Nyan Heroes

NYAN Heroes is a AAA third-person shooter built on the Solana blockchain, combining battle royale gameplay with NFT ownership and tokenized rewards. Players pilot Guardian Mechs, explore biomes, and earn $CTNP tokens through in-game activity.

Ahead of NFT pre-sales and marketplace activity, the platform faced two critical risks:

• Smart contract and staking infrastructure vulnerabilities that could impact NFT integrity and token flows.
• Scalability under heavy traffic, particularly during limited NFT pack drops where demand spikes are expected.

Web3 launches, especially NFT drops, introduce concurrency pressure and transactional risk simultaneously. A weakness in contract logic or marketplace infrastructure during a high-traffic event can compromise both performance and user trust.

NYAN Heroes required validation across staking systems, NFT drop mechanics, and marketplace scalability before public release.

Cyrex supported the NYAN Heroes team across both security and scalability domains.

Our engagement included work on:

• Staking platform architecture
• NFT pack drop mechanics
• Associated smart contract infrastructure

We evaluated contract logic and interaction flows to ensure that NFT distribution and staking mechanisms were implemented securely and aligned with expected user behavior.

Given the high visibility of NFT pre-sales, validating smart contract reliability was essential to maintaining ecosystem integrity.

In parallel, Cyrex conducted structured load testing on the marketplace infrastructure.

The objective was to:

• Simulate high-traffic conditions during NFT pack drops
• Identify bottlenecks in transaction flows
• Validate system stability under concurrency spikes
• Ensure scalable performance during limited release events

By stress-testing the platform ahead of launch, the team gained insight into how the infrastructure would behave during peak activity windows.
