Airstack - Obtaining Transaction History Data

We used Airstack to obtain transaction history data, including ERC20 and NFT trade information, royalty fees, royalty fees' USDC value and NFT images. The integration of GraphQL with Airstack made it easier to work with the data.

LENS PROTOCOL- Attaching Additional Information to Wallet Addresses

To attach more information to wallet addresses, we utilized LENS PROTOCOL. We were able to retrieve image and bio information through a GraphQL client, which made the transaction information more human-readable.
