A closer look

Plan the details of your product.

The questions teams ask us before a first call.

Not covered here?Bring your question to a demo with our team.
Does an asset have the same address on every network?

No. Asset and network configuration belong together. The customer deposit journey should show the selected network and the address associated with that product.

What is the role of crypto screening?

Screening supports the review of digital-asset activity. It is distinct from custody and transfer execution, and must be connected to the relevant operating policy.

How is slippage protection used?

The crypto-exchange product can use slippage protection around quote execution. The available behaviour and settlement conditions depend on the selected integration.
