Overcoming Development Challenges with BuildBear

Prof. Fábio Santos is a Web3 developer and YouTube Educator known for breaking down complex technical topics like Blockchain, Artificial Intelligence, IoT, Programming, and even Astronomy. He has produced numerous tutorials for developers, including a popular video titled “How to use BuildBear to test Smart Contracts and DAPPs.”

With a passion for teaching and a technical toolkit spanning multiple domains, Prof. Fábio is committed to equipping the next generation of builders with the right tools and knowledge.

• Explorer Limitations: The lack of an explorer on local Hardhat nodes made it difficult to visualize transitions and debug failed transactions.
• Impersonation Blockers: Public testnets restrict account impersonation, limiting testing possibilities and blocking advanced workflows.
• Testnet Delays: Public testnets, like Sepolia, often introduced transaction delays of up to 13.5 seconds, slowing down iteration cycles.
• Token Scarcity: Acquiring enough testnet tokens for complete simulations was a time-consuming and often frustrating process.

BuildBear gave Prof. Fábio a significant productivity boost, allowing him to:

• Speed up testing: Reduce the time taken to complete test scripts with lightning-fast transactions.
• Debug effectively: Visualize and trace transactions via a rich explorer interface.
• Use Testnet tokens instantly: Thanks to the integrated faucet, he had native and ERC-20 tokens at his fingertips.
• Impersonate any wallet: BuildBear’s impersonation feature allowed full flexibility during development.
• Fork Mainnets: Simulate real-world behavior by forking chains like Ethereum, Polygon, Arbitrum, and more with a click.

BuildBear seamlessly integrated into Prof. Fábio’s development workflow and content creation process. He was able to produce educational material that not only explained the concepts clearly but also demonstrated practical development on real-world dApps, without friction or delay.
