👑Yield rewards

How to claim yield rewards generated by your zkCRO, vETH and vUSD holdings

The Cronos zkEVM network hosts natively yield-bearing cryptocurrencies such as zkCRO, vETH and vUSD, powered by Veno Finance, that enable users to accumulate yield rewards simply by holding them. The reward distribution mechanism is different for zkCRO on one hand, and vETH and vUSD on the other hand.

zkCRO Rewards

The exchange rate between zkCRO and CRO is expected to reflect not just the CRO staked originally to obtain zkCRO, but also the accumulated rewards.

When staked CRO generates more CRO, the value of zkCRO increases relative to CRO. Therefore, as a token holder you do not need to take any action to claim your rewards.

When you un-stake or sell your zkCRO, you receive the value of the CRO that you originally staked, as well as any accumulated rewards since then (unless there is a slashing event).

vETH & vUSD Rewards

vETH and vUSD are ERC20 tokens which aim to follow the value of ETH and DAI (a USD stable coin) respectively. Therefore, the value of vETH relative to ETH does not increase to reflect accumulated rewards, nor does the value of vUSD relative to DAI.

As a token holder, you need to manually claim your rewards from the smart contracts. You can do this at regular intervals, for example every month.

Tracking your rewards

All rewards can be viewed on the Cronos zkEVM Rewards page. Pending rewards are accumulated daily, but they only become claimable after a few days. On the Rewards page, you can track both your immediately claimable vETH and vUSD rewards, and the other pending rewards.

Pending rewards are updated every time that a Cronos zKEVM transaction batch is finalized on Ethereum, which is every day on average. These rewards become claimable after 5 transaction batches have been finalized on Ethereum, which could take 4-7 days on average depending on network traffic.

Claiming your rewards

On the Rewards page, head to the “Yield you earned” section. Please refer to the user guide below for detailed instructions.

Expiry date of rewards

Unclaimed rewards will expire 2 years after they have been earned.

Special case of vETH and vUSD locked in dapps

If you have deposited vETH or vUSD into a smart contract belonging to a dapp protocol, such as H2 Finance (a DEX), it is the dapp who is entitled to claim the rewards. Each dapp will decide how they redistribute these rewards to their users, and you should expect them to communicate clearly about it.

How to claim vETH/vUSD rewards

1. Head to https://zkevm.cronos.org/rewards (which currently redirects to /missions) and connect your wallet.

2. Once you have connected your wallet, you will be able to see the vETH/vUSD yield you have earned. Click “Claim Tokens” to claim the reward.

3. Under “Claimable Rewards”, click “Claim”. Proceed with the transaction approval on your wallet.

4. You have successfully claimed your rewards. Click the “History” tab to see the claim history.

vETH & vUSD deposited into dapps

When any vETH or vUSD are deposited into a dapp’s smart contract, all rewards are earned by the smart contract. Dapps will usually distribute the rewards back to their community. It is up to each dapp and their community to decide on how they distribute the rewards earned.
