## Staking Service Launch

The staking service is a service where you can receive rewards every month just by holding eligible crypto assets (*). By using the staking service, you can efficiently grow your crypto assets.

**Staking Launch Date:**
Starting from 15:00 on Wednesday, April 1, 2026

**Eligible Staking Assets:**
- Ethereum (ETH)
- Oasys (OAS)

*Staking is a mechanism where you earn rewards by depositing your crypto assets and contributing to the network's verification and stable operation. An application is required for our staking service.
*Currently, only the browser version is supported. The app will be supported at a later date.

## Zero Staking Fee & Double Rewards Campaign

To commemorate the start of the staking service, we are holding a "Zero Staking Fee & Double Rewards Campaign."

**Campaign Period:**
Wednesday, April 1, 2026 – Tuesday, June 30, 2026

| Campaign Name | Normal | During Campaign |

| Zero Fee Campaign | 10% Fee | Free |
| Double Rewards Campaign | ETH: Max APY 2.5%, OAS: Max APY 8.5% | ETH: Max APY 5%, OAS: Max APY 17% |


**■ Zero Staking Fee Campaign**
For customers who stake on Coin Estate during the campaign period, the staking fee for that period will be waived.

**■ Double Staking Rewards Campaign**
For customers who stake on Coin Estate during the campaign period, the staking rewards for that period will be doubled.
*The doubling is based on our company's standard performance rewards. Normal conditions will apply after the period ends.

**Reward Distribution Date:**
- Normal Staking Rewards: Credited to your custody account around the 5th business day of the following month.
- Campaign Bonus Rewards: Credited to your custody account by the end of the month after next.

*The normal staking fee is 10% of the staking reward. The reward will be credited after deducting the fee.
*The maximum APY is an estimated annual percentage yield as of March 2026, calculated based on performance data from August 31, 2025, to March 31, 2026. It does not guarantee the maximum APY, which may fluctuate depending on the actual staking conditions of each crypto asset. The maximum APY is the annual rate before deducting fees.
*The double rewards campaign is applicable up to a maximum of 5 ETH and 10 million OAS (monthly average staking amount).
*Those who have been confirmed to have unstaked their assets by the distribution date are not eligible for the campaign.
