SelfTrust | Self-Custody

For Anyone
Bitcoin-first, private, simple, affordable, and trust-minimized.
Self-Sovereign
Non-custodial with sensitive operations (mnemonic, signatures, receiving addresses…) easily verifiable by anyone (no coding skills required).
Immune to typical hardware-wallet attacks
Our suite runs on your own air-gapped device—any Android phone you repurposed (factory reset, no SIM, all radios disabled or removed, inside a Faraday bag)—which is not a prime target for crypto-hackers.
Any Wallet
Recovery and inheritance work with your existing wallets.

True cold storage—safer than hardware-wallets

Invisible to crypto-hackers
By using standard consumer hardware—a repurposed Android phone (see above)—rather than a typical hardware wallet, you are no longer a prime target for crypto-hackers.
Uncompromised Randomness
Your mnemonic is generated via your own physical dice rolls—not via a third-party RNG.
Air-Gapped Signing
Transactions are signed via QR codes anyone may verify—no USB or RFID connection ever—ensuring keys remain offline at all times.

Pass any wallet to your heirs

Secure Splitting
On your repurposed Android phone (see above), your mnemonic is divided into two encrypted parts—one held by your heir, one by any custodian you choose.
Zero Interference
On your passing, your heir receives the custodian's part per your pre-set arrangement and inherits your wallet—without SelfTrust involvement.

Recover any lost wallet

Secure Splitting
On your repurposed Android phone (see above), your mnemonic is divided into two encrypted parts—one held by you, one by any custodian you choose.
Full Control
If you lose your mnemonic, simply request the custodian's part and recover your wallet—without SelfTrust involvement.
