Paid wallet verification
The Premium gatekeeper checks whether the connected wallet has activated access before Chat On-Chain is loaded.
HyperFNB Premium protocol
Private conversation with verifiable on-chain delivery.
Chat On-Chain is the paid-wallet communication layer inside HyperFNB Premium. It binds messaging identity to a wallet, encrypts message content before delivery, and uses HyperEVM events as a verifiable transport record.
What happens when a paid user opens chat.
The production feature is separated from the legacy offline prototype. Access, identity, encryption, delivery, and history each have a defined boundary.
Signed Premium session
The wallet signs a short-lived session challenge so protected server operations can verify ownership without holding a private key.
Messaging public key
A wallet-bound public identity key lets participants derive an encrypted communication route.
Client-side encrypted content
Message content is encrypted with authenticated encryption before it is sent to the HyperEVM delivery layer.
HyperEVM event record
The encrypted payload is dispatched through the configured contract and produces a verifiable event tied to the sender and channel.
Encrypted conversation history
Clients reconstruct the conversation from encrypted events and decrypt only when the required identity material is available.
Security boundaries
On-chain delivery does not mean public plaintext.
The blockchain transport can make delivery verifiable while message content remains encrypted. Metadata inherent to public-chain transactions—such as sender, time, contract interaction, and transaction cost—may still be observable.
What users must verify
- The connected wallet and HyperEVM network are correct.
- The production gatekeeper and messaging contracts are the reviewed deployment addresses.
- The recipient identity key belongs to the intended counterparty.
- No seed phrase or private key is ever entered into HyperFNB.
Encryption reduces content exposure but does not remove blockchain metadata, compromised-device risk, contract risk, or the need to verify counterparties.
Premium access
One paid-wallet activation unlocks both operator-grade tools.
Chat On-Chain and FNB Operator share the same Premium wallet-access boundary while keeping their feature logic separate.
