The sixth parachain slot auction on Kusama has officially launched, marking another pivotal moment in the evolution of the Polkadot ecosystem’s canary network. As a governance council member, PolkaWorld participated in voting for Motion 346, which initiated this highly anticipated auction round. With several innovative projects vying for a limited number of slots, the competition is fierce — and the rewards for supporters are substantial.
This article breaks down everything you need to know about the current auction cycle, including timing, participating projects, their crowdloan mechanics, and potential returns for KSM contributors.
Auction Timeline and Structure
Kusama’s parachain slot auctions follow a unique "candle auction" model designed to prevent last-minute bidding manipulation. Here's the current schedule:
- Bidding Period: 27,000 blocks (~45 hours)
- Randomized End (Candle Phase): 5 days of unpredictable closure
- Winner Selection Window: Final 3 hours to confirm the highest bidder at the random endpoint
- Lease Start: September 3 (Lease Period 15)
During the auction, all projects running crowdloans automatically place bids based on the total KSM locked by their supporters. The project with the highest bid at the randomly selected candle end wins the slot.

Top Projects in the Running
As of publication, 16 projects have launched crowdloan campaigns on Kusama. Below are the top five by KSM raised, along with detailed insights into their reward structures and participation incentives.
1. KILT Protocol – 208,175 KSM Raised
KILT aims to revolutionize digital identity with self-sovereign credentials. Their crowdloan offers strong incentives:
- Reward Pool: 4.5 million KILT tokens
- Hard Cap: 220,000 KSM
- Governance-Distributed Rewards
If the cap is reached, every 1 KSM contributed earns at least 25 KILT tokens. If contributions fall short, rewards increase proportionally. Notably, BOTLabs (the entity behind KILT) will vote but won’t claim any rewards — ensuring fairness for community contributors.
Rewards will be distributed under KILT’s decentralized governance once the network achieves full decentralization.
2. Calamari (Manta Network’s Canary Chain) – 103,231 KSM Raised
Calamari brings privacy-focused DeFi to Kusama with its zk-powered infrastructure.
- Reward Pool: Up to 3 billion KMA (30% of total supply)
- Hard Cap: 300,000 KSM
- Tiered Hard Cap Mechanism
To discourage irrational bidding wars, Calamari uses a three-tier hard cap system:
- First Tier (100,000 KSM): 1 billion KMA unlocked
- Second Tier (200,000 KSM): Additional 1 billion KMA
- Third Tier (300,000 KSM): Final 1 billion KMA
Each contributor receives a fixed 10,000 KMA per 1 KSM, regardless of total contributions — a rare and user-friendly model.
Additional bonuses include:
- Top 500 contributors: +10% bonus
- Next 500 contributors: +5% bonus
- Referral rewards: +2.5% for both referrer and referee
This structure encourages early and strategic participation.
3. Heiko (Parallel Finance’s Canary Chain) – 32,394 KSM Raised
Heiko is building an algorithmic lending and borrowing platform tailored for the Kusama environment.
- Reward Pool: 25 million HKO
- Hard Cap: 400,000 KSM
- Dynamic Reward Formula
Rewards are calculated as:
HKO per KSM = Total HKO Pool / Total KSM Collected
At maximum cap, contributors earn at least 62.5 HKO per KSM. Lower totals mean higher individual rewards.
Once Heiko secures a slot, HKO rewards begin a 12-month linear release, promoting long-term holder engagement.
4. Basilisk (HydraDX’s Canary Chain) – 33,868 KSM Raised
Basilisk is positioning itself as a leading automated market maker (AMM) and liquidity hub on Kusama.
- BSX Reward Pool: 1.5 billion BSX (15% of total supply)
- HDX Compensation Pool: Up to 56.8 million HDX
- Hard Cap: 222,222 KSM
Basilisk uses a time-based reward multiplier:
- Maximum (1x) during first 45 hours
- Linear decline to 0x over final 5-day candle period
Early contributors are strongly incentivized — delaying participation can cut rewards by up to half.
Additionally, contributors receive HDX tokens to offset opportunity costs from locking KSM:
- Up to 30% compensation when trailing in bids
- Decreases to 5% when leading by 20%

5. Altair (Centrifuge’s Canary Chain) – 30,933 KSM Raised
Altair enables real-world asset (RWA) tokenization and financing through decentralized credit pools.
- Reward Rate: 400 AIR per 1 KSM
- Hard Cap: 200,000 KSM
- Bonus Incentives
Early birds who contribute within the first 48 hours receive a +10% bonus. Referrals grant both parties a +5% bonus. Those contributing over 10 KSM may qualify for exclusive future rewards.
Reward distribution starts with 25% immediate release, followed by linear vesting over 48 weeks, balancing liquidity and long-term alignment.

Frequently Asked Questions
Q: What is a parachain slot auction on Kusama?
A: It’s a candle-style auction where blockchain projects compete for limited parachain slots by locking KSM via community-supported crowdloans.
Q: How do I participate in a crowdloan?
A: Visit the official website of a participating project, connect your wallet (e.g., Polkadot.js), and lock your KSM for the duration of the lease.
Q: Can I lose my KSM in a crowdloan?
A: No — your KSM is locked, not spent. It will be returned after the lease ends (typically ~6–9 months), minus transaction fees.
Q: What happens if my chosen project doesn’t win?
A: Your KSM is safely returned to you. Only winning projects retain locked tokens for the lease period.
Q: Are crowdloan rewards taxable?
A: In many jurisdictions, yes — token rewards may be considered taxable income upon receipt. Consult a tax professional for guidance.
Q: When will I receive my reward tokens?
A: Distribution varies by project — some start immediately upon launch, others after vesting periods. Check each project’s release schedule.
