TrustShop

The problem it solves

TrustShop tackles online marketplace woes: lack of trust, low-quality reviews, and unclear transactions. By rewarding honest reviews with TST tokens on the blockchain, TrustShop incentivizes user participation, promotes product quality, and fosters a secure and transparent shopping experience.

Technologies we used

• Ethereum
• BASE
• Solidity
• Next.js
• Hardhat
• Scaffold-Base
• EAS

How to use it

• Enter the app and add connect your wallet.
• Make sure you have enough ETH to purchase.
• Once you have bought and paid, you will directed to Review Purchases page, where you drop your review and attest.

Our contracts

1. TrustScriptShop contract:

   1. An onchain shop built on base for sellers to sell product and get paid via ETH.
   2. What is unique is that as buyer make a purchase they are redirected to attest what is being bought.
   3. Buyers are immediatedly credited with TST token as a thank you for attesting a product bought.

2. TrustScriptProductReviewAttester contract:

   1. Handles the submission of the review.
   2. Stores attestation as Attestation UID which can be view on base-sepolia.easscan.org.

3. TrustScriptToken contract:

   1. Store of the Token that is being minted after a buyer successfully attest their review.

Future use-case implementation

We would want Attestation to be done after Product has been received hence the satisfaction of a buyer is fully earned, possible the attestion is given a period before the attester is verified to be allowed to attest based on product delivery.

Run the project locally

1. Clone this repo & install dependencies

git clone https://github.com/Okhayeeli/TrustScript.git
cd TrustScript
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

3. On a second terminal, deploy the test contracts:

yarn deploy

This command deploys the smart contracts to the local network. The contracts are located in packages/hardhat/contracts. The yarn deploy command uses the deploy scripts located in packages/hardhat/deploy to deploy the contracts to the network. For the app to work locally you have to allow TrustScriptShop to be a minter from TrustScriptToken contract, you can do so by calling the allowMinter function in the later contract.

Note: When running locally, you should hard-code a bytes32 returned value in attestProductReview within TrustScriptProductReviewAttester because eas.attest does not function locally. For example: return 0x0d455486a3dadeacfba5f340fe5bf84d1f6678b2e2af53536acc8a4274626f82;

4. On a third terminal, start the NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with the smart contracts directly by using the Debug Contracts page, you have to uncomment the page in Header.tsx component in packages/nextjs/components. You can tweak the app config in packages/nextjs/scaffold.config.ts.
