Astar Brew Challenge (ABC) – Rules & Rewards
The Astar Brew Challenge (ABC) is designed for the Astar Contribution Score (ACS) campaign. Mint NFTs, collect ⭐️Stars, and earn ACS rewards.
How It Works
Every 10 days, Biru will receive a package of ACS points to distribute to ABC participants, and the amount of ACS points may vary in each season. Participants mint NFTs to get mint tx and earn ⭐️Stars, which contribute to their ACS rewards.
The challenge consists of two primary reward pools:
I. Daily Tx Rewards – Earn ACS every day based on daily mint tx.
II. Seasonal Leaderboard Rewards – Compete for ⭐️Stars rankings over a 10-day season.
I. Daily Tx Rewards
Daily Tx Rewards will be distributed according to Mint-Transaction-Weighted Allocation.
Starting February 21, 00:00 UTC, only users who complete more than 10 transactions (including Free Mint and non-Free Mint mints, requiring at least 11 transactions) will be eligible to share the daily mint rewards.
Wallet addresses with less than 11 daily mint tx will not be included to the calculation and distribution of daily ACS. However, they can still accumulate Stars and compete for seasonal leaderboard rewards.
- Your ACS share is based on your mint transaction percentage relative to the total mint transactions of the day. The more daily mint tx you created, the more ACS you can share on that day.
- If a user’s allocated daily ACS points are less than 1, they will not be distributed. Any undistributed daily ACS points will be accumulated into the seasonal leaderboard rewards.
- The daily tx count accumulation resets at 23:59:59 UTC every day.
- Daily ACS rewards will be distributed the next day.
II. Seasonal Leaderboard Rewards
We create a ⭐️Stars System, and users can get ⭐️Stars when they mint. Every minting on Biru official launchpad will generate ⭐️Stars to users, and non-free mint generate more starts than free mint!
- Free Mint (10 Stars per tx)
- A new official NFT collection is released daily.
- Each wallet can claim 10 free NFT per collection.
- Non-free Mint - ETH (200 Stars per tx)
- Includes official releases and artist collaborations.
- Non-free mints earn more Stars, increasing ACS rewards.
Non-free Mint - ASTR (400 Stars per tx)
- Includes official releases and artist collaborations.
- Non-free ASTR mints earn the highest number of Stars, further boosting ACS rewards.
Seasonal Leaderboard Rewards will be distributed after the end of the season. Top 10 users on the ⭐️Stars leaderboard rankings will share the leaderboard rewards as the following percentage:
| Rank | Percentage |
|---|---|
| 1st | 40% |
| 2nd | 20% |
| 3rd | 12% |
| 4th | 8% |
| 5th | 5% |
| 6th | 4% |
| 7th | 3% |
| 8th | 3% |
| 9th | 2% |
| 10th | 2% |
Seasons & Reset Mechanism
The Astar Brew Challenge will last as long as ACS campaign, from February 20th to May 30th. The campaign last for a total of 100 days, dividing into 10 seasons, each season 10 days. After each season, ⭐️Stars and total tx counts reset, and a new round begins.

FAQ
What is ACS campaign?
Astar Contribution Score (ACS) campaign is an ecosystem-wide score-based system designed by Astar official, and aims to reward users for contributing to the Soneium ecosystem after its mainnet launch. Users earn ACS points based on specific onchain activities. DApps will receive ACS and distribute them to their users, and ACS points earned throughout the campaign will be converted into ASTR tokens at the end of the campaign.
How to join the Astar Brew Challenge?
Anyone can participate by minting NFTs on Biru official launchpad. There are free and non-free minting options, each granting stars that contribute to ACS rewards.
Do I need to join at the beginning of a season?
No, you can join at any time. Your scores will count towards the current season, and past rankings will remain available for reference.
Is minting the only way to earn ACS points?
Can I earn ACS every day?
Yes. Daily tx ACS is distributed every day based on your transaction activity relative to the total transactions of the day.
What happens if my ACS share is less than one unit?
If your ACS allocation is less than 1 unit, it will roll over to the Leaderboard rewards for distribution at the end of the season.
Where and when can I see my ACS points?
- After we distribute the ACS points, users can see their ACS points on ACS official website.
We will distribute daily tx reward the next day, and users will be able to see their ACS after ACS dashboard updated (01:00 UTC every day). For example, the daily tx reward for 2/20 will be calculated and distributed on 2/21, and users can see the ACS record on website after the update on 2/22 01:00 UTC, and so on.
How is the leaderboard ranking order determined in case of a tie?
In the case of a tie, the ranking order is determined by the time the score was achieved—those who reach the score earlier will rank higher.
How often do the ⭐️Stars reset?
⭐️Stars reset every 10 days at the end of each season, at 00:00 UTC. A new season begins immediately after. For season 1, ⭐️Stars reset at March 1st 23:59:59 UTC.
