# Security ## 🔐 Wallet Creation & Security Caishen's wallet infrastructure is built from the ground up with **user sovereignty and security** at its core. While inspired by modern cryptographic techniques, we intentionally avoid disclosing implementation specifics to reduce attack surface awareness. *** ### 🚫 No Centralized Private Key Storage Caishen **never stores complete private keys—anywhere**. Our architecture ensures that no single system, service, or entity can ever reconstruct a user's full private key independently. *** ### 🧩 Key Sharding and Secure Assembly Wallet keys are generated using a **secure, distributed process** and then cryptographically split into multiple independent **key shares**. These shares are distributed across multiple trusted factors, which may include: * User-controlled elements * Device-resident data * Confidential authentication vectors *** ### 🔐 Threshold-Based Access To use a wallet for a transaction: * A **minimum threshold of shares** is required * Shares are **securely reassembled just-in-time** * The key only exists **ephemerally**, during the operation * Nothing is stored or cached after use *** ### 👤 Self-Custodial by Design Caishen is designed so that: * **Only the user or agent** can trigger key reassembly * Even with backend access, **no one (including Caishen)** can unilaterally recreate or use a private key * All wallet actions are initiated and approved **by the user or agent** exclusively --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
