Ideate phase

Students brainstorm the specific steps required to write data to Uniswap’s smart contract by executing a token swap or similar transaction:

• Connection to Ethereum Node: Review node access (Infura, Alchemy, or local node) and setting up Web3.js or Ethers.js for transaction capabilities.
• Configuring Wallet Permissions: Guide students through configuring their wallets to approve transactions securely.
• Define Contract Functions for Data Writing: Identify and discuss functions in the Uniswap contract, such as swapExactTokensForTokens , that are used to initiate transactions.

Prototype

• Implementation:
  • Students write code to connect to the Uniswap contract and send data to execute a token swap.
  • Configure and manage gas fees for the transaction, ensuring it completes on the blockchain.
• Verification and Reflection:
  • Verify transaction success by checking transaction hashes on a blockchain explorer (e.g., Etherscan).
  • Reflect on transaction costs and discuss how to manage gas fees effectively, considering different network conditions.
