Progressive Security

custody.progressive-security

Progressive security is a wallet design approach that starts with low-friction key management for smaller amounts and guides users toward stronger schemes as value, experience, or threat exposure grows. It treats hardware signing and multi-key setups as staged upgrades instead of one fixed wallet architecture from day one.
