Subtitle | How do smart contracts know external prices?
On-chain price feeds are generally triggered when a price change reaches a set threshold or at a fixed time.
Using the spot price from a single DEX pool as a price feed is very risky: when the pool is small, a single flash loan transaction can skew the price.
$LINK is the token of the Chainlink oracle network. Current price: 11.399.
Invest according to your own risk tolerance, and leave yourself some room.
