2. Search for "BuildBear".

3. Click "Install" on the BuildBear Extension.

Step 2: Create your BuildBear Sandbox

• Choose your preferred blockchain network.

Step 3: Explore Sandbox Options

• RPC: Use the Sandbox RPC for connecting your sandbox to development tools like Foundry and Hardhat.

• Go to Faucet: Access your sandbox's faucet to mint Native and ERC20 tokens.

• Go to Explorer: View and interact with transactions, deployed contracts, and debug with the transaction tracer.

Deploying and Verifying Contracts

Through Hardhat

• Add BuildBear to your network in the hardhat.config.js or hardhat.config.ts file.

networks: {
  buildbear: {
    url: "<https://rpc.buildbear.io/Sandbox_ID>",
  }
}

• Add a Custom Chain to the Etherscan Object for seamless integration.

etherscan: {
    apiKey: {
        buildbear: "verifyContrats"
    }
  customChains: [
    {
      network: "buildbear",
      chainId: CHAIN_ID,
      urls: {
        apiURL:"<https://rpc.buildbear.io/verify/etherscan/Sandbox_ID>",
        browserURL: "<https://explorer.buildbear.io/node/Sandbox_ID>",
      },
    },
  ],
}

Through Foundry

• Update your Foundry.toml file to include BuildBear's RPC endpoints and Etherscan configurations.

[rpc_endpoints]
buildbear = "<https://rpc.buildbear.io/Sandbox_ID>"
[etherscan]
buildbear = { key = "verifyContract", url="<https://rpc.buildbear.io/verify/etherscan/Sandbox_ID>" }

• Deploy contracts using simple command-line instructions.

forge script script/<SCRIPT_NAME>.s.sol --rpc-url buildbear --private-key "<PRIVATE_KEY>" --broadcast --slow

To verify the deployed contracts, execute the following command:

forge verify-contract --constructor-args "" --etherscan-api-key "verifyContract" --verifier-url "<https://rpc.buildbear.io/verify/etherscan/gradual-blade-6d2a5b2a>" <DEPLOYED_CONTRACT_ADDRESS> <PATH>/<CONTRACT_NAME>.sol:<CONTRACT_NAME>
