There's an Error When I Try to Make a Transaction

MEW supports many networks, but when you are sending a transaction the other address needs to be on the same network. If it's not, you may be warned that the address doesn't match the network. (If you want to move tokens to a different network, you can use bridging in MEW Portfolio or MEW Mobile).

If you’re trying to send an old token that has launched a mainnet network that's not EVM compatible, you will likely need to send this crypto to an Ethereum address at an exchange like Binance to make the swap to mainnet.

Some supported chains may have different address formats than Ethereum's "0x....". If you are trying to send to an address in the format required by an exchange and it's not working, please reach out to us at support@myetherwallet.com for further assistance.

The checksum version of your address is the version that includes both capital and lowercase letters, for accuracy. The address itself is not different and does not affect the transaction. See our article about checksummed addresses for more info.

You can find the checksummed version by searching your address on a block explorer like ethVM, but many wallets (including MEW) will convert to the checksummed version automatically.

All transactions on the Ethereum blockchain require ETH for the fuel to make transactions happen. If you need more ETH, you can buy it directly in MEW Portfolio, MEW Mobile app, or Enkrypt browser wallet.

This gas fee is not set or collected by MEW. It goes to the validators that keep the blockchain running and secure, and is necessary for the function of the network. See our 'What is gas' article for more information about the network fee.

Please reach out to us at support@myetherwallet.com with as much information as possible so we can look into it.
