Secure, production-ready smart contracts built for your specific Web3 use case.
We architect and deploy custom Solidity smart contracts that form the immutable backbone of your application. Our development process ensures security, gas efficiency, and compliance with established standards like ERC-20, ERC-721, and ERC-1155.
Deploy a battle-tested, audited contract suite in as little as 2-4 weeks.
Our development lifecycle is built for security and speed:
OpenZeppelin libraries and best practices.Hardhat or Foundry.Our specialized audit methodology targets the unique vulnerabilities of recurring revenue models, ensuring your smart contracts are secure, compliant, and ready for production.
We meticulously analyze your subscription state machine, payment scheduling, and proration logic to prevent revenue leakage and ensure accurate, tamper-proof billing cycles.
Review of role-based permissions for admin functions, upgradeability, and user management to prevent unauthorized modifications to subscription plans or user status.
Security assessment of plan upgrades, downgrades, and cancellations to ensure smooth state transitions and protect against exploits during user lifecycle changes.
Verification of secure oracle usage for dynamic pricing, FX rates, or off-chain data, ensuring resistance to manipulation and downtime.
Detailed gas profiling for key user interactions (sign-up, renewal) to minimize transaction costs and ensure economic viability at scale.
Evaluation of contract design against relevant financial regulations, including refund policies, consumer protection, and audit trails for enterprise clients.
We deliver more than a checklist. Our subscription contract audits are engineered by specialists who understand the unique financial logic, upgrade paths, and attack vectors of recurring revenue models.
We analyze and optimize the gas cost of your most frequent operations (e.g., chargeSubscription), reducing user transaction fees by 15-40% and improving protocol economics.
We test the security of integrations with price oracles (Chainlink), payment processors, and off-chain services to prevent manipulation and ensure reliable subscription execution.
Deep validation of proration math, revenue distribution, fee calculations, and refund logic to prevent rounding errors and ensure precise, predictable cash flows.
Choose the right level of security coverage for your subscription protocol's development lifecycle, from initial launch to enterprise-grade production.

Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy custom Solidity/Rust smart contracts with enterprise-grade security and gas optimization. Our development lifecycle includes formal verification, comprehensive unit testing, and third-party audits from firms like CertiK and Quantstamp to ensure your core logic is bulletproof.
From token standards to complex DeFi primitives, we deliver battle-tested code that executes as intended.
ERC-20/ERC-721 extensions.OpenZeppelin standards and mitigation of common vulnerabilities (reentrancy, overflow).NatSpec comments, and verification on Etherscan or equivalent explorers.Answers to the most common technical and process questions from CTOs and engineering leads evaluating smart contract security audits for subscription models.
We employ a hybrid methodology combining automated analysis with deep manual review. Our process includes: 1) Static Analysis using Slither and custom tools to map all payment flows and state changes. 2) Manual Line-by-Line Review by two senior auditors focusing on business logic, access control, and upgrade paths. 3) Scenario Testing for edge cases like proration, failed payments, grace periods, and cancellation clawbacks. 4) Formal Verification for critical invariants (e.g., "total revenue always equals sum of user balances"). This multi-layered approach has secured over $500M+ in subscription protocol TVL.
