Changes to Deposit and Withdrawal API to Support Multiple Blockchains

A quick update that we are currently planning to introduce multiple blockchain (network) support for currencies in Q3 2022, allowing our clients to deposit or withdraw funds flexibly – and at a lower cost. In anticipation of this new feature, we will be making the below changes to the API.

New networkparameter to be added to the following REST API endpoints:

  • POST /user/requestWithdrawal
  • GET /user/depositAddress
  • GET /user/minWithdrawalFee

The network parameter will be used to indicate which blockchain you would like to deposit or withdraw from. The acceptable value in the network parameter for each currency can be found from networks.asset from GET /wallet/assets

The new networkparameter will be created on 11 August 2022 for your integration and testing. This parameter will initially be optional and if unspecified, the default network will be assumed to be btc for XBT and eth for all other currencies.

The parameter will be made mandatory subsequently and you will receive an error message network must be provided if the network field is omitted or invalid network if the network value is invalid, and your request will not be processed. 

Please refer to the dates below to ensure that you can continue to use BitMEX services without any disruption.
