Xave's Internal Playground: BuildBear

Xave Protocol is on a mission to redefine capital mobility through real-world assets (RWAs), but testing the architecture behind this vision wasn’t simple. Building a system that moves tokenized RWAs seamlessly across multiple chains required a precise, secure, and reproducible testing setup.

Public testnets introduced unnecessary latency and uncertainty. Xave needed a deterministic environment where they could simulate multi-chain scenarios, test bridging logic, and validate smart contract behavior under complex configurations, without worrying about inconsistent RPCs or public network instability.

BuildBear Labs delivered a tailored solution that allowed Xave to test everything from core protocol logic to cross-chain interactions within isolated private sandboxes.

The team utilized BuildBear’s programmatic balance setting, impersonation of EOAs, and native faucet tools to create testing scenarios that mirrored real-world usage. The inclusion of the Blockscout explorer plugin provided a visual debugging layer, allowing the team to trace asset flows, validate bridge logic, and inspect contract calls with ease.

With BuildBear’s support for forking mainnets and customizing runtime environments, Xave engineers were able to create testnets that accurately reflected their deployment targets. They could easily simulate edge cases, debug events, and replay complex transactions.

With BuildBear, Xave accelerated their development lifecycle while reducing risk. The deterministic nature of their private sandboxes allowed for rigorous QA and deep testing of cross-chain features, ensuring reliability at every stage of development.

Xave launched confidently, backed by smart contracts that had been extensively stress-tested. They were able to debug faster, deploy safer, and innovate without fear of the unknown.

BuildBear Sandboxes gave Xave Protocol the edge they needed to launch a secure, efficient RWA infrastructure across chains. By removing public testnet noise and introducing powerful debugging tools, BuildBear helped Xave focus on what matters: shipping high-impact DeFi applications that unlock real-world liquidity in a trustless and scalable way.

For teams building in the RWA or multichain space, Xave’s journey with BuildBear is proof that better testnets create better products.
