Note: This article describes the process for moving assets you hold in MetaMask to the Binance centralized exchange (CEX). This is not the same thing as moving assets from MetaMask to the Binance Smart Chain.
If you are trying to transfer assets to Binance from MetaMask, please make sure you are following the guidelines to avoid a loss.
First of all, you have to understand that Binance is a centralized exchange that functions on a limited number of networks. (Ethereum mainnet, Binance Smart Chain, Polygon, etc.) So please make sure you're certain of:
- The network your tokens are currently on (the one you're sending from)
- Support for that network on the Binance exchange.
If you've already sent the tokens and Binance does not support the network, your funds are most likely gone for good. For further information, please contact Binance at https://www.binance.com/en/support.
After making sure that Binance supports the network, you will need to make sure that you have funds in MetaMask for gas fees on that network.
Please note that gas fees are paid in the native token of the network, for example:
- ETH for Ethereum Mainnet
- BNB for Binance Smart Chain
- MATIC for Polygon.
If you don't have tokens for the gas fees, you won't be able to send the assets to the Binance exchange.
Follow Binance's instructions here (for the US exchange) or here (for outside the US) to obtain the specific address for the token you're depositing within your Binance account. Copy this address and paste it into MetaMask when you are asked for the destination address.
