Price Feeds

Hey,

I have been trying Pyth on Sui and have couple questions – appreciate your help.

  1. Could you please share, for what reason when I call update price feeds, price info objects collect 1 MIST? Sui Transaction Block - SuiVision

  1. Is that correct to say that attestation_time of PriceInfoObject is the timestamp that Pyth relay on when validate the staleness/freshness of the PriceInfoObject?

    I’m just wondering on what we should relay — attestation_time or arrival_time?
    (this is for client_side)

Thanks

Hello,

  1. We do charge a fee for updating a price feed. The fee so far has just been a minimal one (1 mist). In the future, the fee may be changed (And we will communicate this in advance). But for the time being, there’s no plan to change it.
  2. attestation_time is a old field. It’s being set to some other timestamp right now. It’s not going to be totally wrong or anything, but its better to not make assumptions on it. I would suggest using arrival_time.
