Could you build this?

Partial The client UI and standard cryptography can be vibe-coded, but integrating secure on-chain cryptographic email protocols with Stellar smart contracts/transactions and decentralized storage requires specialized Web3/crypto expertise.

What it would actually take: The architecture requires client-side asymmetric encryption (e.g., NaCl/libsodium or Web Crypto) coupled with Stellar Soroban smart contracts or native Stellar memos for delivery verification, micro-payments ('postage'), and access policies. Off-chain storage like IPFS or encrypted relays must handle large message payloads. The difficult aspects are ensuring end-to-end cryptographic privacy without metadata leakage on a public ledger, handling key discovery/revocation, and managing zero-gas transaction relaying.
