This detail is required for crypto which uses Destination Tag technology, such as Ripple (XRP), Stellar (XLM), Cosmos (ATOM) etc. When you deposit crypto to your OKX portfolio, you must enter the designated memo or tag, in addition to the deposit address.

On-chain deposit logic: Our platform is a centralized exchange, so when you deposit funds to your account address, they will only be credited once it meets the required aggregation conditions.
