Connect Coinbase to your portfolio
Your Coinbase holdings land in your Celsmar portfolio and update every night. Celsmar only reads them: it never sends orders or moves money.
What you need
To connect Coinbase we ask for these API details. You paste them into your portfolio and we store them encrypted:
- Key name or id
- Private key
Where to create it at Coinbase
At portal.cdp.coinbase.com: API Keys → Create API key, with the «View» permission only (no Trade or Transfer). Copy the key name (or id) and the full private key.

What Celsmar reads from Coinbase
The balance of each cryptocurrency. Cash in euros or dollars does not go into the portfolio. If the broker does not give the average price of a holding, we ask you for it before importing instead of making it up.
Security
The key is stored encrypted with AES-256 on servers in the European Union and never goes back to your browser. Disconnect whenever you like and it is deleted. Where Coinbase lets us see the permissions, we check that the key cannot trade or withdraw and, if it can, we reject it.
Frequently asked questions
Can Celsmar trade in my Coinbase account?
No. Celsmar only reads your holdings with a read-only key and never sends orders or moves money. If Coinbase shows the key's permissions and it can trade or withdraw, we reject it.
How often does my Coinbase portfolio update?
Every night, automatically, and whenever you press Sync in the portfolio (at most once a minute). Whatever you buy or sell at the broker is recorded on its own.
How much does connecting Coinbase cost?
Connecting brokers is part of the Pro plan, with up to five brokers at a time; on Enterprise, as many as you like. On Free you can see the brokers and how they connect.
What if I would rather not create a key at Coinbase?
You can import a Coinbase statement as CSV or Excel, or a screenshot of your holdings, and review them before they go into the portfolio.
