Discover How Aaron Integrated testing Using BuildBear SandBox

Aaron is a Solidity developer with 2–5 years of Web3 experience. He’s currently building Timber, a DeFi protocol that leverages BTC to earn yield on EVM chains like Ethereum and Arbitrum.

When working on Timber, Aaron and his team faced several challenges:

Mainnet Forking: Testing their full-stack application required multiple tools and complex setup due to integration with existing Ethereum mainnet protocols. Creating and syncing the Mainnet state was time-consuming.

"Early in our project development, we needed a dependable method to fork the Ethereum mainnet for realistic contract testing without the risks and costs of actual deployments. Since our project integrates with existing DeFi protocols, setting up the Mainnet State, and integrating with UI and APIs was challenging." – Aaron

Privacy & Collaboration: Testing in a private environment and sharing real-time progress with the team was essential before shipping to mainnet. Version deployments also needed to be seamless and reviewable by the team.

Token Scarcity for Testing: Securing sufficient testnet tokens, both ERC-20 and native, was tedious and slow, making testing bandwidth-heavy interactions especially difficult.

Aaron and his team brought BuildBear into their workflow to solve these pain points.

"In a previous project, we ran a testnet where users could get tokens from a faucet and interact with the app. It worked, but doing that with BuildBear would have been much more powerful."

Full-stack Integration: BuildBear made it seamless to test smart contracts integrated with frontend components and APIs, enabling full-stack validation.

Staging Environment: The secure and collaborative staging environment allowed Aaron's team to validate new features together and share the entire application with stakeholders, including partners and investors.

Mainnet Forking: With BuildBear, spinning up mainnet-forked environments became a matter of seconds. This streamlined development and made testing with real-world protocol states effortless.

Unlimited Testing Resources: BuildBear’s faucet offered unlimited native and ERC-20 test tokens. Combined with the integrated explorer, it provided deep visibility and debugging power throughout the testing lifecycle.

Aaron’s experience highlights how BuildBear simplifies full-stack DApp testing in realistic conditions. For Timber and similar DeFi protocols, it's not just about testing contracts, it’s about making end-to-end development seamless, efficient, and shareable.
