In the 1990s, governments tried to ban strong encryption.

Most Lightning wallets blur the line on custody.

In the latest blog from the VLS Project, Greenlight stands out as the model that lets builders offer Lightning access through apps or wallets without giving up control.

⚡️ Node ops in the cloud, signing on-device.

Built on Core Lightning and powered by the VLS Project, Greenlight shows how to implement Lightning infrastructure without custody risk:

✅ Professionally managed nodes

✅ Validated signing on user devices

✅ APIs for wallets and services to go self-custodial
