About Satsails

Satsails is a self-custodial Bitcoin and Liquid Network platform that Bitcoin, Lightning, and Liquid. The philosophy of Satsails is to become a platform for everything and anything Bitcoin. Many more features are coming soon!

We are committed to being open source and transparent, offering a non-custodial service for bitcoin and liquid.

Currently our Lightning is custodial and operated by Coinos. This was a decision made to focus on usability. News should be coming soon about other Lightning options

Everything we build is designed to be held and operated by you. We either use on-device technology or connect you to partner companies.

Data Collection

As part of our operations, we collect a unique identifier and register it on our server to allow for account creation and managment. Additionally, we register a public key, which is used solely to direct your fiat payments and ensure that these payments are routed directly to your wallet.

This is the only data we ever collect on our systems.

PIX Metadata

When using PIX for payments, the metadata includes the CPF and the name of the person. This is collected by our partners.
