Hardened Cold Storage
Industry-grade backup & recovery for Bitcoin & self-custodied crypto wallets
Simply secure. Quantum resistant.
Crypto Security Tools
We build offline-first tools that protect digital assets... upholding self-custody principles while amplifying security and privacy.
Whether you're safeguarding your own crypto or supporting others, our solutions deliver trusted control without online exposure, third parties, or legal complexity.
Today’s wealth isn’t just physical. It lives in private keys, seed phrases, encrypted files, and credentials — many of which lack a clear path for handoff or continuity. NFT's (Non-Fungible Tokens) and RWA's (Real World Assets) are becoming more widely used in the Digial Ledger Technology (DLT) space.
Our tools help solve that. Whether you're a financial advisor, estate planner, or privacy-focused company, organization or individual, we offer workflows that preserve security and control and support a long-term digital continuity plan.

Who We Serve
Trust & Estate Attorneys
Professionals who draft wills, trusts, and powers of attorney — but often lack secure, standardized tools for helping clients manage and transfer self-custodied digital assets.
Professional Fiduciaries
Individuals or firms legally appointed to manage another person’s assets — typically through a trust, court order, or legal agreement — and tasked with acting in their client’s best interest.
Executors & Estate Administrators
Appointees named in a will or by a court to handle posthumous asset access, distribution, and recordkeeping — now facing the challenge of locating, unlocking, and transferring digital assets securely.
Corporate Trustees
Bank or law firm–based trust departments that manage complex estates or high-value holdings — increasingly including digital assets with no built-in continuity protocols.
How It Works
1. Create Your Backup
Launch the EncryptFire app on any desktop or laptop — no installation, no internet required. Generate your offline backup in minutes.
2. Split & Protect
Break your backup into secure, password-protected pieces. Store them across multiple USB drives, with optional timed cloud access if needed.
3. Enable Continuity
Use our structured handoff process to prepare digital assets for the future — whether for personal peace of mind or to support clients and beneficiaries.
