How TreasOS works
Cómo funciona TreasOS
Non-custodial treasury OS: the client keeps the keys; TreasOS adds policy, approvals, and audit evidence. Boards get process without handing Bitcoin to an exchange or CASP.
Sistema operativo de tesorería non-custodial: el cliente conserva las claves; TreasOS aporta política, aprobaciones y evidencia de auditoría. El board obtiene proceso sin entregar Bitcoin a un exchange o CASP.
