PRODUCT ARCHITECTURE

Transaction security around the wallet that actually ships.

UTXO Suite is the security layer: SafeSign explains irreversible actions, Security Core supplies reusable analysis and policy, and Academy trains the person making the decision. Vigi Wallet is the final self-custody wallet product that consumes this security model.

PRODUCTS / CURRENT MAPA dark workspace: laptop, phone, external drive and cables side by side.

CORE PRODUCT SYSTEM

Understand before you authorize.

The core remains deliberately small and auditable. It analyzes requests and evidence; it does not become a wallet, hold keys or silently execute transactions.

OPEN →02 / ANALYSIS + POLICY

PRODUCT / ECOSYSTEM BOUNDARY

Vigi Wallet, VigiChain/Vi and Vestige Index are sibling products/systems. UTXO Suite may integrate with them without absorbing their identity or claiming custody/execution it does not own.

UTXO Suite secures the decision. Vigi Wallet owns the wallet.

That separation makes both products stronger: reusable transaction security in UTXO Suite, sovereign multichain self-custody in Vigi Wallet.
