StarkNet ZK-Proof Achievement Verifier

We architect and deploy custom verifier contracts in Cairo 1.0, leveraging StarkNet's native language for maximum efficiency and security. Includes gas optimization and comprehensive unit/integration testing.

Seamlessly integrate STARK proofs generated off-chain. Our system handles proof verification, state updates, and event emission, ensuring data integrity with cryptographic guarantees.

Connect your verifier to trusted off-chain data sources via decentralized oracles (e.g., Chainlink) or custom API endpoints with signed attestations for tamper-proof inputs.

We implement batch verification and state compression techniques to minimize L1 settlement costs, providing predictable and reduced gas fees for your users.

Every verifier undergoes rigorous security review, including manual code audits, formal verification where applicable, and testing against known vulnerability patterns.

We provide automated deployment pipelines to StarkNet testnet/mainnet and set up monitoring dashboards for proof volume, verification success rates, and system health.

ZK-verified achievements create immutable, trustless proof of skill, increasing player investment and average session time by up to 40%.

Eliminate fraud in tournaments and leaderboards. Our verifier ensures only legitimate achievements mint NFTs or trigger rewards, backed by StarkNet's cryptographic security.

Leverage StarkNet's L2 scaling for sub-cent verification costs, enabling millions of micro-achievements without congesting Ethereum mainnet.

Get a production-ready verifier API and SDK in under 2 weeks. We handle the ZK-circuit complexity, you focus on game logic.

Unlock revenue from verifiable achievement NFTs, provably rare digital collectibles, and certified tournament outcomes for sponsors.

Receive verifiers built with Cairo 1.0, audited for security, and designed for easy upgrades to StarkNet's latest performance improvements.

We begin with a collaborative design session to define your verifier's logic, data inputs, and integration points. This phase establishes clear requirements, technical scope, and a fixed-price quote.

Our expert StarkNet engineers build your custom verifier logic in Cairo 1.0, implementing gas-optimized circuits and secure state management patterns for Starknet mainnet.

Before external audit, our senior auditors conduct a comprehensive review for logic flaws, arithmetic overflows, and Cairo-specific vulnerabilities using static analysis and manual testing.

We deploy the audited verifier to Starknet testnet, assist with frontend/backend integration, and conduct end-to-end testing with your application's workflow.

We manage the mainnet deployment, configure monitoring for proof generation success rates and gas costs, and provide 30 days of post-launch support.
