VaultChain is an agent-native digital sovereignty architecture that integrates Arbitrum Stylus (WASM) and Irys L1 Datachain. It evolves the "Cloud Storage" model into a "Digital Property" paradigm, eliminating recurring subscription fees and centralized censorship.
Built for the March 2026 ecosystem, VaultChain leverages Rust-powered smart contracts to manage permanent data pointers with near-native execution speed.
