- Issue entries / remove entries transactions
- Winner declaration transactions
Setup Steps (Recommended)
- Create a dedicated signer wallet just for provider automation.
- Fund it with a safe working amount of Base Sepolia ETH for gas.
- Store the private key securely (secret manager or encrypted env).
- Save signer in Provider Dashboard API Integration section.
- Test with small transactions before high-volume usage.
Security Best Practices
