How to create a read-only MEXC API key

Open MEXC API Management ↗

We checked these steps against MEXC's own documentation on 25 September 2026. MEXC can rename a button at any time. If a label differs, look for the same permission.

Before you start

• MEXC may require a phone number, email and Google Authenticator linked to your account before you can create a key.
• Netherlands residents: MEXC is winding down Dutch accounts. Its own announcement gives a final batch deadline of 23 October 2026, with restrictions from 24 October and offboarding complete on 31 October. From 00:00 UTC on 24 October MEXC itself closes any open futures position at a fair price, so those positions disappear from a Dutch account on a sync that otherwise succeeds — that is the wind-down, not a fault here, and reconnecting cannot bring them back. A Dutch account will stop returning balances — connect it only if MEXC still serves you.

Permissions

Turn on only:

• View Account Details (spot)
• View Account Details (futures, only if you hold futures)
• View Order Details (futures, only if you hold futures)

Keep these off:

• Order Placing (spot and futures)
• Any withdrawal permission, including View Deposit/Withdrawal Details
• Read transfer information and any other transfer permission
• Edit Account Info
• Margin and P2P permissions

Steps

Sovereign connects to MEXC from one fixed IP address. The connection form in Sovereign shows it next to these steps, with a copy button.

1. Press “Open MEXC API Management” above and sign in to MEXC.
2. In the spot permissions, tick “View Account Details”. Leave “Order Placing” and every withdrawal, transfer, margin and P2P box unticked.
3. If you hold futures, also tick “View Account Details” and “View Order Details” in the futures permissions.
4. In “Notes (Required)”, type Sovereign.
5. In “Link IP Address (optional)”, paste Sovereign's IP address, and nothing else.
6. Tick “I have read and agree to the Risk Reminders for API Users”.
7. Click “Create” and complete MEXC's security verification.
8. Copy the access key and the secret key now. MEXC shows the secret key only once.
9. In “My API Key”, check your new key's “Remaining Validity (Days)”.
10. Paste the access key into API KEY and the secret key into API SECRET in Sovereign, then press “Connect & Sync”.

Where each value goes in Sovereign:

• Access key → API KEY
• Secret key → API SECRET

Does a MEXC API key expire?

• With an IP restriction: Not confirmed by MEXC — check “Remaining Validity (Days)” in “My API Key”.
• Without an IP restriction: Switched off after 90 days (you can renew it from 5 days before).

MEXC publishes no clear expiry rule. If the key stops working, Sovereign marks the connection as expired and asks for a new key.

Spot balances, your futures account equity and open futures positions sync. MEXC has no funding wallet and no API for Earn or the fiat/P2P balance, so those never appear. In the futures permissions, “View Account Details” reads your futures account equity and “View Order Details” your open positions; without them the spot balances still come through, so tick them only if you hold futures. Each sub-account needs its own key.

If something goes wrong

• If MEXC asks for “API Usage”: choose “Open API”, not “MEXC-CLI”.
• If you can't tick the futures boxes: skip them; your spot balances still connect.
• If you lose the secret key: create a new key, because MEXC shows it only once.
