Quick start.

You need:

• A Solana wallet (Phantom, Solflare, or any wallet that supports the Wallet Standard).
• A small amount of SOL to lock plus the network fee (~0.000005 SOL per signature). For testing, get free SOL from solfaucet.com.

1. Go to /c/new and connect your wallet.
2. Pick an amount — e.g. 0.05 SOL.
3. Set a password at least 8 characters long. The strength meter shows red/orange for weak, blue for strong.
4. Optionally add a note the recipient will see after unlocking (it's encrypted, only they can read it).
5. Click Lock & generate link →, confirm the transaction in your wallet.

You'll see a success card with the URL, a QR code, and share buttons.

Send the URL and the password through two different channels. Same channel = same threat model as sending a plaintext key — anyone who intercepts the message can claim.

Good patterns:

• Link in a tweet / Discord DM, password in a voice call.
• Link by email, password by SMS or in person.
• Link on Telegram, password through Signal.

1. Recipient opens the URL in any modern browser.
2. They see a card with the locked amount and (after decrypt) the note.
3. They connect their own Solana wallet.
4. They type the password and hit Unlock & claim →.
5. The vault drains to their wallet in a single transaction. The recipient doesn't need to have any SOL — the fee comes out of the locked balance.

The success screen has a View tx ↗ button to Solana Explorer. You can also open /c/mine on the sender's device — the link's status flips to claimed once the vault balance hits zero.

If you prefer the CLI for a sanity check:

solana balance <vault-pubkey> --url devnet
# 0 SOL means the vault has been drained.
