Polkadot is its own network and is completely separate from Ethereum or any other chain. Wallets like MetaMask or MyCrypto only support the Ethereum network, and you cannot use them to store your DOT.

You can only store DOT in a Polkadot address on the Polkadot network. Polkadot addresses always start with 1 (Polkadot format) or 5 (generic Substrate format), as opposed to Ethereum or BSC addresses, which start with 0xYou can find some wallets that support Polkadot in this article.

There might be a Polkadot integration for MetaMask in the future, however, at the time of writing, we are not aware of any working solution yet. 

If you mistakenly withdrew DOT to MetaMask from an exchange like Binance, you sent a "wrapped" token rather than the native DOT token. You can find more information on this in this article


The contract address shown on sites like CoinMarketCap, which is able to be added as an asset in MetaMask, is for DOT-pegged (wrapped) versions of the token. Don't confuse this with Polkadot's native DOT token.
