I'm trying to learn about smart contracts. As part of a tutorial I was told to use the "rinkeby" network so I could get some test ether. Using this tutorial -- https://gist.github.com/cryptogoth/10a98e8078cfd69f7ca892ddbdcf26bc, I was told to run

geth --rinkeby

Although I had over 100GB free space on my Mac OS X machine, I quickly ran out of space and still hadn't synced fully with the node. Is there an easier way to connect to the rinkeby network without downloading a full node on my machine? All I want to do is learn about creating a smart contract by running a demo on my machine.

To get Ether on the Rinkeby testnet, just go to http://faucet.rinkeby.io/

You need to make a public post on a social media site with just the address you want Ether sent to, then you paste a link to that post into the site above, and say how much Ether you need.

The reason for the run-around with the social media stuff is to prevent people from getting too much Ether and using it to spam attack the testnet.

  • Yeah I tried taht using -- twitter.com/laredotornado/status/1006271857027354626 but got teh error "No etherum address found to fund." when I pasted that link into the link you lsited above.

  • try posting again as 0x3a58f5f1c5cdb93bb557ec8a472409847d4f4344, that's how addresses are generally formatted, with 0x at the start. Commented Jun 12, 2018 at 2:13
  • Good call. That was the issue.

You can run a light client like Metamask to create an account and interact with the test network.

There is basically an end to end tutorial on how to do this (with Ropsten) here: Mastering Ethereum: Ethereum Basics

The same steps should be easy to reproduce on Rinkeby.
