Battle Arena
Lock HUB. Support projects. Earn rewards.
Battle Arena is HUB Voting’s reward campaign system. Projects create campaigns with a token reward pool, and community members lock HUB to participate. When the campaign ends, participants get their HUB back plus a proportional share of the rewards.
Zero risk to your HUB — it’s returned 100% after the campaign. You only earn, never lose.
How It Works
Browse Campaigns
Visit the Arena to see active campaigns. Each one shows the project token, reward pool, time remaining, participants, and your estimated reward share.
Lock Your HUB
Choose a campaign and lock your HUB tokens (minimum 5,000 HUB). Vote for the campaign’s token during the active period to earn your share of the reward pool.
Campaign Ends
When the timer runs out, the campaign enters its claim phase. Your rewards are calculated based on the votes you earned during the campaign relative to all participants.
Claim Your Rewards
After the campaign ends:
- Your locked HUB is returned in full
- You receive your proportional share of the reward pool
- You have 6 months to claim — no rush
Campaign Tiers
Projects choose from 5 tiers when creating a campaign:
| Tier | Max Participants | Creator Deposit |
|---|---|---|
| Tier 0 | 100 | 0.0001 ETH |
| Tier 1 | 500 | 0.0003 ETH |
| Tier 2 | 2,000 | 0.0006 ETH |
| Tier 3 | 5,000 | 0.0012 ETH |
| Tier 4 | 10,000 | 0.0024 ETH |
Higher tiers allow more participants but require a larger deposit from the creator (returned after finalization).
Creation fee: 12,500 HUB (100% burned). This is separate from the ETH deposit.
Minimum HUB lock: 5,000 HUB per participant.
Voter Protection
Battle Arena is designed with multiple safeguards to protect participants.
6-Month Claim Window
After a campaign ends, you have 180 days to claim. This period is locked at campaign creation — it cannot be shortened by anyone.
Locked Rewards
The reward pool is held in the smart contract. The creator cannot withdraw while the claim window is active.
Full Transparency
Every deposit, lock, and claim is recorded on-chain. Verify everything on BaseScan.
Sweep Protection
Only after the 6-month window expires can the creator sweep unclaimed rewards.
Timeline: Campaign ends → 6-month claim window (your rewards are protected) → Creator can sweep unclaimed rewards

Eligibility Requirements

Presale Only — Only users who participated in the project’s presale on HUB Voting can join. Great for rewarding early supporters.
FAQ
Is my HUB at risk?
No. Your locked HUB is returned 100% when the campaign ends. The only HUB that gets burned is when you vote (separate from Arena).
Do presale buyers get a bonus?
Yes. Wallets that purchased at least 25,000 HUB in the presale earn +10% on every Arena reward. This is enforced on-chain in the smart contract and applies forever.
What if I forget to claim?
You have 6 months. After that, unclaimed rewards may be swept by the creator.
Can I join multiple campaigns?
Yes — as many as you want, as long as you have enough HUB to lock.
What tokens can be used as rewards?
Any ERC-20 token on Base. The project token being promoted can be on any chain.
How are rewards calculated?
Based on votes you earned during the campaign, not the amount of HUB you locked. The more you vote for the campaign’s token while it’s active, the larger your share of the reward pool.
