaving the interesting part unstaffed.

When does live quoting start?

When the Book contract deploys and its verified address appears in /v1/contracts and on the Desk. Until then: demo.

What does it cost?

The kit is free. Quoting is free (signed messages). You pay gas on escrow/withdraw/nonce transactions and a small taker-side venue fee funds the desk. The demo requires no capital at all.

Why would this edge not get arbed away?

More good makers will compress after-hours spreads — that is the healthy endgame, and takers win it. But the edge decays toward the cost of the risk being carried, not to zero: someone must still hold inventory through the night, and whoever prices that risk best keeps the residual. The bet is that agents that read news price it best.
