We are extremely excited to announce our acquisition of Specter Solutions, a leader in self-custody solutions for Bitcoiners. Today, alongside the Specter Solutions team, we are launching Specter Labs, a division of Swan that expands our alignment with Bitcoin principles by focusing on open source and privacy-oriented tools that help Bitcoiners secure their holdings in the best way possible.
“Do the best thing for Bitcoin and Bitcoiners, ” has always been Swan’s guiding principle. Our mission is to convert the next ten million Bitcoiners and walk with them on their journey to freedom, prosperity, and self-sovereignty.
In the last three years, Swan built one of the industry’s best education and product teams and grew a successful platform for onboarding individuals, corporations, trusts, IRAs, financial advisors, and employers to Bitcoin. Our free and automatic withdrawals encourage self-custody, our automated savings plans develop long-term thinking, and our ongoing education helps people understand the value of holding their Bitcoin keys.
The launch of Specter Labs will give Swan customers end-to-end services on their Bitcoin journey from complete beginner to self-sovereign Bitcoiner by providing deep integrations with Specter’s leading self-custody solution and other tools over time.
It is important to us that the Specter project remains open source, so we are establishing clear guidelines and principles. Swan will provide engineering support and some product direction. Specter’s open source desktop project does not, and will not have any default network connections to Swan or customer identification (KYC) features. Specter does not and will not track users in any way unless they opt into features that are clearly labeled integrations.
The Specter desktop client will continue to be usable with complete independence from Swan, or in conjunction with it, per the user’s preference. The Specter Desktop wallet shall remain an open source project under the existing MIT License.
We look forward to partnering with the Specter team to deliver the industry’s best end-to-end Bitcoin journey.
Here’s to building a bright orange future,
