Coin Escrow P2P Platform Development Requirements
Budget: $750 – $1,500 USD
Coin Escrow P2P Platform Development Requirements (Simplified Version)
1. Purpose
Provide a platform that allows buyers and sellers to trade safely using cryptocurrency escrow.
The buyer deposits coins into the platform escrow wallet. After the seller delivers the service/product, the buyer approves the release, and the coins are transferred to the seller.
If a dispute arises, the platform administrator manually arbitrates the case.
2. Basic Transaction Flow
Transaction Creation
The buyer creates a transaction form by entering:
Transaction title / description
Contract amount (e.g., USDT)
Deadline (due date)
Additional conditions (optional)
The buyer deposits the contract amount into the platform escrow wallet.
The seller reviews the transaction details and accepts.
Transaction Process
The seller provides the service/product.
The buyer confirms completion and clicks “Approve” → Coins are transferred to the seller.
The seller only pays the blockchain network transaction fee.
If the buyer does not approve and the deadline expires, the transaction automatically moves to “Dispute Possible” status.
Dispute Handling
When a dispute is raised, the transaction enters “Dispute” status.
A chat + timeline view is available where buyer, seller, and platform admin can all see the discussion and evidence.
The platform admin makes the final decision to refund the buyer or release payment to the seller.
