Device number limit

To help maintain a wallet performance, each wallet is limited to 10 devices. If you reach this limit, you can disable old or unused devices using this endpoint.

​
Overview

The Fireblocks Embedded Wallet (EW) solution allows multiple devices to perform actions using the same wallet, such as signing transactions and running takeovers. This lets you support a multi-device, multi-platform seamless digital experience and enables an end user to use their account on any of their devices.

​
Definitions

Let us define the following two types of devices for a multiple-device wallet:
  • Requesting device: A new device that wants to join the wallet.
  • Approving device: The device in the wallet that can already run operations, like signing transactions; for example, the device you generated key shares with.

​
Supported functions

Two functions in the EW SDK interface support multiple devices:
  • requestJoinExistingWallet: A function in the requesting device that receives a handler that emits events according to the progression of the process. Specifically, the function emits requestId, the UUID used to approve the request.
  • approveJoinWalletRequest: A function in the approving device that receives a requestId and will allow the processing of the approval to start.
