Goal

Invoke transactions on your Braavos account from the Starknet command line tool

Setting up the environment

This tutorial uses alpha-goerli testnet.

• Open a Braavos account on alpha-goerli
• Get some ETH for that account, using the Starknet faucet https://faucet.goerli.starknet.io/
• Go to settings in your Braavos wallet, and copy the address and private key from the wallet
• Create the folder .starknet_accounts in your home directory (note the dot prefix)
• Create a json file in that folder called starknet_open_zeppelin_accounts.json the file should contain the following:

{"alpha-goerli":
   {"__default__":{"address":"YOUR_ACCOUNT_ADDRESS",
                   "private_key":"YOUR_ACCOUNT_PRIVATE_KEY"}
   }
}

• Add an environment variable (add it to your .bashrc/.zshrc to be available for all future shells)

  export STARKNET_WALLET=starkware.starknet.wallets.open_zeppelin.OpenZeppelinAccount

Building The Transaction

Fetching the contract ABI

Let’s choose a contract to interact with. We will use an ERC20 test token, and execute a mint transaction. The token address we will use is 0x7394cbe418daa16e42b87ba67372d4ab4a5df0b05c6e554d158458ce245bc10

In order to execute a transaction on a contract, we need to get the contract ABI JSON file. We do this using the StarkNet CLI, and a JSON command line tool called jq. install jq by running on linux:

apt install jq

on mac: brew install jq
