Prerequisites

Before you begin, make sure you have:

A Circle Developer Console account
An API key created in the Console: Keys → Create a key → API key → Standard Key
Your Entity Secret registered

Step 1. Set up your project

Create a project directory, install dependencies, and configure your environment.

1.1. Create the project and install dependencies

mkdir erc8004-quickstart
cd erc8004-quickstart
npm init -y
npm pkg set type=module
npm pkg set scripts.start="tsx --env-file=.env index.ts"

npm install @circle-fin/developer-controlled-wallets viem
npm install --save-dev tsx typescript @types/node

mkdir erc8004-quickstart
cd erc8004-quickstart
python3 -m venv .venv
source .venv/bin/activate

pip install circle-developer-controlled-wallets web3 python-dotenv

1.2. Configure TypeScript (optional)

This step is optional. It helps prevent missing types in your IDE or editor.

Create a tsconfig.json file:

npx tsc --init

Then, update the tsconfig.json file:

cat <<'EOF' > tsconfig.json
{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "strict": true,
    "types": ["node"]
  }
}
EOF

1.3. Set environment variables

Create a .env file in the project directory and add your Circle credentials:
