Who sends price feeds on-chain?
Push-based price feeds usually update when the price deviates beyond a set threshold or at a fixed heartbeat interval.
Pull-based feeds are brought on-chain as needed, so prices can be updated more promptly. However, the application must check whether the price is stale; otherwise, it may use an outdated price.
$PYTH and $LINK are the tokens of the oracle networks Pyth and Chainlink, respectively.
Markets are always uncertain, so think ahead about what to do if your judgment is wrong.
