Connect MEXC to dca.bot (Secure, IP-restricted API key)
In this step-by-step guide you’ll create a restricted API key on MEXC, lock it to dca.bot’s IP, and paste the credentials into your dca.bot account. The process takes just a few minutes and does not require withdrawal permissions—dca.bot only places and manages spot trades on your behalf while funds remain in your MEXC account.
Before you start
A verified MEXC account (spot trading enabled).
An active dca.bot account open under Exchanges → MEXC in another tab.
Two-factor authentication (2FA) available for MEXC (recommended).

Create & restrict your MEXC API key
1) Go to MEXC API Management. Sign in to MEXC and open API Management from your account menu.
2) Set the exact permissions. In the permission grid, enable:
• Account → View Account Details
• Trade → View Order Details and Trade
3) Name the key. In Notes, type dcabot so you can easily recognize this key later.
4) Lock the key to a single IP. In Link IP Address, add:3.74.82.155
This allowlist ensures your key only works from dca.bot’s infrastructure.
5) Acknowledge the risk reminder. Check I have read and agree to the Risk Reminders for API Users.
6) Create the key. Click Create, then complete any Email code and 2FA challenges MEXC requires.
7) Copy the credentials—shown once. MEXC will display your API Key and Secret Key a single time. Copy both values now and store them securely.
Connect the keys in dca.bot
Return to the dca.bot tab and choose MEXC under Exchanges. Paste the API Key into the API key field and the Secret Key into the Secret field, then confirm the connection. Once connected, you’ll see your spot balances for supported pairs and can start or edit your DCA strategies.

Troubleshooting (no guesswork)

“IP not allowed” → Confirm
