Users that are signatories will be able to sign transactions originating from that account.
Any movement of funds or setting of limits will require a signature. Since the transaction can currently only be triggered from Mesh, the user will also require a role that will allow them access to the required transaction functionality.
Transaction signing is handled automatically by Mesh when the user selects to perform the required action:
Set Limit
Defund Account
Book Trade
Confirm Trade
Transfer Funds
Make Payment
See Manage user permissions for a more detailed overview of the roles that can be assigned to users and the functionality granted to each role.
