Limit frequency of free feed from oracle providers

Open xlc opened this issue 4 years ago • 0 comments

feed_values is free iff

  • price difference is greater than DeviationThreshold
  • OR last update is older than HeartbeatThreashold

Otherwise the feed is still valid, just we will charge the standard tx fee.
