Security

Trust less.
Verify more.

Security is a system boundary, not a slogan. sha.chat combines end-to-end encryption, user-controlled wallet keys, post-quantum primitives and isolated ZVM execution.

Development status

Target architecture · Not yet independently audited · Beta software should not hold material funds

01

End-to-end encryption

End-to-end encryption keeps private messages readable only by conversation participants.

Core architecture
02

User-controlled wallet

Wallet control stays with the user, with explicit review before signing or sending.

User control
03

Post-quantum transactions

ML-KEM-512 key establishment and ML-DSA-44 signatures secure transactions and agent-to-agent workflows.

04

Isolated ZVM nodes

Sensitive ZVM nodes are sha.chat's security fingerprint: execution stays separated from the mobile client behind controlled, verifiable boundaries.
