Since 2019, we've been the team that blockchain companies turn to when security and reliability matter most. Our story began with a simple belief — that thorough testing shouldn't be an afterthought.
From a small testing consultancy to Taiwan's trusted blockchain security partner
Started as a two-person team focusing on smart contract auditing. We noticed too many projects launching with basic security flaws that could've been caught early. Our first client was a local DeFi project — we found twelve critical vulnerabilities before their mainnet launch.
Added automated testing frameworks and began working with international blockchain projects. This year taught us that manual testing alone wasn't scalable. We developed our first proprietary testing tools that could catch edge cases human reviewers might miss.
Brought on specialists in cryptography and distributed systems testing. Our client base grew to include major exchanges and layer-2 solutions. We learned that different blockchain ecosystems require completely different testing approaches — what works for Ethereum doesn't work for Solana.
Became the go-to testing partner for blockchain startups across Asia-Pacific region. We've now tested over 200 smart contracts and helped prevent millions in potential losses. Each project teaches us something new about emerging attack vectors.
Focusing on cross-chain testing methodologies and zero-knowledge proof verification. The blockchain space keeps evolving, and so do the testing challenges. Our goal remains the same — catch problems before they become expensive disasters.
These principles guide every test we write and every vulnerability we investigate
We dig deeper than surface-level testing. Every function call, every state transition, every possible input combination gets examined. It's not uncommon for us to spend days on a single smart contract function that looks simple but has complex implications.
Academic security is different from practical security. We test how attackers actually behave — not how textbooks say they should. This means considering economic incentives, user behavior patterns, and the messy realities of production environments.
Technical findings mean nothing if developers can't act on them. We explain vulnerabilities in terms of business impact, provide concrete examples, and suggest specific fixes rather than vague recommendations.
Each new exploit we see in the wild becomes part of our testing methodology. We maintain detailed databases of attack patterns, vulnerable code structures, and defensive strategies that actually work in practice.
The expertise behind our testing methodologies comes from deep experience in both blockchain development and security research.
Lead Testing Architect
Astrid's background combines six years of smart contract development with formal security research. Before joining FlashLightWave, she worked at a major cryptocurrency exchange where she built their internal audit tools. She's the one who designed our methodology for testing complex DeFi protocols and cross-chain bridges.
What sets Astrid apart is her ability to think like both a developer and an attacker. She's discovered several novel attack vectors that are now part of standard security checklists across the industry.
The blockchain space moves fast, but security can't be rushed. We're building testing methodologies for technologies that don't exist yet — layer-3 solutions, quantum-resistant protocols, and fully decentralized autonomous systems. Our job is to stay ahead of both innovation and the threats that come with it.
