OKX's address whitelist feature allows users to add multiple withdrawal addresses, with each account supporting up to 20 addresses. Users can assign dedicated addresses for different cryptocurrencies and blockchains, with optional notes for categorization. Once enabled, the whitelist protection feature significantly enhances withdrawal security.
Why Use Address Whitelisting?
Address whitelisting is a critical security measure for:
- High-frequency withdrawals
- Multi-wallet management
- Institutional fund distributions
- Separation of cold/hot wallets
This feature restricts withdrawals exclusively to pre-approved addresses, minimizing risks from unauthorized transfers.
Address Capacity and Limits
OKX imposes the following whitelist restrictions:
- Maximum 20 addresses per account
- Shared limit across all currencies/chains
- Requires old address deletion before adding new ones when limit is reached
These limits balance security, system performance, and usability.
