When someone pays you through Cove, they share a claim link instead of asking for your wallet address. You open that link in a browser, connect any Solana wallet, and click one button to receive the funds. The Cove relay handles the on-chain transaction and pays the fee, so you need no SOL in your wallet to complete the claim.

​
What a claim link looks like

Every Cove claim link follows this format: 
https://cove-cash.vercel.app/claim/<base64url-blob>
The blob at the end is a Base64url-encoded JSON payload that contains everything needed to unlock and withdraw the funds — the spend key, the blinding factor, the amount, the token mint, and the cryptographic proof data. Because the link itself carries the secret, you can open it in any browser without logging in or creating an account.
A claim link is a bearer instrument. Anyone who has the link can claim the funds. Treat it like cash — do not forward it to untrusted parties and do not share it publicly.

​
What you need to claim

  • Any Solana wallet supported by the wallet adapter: Phantom, Solflare, or Backpack
  • A browser with that wallet extension installed
  • No SOL — the Cloak relay submits the withdrawal transaction and pays the network fee on your behalf

​
Key properties of claim links

  • Single-use — once the nullifier is spent on-chain, the link cannot be reused. Any attempt to claim a second time will fail.
  • Bearer instrument — possession of the link is sufficient to claim. No password or account is required.
  • Relay-powered — the Cloak relay submits the transaction to Solana and pays the fee, so your wallet balance does not need to cover gas.
  • Privacy-preserving — your wallet address is not linked to the sender’s wallet on-chain. The sender and recipient remain detached.

​
Zero-fee claiming

The Cloak relay covers the Solana transaction fee when you redeem a claim link. Your wallet receives the full amount shown in the link with no deduction for gas. You only need a wallet — not a funded one.
If the relay is unavailable, the UI may fall back to a mode where your wallet signs and submits the transaction directly. In that case a small network fee will be deducted from your wallet balance.
