A Cove claim link is a bearer instrument: it encodes everything needed to redeem the deposited funds, and anyone who holds it can claim them. Treat a claim link the same way you would treat cash — if you send it to the wrong person, or post it publicly, the funds can be claimed by someone you did not intend to receive them.

​
What a claim link contains

A claim link is a URL in the form https://cove-cash.vercel.app/claim/<blob>, where <blob> is a compact encoded payload. That payload carries everything needed to authorize the withdrawal:
  • A private spending key — the secret that proves the right to claim the funds. This is what makes the link a bearer instrument.
  • A blinding factor — a second secret required to reconstruct the zero-knowledge proof. Without it, the funds cannot be claimed even if the spending key is known.
  • The token and amount — the deposited amount and which token it is (SOL, USDC, or USDT).
  • Cryptographic commitment data — values that anchor the deposit to its position in the shielded pool, needed to generate the withdrawal proof.
  • The deposit transaction signature — a reference to the original on-chain deposit, useful for verification on a block explorer.
Do not share a claim link publicly or post it in open channels. Anyone who sees the link can claim the funds before your intended recipient does.

​
How to copy your claim link

After a successful deposit, the send page displays your claim link in a read-only field. Click the copy button to the right of the field to copy the full URL to your clipboard. You can then paste it into a private message, email, or any other channel to send it to your recipient.
The send page also shows the full Solana transaction signature below the claim link. You can use this signature to verify the deposit on any Solana block explorer.

​
Finding a link again after closing the page

Cove saves every deposit to your browser’s localStorage before the transaction is submitted. If you close the tab, refresh the page, or the browser crashes after the deposit confirms, you can recover the claim link from the Dashboard.
Before closing the send page, open the Dashboard and confirm that your deposit appears there with a Copy claim link action. This ensures you can retrieve the link even if you lose it later.

​
Single-use links

Each claim link can only be redeemed once. Once a recipient connects their wallet and claims the funds, the shielded UTXO is spent on-chain and the link can no longer be used. Attempting to claim an already-spent link will fail during the on-chain confirmation step.
You can check the claim status of any deposit from the Dashboard. Deposits show a Pending claim or Claimed badge so you know whether a link has been redeemed.
