Do prices in a contract update automatically from time to time, or are they fetched only when needed?
It’s worth understanding the two oracle models.
With pull-based oracles, prices are updated on-chain on demand. This can keep prices more up to date, but applications need to check whether a price is stale; otherwise, they may read an outdated price.
Verify information from multiple sources before acting—don’t rely on just one source.
$PYTH and $LINK are the tokens of the oracle networks Pyth and Chainlink, respectively.
