MEXC portfolio tracker: balances, futures, cost basis, and history

CentraFIN reads your MEXC account with an API key that only has query permissions. You see your spot, your futures and their positions, your open orders, your average cost, and your transfers, next to your other platforms.

What CentraFIN reads

• Balances: your spot account, including what your orders lock up, valued in euros every minute while the dashboard is open.
• Futures: the margin in each currency and your open positions, with their unrealized P&L.
• Open orders: your spot orders, and on futures your limit orders, your planned orders with their trigger price, and your take profits and stop losses.
• Average cost and gains: your spot trades, and your small balances converted to MX. MEXC provides the last month of trades: CentraFIN starts from there, then keeps every new trade.
• Transfers: your deposits and withdrawals, from the last 90 days that MEXC provides and every one after, matched with your other accounts when a transfer goes from one to another.
• Futures history: your fills, your funding, and your closed positions.

Create the key on MEXC

1. On MEXC, open API Management, then create an API key and give it a name.
2. Tick only the query permissions: spot and contract account and orders, deposits and withdrawals, transfers. No trading, withdrawal, or transfer permission.
3. Bind the key to the IP address 130.110.240.91, our relay's address. At MEXC, a key with no bound IP address expires after 90 days.
4. Confirm, then copy the access key (Access Key) and the secret key (Secret Key).

Add it to CentraFIN

1. In the dashboard, open Connectors, then Add a connector, then MEXC.
2. Give it a name and paste the access key and the secret key.
3. CentraFIN asks MEXC for the key's permissions before keeping it. Your balances show up within a minute; your history follows over the next few minutes.

Your security

• A key with any permission that is not a query permission is rejected, as is a key with none at all: only reading gets through.
• The key and its secret key are encrypted as soon as they arrive (AES-256-GCM) and are never shown again: only the end of the access key stays visible.
• All calls go out from our relay, from a single address. If MEXC asks to slow down, CentraFIN stops and waits before resuming.

With your other accounts

Your MEXC futures show up alongside those from Binance, Bybit, and Hyperliquid, and your spot alongside your Coinbase balances. A withdrawal from MEXC to another of your accounts shows up as an internal transfer, not as money leaving. Other platforms: all integrations.

Frequently asked questions

Can CentraFIN trade or withdraw on my MEXC account?

No. The key only has query permissions, and CentraFIN checks with MEXC that it has no other before keeping it.

How far back does my average cost go?

To the last month of spot trades, the period MEXC gives an API key. CentraFIN then keeps every trade, so your history grows from the day you connect the account.

Can I connect several MEXC accounts?

Yes, one connector per account or subaccount, each with its own key and name, up to 12 connectors in total.

Is MEXC tracking free?

Yes. Every integration is included in the Free plan.
