# May 20, 2022. The Polygon(Matic) chain will be upgraded.
Dear CoinPocket users,
The Polygon(Matic) chain will be upgraded at 14:30 pm UTC on May 20, 2022. During the upgrade period, transaction records and price updates might be affected. The estimated upgrade time is one hour, it will be completed at 15:30 pm UTC. Your assets are stored on the chain, the upgrade will not affect asset security. Please wait with patience. Please don't trust anyone who claims to be an official. Anyone who directly communicates with you is a scammer! Don't share the private key and secret recovery phrase with anyone, please be vigilant! Sorry for the inconvenience!
