Real-World Results
Challenge: Uncompetitive Gas Fees on a High-Volume Lending Protocol
The client's core lending and borrowing functions were becoming prohibitively expensive for smaller users due to network congestion. Their primary challenge was to significantly reduce gas costs without compromising the protocol's security or decentralization.
Key Challenges:
- High gas consumption in the primary `borrow()` and `repay()` functions.
- Inefficient data storage for user loan information.
- Lack of batching capabilities for multiple operations.
- A potential reentrancy vulnerability in their rewards distribution contract.
Our AI-Augmented Solution
We deployed our full analysis and optimization suite. The AI immediately flagged inefficient storage access patterns and redundant calculations within loops. Our architects then designed a solution that combined AI-driven code changes with strategic architectural improvements.
Solution Highlights:
- Refactored data structures to pack multiple variables into single storage slots.
- Replaced external calls in loops with a single, aggregated data-fetching call.
- Introduced a batch transaction function allowing users to perform multiple actions in one transaction.
- Patched the reentrancy vulnerability by implementing the checks-effects-interactions pattern.
Challenge: Optimizing an ERC-721A Minting Contract for a High-Demand Launch
The client anticipated tens of thousands of users attempting to mint simultaneously. Their goal was to minimize the gas cost, especially for users minting multiple NFTs in a single transaction, and to ensure the contract was robust enough to handle the extreme load.
Key Challenges:
- The existing contract had gas costs that scaled linearly with the number of NFTs minted.
- Inefficient logic for whitelist verification.
- Risk of front-running bots exploiting the minting function.
- No protection against users minting more than their allocation.
Our AI-Augmented Solution
Our AI analysis confirmed that the minting loop was the primary gas bottleneck. We recommended migrating their logic to an ERC-721A standard, which is specifically designed for gas-efficient batch mints. Our AI also helped optimize their Merkle Tree verification for the whitelist.
Solution Highlights:
- Re-architected the contract based on the ERC-721A standard, resulting in nearly constant gas costs for batch mints.
- Optimized the Merkle proof verification process, reducing gas for whitelisted minters.
- Implemented anti-bot measures and strengthened access controls.
- Added robust checks to prevent users from exceeding their minting limits, even across multiple transactions.
Challenge: Ensuring Scalability and Cost-Effectiveness for an Enterprise Supply Chain Ledger
The client's platform needed to log thousands of updates daily as products moved through the supply chain. Their initial contract design was storing too much data on-chain, leading to blockchain bloat and escalating operational costs.
Key Challenges:
- Storing large data payloads (like shipping manifests) directly in contract storage.
- Complex, multi-step processes that required numerous separate transactions.
- Access control logic was overly complicated and gas-intensive.
- Lack of an efficient event logging system for off-chain applications.
Our AI-Augmented Solution
Our AI analysis pinpointed the excessive on-chain data storage as the critical issue. We designed a hybrid solution that stores only essential data hashes on-chain while leveraging IPFS for the larger data payloads. This drastically reduced storage costs and improved performance.
Solution Highlights:
- Implemented an event-based architecture, storing only cryptographic proofs on-chain and emitting detailed logs.
- Combined multiple state updates into a single, atomic transaction.
- Refactored the role-based access control to be more gas-efficient.
- Integrated with IPFS for decentralized, off-chain storage of large documents, linked by on-chain hashes.

Frequently Asked Questions
A standard manual audit relies solely on human experts to review code line-by-line. It's effective but can be slow and may miss non-obvious, complex interactions. Our AI-driven approach enhances this process by using machine learning models to analyze thousands of possible execution paths, simulate economic attacks, and identify gas-inefficient patterns at a scale no human team can match. Our human experts then validate and implement the AI's findings, giving you the best of both worlds: the breadth of AI and the depth of human expertise.
While it varies by project, we typically see clients achieve gas savings between 20% and 40%. For dApps with significant transaction volume, the cost of our service is often recouped in just a few months. We provide a detailed ROI projection as part of our initial analysis, so you can see the potential financial benefits before committing.
This is a critical concern, which is why our process is always human-led. The AI's role is to suggest optimizations and flag potential issues. Every single suggested change is then rigorously reviewed, tested, and validated by our senior blockchain engineers before it is recommended for implementation. We have a multi-stage testing process to ensure that any refactored code is more secure and efficient than the original, not less.
Our primary expertise is in Solidity for EVM-compatible chains, including Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, and Avalanche. We also have capabilities for analyzing contracts written in Vyper. While our AI models are most mature for the EVM, we are continuously expanding our support for other ecosystems like Solana (Rust) and Cosmos (Go). Please contact us to discuss your specific needs.
A typical engagement, from initial analysis to delivery of optimized code, takes between 1 to 3 weeks, depending on the complexity and size of your codebase. The initial AI analysis can often be completed within 48-72 hours, giving you rapid initial insights.
You will receive a comprehensive final report detailing our findings, the changes made, and the measured improvements. This includes a security vulnerability report, a gas optimization report with before-and-after metrics, and the fully refactored and commented source code, delivered as a pull request to your repository. You retain 100% ownership of all intellectual property.
