How Irtisam Abdur Rab Optimised a Uniswap Yield Aggregator Using BuildBear

Irtisam Abdur Rab is a Senior Developer at Genesis IT Labs and a blockchain lead based in Pakistan.
While building a Uniswap Yield Aggregator, he needed a seamless way to test how the smart contract would mint, hold, and rebalance Uniswap v3 NFT positions.

But his existing tools weren’t cutting it:

• Anvil and Forge forks lacked USDC faucets, making it impossible to simulate real swaps.
• No working explorer meant debugging contract interactions was slow and painful.
• Contract size limitations made testing full versions of the app locally nearly impossible.
• Persistent state was out of reach, which broke the feedback loop during iteration.

The aggregator contract needed to custody Uniswap LP NFTs, programmatically rebalance positions, and charge small fees, all of which demanded a better testing environment.

Irtisam found BuildBear through a StackOverflow thread and instantly saw the potential to unblock his development process:

• Token faucet support for any token, including USDC, made swap simulations and liquidity provisioning possible.
• No contract size limits, allowing him to test production-level smart contracts without compromise.
• A full-featured explorer made it easy to debug NFT custody and rebalance flows.
• The ability to persist and replay state streamlined rebalancing logic and test scenarios.

With BuildBear, Irtisam could run realistic simulations and iterate faster, without hacking around infrastructure issues.

With BuildBear, the Uniswap Yield Aggregator could finally be tested in a real-world-like sandbox:

• Saved hours every week by eliminating local testnet crashes and faucet issues
• Rebalanced NFT positions reliably and validated fee mechanics under real conditions
• Achieved production-ready testing without compromising on complexity or contract size

BuildBear gave Irtisam full control, confidence, and visibility across the entire development lifecycle.

BuildBear enabled Irtisam to break through the bottlenecks of local testing and build a sophisticated DeFi product with real confidence.

For developers working on complex smart contract systems, BuildBear offers:

• A no-limit, faucet-rich sandbox for any token and dApp
• Persistent state that supports iterative development
• Deep visibility through a powerful blockchain explorer

For Irtisam, it wasn’t just about making it work, it was about making it reliable, repeatable, and fast.
