Production Checklist
Follow best practices when using Engine in a production environment.
Security
- Do not set the environment variable
ENABLE_HTTPS=true
. - Securely store access tokens and the thirdweb secret key. Rotate these credentials if they are compromised.
- Use labels to keep track of your wallets, admins, and access tokens.
- Use access token with expirations to grant time-bound access.
- Regularly review the admins list to remove inactive and former team members.
Cloud hosting
- Host Engine Docker on a cloud provider.
- Minimum specs: 1 vCPU, 2 GB memory (AWS equivalent: t2.small)
- Autoscale the instance count to increase inbound throughput and queuing capacity.
- Host Postgres DB on a cloud provider.
- Examples: AWS RDS, Google Cloud SQL, Heroku, Supabase
- Minimum specs: 2 vCPU, 2 GB memory (AWS equivalent: t4g.small)
Backend wallets
- Recommended: Use a wallet backed by AWS KMS or Google KMS. Wallet access is always recoverable and private keys are never exposed.
- If using a local wallet: back up the private key. Engine cannot recover private keys if the encrypted stored data is lost or corrupted.
- Ensure your backend wallets have sufficient funds. Consider using wallet webhooks to alert when your native coin balance is low.
