SeedSigner
- Assemble it yourself from a Pi Zero, a camera, a screen, and a case.
- Air-gapped and stateless. The seed does not stay on the device.
Hold your own keys with confidence. We sit down with you — in person in El Zonte or remotely —
to audit your setup, plan for inheritance and disaster, and stay by your side as your stack grows.
Pay with Bitcoin. Session rates start from the prices below and vary by specialist.
New to self-custody? We’ll get you set up the right way, in person, from start to finish. Together we set up your hardware wallet, generate your seed securely (we never see your seed), and confirm everything works with a live test — so you walk away holding your own keys with total confidence.
Includes:
From $274 — with Bitcoin · rates vary by specialist
A one-time, top-to-bottom review of how you hold your Bitcoin. We look at how your keys were generated, how and where your backups are stored, and where a single mistake or single point of failure could cost you everything — then hand you a clear, prioritized plan to fix it.
Includes:
From $175 — with Bitcoin · rates vary by specialist

Locked out of your Bitcoin? A forgotten passphrase, a damaged device, an incomplete seed, or a wallet you can no longer open — we may be able to help you get back in.

Self-custody, security & business integration
Bitcoin was first introduced into my life in 2016 shortly after completing my undergraduate degree (BComm) from Ryerson University in Toronto, Canada. I ignored it and paid dearly for doing so. Moved to El Salvador shortly before President Nayib Bukele announced he would be making Bitcoin legal tender across the nation. Have dedicated my life to Bitcoin since September 7th 2021, focusing on self-custody, security and business integration. Thanks to Bitcoin I have exited the FIAT system and help others do the same.
Co-founder
I’ve been onboarding Bitcoiners since 2013 and have dedicated my career to making Bitcoin easier to understand, use, and protect. I ran QuickBT in Canada from 2013-2018, welcoming over 90,000 early Canadians to Bitcoin. I co-founded The Bitcoin Hardware Store in 2023 after moving to El Salvador, to create a physical space Bitcoiners could trust to come and explain their most complex questions. If you have questions nobody else can answer, I’m here to help. Book an audit for up to a 90 minute conversation.
Open-source developer
I’m Eric — opensource developer and Bitcoin enthusiast since 2011. I built a suite of free software for Bitcoiners that value sovereignty and trustless systems. Legacy Encryption, Deploy: Deadman Switch and Disrupt are my flagship products. Originally from Austin TX, I moved to El Salvador in 2023. During the day, you can find me surfing or at my cacao finca in the mountains. By night, vibe coding with AI. github.com/ericscalibur
Certified Bitcoin Professional
I have been actively involved with Bitcoin since 2017 and became a Certified Bitcoin Professional (CBP) in 2018. I hold a Bachelor of Commerce and bring several years of professional customer service experience to my role as a Bitcoin Security Consultant at The Bitcoin Hardware Store. I believe Bitcoin security should be approachable and easy to understand, so I focus on providing clear, practical guidance tailored to each person’s experience, needs, and pace, helping them build the knowledge and confidence to secure their Bitcoin themselves.
