Step 1 — On OKX
Create API key on OKX
OKX USDT perpetual swaps connect through the OKX V5 API. You need three values: API Key, Secret Key, and Passphrase. Withdraw must stay disabled — CRX will reject withdrawal-capable keys.
01Open OKX
Log in to the OKX mobile app or website with the account you want CRX to trade on.
- Use main account unless you use a sub-account
- Complete login + 2FA if prompted
02Go to API settings
Open Profile → Account settings → API (API management). This is where keys are created.
- Profile → Account settings
- Tap API / API management
03Create API key
Tap Create API key. Choose V5 if OKX asks for a version.
- Create API key
- Select V5 when available
04Set purpose & name
Set Purpose to API trading. Name the key something you will recognize (e.g. CRX).
- Purpose: API trading
- Label: CRX or your choice
05Permissions — Trade ON
Enable Read and Trade. Leave Withdraw disabled — CRX rejects withdrawal-capable keys.
- Read — ON
- Trade — ON
- Withdraw — OFF (required)
06Passphrase & copy keys
Set an 8–32 character Passphrase (you will paste the same value in CRX). Copy API Key and Secret Key immediately — Secret is shown once.
- Save Passphrase securely
- Copy API Key + Secret Key
- Complete 2FA if asked
