"Exodus" may be a fair description of HTC's customer base in recent years – once the reviewers' darling, it has fallen a long way. Earnings for the first half of 2018 were almost half the same period last year (PDF).
So perhaps Exodus isn't the wisest choice of name for its first "blockchain phone". The device is available from today for purchase as a developer preview.
HTC - Exodus - Secure - Enclave - Storage
The HTC Exodus 1 has a secure "enclave", a cold storage wallet for holding the keys to your cryptocurrency, inaccessible to other Android processes. Bitcoin and Ethereum are supported now, although other crypto-tokens will be supported. HTC said that a "Social Key Recovery mechanism" allows keys to be recovered if the phone is stolen. You will need to have mates download a key management app, however.
