Become a Worker

Get Tokens

Create a


You can send your personal digital currency (PDC) token to WORK to become a worker for it.  Your job as a worker is to add value to the Workchain, for which you can be rewarded with a share of the ETH in the worker pool.


Login to your MyEtherWallet (MEW) account


Click on the 'Contract' drop-down, then 'Interact with Contract'.

Next, enter the contract address for your PDC token you want to add to WORK.

To find out the contract address for the tokens you want to send...

Note: If you want to add the tokens of another Wapp, enter its token address.


Then, paste some code into the 'ABI/JSON Interface' box. You can find that code on the Ethereum Github, or in the toggle box below. 

Copy the following code and paste it into the ABI box.

After you've pasted it, click the 'Continue' button


In the 'Select an Item' drop-down, chose 'approve'.


New input boxes will appear. Enter the ​WORK contract address.

(Note: WORK has 2 addresses. The token address is what you used to add a custom token to MEW. It is not the same as the address you used to get WORK tokens, which is the contract address.)

Also enter the number of whole tokens you want to send plus 18 zeros. (No decimals, unless you convert it into the uint256 value.

Enter the 'uint256' value. If you want to send 100 tokens to the contract, for example, you'd enter 100000000000000000000. To easily and correctly convert a value just check out this page.


Click the 'Write' button and confirm the transaction. If you receive an error, increase the gas limit manually to 300,000 (with whatever gas price you'd like).

If you are using MyCrypto for this and getting errors.. see here


Once you have verified that transaction is successful from Etherscan, the next step is to actually send the tokens to WORK. This is done by interacting with the WORK contract itself. Repeat step 2, above, but this time enter the ​WORK contract address (what you used to get tokens).

Paste the ABI code, which can be found on the Workchain Github or copy and paste the text more easily from here.


In the 'Select an Item' drop-down search for the 'sendExternalTokens' function (6th from the bottom). Also fill out the other fields, as noted below.


Click 'Write' and confirm the transaction. If you receive an error, increase the gas limit manually to 300,000.

That's it! You're done. Your tokens should now be in the WORK contract and will be distributed in the next pay period.

At the end of each pay period, the 'disributionSnapshot' function must be called by 1 WORK participant before rewards can be distributed or new validations can occur. This does not need to be called by everyone. Please refer to the 'Calling Functions in an Wapp' page. This only needs to be done once after the end of each pay period, and anyone can do it. There is no deadline for calling the function, however. If this call is missed for 5 periods in a Wapp, for example, the function just needs to be called 5 times in a row. (But note that workers will need to sign for distributions before the end of the following period.)

Before you receive your worker reward distribution, however, you need to approve of the work performed by the Workchain. This is done by adding the first digit of your wallet address and the number of the day of the month. You then turn this into an ETH decimal value by adding seven zeros in front of this number.

If your local date is November 5, for example ("5"), and the first digit of your wallet address is "2" then you would send 0.00000007 ETH to the contract address to sign for your distribution. (There is no need to worry about timezones.)

As a worker, you must claim your reward before the end of the following pay period. Otherwise, your reward will revert back to the pool and you must get re-validated for the period.
