We Find What Others Miss in Your Blockchain Code
Smart contracts hold millions in value. One overlooked vulnerability can drain everything. Our security audits catch critical flaws before they become expensive mistakes.
Get Your Audit Started
Security Issues We Actually Solve
After three years of finding critical bugs in DeFi protocols, we know exactly where smart contracts break. Here's what keeps us busy.
Reentrancy Attacks
The classic drain-your-funds bug that caught The DAO. We've seen dozens of variations and know how to spot them in complex contract interactions. Last month we found one that would have cost a client $2.3 million.
Access Control Failures
When your admin functions aren't properly protected, anyone can become the owner. We check every privilege escalation path and make sure your governance actually works as intended.
Oracle Manipulation
Price feeds can lie, and attackers know it. We test how your contracts handle bad data and build defenses against flash loan attacks that manipulate market prices.
Gas Optimization Issues
Expensive transactions kill user adoption. We find the loops that eat gas, the storage patterns that waste money, and the calculations that can be done cheaper.
How We Actually Audit Your Code
Step 1
Code Architecture Review
We start by understanding what your contract is supposed to do. Business logic, user flows, edge cases. Most bugs hide in the gap between intention and implementation.
Step 2
Automated Vulnerability Scanning
Our tools check for known patterns — the common mistakes that appear in 80% of contracts. This catches the obvious stuff so we can focus on the tricky problems.
Step 3
Manual Security Analysis
The real work happens here. We trace through every function, test edge cases, and think like attackers. This is where we find the bugs that matter.
Step 4
Exploit Development
Finding a bug isn't enough — we prove it works. We write actual exploit code that demonstrates the attack, so you understand exactly what would happen.
Real Vulnerabilities We've Caught
These aren't theoretical problems. Every bug we list here came from actual client audits in 2024 and early 2025.
A DeFi lending protocol had a rounding error that let borrowers withdraw more collateral than they deposited. The math looked right in testing, but edge cases with tiny amounts broke everything.
An NFT marketplace allowed sellers to cancel sales after buyers paid, keeping both the NFT and the money. The race condition was subtle but totally exploitable.

Why Our Audits Actually Matter
We started SparkFlowLite because too many security audits just check boxes. Clients get thick reports full of minor issues while missing the bugs that actually matter.
Our approach is different. We focus on the attacks that would actually happen — the ones that drain funds, break governance, or kill your protocol. We've seen what real exploits look like, and that experience guides everything we do.
Based in Ho Chi Minh City, we work with projects across Asia and globally. Time zones matter less than finding the bugs that could destroy your project.
Your Smart Contract Needs an Audit
Don't launch with unknown vulnerabilities. Get a thorough security review that finds real problems and gives you confidence in your code.
