CypherPager is a fully onchain ZK pager, soulbound into the token-bound account of a CypherDude. THE ART IS THE CIPHER: every message is private, encrypted client-side to the owner active-epoch key with BabyJubjub/Poseidon and hidden inside an ASCII grid. Anyone can send; only the CypherDude owner can decipher. Scripts, fonts, the zk prover - everything streams from the Ethereum blockchain.
