VaultChain Security Architecture Analysis

VaultChain: Institutional-Grade Decentralized Custody

VaultChain represents a paradigm shift in decentralized custody. Unlike traditional multi-sig wallets, VaultChain implements dynamic threshold signature scheme (TSS) that adapts based on transaction risk profiles. For small transactions, 2-of-3 threshold suffices. For large movements, the system escalates to 5-of-7 with time-locked delays. The architecture uses MPC to ensure no single party ever holds the complete private key. Security audit by Trail of Bits confirmed zero critical vulnerabilities.
