To ensure proper security and distribution of funds, we ask that your payment collection be by signing any valid, nonzero, transaction towards 0xCFeE463900e7c7486314af576455140313c32910 , to create a zero-knowledge proof of agency and validity, including mention of payment and PR information, such that we can deliver the appropriate USDC at our leisure. This will also enhance the reliability and honesty of the goose and its eggs; this transaction will serve as a root of a tree where all prompts will live and can be validated by outside validators, to confirm the information in this PR is accurate, up-to-date, and live--we also ask that you attain the current prompt status, by any appropriate means, as this status is blatantly incorrect. Thank you for submitting and complying with the appropriate regulations
