How Arthur Labs uses Blockchains

At Arthur Labs, we've integrated blockchain technology into our Digital Commerce Marketplace to provide secure, transparent, and efficient transaction processing. Here's a detailed look at how we utilize blockchain technology.

Transaction Processing

Receipt Generation

Every transaction in our marketplace automatically generates:

• An immutable blockchain record
• A unique transaction hash
• Timestamp and transaction details
• Buyer and seller wallet addresses

Smart Contract Implementation

Our marketplace uses smart contracts to:

• Automate payment processing
• Ensure secure escrow services
• Trigger automatic releases of funds
• Handle dispute resolution mechanisms

Cryptocurrency Payments

Supported Cryptocurrencies

We currently accept:

• Ethereum (ETH)
• Wrapped Bitcoin (WBTC)
• USDC Stablecoin
• Other ERC-20 tokens

Payment Flow

1. Buyer Initiates Purchase

   • Selects product/service
   • Chooses cryptocurrency for payment
   • Confirms transaction in wallet

2. Smart Contract Processing

   • Validates cryptocurrency balance
   • Holds funds in escrow
   • Verifies transaction completion

3. Settlement

   • Releases funds to seller
   • Generates blockchain receipt
   • Updates marketplace records

Technical Implementation

// Example of our basic transaction smart contract
contract ArthurLabsMarketplace {
    mapping(bytes32 => Transaction) public transactions;

    struct Transaction {
        address buyer;
        address seller;
        uint256 amount;
        bool completed;
        uint256 timestamp;
    }

    function processPurchase(address seller) public payable {
        bytes32 txHash = keccak256(abi.encodePacked(msg.sender, seller, msg.value, block.timestamp));
        transactions[txHash] = Transaction(msg.sender, seller, msg.value, false, block.timestamp);
        // Additional processing logic
    }
}

Best Practices
