[Ethereum] Move ERC20 tokens from Ethereum Wallet Contract to Account

accesserc-20myetherwalletwallet-contracts

In my Ethereum wallet i am trying to access my wallet conract. If I sync in light mode and import the wallet contract address it just stays there displayed, greyed out and nothing happens, no matter which ethereum wallet/geth version combination I try.

Or if I download the full block chain it stops short at the last 100 blocks and never fully syncs.

Basically my wallet contact doesn't show up in any case 🙁

It contains all my ERC20 tokens and I can't access them.

I have tried many combinations of Geth and Ethereum wallet versions to get the desired effect, but to no use. Apparently this wallet import issue will be fixed in 0.12 but I can't wait that long.

Is there a way to use MEW to do this or some other online wallet?

Thanks in advance

Peter

What method do you use for accessing your funds? Keystore file, private key string, mnemonic phrase, or hardware wallet? The tokens will always exist on the blockchain associated with your private key until you are able to access them.

You can probably get this working on the MyCrypto desktop app.

Download and install the app from https://download.mycrypto.com
Open the app and access your wallet using the method you have access to your ERC20 tokens on.
On the right-hand side of the app there is a "scan for tokens" option. If we have the token listed in our open-source repo (https://github.com/ethereum-lists/tokens) then it should show up there. If not, you'll have to add your tokens as custom tokens. Here is the documentation for how to do that: https://support.mycrypto.com/tokens/adding-new-token-and-sending-custom-tokens.html
TLDR: You'll need the contract address and number of decimals that the contract uses (18, 12, 9, 6, or 3 normally). Input them into the "Add Custom Token" prompt and submit it. Then you should see the tokens that you have for that contract address.

You can transfer them away if you need to, or just leave them there knowing that they're safe and sound. Feel free to message our support through the link at the bottom of that knowledge-base article if you need any further help. Best of luck!

Viewing the DAO token in the Ethereum Wallet

Follow the steps on daohub.org - Monitoring your balance to add the DAO token to Ethereum Wallet. In summary these steps are:

In the Ethereum Wallet, click on Contracts on the top right of the screen
Click Watch Token
Enter the Token Contract Address 0xbb9bc244d798123fde783fcc1c72d3bb8c189413
Enter the Token name The DAO
Enter the Token symbol: Ð
Enter Decimal Places: 16
Click OK
You should now have a The DAO custom token on your Ethereum Wallet contacts page.

Interacting with the DAO contract in the Ethereum Wallet

Follow the steps on daohub.org - Voting and other functions to add the DAO token to Ethereum Wallet. In summary these steps are:

In the Ethereum Wallet, click on Contracts on the top right of the screen
Click Watch Contract
Enter the Contract Name The DAO
Enter the Contract Address 0xbb9bc244d798123fde783fcc1c72d3bb8c189413
On the daohub.org - Voting and other functions page, click on SHOW JSON-INTERFACE button. (You can also get the the same JSON-INTERFACE text from The DAO - Contact Source Code).
Copy the JSON text in the text box below the button
Paste the JSON text into the JSON INTERFACE text box in the Ethereum Wallet
Click OK
You should now have a The DAO custom contract on your Ethereum Wallet contracts page.

ERC-20 – Does Ethereum Wallet/Mist Multisig Wallet Support ERC20 Tokens?

Update Feb 21 2018

Note that while the sending of ETH and tokens works, you cannot change the parameters of the multisig (add owner, remove owner, change owner, change daily limit). See https://github.com/bokkypoobah/EthereumWalletMultisigTest for further information.

The standard Ethereum Wallet / Mist multisig contract does support ERC20 tokens.

Here is a transaction of a Golem Network Token (GNT) transfer from a multisig contract - tx 0x4afd4e13bc80c7a9305b77f0f62058c8700ec6c92ad0c355f667af898903866b .

The multisig contract is at 0xf3f1f928fbe5d68b776005cad5350b49b42dfdde.

From the transaction data, you can see the execute(...) multisig function call:

Function: execute(address _to, uint256 _value, bytes _data)

MethodID: 0xb61d27f6
[0]:000000000000000000000000a74476443119a942de498590fe1f2454d7d4ac0d
[1]:0000000000000000000000000000000000000000000000000000000000000000
[2]:0000000000000000000000000000000000000000000000000000000000000060
[3]:0000000000000000000000000000000000000000000000000000000000000044
[4]:a9059cbb000000000000000000000000550bfe4a2691175e03e058d826829c3a
[5]:749b5f9700000000000000000000000000000000000000000000000053444835
[6]:ec58000000000000000000000000000000000000000000000000000000000000

a74476443119a942de498590fe1f2454d7d4ac0d is the GNT contract address.

And here is the portion of the GNT transfer function call.

a9059cbb  // web3.sha3('transfer(address,uint256)').substring(0,10) = "0xa9059cbb"
000000000000000000000000550bfe4a2691175e03e058d826829c3a749b5f97 // destination address 
00000000000000000000000000000000000000000000000053444835ec580000 // new BigNumber("53444835ec580000", 16)/1e18 = 6

The user trying to execute the transaction above had a few failed attempts using their multisig account to execute this ERC20 transfer transaction due to insufficient gas. The user increased the supplied gas and the transaction executed smoothly.
