TronFi announced that they are performing a token swap from SAL to SLM over the coming days.

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

• Starting on Monday, September 21, 2020 around 14:00 UTC, SAL deposits and withdrawals will be disabled while we prepare to perform the swap. Trading has also been disabled while we prepare for the swap.
• We will begin the distribution of SLM to all eligible customers at a ratio of 1 SAL = 1 SLM. Once the swap from SAL to SLM is complete, we will sunset our support for SAL and SLM will persist as the sole SalmonSwap token supported on the exchange.
• We will enable SLM deposits, withdrawals, and trading soon after the swap is complete.
