Unzip

Send any part of a note to any address. A relayer pays the network fee, so the recipient needs no SOL.

Connect a wallet to start

Any Solana wallet works (Phantom, Solflare, Backpack…). It only signs what you approve; its keys never leave it, and Sotto never holds your funds.

  1. 1

    Connect

    Pick your wallet below.

  2. 2

    Unlock

    Create or open your 12-word zip key, kept encrypted on this device.

  3. 3

    Go

    Zip, unzip, speak. Your wallet asks before anything moves.

This is the Devnet preview: set your wallet to Devnet too (Phantom: Settings, Developer settings, Testnet mode, Solana Devnet). On mainnet it shows no balance and warns about the transaction.
