Can I add Cardano to my Metamask Wallet?
No - Metamask Wallets only support Ethereum Virtual Machine (EVM) compatible blockchains like Ethereum, Layer 2's (Optimism or Arbitrum), Avalanche, Fantom, Fuse and others. There are no plans for MetaMask to add Cardano or support the native blockchain Ouroboros in the near future.
That said, the Ouroboros-based Cardano blockchain is releasing an upgrade called Vasil, which may in future support EVM and therefore be compatible with MetaMask. However, there is no official news on this as at time of writing.
How do I get a Cardano Wallet?
If you want to bridge to Ouroboros on Cardano, you will need to download the Daedalus Wallet. This is an open source wallet that was built for the ADA ecosystem and is the most commonly used wallet for Cardano.
The Daedalus Wallet is incredibly intuitive and easy to use, with in-built Cardano staking features and token swapping functionality.

Can I send Cardano tokens to Metamask?
You cannot send your Cardano (ADA) tokens to any Metamask wallet from a cryptocurrency exchange. This is because the Cardano tokens are unique to the Ouroboros blockchain and are not supported on other Layer 1 blockchains like Ethereum, Terra, Solana or Avalanche.
The only non-exchange wallet you can use is the Daedalus Wallet.
Final Thoughts
Cardano is a powerful blockchain for DeFi and NFTs, but it is not compatible with MetaMask. Currently, the most popular online wallet for Cardano is Daedalus. However, if you are looking to store your Cardano tokens securely, we recommend that you opt for an offline wallet like the Ledger Nano S which offers secure Cardano storage and staking. They also offer over 5,000 other cryptocurrencies and are the world's most trusted institutional-grade crypto wallet.
