Introducing VAPP
The vApp framework introduces a new model for building decentralized applications. It proposes a modular, Rust-based architecture that abstracts away the complexity of proof systems, execution integrity, and interoperability - enabling scalable, secure, and composable apps from a single codebase.

Why vApp
Why vApp
For All
Developers
/ 01
The vApp framework abstracts away blockchain-specific development, letting any developer build decentralized applications using just Rust.
Web3 by Default
/ 02
vApps come with built-in proofs, cross-chain support, and data integrity guarantees. Start building with security, interoperability, and trust from day one.
Internet-Scale
Performance
/ 03
By decoupling application-specific execution from settlement and consensus, vApp gives developers the benefits of Web3 without compromising on performance.

Highlights
The Building Blocks
of Verifiable Applications
A /
Unified Framework
A single Rust-based codebase generates all necessary on-chain and off-chain components — reducing complexity and eliminating code duplication.
C /
Native Interoperability
Cross-chain communication is standardized through modular interfaces that support atomic state updates and trust-minimized bridging.
B /
Verifiable State Integrity
Each transaction follows a structured lifecycle, where state reads, transitions, and writes are cryptographically verified via Merkle-based inclusion/exclusion proofs.
D /
Customizable Proof Systems
Choose from built-in support for zk-SNARKs, STARKs, TEEs and optimistic proofs to optimize for the right balance of speed, trust, and cost-efficiency.
