Smart Contracts That Hold Up
When It Matters.
Audited, upgradeable, and production-hardened. We build smart contracts that investors, regulators, and users can trust - with a written security report on every deployment.
Audit pass rate on all Renesis-deployed contracts
Smart contracts deployed across 4 chains
Capital secured in Renesis-audited token contracts
Every Contract Type. Every Chain.
From a simple ERC-20 token to a complex multi-contract protocol with upgradeable governance. We build, test, and audit smart contracts that survive contact with real users and real money.
ERC-20 / BEP-20 / SPL Token Contracts
Standard and custom fungible token contracts for Ethereum, BNB Chain, and Solana. Includes transfer restrictions, minting controls, burn mechanics, and role-based access.
NFT Contracts (ERC-721 / ERC-1155)
Non-fungible and semi-fungible token contracts for collections, gaming, and loyalty programs. Includes royalty enforcement, reveal mechanics, whitelist minting, and batch operations.
DeFi Protocol Contracts
Staking pools, yield farming mechanics, liquidity pair contracts, vesting schedules, and lending protocol logic, built with economic attack resistance as a baseline requirement.
Upgradeable Proxy Contracts
UUPS and Transparent Proxy patterns for contracts that need to evolve post-deployment. Full upgrade governance including timelock controls and multi-sig approval requirements.
DAO & Governance Contracts
On-chain governance systems with proposal creation, voting mechanics, quorum controls, and treasury management. Compatible with Compound Governor and OpenZeppelin Governor.
Smart Contract Security Audits
Independent security review of existing contracts. Static analysis, manual review, economic attack modeling, and a written findings report with severity classifications.
How We Audit Smart Contracts
Security is not a checkbox. Our audit process is a structured, four-phase methodology that surfaces vulnerabilities a single tool pass will miss, and produces a written report your team, investors, and community can trust.
Automated Analysis
We run the contract through industry-standard static analysis tools: Slither, Mythril, and custom scripts targeting known vulnerability patterns in Solidity and Rust.
Manual Code Review
Senior Solidity engineers review the codebase line by line, focusing on logic errors, access control weaknesses, integer overflow risk, reentrancy patterns, and gas optimization.
Economic & Attack Modeling
We model the contract's economic behavior under adversarial conditions: flash loan attacks, front-running, sandwich attacks, governance manipulation, and liquidity drain scenarios.
Audit Report & Remediation
All findings are compiled into a written audit report with severity ratings, remediation recommendations, and a re-audit of any fixed issues. Final report is shareable with investors and community.
How findings are rated in every Renesis audit report
Exploitable vulnerability. Total fund loss risk. Fix required before deployment.
Significant risk of partial fund loss or protocol manipulation.
Degrades protocol safety or functionality under specific conditions.
Minor risk or best practice deviation. Fix recommended but not blocking.
Observation or optimization suggestion with no security impact.
Our Smart Contract Development Process
Requirements & Contract Specification
We begin with a detailed specification session. Every function the contract must perform is documented, every access control rule is defined, and every edge case is identified before development begins. Ambiguity at this stage becomes a bug at deployment. We eliminate it here.
Outcome: A complete contract specification document: functions, access roles, state variables, events, and edge case handling, agreed and signed off before development starts.
Architecture & Pattern Selection
We select the right contract patterns for your use case: standard ERC implementations, upgradeable proxies, multi-sig requirements, and governance hooks. The architecture is documented and reviewed before implementation so your team understands every structural decision before a line of code is written.
Outcome: A contract architecture document with selected patterns, inheritance structure, access control model, and upgrade strategy where applicable.
Development & Unit Testing
We build the contract to spec using Hardhat or Foundry, with a comprehensive unit test suite written in parallel. Every function is tested against expected behavior, boundary conditions, and failure modes. Test coverage targets 95% minimum on all critical contract logic before the code leaves the development environment.
Outcome: A fully developed contract with a unit test suite achieving 95%+ coverage on critical functions, documented and version-controlled.
Automated Security Scanning
The contract is run through static analysis tools including Slither and Mythril. Automated findings are triaged by severity, false positives are filtered, and genuine issues are queued for the manual review phase. This stage catches the category of vulnerability that pattern-matching tools reliably identify before human time is spent.
Outcome: An automated analysis report with findings triaged by severity and confirmed issues documented for manual review.
Manual Security Audit
Senior Solidity engineers conduct a line-by-line manual review of the contract, focusing on logic correctness, economic attack resistance, reentrancy patterns, access control integrity, and gas optimization. Attack scenarios are modeled explicitly, not assumed away. All findings are documented with reproducible proof of concept where applicable.
Outcome: A manual audit findings document with severity-rated issues, attack scenario documentation, and remediation recommendations for each finding.
Remediation & Re-Audit
All critical and high severity findings are fixed before deployment proceeds. The remediated code is re-audited to confirm each fix resolves the identified issue without introducing new vulnerabilities. A final written audit report is produced, covering original findings, applied fixes, and the re-audit outcome for each item.
Outcome: A final, signed audit report with all critical and high findings resolved, re-audited, and confirmed, ready for investor and community disclosure.
Deployment & Post-Deployment Monitoring
We handle the deployment process: mainnet configuration, constructor parameter validation, deployment script execution, and on-chain verification. Post-deployment monitoring covers transaction anomaly detection, contract interaction tracking, and an on-call engineering window covering the critical 72-hour post-launch period.
Outcome: Contract live on mainnet, verified on block explorer, monitored for 72 hours post-deployment with anomaly alerts active.

Frequently Asked Questions
Common questions about smart contract development and auditing. Can't find the answer you need?
Have a specific question?
Talk to our Blockchain teamYes. We provide standalone smart contract audits for contracts built by other development teams. The audit scope, timeline, and deliverables are the same regardless of who wrote the code. Standalone audits typically take 1 to 3 weeks depending on contract complexity.
Ethereum, BNB Chain, Polygon, and Solana are our primary supported chains. We also work with EVM-compatible L2 networks including Arbitrum and Base on a project basis. Chain selection is part of our discovery process. We recommend based on your use case.
Automated tools catch known vulnerability patterns quickly but miss logic errors and economic attack vectors. Manual audit by experienced engineers catches what automation cannot. Our process combines both - automated scanning followed by manual review and economic modeling.
A standard token contract audit takes 5 to 10 business days. Complex DeFi protocols with multiple interacting contracts typically take 2 to 4 weeks. Timeline is confirmed during the scoping call after we review the codebase.
The audit report includes: executive summary, methodology description, all findings with severity ratings, proof-of-concept details for critical issues, remediation recommendations, and a re-audit confirmation section once fixes are applied. It is formatted for public disclosure.
