The United States Postal Service is the first postal authority to use their ePostage labels and CaseMail‘s non-fungible token (NFT) mail technology for postal purposes.
Documents are cryptographically signed with a unique CaseMail ID, time-stamped, encrypted and recorded on the Blockchain. The documents are immutable and can never be altered.
The initial rollout of the service was exclusively for legal professionals and government agencies with further releases planned to provide global access primarily through integration partnerships with providers of consumer and business services.
There are no cryptocurrencies required with these NFTs and CaseMail tokens are purchased with standard U.S. currency.
