Engine updates - instant version updates, improved API validation, withdraws + more

Phillip Ho

Engine has been updated to v2.0.18. Here are some notable changes in the past few versions:

For cloud-hosted Engine customers, the primary account* for an Engine can trigger an version update from the dashboard UI.

⚠️ We recommend pausing critical traffic during this time as there may be up to a minute of downtime.

*The account that owns the subscription. We're working on better Engine management for teams in the near future!

All endpoints that accept an EVM address or transaction hash now enforce the type on input, returning a clearer message before the request fails further with a less obvious error (like "Contract not found" when provided a malformed address).

Docker build times have been reduced ~85% down to 7 minutes! This mostly impacts developers building Engine from source.

• Gas withdrawals from a backend wallet are more reliable by calculating the max amount of funds that can be withdrawn with the current gas settings.
• Reduced Redis usage when many jobs that fail to mine.
• More reliable "stuck nonce" health checks that alert our on-call. (Cloud-hosted only)

The team's focus is on internal alerting and deeper observability into all the dependencies of Engine.

Upcoming product improvements include smart accounts capabilities, more granular options to handle gas spikes, API performance improvements with the v5 SDK, improvements to Alert Notifications, and more. Stay tuned for more changelog updates!
