How to interact with the deployed contract

You can interact either via:

• Etherscan (write/read contract tab), or
• Foundry Cast from the command line.

Below are example cast commands.

Example: mint WETH (wrap 0.1 ETH)

This calls:

• mint() with msg.value = 0.1 ETH

cast send 0x25dD6C486cD8A9AdC17b5339f830F55f4D6BeC21 \
  "mint()" \
  --value 0.1ether \
  --rpc-url $SEPOLIA_RPC_URL \
  --private-key $PRIVATE_KEY

Example: check your WETH balance

This calls:

• reserves(address user) which returns the WETH balance of user.

cast call 0x25dD6C486cD8A9AdC17b5339f830F55f4D6BeC21 \
  "reserves(address)" 0xYOUR_ADDRESS \
  --rpc-url $SEPOLIA_RPC_URL

Example: burn WETH (unwrap 0.05 ETH)

This calls:

• burn(uint256 amount) with amount = 0.05 ETH (denominated in wei).

cast send 0x25dD6C486cD8A9AdC17b5339f830F55f4D6BeC21 \
  "burn(uint256)" 50000000000000000 \
  --rpc-url $SEPOLIA_RPC_URL \
  --private-key $PRIVATE_KEY
