Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy audit-ready smart contracts on EVM and Solana networks. Our development process ensures gas optimization, upgradeability patterns, and comprehensive test coverage from day one.
Deliver a secure, functional MVP in as little as 2-3 weeks.
ERC-20, ERC-721, ERC-1155, staking, vesting, governance, and custom DeFi primitives.OpenZeppelin standards, formal verification, and pre-audit internal reviews.Our modular system is built for financial institutions requiring institutional-grade security, real-time verification, and seamless integration with existing risk management frameworks.
Cairo-based ZK circuits that generate cryptographic proofs of collateral sufficiency without exposing sensitive on-chain positions. Enables privacy-preserving compliance checks for DeFi lending and derivatives.
Aggregates real-time collateral data from Ethereum, Arbitrum, and Optimism with fraud-proof mechanisms. Delivers verifiable price feeds and position data directly to the StarkNet sequencer.
On-chain verifier contract that validates ZK proofs and updates the canonical collateral registry on L1. Provides a single source of truth for all verified positions with immutable audit trails.
Granular dashboard and API for setting loan-to-value ratios, liquidation thresholds, and asset whitelists. Supports dynamic risk models that adjust based on market volatility.
Automated generation of proof-of-reserves and capital adequacy reports for regulators. Exports verifiable attestations compatible with accounting and audit systems.
Our StarkNet ZK-Rollup collateral verification service delivers measurable improvements in security, efficiency, and compliance, directly impacting your bottom line.
Verify RWA collateral (real estate, invoices, commodities) on-chain in under 5 seconds. Eliminate manual checks and reduce operational overhead by 70%.
Immutable, timestamped proof of ownership and valuation on StarkNet. Pass audits with a transparent, on-chain history for every asset, simplifying KYC/AML processes.
Batch thousands of verifications into a single ZK-proof, slashing L1 gas fees by over 95%. Enable micro-transactions and new business models for tokenized assets.
Deploy a production-ready verification system in 4-6 weeks using our modular Cairo smart contracts and pre-built oracle connectors.
Handle millions of verifications daily with sub-second finality. Our managed node infrastructure guarantees 99.9% uptime with automated failover.

A rigorous, multi-layered approach designed to deliver secure, scalable, and production-ready StarkNet applications. We focus on verifiable outcomes, not just features.
Every line of Cairo smart contract code undergoes formal verification using tools like Cairo Verifier and manual security audits. We ensure mathematical proof of correctness for your core collateral logic.
We design your ZK-Rollup's state model and transaction flow from the ground up for minimal L1 settlement costs. This includes strategic storage layout and batch processing patterns.
Comprehensive test suites simulate real-world scenarios, including oracle failures, extreme volatility, and bridge delays, ensuring your verification system is resilient under stress.
We manage the deployment to StarkNet mainnet and testnet, setting up real-time dashboards for TVL tracking, proof generation latency, and RPC endpoint health.
A technical breakdown of how StarkNet ZK-Rollup verification fundamentally transforms capital efficiency and operational security compared to legacy systems.
| Comparison Factor | Traditional On-Chain Collateral | Chainscore ZK-Rollup Verification |
|---|---|---|
Capital Efficiency | 100% collateral locked on-chain | Up to 90% capital reduction via ZK proofs |
Settlement Finality | ~15 minutes (Ethereum L1) | < 2 seconds (StarkNet L2) |
Transaction Cost | $5-$50 per verification | < $0.01 per verification |
Security Model | Direct on-chain exposure, high attack surface | Cryptographic validity proofs, inherited L1 security |
Audit & Compliance Overhead | Manual, periodic, high-cost | Continuous, automated, programmable |
Operational Complexity | High (oracle management, multi-sig ops) | Low (smart contract automation, verifier-driven) |
Time to Integrate New Asset | Weeks (new audits, deployments) | Days (standardized proof circuits) |
Typical Implementation Timeline | 3-6 months | 4-8 weeks |

A standard deployment takes 2-4 weeks from kickoff to mainnet. This includes requirements analysis, custom circuit design, smart contract development, and a full security audit. Complex multi-asset systems or novel verification logic can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial consultation.
