PROVEN PROCESS
Our Development Methodology
Our systematic approach to Non-EVM fraud proof development ensures security, reliability, and rapid deployment for your Layer 2 or optimistic rollup.
01
Architecture & Design Review
We begin with a collaborative design phase, mapping your fraud proof logic to the target non-EVM environment (e.g., Cairo, Move, Solana). We define the challenge period, state commitments, and dispute resolution flow to ensure correctness from day one.

Requirement Alignment
02
Secure Implementation
Development follows formal verification principles where possible. We write contracts in Rust, C++, or the native language, implementing fraud proof logic, state transition verification, and bond slashing mechanisms with zero trust assumptions.

Rigorous Testing & Simulation
We deploy a local testnet to simulate adversarial scenarios, including invalid state transitions, malicious validators, and network delays. Our property-based testing ensures the fraud proof catches all invalid claims.

Audit Preparation & Deployment
We prepare comprehensive audit packages for firms like Trail of Bits or Quantstamp, including technical specifications and test suites. We then manage the mainnet deployment and validator onboarding process.

Fraud Proof Development FAQs
Get clear answers on timelines, costs, and technical specifics for your custom Non-EVM fraud proof system.
A complete, audited fraud proof system typically takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture and design, 2-3 weeks for core development, 1 week for internal testing, and 1-2 weeks for a third-party audit. We deliver in sprints with weekly demos.
