On September 28, 2023, OKX launched an exclusive ZBC airdrop campaign for BETH holders. This event offered participants the chance to earn rewards by increasing their BETH holdings during the promotional period. Below, we break down the campaign’s eligibility requirements, reward calculations, and participation steps.
Campaign Overview
The ZBC airdrop campaign was designed to reward active BETH holders. BETH represents staked Ethereum and offers users ongoing staking rewards. During the campaign, participants who increased their average BETH holdings could earn additional ZBC tokens.
Eligibility Criteria
To qualify for the airdrop, users needed to meet the following conditions:
- Stake a minimum of 0.1 additional ETH to receive BETH at a 1:1 ratio between September 28, 2023, at 10:00 AM WIB and October 12, 2023, at 10:00 AM WIB.
- Maintain a net average increase of at least 0.1 BETH throughout the campaign period.
Note: Ongoing on-chain rewards from pre-campaign BETH holdings were also considered part of the qualifying balance increase.
How to Acquire BETH
Users could obtain BETH through the following methods:
- Staking ETH directly via the platform’s dedicated staking section.
- Engaging in spot trading for BETH trading pairs, such as BETH/USDT and BETH/ETH.

Campaign Rules
The campaign used a snapshot mechanism to determine reward eligibility:
- A baseline snapshot of each user’s BETH balance was taken on September 28 at 9:00 AM WIB. Balances above 0.1 BETH in Funding, Trading, or Grow accounts were considered the baseline.
- Daily snapshots were taken throughout the campaign period. The average increase in BETH holdings above the baseline determined a user’s reward share.
Reward Calculation
The airdrop reward was calculated as follows:
- Individual Reward = (Individual Average BETH Increase ÷ Total Average BETH Increase on OKX) × Total Reward Pool
Users also continued to receive standard ETH staking rewards distributed daily.
Example Calculation
- User A had a baseline balance of 100 BETH.
- Daily snapshots showed balances of 105, 109, and 101 BETH on three consecutive days.
- The average increase was calculated as: (105 + 109 + 101) ÷ 3 – 100 = 5 BETH.
- Assuming a total platform-wide increase of 1,000 BETH and a reward pool of 4,295,000 ZBC, User A’s reward would be:
(5 ÷ 1000) × 4,295,000 = 21,475 ZBC.
