Arbiter Less Escrow-Dapp

Arbiter Less Escrow-Dapp is a decentralized application (Dapp) designed to facilitate secure and decentralized asset exchanges between parties through smart contracts, eliminating the need for a third-party arbiter. This Dapp serves as a conceptual framework that can be tailored and enhanced based on specific business logic.

How It Works

Imagine two parties, where Party A possesses valuable assets with a high monetary value and intends to sell them. Meanwhile, Party B expresses interest in acquiring Party A's assets and is willing to exchange them for their monetary assets. Both parties prioritize the security of their assets during the exchange.

This objective is achieved through the utilization of Smart Contracts within the Arbiter Less Escrow-Dapp. Here's a step-by-step guide:

1. Party A initiates the process by creating a smart contract containing the details of the assets they wish to sell.

2. Simultaneously, Party B creates their own contract, locking in the value and ensuring that Party A will be duly compensated during the transfer.

3. After creating the contract, Party B provides the Contract Address to Party A. Notably, only the contract address set by the Party A owner to their contract is permitted to execute the ownership transfer; no other address is authorized.

4. Subsequently, Party A adds their address and the Contract Address of Party B to the respective sections in Party B's contract.

5. Party B then approves the ownership transfer, indicating their intention to take control of Party A's contract.

6. Following the proper setup, Party A executes the transfer from Party B's contract, completing the transfer of ownership. Additionally, the agreed-upon amount is transferred to Party A's address. The transfer functionalities of Party B also mandate approval before execution, ensuring security.

If these steps are diligently followed, the asset transfer will be successful.

Running Locally

Ensure that MetaMask is installed in your browser to run the Dapp successfully.

1. Clone this repository: git clone https://github.com/mdasifahamed/Arbiter-Less-Escrow-Dapp.git

There are two main folders: Dapp, housing the Dapp, and Dapp Test, dedicated to comprehensive testing using Hardhat, Chai, and Ethereum Waffle.

Running the Dapp

1. Navigate to the root directory: cd Dapp
2. Install dependencies for Hardhat: npm i
3. Move to the app directory: cd app
4. Install frontend dependencies: npm i

To utilize the Hardhat Local Blockchain Network or any Testnet via Metamask, refer to this guide.

For a local network, run npx hardhat node from the Dapp root.

Launch the Dapp locally with npm start. Open the provided URL (e.g., http://localhost:3000) in a browser with Metamask installed.

Testing

1. Go to the project root: cd Dapp Test
2. Install test dependencies: npm i
3. Run tests: npx hardhat test

Language And Tools Used

• Solidity for Contracts.
