Projeto PSI: Sovereign Custody of Digital Assets

Sovereign digital asset custody. Zero Trust in silicon. Post-quantum cryptography (hash-based XMSS signatures). Triple modular redundancy (TMR), derived from aerospace standards.

Why PSI Exists

The era of 'trust the bank' is over. The era of 'trust the exchange' should never have begun. Projeto PSI is born from the radical premise that the custody of your digital assets cannot depend on any institution, any server, or any person — not even the device manufacturer.

While traditional hardware wallets protect against amateur hackers, PSI was architected to withstand state-level adversaries, electromagnetic attacks, physical extortion, and even quantum computers. It is not an incremental improvement. It's a paradigm shift.

Four Pillars of Security

Diagram of PSI hardware defense layers: Faraday shielding, anti-thermal ceramic, and acoustic isolation

Physical Fortress

Armored chassis with Faraday cage against electromagnetic pulses. Anti-thermal ceramic. Acoustic isolation against side-channel attacks. No USB and no screen — minimized attack surface.

Cryptographic key lifecycle: ephemeral reconstruction via SRAM PUF — the key never exists at rest

Key That Never Exists

The private key is not stored — anywhere. It is temporarily reconstructed using the unique silicon fingerprint (SRAM PUF) and collapses after each use. No seed to steal.

Phantom Input Protocol: coercion detection via behavioral biometrics and release of decoy funds under extortion

Smart Anti-Coercion

PSI learns your biometric pattern. If it detects stress or coercion, it activates Phantom Mode: unlocking a phantom wallet with decoy funds. Designed so the aggressor does not notice the deception.

TMR architecture with voter: three processors execute in parallel and a voter validates consensus — aerospace standard

Aerospace Redundancy

Three processors execute each operation in parallel. A "voter" validates the consensus. If a chip fails or is tampered with, the other two continue. A redundancy approach used in critical aerospace systems.

Who PSI Is For

Family Offices & UHNWIs

Personal custody of 7+ digit digital wealth without relying on third parties.

Institutional Funds & Exchanges

Institutional-grade cold storage for qualified custody compliance and auditing.

Governments & Central Banks

Sovereign custody of national digital reserves and CBDCs with resistance to state-level attacks.

The Numbers That Matter

0

Keys permanently stored. Minimized static attack surface.

Triple modular redundancy. Each operation validated by consensus of 3 processors.

Q-Day Ready

Post-quantum XMSS cryptography. Prepared for the day when quantum computers break RSA and ECDSA.

EMP-Resilient

Faraday shielding + ceramic, designed to mitigate electromagnetic pulse (EMP).
