While originally created for the Ethereum blockchain, the Filecoin Ethereum Virtual Machine runtime (FEVM) allows Hardhat to be used to develop and deploy smart contracts on the Filecoin network.
The is a starter hardhat project for developing, deploying, and testing Solidity smart contracts on the Filecoin network. It functions in the same way as other Hardhat development kits. Check out the quickstart below to test it out!
This guide assumes you have the following installed:
A Filecoin address stored in
First, we need to grab the starter kit and install the dependencies.
Clone the Hardhat starter kit and move into the new fevm-hardhat-kit directory:
Use Yarn to install the project’s dependencies:
Add your private key to the .env file:
Get the addresses associated with the private key from Hardhat:
Now that we’ve got the kit set up, we can start using it to develop and deploy our contracts.
There are two main types of contracts:
Basic Solidity examples: Simple contracts to show off basic Solidity.
Filecoin API Examples: Contracts that demo how to use the Filecoin APIs in Solidity to access storage deals and other Filecoin-specific functions.
Make sure that your account has funds. You won’t be able to deploy any contracts without FIL or tFIL.
Run hardhat deploy to deploy all the contracts. This can take a few minutes:
Interact with the contracts using the available functions within the tasks folder. For example, you can get the balance of the simple-coin contract by calling the get-balance function:
