CoinDCX API setup
Follow these steps when connecting Lemma to your CoinDCX account.
Already connected? Act now — CoinDCX is deprecating unbound keys
CoinDCX made IP binding mandatory in October 2026 and is deprecating API keys that don't have one. There's no published grace period, so if your key still has Bind IP Address to API keyunchecked, don't wait for it to break mid-trade: delete it on CoinDCX and create a new one following the step below right away.
Most important
On the CoinDCX Create API Key page, check Bind IP Address to API key— CoinDCX now requires this on every key — and enter Lemma's execution server IP, not your own device:
Lemma and the execution engine call CoinDCX from this one cloud server, not your home or office IP. If you bind your own IP (or leave it unbound), CoinDCX will reject requests from Lemma and key tests will fail.
- Complete CoinDCX KYC and log in to your account.
- Open Create API Key. This isn't available inside the CoinDCX app— it's a page on CoinDCX's website. On a phone, tapping it opens your browser, and you'll need to log in there too (a browser login is separate from being logged into the app). If that's awkward on mobile, do this step on a computer instead. Enter a label (2–54 characters). Check Bind IP Address to API key and enter — this is now mandatory, not optional. Complete OTP and save the key and secret somewhere safe.
- In Lemma cockpit → Security & API (or the setup wizard), paste the key and secret, save, then run Test API Keys (Futures).
Need help? Open the setup guide from the cockpit banner or contact support with a screenshot of your CoinDCX API key settings (hide the secret).
A KYC-verified key is active immediately — there's no separate approval step.
