How Lef Giak Overcame DApp Development Challenges Using BuildBear

Lef Giak, a web3 DApp developer, has been building DApps since 2019. Recently, he started contributing to web3 auditing through Code4rena contests.

As he built and tested new contracts, several blockers emerged:

• Token Scarcity: Acquiring enough Testnet tokens for thorough testing took too much time.
• Transaction Confirmation Delays: Public Testnets like Sepolia often delayed transactions for up to 13.5 seconds, especially frustrating when testing and iterating rapidly.
• Mainnet Testing Hassles: Setting up complex protocol environments that mimicked Mainnet behavior was time-consuming and error-prone.

These pain points limited how fast and effectively he could build.

Lef Giak integrated BuildBear into his development workflow and became a premium user to unlock its full potential.

• Mainnet Forking: He used BuildBear’s ability to fork Mainnet and spin up test environments instantly, no mock setups required.
• Faucet Access: Native and popular ERC20 tokens were always available via BuildBear’s faucet, eliminating token shortages.
• Explorer and Tracer: BuildBear’s explorer made debugging fast and visual, thanks to built-in tracing.
• Instant Confirmations: Test scripts involving 10 transactions completed in under 26 seconds, what took 2+ minutes on public testnets.

It was the all-in-one dev stack Lef needed to accelerate his testing loop.

With BuildBear:

• Testnet token access became seamless
• Transaction speed increased dramatically
• Mainnet-based testing was easier and more reliable

The dev process became faster, less error-prone, and much more enjoyable.

For independent developers like Lef Giak, BuildBear isn’t just a sandbox, it’s infrastructure that simplifies everything.

• Fork mainnet in seconds
• Test with real tokens and real flows
• Cut down development time with instant feedback and full visibility

BuildBear gave Lef the tools to test like an enterprise team, solo.
