A crypto deposit sends assets from an external address into an exchange-controlled address. A withdrawal asks the exchange to send assets from its custody system to a destination chosen by the customer.
Deposits require exact routing details
The asset, network, address, and any required memo or destination tag must match the exchange’s current instructions. Exchanges commonly wait for a set number of network confirmations before crediting the account.
An exchange status is not the blockchain status
The provider may record internal processing before or after an onchain transaction appears. A transaction hash is the link to the public network record.
A withdrawal includes exchange processing
The exchange may apply limits, security reviews, fees, address allowlists, or waiting periods before broadcasting an onchain transaction. The status inside the exchange and the status on the blockchain are separate.
Some assets require more than an address
A memo or destination tag can identify the customer inside a shared exchange wallet. Omitting it may require manual recovery or make crediting impossible.
