Reward and Withdrawal
Q1: I see reward in the dashboard, but why does my Metamask display no reward token at all?
When your miners start, Arkreen Network will calculate how much reward will be distributed to your miners. You can visit Arkreen Network Console Page to withdraw reward to your wallet.
Click Withdraw item on the sidebar. There are 3 numbers on the withdrawal dashboard:
- Rewards: It's the total cumulative reward amount that has been distributed to your miners since your first miner started.
- Withdrawable: It's the amount you can withdraw right now. It's equal to Rewards minus all withdrawn reward in history.
- Balance: It's the ERC-20 token balance on the token contract on Polygon. Note that Balance is not always equal to Rewards minus Withdrawable, because you may transfer your withdrawn token in wallet to someone else.
If it's your first time withdrawing reward, click Add Token to Metamask button to add asset to your Metamask. Then, click Withdraw button to withdraw reward to your wallet. The Withdraw Record table shows all your historical withdrawal records.
If the withdrawal should fail, see How to retry withdrawal.

Q2: How can I add token into my Metamask?
You can add token into Metamask by clicking Add Token to Metamsk button in Arkreen Network Console's Withdraw page.
As an alternative, you can also add the token contract address to Metamask to manually import the token asset.
The mainnet AKRE smart contract is deployed on Polygon mainnet at address: 0xE9c21De62C5C5d0cEAcCe2762bF655AfDcEB7ab3

Note: The testnet token tAKRE is no longer effective since mainnet launch. For users who participated in the testnet stage, the tAKRE was already converted to AKRE during Mainnet Transition. Though tAKRE has actually completed its historical mission and currently serves no purpose, it will not disappear from your wallet automatically. In addition to adding AKRE to your wallet, you should manually hide tAKRE to avoid confusion.

Q3: Can I use a wallet other than Metamask, e.g., Rainbow?
Yes. Arkreen supports various wallets through WalletConnect. Though all wallets are not tested, any Polygon-compatible wallet supported by WalletConnect should work with Arkreen. See WalletConnect Explorer for details.
For wallets other than Metamask, you have to manually import the token into your wallet. See Q2: How can I add token into my Metamask? for the token contract address.
Q4: I found a token pair on Uniswap for AKRE and USDC. Can I buy AKRE from this token pair?
Arkreen initiated an AKRE-USDC.e trading pair on Uniswap V3. The trading pair smart contract is deployed at Polygon mainnet address 0x65906dbdfca73c67cf35744864d2f3f9f71a8c44.
DO NOT operate on the obsoleted tAKRE-USDC Token Pair any more. The testnet token tAKRE is no longer effective since mainnet launch.
Q5: How my Smart Plug gets rewards?
A Smart Plug's rewards are composed of the baseline rewards and offset rewards.
See User Guide for Arkreen Smart Plug for details.
Q6: I withdrew my reward but it failed somewhere. The withdrawn reward is neither in Withdrawable amount nor in my wallet. How can I get it back?
Withdrawal operation may fail in some cases. Example causes include temporarily losing the connectivity to the Internet, the wallet (e.g. Metamask) server is too busy to accept the transaction requests, not enough POL to pay for the gas fee, and user rejecting the transaction.
Don't be worried. It's recommended trying withdrawal on a PC instead of a cellphone to get rid of the potential compatibility issues on cellphones. Please also check if there is enough POL in the operating account. Then, simply check the withdrawal history on the page. If there is a failure record showing a "Withdraw" button, click on the button in this record to retry the withdrawal.


In this case, try to configure your wallet with a different RPC URL and retry withdrawal from the failed withdrawal record. A list of the most popular RPC nodes for Polygon can be found at https://www.alchemy.com/chain-connect/chain/polygon-pos.
If you are using Metamask, you can find the configuration in Metamask's Settings -> Networks -> Polygon Mainnet. Set the "New RPC URL" to an alternative RPC URL in the above list and then, retry the withdrawal.
