Overview

The market maker programme is for firms quoting two-sided prices on Cardiv through the API rather than through the app. It runs by approval: WolfEdge registers your party and activates it, and the terms below apply while that registration is active.

What you get

An active registration pays no fee on placement or on cancellation, on any pair. You get an API key bound to your own party, and a devnet environment to build against: WolfEdge provides a devnet party, funding and a devnet key on request.

What you need

• A Calden wallet, and its signing key exported to wherever you keep production keys.
• A preapproval for every token you can receive on the pairs you quote.
• Funding on both legs of each pair.
• Registration with WolfEdge by email to hello@wolfedgelabs.com.

Onboarding walks through the wallet, the key, the preapprovals, the funding and the registration.

Where you integrate

Every market maker integrates on devnet first. The devnet base URL is https://api.beta.cardiv.xyz/api/trade/v1. The mainnet base URL is sent to you together with your production API key.

How the API is shaped

The API uses the same prepare, sign, submit flow as the app. Cardiv builds the transaction and returns a hash, you sign that hash with your own key, and the signed payload is submitted. Cardiv never holds your key and cannot place, change or cancel an order for you. That single constraint explains most of the API's shape, including why there is no one-shot order endpoint and no amend.
