# Getting Started with BuildBear

**[Developer DAO](https://daily.dev/sources/developerdao)** · 22 min read · 0 upvotes · 0 comments

## Summary

BuildBear is a platform for DApp development that provides private testnet sandboxes for EVM-compatible blockchains. The tutorial walks through creating a cross-chain bridge between Ethereum and Polygon sandboxes, implementing token swaps using Chainlink price feeds, deploying contracts with Foundry, verifying them with Sourcify, and building a Node.js relayer to handle cross-chain asset transfers. The guide covers sandbox setup, smart contract development, faucet usage, transaction debugging with Sentio, and end-to-end testing of bridging WETH and USDT tokens between chains.
