At this time Gemini can only accept ETH and ERC-20 token transfers sent over the main Ethereum network. We do not accept token transfers sent over BNB Chain (formerly Binance Smart Chain) or (BEP20/BEP2 Tokens). BNB is its own blockchain designed for Binance customers.
At this time Gemini is not able to recover funds sent to the exchange via BNB Chain (formerly Binance Smart Chain). BEP20/BEP2 tokens deposited to Gemini will be documented and we will be sure to contact you if we are able to recover the tokens at some point in the future.
Although BEP20 tokens use the same address format as Ethereum, they are separate networks. When withdrawing from Binance it is important to note the warning they provide when sending tokens over the BNB Chain.
