Shardeum, a Layer 1 blockchain powered by dynamic state sharding, has made significant strides in scalability and decentralization. In preparation for its mainnet launch, Shardeum launched the Atomium Incentivized Testnet Campaign. The goal of this campaign was not only to rigorously test Shardeum’s network but also to engage a large community, encourage participation, and create a sustainable ecosystem. The results were outstanding, with hundreds of thousands of users actively involved across multiple stages of the campaign.
This case study highlights the key achievements across Stage 1, Stage 2, and Stage 3 of the Atomium campaign, showcasing how Shardeum leveraged its incentivized structure, powered entirely by Bandit, to build a robust and engaged community while thoroughly testing its network.

Overview: Shardeum’s Path Forward with Bandit
Shardeum’s testnet campaign was executed across three distinct stages, each increasing in complexity to evaluate the network’s performance and bring the community closer to the technology. Each task – from social media participation to running nodes was incentivized and tracked.
By integrating Bandit’s platform into all aspects of the Atomium campaign, Shardeum was able to build a large, engaged user base and test the network thoroughly ahead of its mainnet launch.
Stage 1: Community Onboarding and Initial Engagement
Tasks: In Stage 1, Shardeum focused on building awareness and bringing new users into the ecosystem. Powered by Bandit, this phase introduced users to the platform with tasks like:
- Following Shardeum on Twitter
- Joining the Shardeum Telegram Group
- Retweeting key threads and announcements
- Completing GitHub tasks, such as starring the Shardeum repository
- Refer Your Friends to Shardeum’s Incentivized Testnet
The referral system was fully integrated, allowing users to earn rewards for inviting others to join the campaign. For each referral, participants earned XP points, incentivizing both personal engagement and the act of expanding the user base.
Outcome: By the end of Stage 1, Shardeum had over 490K+ active referral participants and facilitated 480K+ transactions, establishing a solid foundation for community engagement and showcasing its capability to handle significant activity.
Stage 2: Advanced Engagement and Network Stress Testing
Tasks: In Stage 2, Shardeum deepened its engagement with more complex tasks designed to test its network infrastructure:
- Wordle Challenges: This offered an interactive and fun way for users to participate. These tasks were a clever way to blend entertainment with engagement, fostering regular participation from the user base.
- Node Setup & Staking: This provided participants with the opportunity to directly contribute to Shardeum’s decentralization efforts by setting up nodes and staking SHM tokens.
- Voting for Favourites: These tasks empowered users to take part in important community decision-making, further emphasizing Shardeum’s commitment to being a user-driven project.
- Retweeting and Subscribing: Participants consistently shared updates and subscribed to the newsletter, ensuring that the campaign reached a broader audience and that users stayed connected with the latest developments.
Outcome:
- Social Media Activities: Nearly 486K+ participants engaged through following, retweeting, and subscribing, expanding Shardeum’s visibility.
- Interactive Games (Wordle): 278K+ users played Wordle challenges
- Node Setup & Staking: 11K+ users set up nodes and staked SHM.
- Tower Challenges (Buidl Together): 278K+ users participated in collaborative tasks.
- Voting for Favourites: 322K+ votes were cast.
- Transaction Volume: The platform facilitated over 4M+ transactions in Stage 2
Stage 3: Advanced Technical Testing and Sustained Participation
Tasks: In the final stage of the Atomium campaign, Shardeum introduced more advanced tasks, powered by Bandit, to test the network’s scalability and performance under more complex scenarios. These tasks required deeper interaction from users while maintaining high engagement from the community.
- Participating in Quizzes: Shardeum continued to challenge users’ technical understanding through multiple quizzes. This helped ensure that participants were familiar with Shardeum’s network functionality and blockchain principles.
- Wordle Games and Tower Challenges: Interactive elements like Wordle games and collaborative Tower Challenges kept non-technical participants involved and engaged. These fun activities helped maintain excitement and a sense of community during the final stage of testing.
- Social Media Engagement: Users continued to follow, share, and retweet Shardeum’s updates on social platforms, further increasing the visibility of the testnet campaign.
- Node Setup & Staking: More participants set up nodes in Stage 3, with thousands of users contributing to network validation and staking SHM tokens.
Shardeum’s continued use of Bandit’s reward system successfully incentivized users to complete tasks and bring in more participants, ensuring sustained participation throughout the campaign.
Outcome:
- Social Media Activities: 301K+ participants engaged through various social media platforms, maintaining Shardeum’s presence and fostering community interaction.
- Quiz Participation: 275K+users completed quizzes
- Wordle Game Participation: 75K+ users played Wordle challenges.
- Node Setup: 14K+ users successfully set up nodes.
- Tower Challenge Participation: 75K+ users engaged in collaborative tower-building challenges.
- Voting for Favourites: 53K+ votes were cast.
- Transaction Volume: The platform facilitated over 6M+ transactions in Stage 3.
Conclusion: A Campaign Powered by Bandit’s Success
The Atomium Incentivized Testnet Campaign was a major success for Shardeum, achieving over 6 million transactions alone in Stage 3.
Shardeum was able to:
- Incentivize growth by offering rewards for participation and referrals.
- Thoroughly test the network across various tasks and technical challenges.
- Build a vibrant community of users actively engaged in the project ahead of the mainnet launch.
The integration of Bandit’s referral and engagement tools ensured that Shardeum not only met its technical goals but also created a strong foundation of active users ready to support the network post-launch.
Shardeum’s success with the Atomium campaign is a testament to the power of Bandit’s solutions, demonstrating how well-executed incentivization strategies can drive both network testing and community engagement.
