Submarine.me

I’m excited to showcase an app I helped build during the ETHDenver Hackathon last week. It’s called submarine.me and it lets anyone—technical or not—upload private, IPFS-backed content that they can lock behind an NFT with a simple share link. Anyone with the link can prove they own the NFT in question and unlock the media. The idea stemmed from the original release of a feature my company, Pinata, calls Submarine. We rolled this feature out last year, and it let people upload media to private storage nodes, generate IPFS content identifiers for verifiability, and share that content with a selective audience. The problem was that individuals and communities wanted to have more complex mechanisms and automation for sharing the media. They didn’t want to have to manually generate a link to the content. For developers, this was no problem. They could write code and implement their own solutions to programmatically generate access tokens for the locked content based on the criteria they set. For non-technical creators, this was a non-starter. We believe submarine.me solves that. Creators simply have to choose how they’d like their media to be unlocked (currently submarine.me only supports NFT unlocking, but more mechanisms will be rolling out soon), provide preview data about the locked media, then upload the media that should be private. When they do so, a simple link is generated. These creators can then safely share that link on Twitter, Discord, Telegram, or anywhere else they want, knowing that unauthorized people will not be able to unlock the content. For those that are trying to retrieve the media, the experience is dead simple. Go to the link, sign a message verifying control of the Ethereum wallet that holds the NFT, and if they do, in fact, have the NFT in their wallet, the private media is returned. If they don’t have the NFT, they are blocked. Excited to see what everyone thinks!

Beautiful. Love it. Question though. On the email you guys said it could unlock memberships, 1v1 meetings etc. How do you foresee that working if the unlock able is just a file? Do you foresee an API or some other types of integrations or just IPFS type files for now?

Awesome! Any plans for making it work with Solana NFTs aswell?

Love it, also just wondering if Fantom will be added as well? Thanks!

Currently support ETH and Polygon...would love to know what other chains people are looking for!

Tell us what you'd like to use Submarine.me for unlocking next:

This looks really cool. Congratulations on the launch!
