Test DEX

Interacting with the DEX

A Decentralized Exchange (DEX) allows users to swap tokens directly from their wallets, provide liquidity, and earn fees. To use the DEX:

1. Connect Your Wallet: Use a wallet like MetaMask or Rabby to connect to the DEX Interface.

2. Swap Tokens:

   • Select the token you want to swap from and the token you want to receive.
   • Enter the amount and review the estimated output.
   • Approve the token if required, then confirm the swap.

3. Provide Liquidity:

   • Go to the "Liquidity" section.
   • Select the token pair and amounts to deposit.
   • Approve both tokens if necessary, then supply liquidity.
   • You will receive LP (Liquidity Provider) tokens representing your share.

Querying DEX Data with the Subgraph

The subgraph indexes on-chain DEX events and exposes them via a GraphQL API for easy querying.

1. Access the Subgraph:

   • Use the Subgraph Endpoint

2. Example Queries:

   • Fetch Recent Swaps:

     query {
       swaps(first: 5, orderBy: timestamp, orderDirection: desc) {
         id
         sender
         amount0In
         amount0Out
         amount1In
         amount1Out
         timestamp
       }
     }

   • Get Liquidity Pool Stats:

     query {
       pairs {
         id
         token0 {
           symbol
         }
         token1 {
           symbol
         }
         reserve0
         reserve1
         totalSupply
       }
     }
