Basics
Who is this for
Venues run programs. Makers quote them.
Venues
An operator registers the venue, holds the Venue License, and publishes the program from Factory. Listing a market is a decision in Factory. The venue's own engine still matches the order.
Market makers
A maker is a Solana pubkey. On Makerbook they see one board of qualifying markets, quote from the terminal, and follow rewards, rebates, and credits for each venue.
Where to go next
Factory and Makerbook each have their own guide. The protocol pages here stay on what Opfico is, before either app.
