Announcement regarding Poloniex's lack of support for FXS token swaps and its delisting.

Dear Poloniex users,

According to the official FXS plan, FXS will undergo a token swap. After comprehensive evaluation, Poloniex has decided not to support this token swap and will delist the FXS trading market.

The specific arrangements are as follows:

• FXS deposits are now closed;
• Poloniex will cease FXS/USDT trading and delist the token on January 14, 2026 at 10:00 (UTC);
• FXS withdrawals will still be supported on Poloniex for 60 days after delisting.

Please note:

• Please do not deposit FXS tokens to avoid asset loss;
• To avoid asset loss, please withdraw your FXS tokens as soon as possible and contact the project team for a swap.

We sincerely apologize for any inconvenience this may cause. Thank you for your support!

Poloniex
