According to official news from Odaily, Coinbase will suspend Polymath (POLY) trading on Coinbase.com, Coinbase Exchange and Coinbase Prime platforms at around 3 a.m. on December 6, Beijing time. POLY is migrating from Ethereum to Polymesh Network (POLYX). Coinbase currently has no plans to support POLYX. The deadline to upgrade POLY to POLYX is January 31, 2024. If users still hold POLY after the trading suspension, they need to use the upgrade bridge and self-hosted wallet to convert POLY to POLYX before the upgrade bridge closes on January 31, 2024, otherwise they may face significant losses of assets.
