Does MyCrypto support Bitcoin or other coins (LTC STEEM ZEC)?
ETC, all testnet networks (Ropsten, Kovan, Rinkeby), any other Ethereum-based network (
POA etc.) and any Ethereum Standard Tokens - aka "ERC-20" tokens.
You can use Shapeshift.io or another exchange to swap / convert / exchange your other coins into ETH or Ethereum tokens. However, you do not send those other coins directly to your Ethereum address.
We recommend Exodus.io as a client-side, multi-coin solution.
MyCrypto supports a lot of ERC-20 tokens by default, however, any missing ERC-20 token can easily be added to your local interface by following these instructions.
