Meteora Quirks

Known issues to handle in your agent:

DAMM v2 fee rates on new launches can look implausible (30-50% of volume). This is a data artifact, not real fees.

/lps/top?sort_by=fees can return 500. Fallback to sort_by=volume.
DLMM events use PascalCase field names; DAMM v2 events use snake_case.
