Local development

npm install
npm test

Store the deployment key in Hardhat's encrypted keystore. Never paste it into chat, commit it, or put it directly in the configuration:

npx hardhat keystore set DEPLOYER_PRIVATE_KEY

npm run estimate:base
npm run deploy:base

The deployment script writes public addresses and transaction hashes to deployments/base.json.
