How the mood engine works

Most "dynamic" NFTs are a server updating a JSON file. Yours is a pure function of the market, evaluated the moment anyone looks at it.

The baseline

When your pet is minted (or fed, or transferred), the contract stores the live Chainlink price of its bonded stock as the baseline. That number is your pet's anchor: mood is never about where the stock is, only about where it is relative to the last time you cared.

The read

Every call to tokenURI() fetches the current Chainlink price, computes the move versus your baseline in basis points, and picks a mood:

• $.$ EUPHORIC, above +10%
• ^.^ HAPPY, +2% to +10%
• o.o NEUTRAL, between -2% and +2%
• T.T SAD, -10% to -2%
• x.x REKT, below -10%

The ASCII art, the colors, the glow, the metadata JSON: all of it is regenerated on-chain from that single number. Nobody updates anything. There is nothing to update.

The crab exception

CRABs are happy when the market goes nowhere. In the NEUTRAL band, a CRAB renders HAPPY. Fourteen percent of the collection is emotionally invested in your stock doing absolutely nothing.

When the feed sleeps

Stock feeds follow market hours and pause during corporate actions. When the feed is stale, your pet does not break and tokenURI() does not revert: it falls back to NEUTRAL and waits for Monday like the rest of us.
