I created a smart contract that returns created names of those who sent donations to him. On the main page you could see a list of addresses and names. To get there, you need:
1) Install MetaMask wallet
2) Create a wallet and switch from the Ethereum Mainnet to Goerli test network
3) Get some test ethers on your wallet on the Faucet
4) Go eleet.nl/web3, connect your wallet, click Contract info, then Write, input the desired name and press addName
If you are all done correctly and the transaction is confirmed, after a few minutes the address of your wallet will show on the main page. Congratulations!
