## Non-Custodial Security Models

Non-custodial security models are architectural frameworks where the user retains full control over their private keys and assets, without relying on a third-party intermediary. This model shifts the responsibility of security from the institution to the individual.

In this environment, consent management is not just a feature but a survival skill. Users must understand the risks of the protocols they interact with and the permissions they grant.

These models rely on the user's ability to securely manage their credentials and understand the technical implications of their on-chain actions. Security in a non-custodial model is built on layers of defense, including cold storage, hardware security modules, and robust wallet permissioning.

It is the ultimate expression of financial self-sovereignty. However, it also requires a high level of technical literacy and vigilance.

The ecosystem is continuously developing tools and interfaces to make this model more accessible and safer for the average user, while maintaining the core principles of decentralization.
