Welcome to CLAIMA.
CLAIMA is a Solana toolkit for sending value behind a password-protected URL. The sender locks SOL in a one-time vault, the recipient unlocks it with a shared secret — no recipient wallet address required at send time.
What CLAIMA is
A small set of routes that lets anyone on Solana create or claim password-protected drops. There's no account, no server, no custodial wallet between you and the network.
When you create a link, CLAIMA generates a fresh ephemeral Solana keypair, encrypts its secret key with your password (PBKDF2 → AES-256-GCM), and writes the resulting payload to the URL fragment — the part after # that never reaches our server. The recipient enters the password in their browser, the keypair is recovered locally, and the temp vault signs a transfer to the recipient's wallet.
Why it exists
The classic Solana transfer requires you to know the recipient's wallet at send time. That's a friction point for gifts, perks, payroll, support payments, community drops, and anything where the two parties haven't exchanged addresses yet.
CLAIMA turns the transfer into a claim: the sender funds a vault, the recipient proves intent with the secret, and the wallet handoff happens only at the moment of claim.
Who it's for
- Crypto-native users who want to airdrop SOL to a friend who doesn't want to share their wallet publicly.
- Community managers running quests, raffles, or bounty payouts where the winner is decided later.
- Developers who want a non-custodial reference for how to combine WebCrypto, fresh keypairs, and Solana transfers.
