Each Bitcoin transaction we receive is linked to specific Payment. In most cases each transaction results in state transitions of the Payment.

In scenarios when our system decides that the transaction is suspicious the Payment will remain in intermediate step UNCONFIRMED until the transaction is settled on the Bitcoin blockchain with high certainty.

For each payment and transaction we analyze it's risk depending on multiple factors, one of which is the value of the Payment.
