If one of the parties involved in a transaction is located in a different country, the Castler digital escrow system can still be used. The system is designed to facilitate secure transactions between parties regardless of their location. The escrow service acts as a neutral third party that holds the funds until the terms of the transaction are met. This means that the buyer can send the funds to the escrow service, and the seller can ship the goods or provide the services. Once the buyer receives the goods or services and is satisfied with the transaction, they can release the funds to the seller. If there are any disputes or issues with the transaction, the escrow service can act as a mediator to resolve the issue. The Castler digital escrow system is designed to provide a secure and reliable way for parties to transact with each other, regardless of their location.
