ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi & DAOs: Automated market makers, staking pools, governance modules.
- Security First: Multi-signature deployment, comprehensive unit testing, and third-party audit preparation.
- Delivery: Production-ready code delivered in 2-4 weeks, complete with documentation and deployment scripts.
Core Technical Capabilities
Our StarkNet ZK-Proof Achievement Verifier is engineered for enterprise-grade reliability and seamless integration, delivering cryptographic certainty for your on-chain credentials.
Cairo Smart Contract Development
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.
Zero-Knowledge Proof Integration
Seamlessly integrate STARK proofs generated off-chain. Our system handles proof verification, state updates, and event emission, ensuring data integrity with cryptographic guarantees.
Secure Oracle & Data Feeds
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.
Gas-Optimized Transaction Management
We implement batch verification and state compression techniques to minimize L1 settlement costs, providing predictable and reduced gas fees for your users.
Comprehensive Audit & Security
Every verifier undergoes rigorous security review, including manual code audits, formal verification where applicable, and testing against known vulnerability patterns.
Scalable Deployment & Monitoring
We provide automated deployment pipelines to StarkNet testnet/mainnet and set up monitoring dashboards for proof volume, verification success rates, and system health.
Business Outcomes for Your Game
Our StarkNet ZK-Proof Achievement Verifier delivers concrete improvements to your game's core metrics, from player engagement to operational efficiency.
Proven Player Retention
ZK-verified achievements create immutable, trustless proof of skill, increasing player investment and average session time by up to 40%.
Secure & Trustless On-Chain Economy
Eliminate fraud in tournaments and leaderboards. Our verifier ensures only legitimate achievements mint NFTs or trigger rewards, backed by StarkNet's cryptographic security.
Scalable Infrastructure for Mass Adoption
Leverage StarkNet's L2 scaling for sub-cent verification costs, enabling millions of micro-achievements without congesting Ethereum mainnet.
Seamless Developer Integration
Get a production-ready verifier API and SDK in under 2 weeks. We handle the ZK-circuit complexity, you focus on game logic.
New Monetization Streams
Unlock revenue from verifiable achievement NFTs, provably rare digital collectibles, and certified tournament outcomes for sponsors.
Audited & Future-Proof Code
Receive verifiers built with Cairo 1.0, audited for security, and designed for easy upgrades to StarkNet's latest performance improvements.

Our Development & Audit Process
A rigorous, multi-stage process designed to deliver secure, production-ready verifiers with predictable timelines and zero surprises.
Architecture & Specification
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.
Cairo 1.0 Development
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.
Internal Security Review
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.
Testnet Deployment & Integration
We deploy the audited verifier to Starknet testnet, assist with frontend/backend integration, and conduct end-to-end testing with your application's workflow.
Mainnet Launch & Monitoring
We manage the mainnet deployment, configure monitoring for proof generation success rates and gas costs, and provide 30 days of post-launch support.
Frequently Asked Questions
Get clear answers on our development process, security, and timelines for your custom StarkNet verifier.
A ZK-Proof Achievement Verifier is a smart contract system built on StarkNet that allows users to cryptographically prove they've completed specific on-chain or off-chain tasks without revealing the underlying data. It verifies zero-knowledge proofs submitted by users, minting soulbound tokens (SBTs) or updating a registry as verifiable credentials. We build custom verifiers for use cases like gaming achievements, KYC/AML attestations, educational credentials, and loyalty program milestones.
