Find what was
sent to you.
Paste the keys you saved when you made your link. Scanning happens in your browser: your scan key checks each announcement locally, and your spend key never leaves this page. The relayer pays the claim fee so a fresh address never has to spend first.
Hand your scan key to an indexer if you want it to watch for you; it still cannot move funds or tell which payments are yours. Claiming into the Jat pool unlinks the amount you received from your wallet; deposits are fixed-size, so the denomination tier is public. See the writeup.
