Event duration: May 31, 18:00 - June 30, 18:00 UTC+8

How to participate:

Download the Gate APP, click on DEX, enter “Earn” via the Wallet homepage or Wallet activity page, then select the “Reward Fund” zone to participate.

Simply stake USDD or USDT via the USDD Earn protocol on the ETH network to earn a stable 4% APY and an additional 20,000 USDD reward.

Your daily reward = (individual staking amount / total staking amount of all users) × total daily reward, the more you stake and the longer the duration, the greater the returns.

Important Notes

1. This Reward Fund activity is jointly initiated by USDD official and GateDEX, with the reward claiming channel supported by GateDEX;
2. Before the event starts, the Reward Fund system will calculate and display an estimated APY based on the total TVL of USDD in the USDD Earn protocol on the ETH network, combined with the total prize pool of this activity. After the event begins, the real-time Boost APY will be calculated based solely on the total USDD staking amount invested by users participating through the GateDEX platform during this event. Therefore, the APY during the activity will fluctuate dynamically with participation, and the final earnings are based on the real-time APY.
3. During the Reward Fund activity, users need to enter the Gate App’s GateDEX mode, and complete a staking investment of any amount of USDD or USDT in the USDD Earn protocol under the “Finance/Earn” section to be considered as successfully participating in this activity. That is: during the event, the first USDD or USDT staking transaction in the USDD Earn protocol by the user, within its settlement cycle (1 hour), will be regarded as the user's first Reward Fund settlement cycle for this event.
4. During the Reward Fund activity, at the end of each settlement cycle (1 hour), the system will record the sUSDD holdings corresponding to each participating user’s staking behavior on the ETH network via the GateDEX platform, and use this as the user’s individual investment share for that cycle. sUSDD holdings obtained through other channels (including but not limited to protocol official staking, on-chain transfers, etc.) will not be included in the user’s investment share for this Reward Fund activity.
5. The Reward Fund tokens for this activity are USDD tokens on the ETH network. Rewards generated in the previous settlement cycle (settled hourly) will be settled in the next cycle. Settled rewards can be accumulated and claimed at any time, unaffected by the activity end time.
6. It takes some time for the system to settle the Reward Fund and synchronize user reward data to the smart contract; there may be slight delays in data updates.
7. When staking, users can pay with USDD or USDT. When paying with USDT, the smart contract will automatically convert USDT to USDD via PSM at a 1:1 lossless exchange and invest it into the protocol. Therefore, regardless of which token is used for staking, the investment receipt token obtained will be the same sUSDD.
8. When redeeming, whether choosing USDT or USDD, the same staking receipt token sUSDD will be consumed. If redeeming with USDT, the smart contract will automatically convert the redeemed USDD back to USDT via PSM at a 1:1 lossless rate and send it to the user’s wallet address.
9. When claiming rewards, whether on the USDT investment page or the USDD investment page, the same reward amount will be received. When a user successfully claims rewards on one page, the claimable amount on the other page will be reduced correspondingly.
10. All investment operations involved in this activity require ETH as Gas fee on the ETH network. Please ensure your wallet has sufficient ETH balance.
