WhyTx

WhyTx is a private memory and proof layer for crypto transactions. It lets users connect a wallet, import a real Monad transaction, attach private context such as its purpose, category, counterparty, follow-up date and status, and secure a salted Merkle-root commitment onchain while the readable record stays encrypted locally. Users can later track unresolved payments, create append-only versions, selectively reveal individual fields and let anyone verify that the revealed information matches the original onchain commitment. WhyTx solves the problem of wallet histories showing what happened while losing the human reason behind a transfer. During development, I learned how to combine encrypted client-side storage, deterministic record hashing, field-level Merkle proofs, append-only smart-contract versioning, Reown wallet sessions and reliable Monad Mainnet/Testnet deployment.
