Payments between Ukraine and Canada clear when the paperwork answers the questions both banks will ask: the payment's purpose, the contract or invoice behind it, the parties' identities, and the currency-control layer where rules apply. LexRoota coordinates the document set around each payment — contracts, invoices, purpose evidence, and the NBU-rule paperwork on the Ukrainian side — so wires move on documents instead of on explanations after a hold. Current rules are assessed per payment, in plain terms.
