Any firm holding client crypto assets for more than 24 hours or with the ability to override client authority would be treated as a regulated custodian requiring a full safeguarding license.

Validators, node operators, and stablecoin issuers face tighter rules, including loss of tech-only exemptions when offering added-value features.

The FCA made clear that arrangements involving smart contracts or decentralization do not place the activity outside regulation.

Stablecoin issuance is considered legal only if the issuer is established in the UK and manages the entire lifecycle.

The FCA's consultation marks another step toward full crypto regulation in the UK.

Firms will be able to start applying for authorization from September 2026.

The FCA plans to consult later this year on DeFi guidance and operational resilience.

The new regime forces all entities providing crypto services to transition from the current money-laundering registrations to a more strict approval regime.

The FCA's guidance requires UK-based stablecoin issuers to control the full lifecycle.

The regulator addressed shadow custody, declaring that if a provider can theoretically override a client's authority, it is officially a custodian.

This could sweep in platforms and software providers that don't consider themselves custodians.

Validators and node operators will lose pure tech exemptions when providing added-value features.

The consultation complements recent Treasury legislation that expands the list of regulated activities.
