How to Deploy

  1. Click on the ‘Deploy’ tab on testnets.wemint.art.
  2. Choose your own ticker and contract name, eg: 'ART' and 'My Art Contract'. Choose the names carefully as they will be on the Ethereum blockchain forever.
  3. Click ‘Deploy!’.
  4. Metamask should bring up a window telling you the Rinkeby gas fees to deploy. If you don’t have Rinkeby ETH, reach out to us and we’ll send you some.
  5. Once you've deployed, you should see a link in the confirmation window. You can also check your contract by going to rinkeby.etherscan.io and entering your wallet address. You should see the contract creation hash and all the details under your profile.
  6. You have now deployed your own custom ERC721 contract on testnet!

How to Mint

Here we describe the easiest and quickest way to mint your NFT.

  1. Create an account on pinata.cloud
  2. Upload your artwork to IPFS on Pinata, by clicking 'Upload' then 'File'.

  3. Wait for your artwork to go through the pinning queue. Depending on the file size, it can take some time for it to pin. Once it's pinned, it'll appear in the list marked 'Pinned'. Your artwork is now on IPFS.

  4. Now you need to create your metadata file. Download this template and use a text editor to edit the name and description, without modifying any of the surrounding code. This is a basic template. To learn more about metadata, read Opensea's Guidelines.

  7. Save your metadata file with a name of your choice, then upload your metadata file to Pinata the same way you did your artwork.
  8. You should now see both your artwork and metadata files uploaded and pinned on Pinata. Your artwork and metadata are now both on IPFS. You're ready to mint!

  9. On testnets.wemint.art, click the 'Mint' tab.
  10. Enter your contract address. You can find it on rinkeby.etherscan.io, as described above.
  11. Click 'Load'.
  12. Enter your metadata URL on testnets.wemint.art. This is the CID of your metadata file plus the prefix 'ipfs://'. You can get the metadata CID from your Pinata page. Remember it's not the CID of the image file, it's the CID of the metadata file!

  13. Enter your preferred royalties if your contract includes the EIP-2981 update. If your contract doesn’t include EIP-2981, you won’t see this option. Remember that EIP-2981 isn’t accepted by the major NFT platforms so it won’t make any difference yet! For now, if you sell on Opensea for example, you can set your royalties there when you swap.
  14. Click 'Mint!'
  15. Wait a bit. Depending on the file size, it can take a couple of hours before you see your art on testnets.opensea.io and rinkeby.rarible.com. You may see a different placeholder image while your NFT is loading (eg: your Opensea profile pic). Don't worry, it just takes time!
  16. Your artwork is now minted and you can list it for sale!
