On Foundation, we are taking a creator-first, community-led approach by having artists select and invite other artists to join the site and mint NFTs. If you make a profile on Foundation, this does not necessarily mean that you are able to mint NFTs. To learn more about how invites work, read this.
Thanks to the internet, an artist can upload, share, and get thousands of likes for a digital artwork—but where can they go to cash in on that virality? We want to live in a world where digital creators have solid options for monetizing their incredible work. That's why we're excited to support digital art NFTs on Foundation.
Once you have received and accepted an invitation to become a creator, you will then be able to create NFTs through Foundation. We’re here to help guide you through the process so you can sell your artwork as unique digital art NFTs and, while you’re at it, cultivate a new collector base.
First, let’s define what a few terms:
NFTs ("Non-Fungible Tokens") are one-of-a-kind tokens that represent a unique good or asset, like digital art. They can be sold in auctions for collectors to bid on or purchase, and the sale of NFTs unlock new revenue streams for creators. Read more about NFTs and how they’re transforming the digital art world on our blog.
Minting an NFT is how your digital art becomes a part of the Ethereum blockchain–a public ledger that is unchangeable and tamper-proof. Similar to the way that metal coins are minted and added into circulation, NFTs are also tokens that get “minted” once they are created. Your digital artwork is represented as an NFT so it can then be purchased and traded in the market and digitally tracked as it is resold or collected again in the future.
How do I mint an NFT?
Once you’re a creator on Foundation and have a wallet with ETH in it, then you can start minting NFTs. We highly encourage all creators to first Twitter verify their profiles before minting.
The NFTs you mint on Foundation will be tied directly to your wallet which means that you’re in control, and you’ll hold and manage your funds directly. Before you get started, you’ll need to make sure you have ETH (the cryptocurrency used for all transactions on Ethereum) and a wallet set up. Check out our guide if you need help setting it up.
Connect your wallet to Foundation.
Head to foundation.app and click “Connect Wallet.”
Your Foundation profile will be activated once you connect your wallet, and then you can add a photo and links to your social media accounts. This is a chance to show your personality and give potential collectors a better sense of who you are.
How do I create an NFT and what are the technical specifications?
You can start the process of minting an NFT by clicking the 'Create' button in the upper-righthand corner.
After, you'll be taken to the "Create an NFT" page. Here you can select between uploading an image in JPG or PNG, or a video file in MP4 format.
Upload a new artwork: Submit a JPG, PNG, or MP4 file that’s no larger than 50MB. For still images, a ~3000px width is ideal. For video, 1080p or 4K is best. Separately, this file will be lightly compressed for display across our website. We’ve found that landscape or square pieces look best on Foundation.
After you've uploaded an artwork, your files will automatically be sent to IPFS (InterPlanetary File System). What does this mean?
Foundation is a non-custodial platform which means we don’t hold your artwork or funds in a centralized server. Instead, all of the artwork is hosted on IPFS, a peer-to-peer hypermedia protocol designed for sharing data in a distributed way. Learn more about why we use IPFS and what it means for creators.
When you upload an artwork, a canonical version is mapped to the token that lives on the blockchain and it can’t be touched or altered. The file itself is then hosted on IPFS to ensure that it will live on forever as well.
Add a title and description: Be sure to include background information, exhibition history, and any other interesting details here. Collectors want to learn as much about your creative practice as possible. Confirm the details of your work before moving on to sign your NFT. Once you mint your NFT, you won’t be able to make any changes.
Why can’t I make any changes to my NFT after I mint it?
Once an NFT has been minted, it exists on the Ethereum blockchain forever. All transactions recorded on the blockchain are irreversible and tamper-proof, this makes the Ethereum blockchain more secure and difficult to manipulate. If you would like to update your NFT, you can burn the token which permanently destroys it. Learn more about burning an NFT here. To avoid the need to burn an NFT, be as careful as possible throughout the minting process.
Got it. Okay, I’m ready to continue minting my NFT.
Mint your NFT: Confirm that the artwork file, title, description are completely accurate. Once you're ready, click the "Mint NFT" button.
Sign your NFT: Your wallet will prompt you to “Sign” the transaction. In the same way that a painter signs a canvas to confirm its authenticity, you can do the same with your wallet. When you sign your artwork, it will forever link the NFT to your unique Ethereum address and wallet, which allows collectors to verify the work is yours—and ensure that you’re always listed as the original artist who receives royalty payments.
Approve gas: A gas fee will need to be approved in your wallet to complete the minting. Gas fees are the cost of interacting with the Ethereum blockchain, they are not fees created or collected by Foundation in any way. Unsure of what this means? Read more about gas fees here.
Wait for your NFT to be minted: After you’ve signed your NFT and paid the gas fee, the minting process begins. While you’re waiting, our smart contract runs code to deploy your artwork to the Ethereum blockchain. If you’d like to view the status of the minting process, click “View on Etherscan” and get a time estimate on when it will be completed.
Avoid double-minting: As you wait for your transaction to complete, we highly advise against attempting to mint the same NFT again or clicking the "Mint NFT" button multiple times. Be patient as your NFT is being minted. Ethereum transactions are processed in the order they are received and your wallet will get backed up with transactions that are waiting to be confirmed if you submit multiple transactions.
Minting complete: Once the transaction has been confirmed, you will now be able to see your minted NFT on your profile.
Congratulations, you’ve successfully minted your first NFT with Foundation!
