Live Interaction Examples

1. Set Data
   Update the stored number on the Sepolia Testnet:

   cast send 0x986e9dbc23e5921ec9455d3be21bf821489c2 "setNumber(uint256)" 108 --rpc-url <INFURA_URL> --private-key <PRIVATE_KEY>

2. Get Data
   Retrieve the stored number:

   cast call 0x986e9dbc23e5921ec9455d3be21bf821489c2 "getNumber()" --rpc-url <INFURA_URL>
