Escrows on dApp Builder are executed using an open source Ethereum smart contract, typically an Escrow dApp creation process goes like this:

1. A Buyer and a Seller confirm and agree on the terms of a sale of a Seller's product. The Buyer places Ethereum currency into the smart contract - this provides buyer's proof-offunds to the seller.

3. Escrow Agent sees the evidence of shipment and initiates the transfer of the funds stored in the escrow to the Seller. The transaction is now complete.
4. In case if the seller does not produce an evidence of shipment to the Escrow Agent then Escrow Agent returns the funds from escrow to the Buyer. Buyer receives his/her money back.
