Create a Testnet sandbox across various blockchain networks, complete with an integrated faucet and explorer.
Overview
With the Buildbear Extension , you can effortlessly create BuildBear sandboxes from various blockchain networks, customized for DApp development and testing.
Benefits of creating your Sandbox with BuildBear
BuildBear Faucet: Instantly access native and popular ERC20 Testnet tokens through the BuildBear Faucet, eliminating the need for manual token accumulation and saving valuable time.
Mainnet State: The BuildBear Sandbox facilitates the forking of Mainnets and rapid Sandbox, streamlining testing alongside Mainnet protocols and eliminating the necessity for mock environments.
Transaction Speed: Experience transaction processing that’s 4 timesfaster than public testnets. This dramatic reduction in contract test script runtime speeds up iterations.
Advanced Testing: The BuildBear Sandbox empowers you to manipulate time, capture snapshots, adjust Chainlink token prices, and impersonate other accounts for testing abnormal scenarios. These capabilities aren’t possible on public testnets.
Instructions
Follow these steps:
Select the blockchain from which you wish to create the Sandbox.
If the blockchain offers a Testnet, choose between Testnet and Mainnet. After selecting the chain.
Click on "Create." Within a few seconds, your Sandbox will be up and running.
Adding the RPC to the hardhat.config.js, copy the RPC, and insert it in the hardhat.config.js under "Networks.”
Click on "Go to Faucet". You'll be redirected to your Sandbox Faucet, you can mint Native Tokens and ERC20 Tokens from the Faucet to your wallet. Then, click on "Add Network" to Add your Sandbox Network to the MetaMask wallet.
To view your Transactions, click on "Go to Explorer." You'll be redirected to your Sandbox Explorer, you can view all your transactions and interact with the deployed contracts directly from Explorer.
