MyEtherWallet (MEW) offers three different wallet options which vary in the networks/coins they support.
All MEW wallets support ETH and all ERC-20 tokens (even the ones that are not yet supported anywhere else).
In addition, our multichain browser extension wallet Enkrypt supports Bitcoin (BTC), Ethereum Classic (ETC), Polygon (MATIC), BNB Smart Chain (BNB), Optimism (Layer 2 ETH), as well as Polkadot (DOT) and its parachains.
