The ADD (PLT) project has announced that they are performing a migration to a new token contract and updating the ticker from PLT to ADD during the week of February 22, 2021. 

We will support the migration for Poloniex PLT holders. Poloniex customers who hold PLT do not need to take any action at this time but here is some important information to keep in mind: 

• Starting February 19, 2021 around 21:00 UTC, PLT deposits, withdrawals, and trading will be disabled while we prepare to perform the migration in the coming week. 
• We will begin the distribution of the new token to all eligible customers at a ratio of 10 PLT = 1 ADD. Once the swap is complete, we will sunset our support for PLT and the new ADD token will persist on the exchange.
• We will enable deposits, withdrawals, and trading for the new token soon after the migration is complete.

We will keep you updated on our Support Twitter account.
