In decentralized finance and autonomous protocols, proxy upgrade keys are often the most fragile attack vector. Centralized admin keys, compromised multisigs, or hijacked owner accounts have caused billions in protocol drains. TrustWard replaces human admin keys with an autonomous, validator-enforced upgrade safety pipeline. Protected targets delegate upgrade authority exclusively to TrustWard. When an upgrade proposal is submitted, GenLayer validators non-deterministically fetch the commit-pinned baseline and candidate source codes directly from GitHub, execute multi-tier dragon firewalls (storage layout ordering, guard authority preservation, value movement safety, and governing charter compliance), and dispatch bytecode slot mutations only after strict consensus approval and challenge window closure.
