Policy Modes

The Virtual Signer supports the following policy execution modes:

• "Always Approve" mode Used mostly for testing. The virtual signer will automatically approve and co-sign all incoming request.
• Approval with API Using the UI, a transaction policy can be deployed in the form of a smart contract. Your virtual will query this transaction policy to determine whether to approve or reject a transaction. Smart contract transaction policies tutorial.
• Approval with Smart Contracts Your virtual signer will expose approve/reject endpoints which can be programatically called to implement your own off-chain policies. REST API tutorial.
