Charles Hoskinson told Consensus 2026 this week that users should probably never manage their own private keys. The Cardano founder argued smartphones' built-in security chips outperform Ledger and Trezor hardware wallets for everyday crypto transactions, calling the current self-custody model a bottleneck for mass adoption.
Why Phones Work Better
Most people already carry stronger security in their pockets than dedicated crypto hardware offers. Hoskinson noted Apple's Secure Enclave isolates sensitive data even if a phone's main system is compromised. Android's Keystore and Samsung's Knox systems work similarly with hardware-backed keys. They use biometrics like Face ID instead of seed phrases users keep losing or photographing. The friction of separate devices and companion apps is exactly what mainstream users reject.
Passkeys Go Mainstream
FIDO reported 5 billion active passkeys globally as of May 7. Three-quarters of consumers now use at least one. This shift matters because users already trust device-bound credentials for apps and websites. Coinbase's smart wallet proves it works for crypto too—it onboard users without recovery phrases using Apple or Google passkeys. The tech creates non-exportable keys in the phone's secure hardware. Trezor's newer models finally include secure elements, but they still require an extra device.
When Hardware Still Wins
Dedicated wallets have one real advantage: their own secure screens. That matters when verifying transactions if a phone or laptop is compromised. For larger holdings or users needing the strongest threat model, this isolated display is worth the hassle. Hoskinson admitted as much while describing Samsung's Knox work profile as 'a separate operating system, separate circuits in the hardware.' Still, for routine purchases and small balances, phones are more than adequate. The key insight? Most crypto users already have better signing hardware than they realize.
Industry focus now shifts to building services that leverage existing phone security. Expect more platforms to follow Coinbase's lead with passkey-based onboarding.
