Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFT platforms. Our development process ensures gas optimization, upgradeability, and comprehensive security from day one.
ERC-20, ERC-721, ERC-1155, and ERC-4626 vaults.OpenZeppelin libraries and undergo internal review before third-party audit.Reduce your time-to-market with battle-tested Solidity patterns and a 2-week MVP delivery guarantee for standard implementations.
We provide full technical ownership and documentation, enabling your team to maintain and iterate. Our contracts are designed for mainnet deployment with confidence, backed by our experience across Ethereum, Polygon, and other EVM chains.
Our framework delivers deterministic, production-like environments to validate protocol upgrades with confidence, reducing deployment risk and accelerating your roadmap.
Our Upgrade Simulation & Testing Framework delivers concrete, quantifiable improvements to your development lifecycle, directly impacting your bottom line and security posture.
Identify and resolve upgrade risks in hours, not weeks. Our automated simulation suite replicates mainnet conditions to validate changes before deployment, eliminating costly trial-and-error cycles.
Deliverable: Production-ready upgrade packages in 2-4 weeks, not months.
Simulate every possible state transition and edge case before deployment. We catch logic errors, storage collisions, and gas limit issues that unit tests miss, preventing exploits and failed upgrades that can cost millions.
Deliverable: A comprehensive pre-deployment risk report with actionable fixes.
Replace manual, ad-hoc testing with a standardized, automated framework. Our reusable test suites and CI/CD integrations free your senior developers from repetitive validation work, allowing them to focus on core protocol innovation.
Deliverable: A turnkey testing pipeline integrated into your existing workflow.
Leverage battle-tested simulation patterns from securing over $500M in TVL. Our framework includes invariant testing, fork testing from live block numbers, and compliance checks against OpenZeppelin upgrade best practices.
Deliverable: Security audit-ready upgrade packages with documented proof of correctness.

We transform the high-risk, manual process of blockchain upgrades into a deterministic, automated workflow. Our framework ensures every upgrade is production-ready before it reaches mainnet, eliminating costly downtime and security vulnerabilities.
We map your current smart contract system and simulate the upgrade's impact on all dependencies, storage layouts, and user flows. This identifies breaking changes and gas cost implications before a single line of code is written.
Our engine auto-generates a comprehensive, upgrade-specific test suite covering edge cases, state transitions, and integration points. This replaces ad-hoc testing with systematic, reproducible validation.
We deploy the upgrade candidate to a forked replica of your production environment (Mainnet, Arbitrum, Polygon, etc.). This allows for real-world interaction testing with live state data without any risk.
We simulate the entire governance and execution process—from proposal to timelock to final execution—on a testnet. This validates all administrative pathways and prevents last-minute deployment failures.
We deliver a final verification report and a pre-audited, one-click rollback script. This guarantees you can deploy with confidence and have a proven escape hatch if unforeseen issues arise post-upgrade.

Get clear answers on how our framework ensures your protocol upgrades are secure, compliant, and ready for mainnet.
Our framework creates a forked replica of your production environment on a private testnet. We execute the proposed upgrade, simulate real-world user interactions and edge cases, and analyze the results. The process includes state migration validation, gas usage profiling, and automated security regression testing to identify issues before they reach mainnet.
