Guys, just in case🥳
If you're seeking a secure way to facilitate transactions, consider our Escrow service. We have been providing this service for nearly two years now. For more details, see below.

We serve as a neutral intermediary between two parties. When a client commissions a developer for a task, they entrust their funds to us. Once the work is completed and meets the client's criteria, the funds are released to the developer. If not, the funds are either returned to the client or we intervene to assist in resolving the issue.

Futhermore, we have a Feedbacks room with comments from previous clients which also includes the conditions. Don’t hesitate to use the contacts below. Have a great day
