SimpleX Chat is an instant messenger that is decentralized and doesn’t depend on any unique identifiers such as phone numbers or usernames. Users of SimpleX Chat can scan a QR code or click an invite link to participate in group conversations.

AFAIK it is audited, and its threat model is rather extreme, like there is no unequivocally binding id, you can give every contact a different id
