Forks
Start using Tenderly Forks, lightweight simulated networks that you can use for development, testing, and other purposes.
Tenderly Forks are a lightweight blockchain replica where you can run transaction simulations. You can base your Fork on one of Tenderly's supported networks and any of the blocks in a specific network's history. All transactions you simulate through Forks are recorded in an isolated timeline, and available in Tenderly Debugger.
Each time you create a Tenderly Fork, you get 10 accounts, each with a balance of 100 test tokens.
You can use Forks through:
- The Fork JSON RPC that allows you to use Forks as a lightweight blockchain provider. This way, you can:
- Integrate the RPC into a Hardhat project by using it as a network URL in hardhat.config. You can use that network to test your deployment scripts and/or run smart contract tests. Explore this example hardhat project for details.
All transactions you send to fork will be visible in the Dashboard, and you can view them using the Debugger.

Additionally, you can do various custom actions on a Fork:
