Everything you might want to know about permanent storage, cost, encryption and what happens if bitty.cat ever goes away.
A permanent file storage service. You upload a file, pay once, and it stays online at a link that does not expire. Files are stored on a permanent public storage network that no single company controls, with Solana used for payment and sign-in.
On Mainnet you pay once, up front, and part of that payment pays the storage network, whose endowment is designed to fund storage for at least 200 years, with no renewal fees. The endowment belongs to the network, not to bitty.cat. Devnet test uploads are not permanent. Copies are held by many independent nodes. We cannot delete or edit a file once it is there.
It depends on file size. You pay once, in SOL, and the app shows the exact amount before you confirm. There are no subscriptions or hidden fees.
Upload is in open beta. Choose Devnet to try it with test SOL — nothing real is spent and test files are not permanent. Choose Mainnet to store a file for real. Mainnet uploads cannot be undone. Beta means we are still improving the apps and may change how they look and work. Files already stored on Mainnet are not affected by app changes.
Not to sign in. You can upload anonymously and receive a secret phrase; keep it safe, because it is the only way to find your files. A wallet (Phantom or Solflare) ties files to your address instead. Either way, storage is paid in SOL.
Not to store a file. The NFT unlocks encryption and the wider bitty.cat ecosystem. Minting one is a small one-time fee shown in the mint app.
Any file type. The upload app shows the current size limit before you start.
No. Permanent means permanent. Our share links can be revoked and expire, but the stored copy stays. Encrypt anything you would not want public.
Your files stay on the public storage network and remain reachable through its public gateways at their permanent address. That is the point of the design.
Only if you encrypt it. Unencrypted files on the storage network are public to anyone with the link or address.
In your browser, before upload, with two layers (AES-256-GCM and XChaCha20-Poly1305) keyed from your wallet signature and your Bitty Kitty NFT. You get a recovery key. We never see the plaintext or the key.
Yes. From my.bitty.cat you can make a share link with an expiry and a view limit, and revoke it any time.
The Bitty Cat ecosystem token. It has its own page.
