Opfico 101

Opfico is a liquidity protocol for emerging prediction venues. A venue lists qualifying books once. Makers quote them from one desk. Fills print on the venue matching engine.

Two surfaces

Makerbook is the maker desk: the board, terms, terminal, risk controls, rebates, and venue credits. Factory is the venue desk: registry, Handshake, reward programs, rebates, and credits.

How a book pays

1. The venue proves its domain and publishes a Directory of designated markets.
2. Handshake connects Authport (who may quote) and Router (where fills go).
3. Factory sets min shares, max spread, rebate cut, epoch, and the credit ticker.
4. Makers rest size in band on Makerbook. Rewards, rebates, and credits accrue there.
5. Router drop-copies fills to the venue engine. The venue keeps matching.
