StarkNet Development Environment Setup

This README provides instructions for setting up a local development environment for StarkNet using the StarkNet Devnet and Protostar tools.

Prerequisites

Before proceeding, ensure you have Docker installed on your system.

Running StarkNet Devnet

Start the StarkNet Devnet using Docker with the following command:

docker run -p 5050:5050 shardlabs/starknet-devnet-rs --seed 0

This command runs the StarkNet Devnet on port 5050 and initializes it with a seed value of 0.

Deploying Contracts with Protostar

To deploy contracts using Protostar, follow these steps:

1. Build the Contract:

   Build your contract using the protostar build-cairo0 command:

   protostar build-cairo0

   This command compiles your Cairo contracts and prepares them for deployment.

2. Set Environment Variable:

   Set the PROTOSTAR_ACCOUNT_PRIVATE_KEY environment variable to your private key:

   export PROTOSTAR_ACCOUNT_PRIVATE_KEY=0x71d7bb07b9a64f6f78ac4c816aff4da9

3. Deploy the Contract:

   Use the protostar declare-cairo0 command to deploy your contract:

   protostar declare-cairo0 --account-address 0x64b48806902a367c8598f4f95c305e8c1a1acba5f082d294a43793113115691 --max-fee auto --gateway-url http://localhost:5050/ --chain-id 1536727068981429685321 build/main.json

   This command deploys your contract (specified in build/main.json) to the local StarkNet chain.

Notes

• The --seed parameter in the docker run command is used to initialize the blockchain with a deterministic state.
• The PROTOSTAR_ACCOUNT_PRIVATE_KEY should be kept secure and not shared.
• The --account-address in the protostar command should be replaced with your account address.
• The --chain-id specifies the chain ID for the StarkNet network.

Conclusion

These instructions set up a local development environment for StarkNet, allowing you to deploy and test smart contracts locally.
