Do you have any testnet rinkeby in your wallet? It looks like you're getting gas errors.

[lopeselio]

Yes I am having gas errors. I tried obtaining test ether

I am using a new wallet, and I am new to this space

[lopeselio]

Is there a better way to obtain testnet rinkeby in my wallet ?

[lopeselio]

It takes a really long time actually to obtain test ether tokens in rinkeby faucet. Can I try doing this with Ropsten or Kovan test network?

[PatrickAlphaC]

You should be able to get testnet ETH quickly. Kovan might be faster.

Maybe this video would help? I would recommend kovan or rinkeby over ropsten though.

[GoldenRatio3]

For anyone else who needs to change the testnet it's relatively straightforward by

• Updating the 2_mycontact_migration file
• Add the HDWalletProvider to the truffle-config

Kovan testnet does not appear to be supported by opensea for the NFT display Ropsten testnet does not appear to be supported by chainlink for the random number generation
