rate limits
We've introduced rate limits to improve the quality, reliability and fairness of the auction across the network. There are two levels of rate limiting.
unknown builders
By default unknown builders are subject to stricter rate limits than authenticated builders.
To become an authenticated builder simply ask us to issue you an API token and add it to your X-Api-Token header when sending through requests.
authenticated builders
Authenticated builders are subject to a bandwidth rate limit of 60 MB per slot per region.
Based on our analysis this should be more than enough for most use cases, but we'll be monitoring usage and may adjust it over time as needed.
managing rate limits
To ensure you get the most out of your rate limit we recommend:
getting an API token and authenticating your submissions
using SSZ encoding all submissions
considering implementing dehydrated bids or optimistic v3 which are more efficient and will allow for more requests per slot
ensuring your builder is set up to handle 429 (Too Many Requests) responses gracefully
testing your builder against our
hoodirelays to avoid unnecessary usage of your bandwidth limit onmainnet.
If you find that you need more bandwidth than the free tier, we do have a paid option available. Please reach out to smilingalex or the ultra sound team for details.
