Flow of approval of transaction

Developer Discussion
1

Hi team, I’m interested in the process of approving the transfer

  1. Is Fireblocks mobile application necessarily or can we use our own?
  2. API Co-Signer should be created for each owner of the wallet? Or will all transfers sign the API User with the role of Signer that is associated with Co-Signer?
  3. Should the Fireblocks mobile app be installed when adding an Approver to the Co-Signer?
  4. Can i test this flow with the Sandbox workspace?

Hi George, I am Mohammed from Fireblocks.

  1. Yes, fireblocks mobile is necessary if you use the vault structure.
  2. APi cosigner can sign all transactions where the source is a Fireblocks wallet. It depends on your TAP setup and which transaction will be signed by which user.

  3. You cannot test the cosigner on the Fireblocks sandbox.
