Integrating without getting it wrong

1. Do not apply the multiplier twice

The Chainlink answer is the token price and already carries the multiplier. Multiplying it again is the single most common bug, and it is invisible until a token actually pays.

2. Do not label a token price as a share price

If your interface says NVDA and shows a number, say which one it is. Once a token has split those two numbers differ by a factor, not by a rounding error.

3. Do not assume a ticker identifies a contract

Several tokens on this chain carry the ticker of a real company and are not stock tokens. Match on the canonical address from the registry, never on the symbol.

4. Do not trust a midpoint when the market is closed

Issuer bid/ask spreads widen enormously overnight and at weekends. Read the spread before you read the midpoint, and degrade gracefully rather than printing a confident wrong number.
