The team describes a system that proves a payment is within the spending limit while keeping the actual amount private, fixing a prior spending limit check review payments amount issue on chain. They also mention a script that runs the end-to-end process in four simple steps: witness-generated, proof-created, proof-verified successfully, and completion shown on the video. The verifier contracts connect directly to existing spending limits on Stellar for private spending enforcement for real users."}
