Ethereum 101
This quest is an introduction to the basics of Ethereum on the Goerli network.
The Goerli network is an Ethereum testnet, meaning your ETH has no real value. The network is just used for testing.
To start, make sure you have some Goerli ETH. Click the button below to get some ETH sent to the address we've created for you, .
You have ETH on the Goerli testnet. Now, try sending us some ETH (technically, you're sending ETH to a smart contract we've deployed).
Be patient, block times are usually around fifteen seconds and may be longer.
So far, you've sent us ETH.
Note that you spent more than 1 ETH since you had to spend some ETH on gas — think of it like a transaction fee.
Now, get your ETH back.
Note that you got less than 1 ETH since the smart contract needed to spend some ETH on gas to get your balance back to you.
Now, send some data with your transaction. Enter some text below for it to be saved on the blockchain forever. Note that each character you store will cost extra ETH.
You saved "0" on the blockchain.
