Preface: we made the decision to push this live sooner rather than later in order to get the community's feedback sooner rather than later. We will be making incremental improvements based on feedback.

Interacting with Contracts

MyEtherWallet now gives you the ability to interact with any contract on the Ethereum, Ropsten, or Ethereum Classic chain provided the contract address + contract ABI.

1. Go to https://www.myetherwallet.com/#contracts
2. Enter the address + ABI
3. Select the function. Some of these are read functions, some are write functions.
4. Enter additional information.
5. If it's a read function, a read button will appear. Enter any data (if it needs it) and click the read button. The fields below will be populated.
6. If it's a write function, a write button will appear. Enter any data (if it needs it) and click the write button. A popup will appear that asks for your key. From there you can see the amount to send (I think you always leave this at 0?) and the gas limit (which is estimated automatically for you.) You can then generate + send the transaction.

If you are interacting with contracts, we recommend using our Beta node (use the node switcher in the upper right corner to select ETH-beta) as it's way faster.
