Prepare one tester PayLink
Create and fund one isolated Arc Testnet escrow, then download its single-use private recipient package. Your browser wallet signs both transactions; Arc PayLink never receives its key.
Connect a funded Arc Testnet wallet to prepare one private tester package.
Testnet only. Never post the downloaded package publicly; whoever holds it can claim that one escrow.
