Why Blockchain Game Security Goes Beyond Smart Contracts
When it comes to developing blockchain games, smart contract audits are just one piece of the puzzle. At Cyrex, we’ve been securing blockchain and Web3 games for years—and we’re seeing a critical gap in how studios are approaching game security. This blog explains why in-game security matters just as much as your smart contracts and how to protect your blockchain game from every angle.
We’ve covered this before in our blockchain security webinar, explained the importance of Web3 game penetration testing, and broke down smart contract security essentials. But today, let’s go deeper.
Blockchain Gaming Security Isn’t Just About Smart Contracts
There’s growing awareness of the importance of securing blockchain elements like smart contracts. That’s great news. But too often, the same level of rigour isn’t being applied to the game systems themselves.
We frequently see projects where the smart contract is airtight—audited, stress-tested, and monitored—yet the actual game logic, reward mechanics, or user interactions are left exposed. This creates a dangerous gap where players can exploit game logic to illegitimately obtain rewards, items, or even NFTs—completely bypassing your smart contract protections.
Real Risks: What Happens If In-Game Systems Are Exploitable?
Imagine your game has a rare item that can be earned through a challenging quest. That item is then minted as an NFT, making it a prized and limited digital asset. But a bug in the reward logic allows players to repeat the quest indefinitely. Suddenly, that rare NFT floods the market. The item is devalued. Your community is frustrated. Your game's credibility takes a hit.
And that’s just one example. Other common exploits include:
- Item duplication bugs leading to NFT inflation
- Account hijacking through vulnerable APIs or logic
- Speed or wall hacks that undermine gameplay
No matter how secure your smart contracts are, if your in-game systems can be exploited, your blockchain economy is at risk.
Web3 Game Security Needs Full Coverage
The Web3 gaming space is still new, and many studios are either startups or transitioning from non-gaming industries. That’s why we stress this point: Smart contract security is essential—but it’s not enough.
At Cyrex, our goal is comprehensive protection. We offer full-stack security for blockchain games—from Web3 component audits to in-game penetration testing and load testing.
Whether it’s gameplay loops, reward systems, asset minting, or player physics, every component must be secure. Our cross-domain expertise lets us secure the bridge between traditional gaming infrastructure and decentralised tech.
Case Studies: Blockchain Games We’ve Secured
We’ve worked with some of the most innovative Web3 game studios, including:
- Immutable – pioneers in blockchain gaming infrastructure
- NYAN Heroes – built on Solana, combining NFTs with shooter gameplay
- Mythical Games – creators of Blankos Block Party
FAQ: Blockchain Game Security Questions
How does Cyrex secure more than just smart contracts?
We go beyond smart contract auditing by testing your entire game system. We simulate gameplay scenarios, test for economy abuse, assess reward logic, and evaluate real-world player interactions to identify vulnerabilities. Our combined approach uses code review, scenario-based testing, and game engine analysis.
What are examples of non-smart contract vulnerabilities?
We’ve uncovered reward duplication glitches, account takeovers via session hijacking, and even physics manipulation exploits that let players break boundaries or teleport. These are all in-game issues—not blockchain ones—but they compromise the entire player experience.
What makes Cyrex different from other Web3 security companies?
Our strength lies in our dual expertise. We’re game security experts first, with deep roots in the gaming industry, and we’ve evolved with blockchain. That allows us to deliver true 360° coverage—protecting both the on-chain and in-game dimensions of your title.
