Seal files to a Solana wallet.
This is a test network beta. Use devnet SOL, set your wallet to devnet, and don't send anything you need to keep private: Qapsule isn't audited, and devnet storage is deleted after about 60 days.
Connect your wallet
No Solana wallet found in this browser. Install one such as Phantom, Solflare or Backpack, then reload.
Your post-quantum key
Your browser creates a key separate from your wallet. The private half goes in a password-protected file you keep. The public half is published so others can seal files to you.
If you lose the file or the password, nobody can recover your files.
This wallet already has a published key. Unlock it with your key file.

Send
Public on Solana: your wallet, a hash of the recipient's wallet, the time and the sealed size. The contents and the file name stay inside the seal.
