But nobody wants to settle a payment on information that has gone stale. That is the attitude I want every contract to take toward a price. When you read an @WinkLink_Oracle feed with latestRoundData, you get the price and an 𝘂𝗽𝗱𝗮𝘁𝗲𝗱𝗔𝘁 timestamp. The timestamp is the date on the cheque. The docs recommend checking it against a 𝗺𝗮𝘅𝗶𝗺𝘂𝗺 𝗽𝗿𝗶𝗰𝗲 𝗮𝗴𝗲 before using the price. They are specific about how to pick that age: ➜ 𝗟𝗼𝗻𝗴𝗲𝗿 𝘁𝗵𝗮𝗻 𝘁𝗵𝗲 𝗵𝗲𝗮𝗿𝘁𝗯𝗲𝗮𝘁, the interval within which the feed is guaranteed to update ➜ 𝗦𝗵𝗮𝗽𝗲𝗱 𝗯𝘆 𝘆𝗼𝘂𝗿 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀, because a lending market and a slow game can tolerate different delays ➜ 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗽𝗲𝗿 𝗳𝗲𝗲𝗱, since heartbeats are listed pair by pair ➜ 𝗡𝗲𝘃𝗲𝗿 𝘀𝗸𝗶𝗽𝗽𝗲𝗱, because a convenient read without a timestamp check is a cheque nobody looked at The docs also warn about latestAnswer. It returns the price with no timestamp at all, which is like a cheque with the date torn off. A bank teller checks the date in two seconds. A contract can do it in one line, and the habit costs almost nothing. The freshness guidance is in the developer notes: https://t.co/BVkWssd0mw 𝗚𝗲𝗻𝘂𝗶𝗻𝗲 𝗶𝘀 𝗻𝗼𝘁 𝘁𝗵𝗲 𝘀𝗮𝗺𝗲 𝗮𝘀 𝗰𝘂𝗿𝗿𝗲𝗻𝘁. Check the date before you cash the price. @justinsuntron @WinkLink_Oracle #TronEcoStar
