The sixth parachain slot auction on Kusama has officially launched, marking another pivotal moment in the network’s decentralized evolution. As a member of the Kusama Council, PolkaWorld participated in the approval of Motion 346, which formally initiated this highly anticipated auction cycle.
Kusama continues to serve as a canary network for Polkadot, enabling teams to test new features, governance models, and economic mechanisms in a live, high-stakes environment. These candle-style auctions are central to how projects secure long-term parachain slots—dedicated blockchain spaces that allow them to connect natively to the Kusama relay chain and benefit from shared security, scalability, and interoperability.
Auction Timeline and Mechanics
The current auction phase lasts 27,000 blocks, equivalent to approximately 45 hours, followed by a 3-hour randomized ending period (candle phase), during which the final winner is determined. This candle mechanism helps prevent last-second bidding manipulation.
The lease period begins on September 3, with successful bidders securing their slots for up to 15 lease periods—each lasting about six weeks. Projects raise support through crowdloans, where KSM holders contribute their tokens to help fund a bid in exchange for project-specific rewards.
At the time of writing, 16 projects have launched crowdloan campaigns on Kusama. According to auction rules, all crowdloan participants automatically place bids equal to their total committed KSM at the start of each auction. The highest bidder is displayed on polkadot.js.org, though rankings may shift during the candle phase.
Currently leading the pack is KILT Protocol, followed closely by other innovative Layer 1 and DeFi-focused parachain candidates such as Calamari (Manta’s canary network), Heiko (Parallel Finance’s testnet), Basilisk, and Altair (Centrifuge’s Kusama deployment).

Leading Projects in the Auction Race
KILT Protocol
- KSM Raised: 208,175
- Reward Pool: 4.5 million KILT tokens
- Crowdloan Cap: 220,000 KSM
KILT has allocated 4.5 million KILT tokens as incentives for contributors. These rewards will be distributed under KILT governance once the network achieves full decentralization. Notably, BOTLabs—the entity behind KILT—will participate in voting but will not claim any reward share.
With a cap of 220,000 KSM, contributions beyond this threshold will not be accepted. If the cap is reached, every 1 KSM contributed earns at least 25 KILT tokens. Lower participation means higher individual rewards.
Calamari (Manta Network’s Canary Chain)
- KSM Raised: 103,231
- Reward Pool: Up to 3 billion KMA (30% of total supply)
- Crowdloan Cap: 300,000 KSM
Calamari employs a unique tiered hard cap system designed to promote rational bidding:
- Tier 1: 100,000 KSM → 1 billion KMA rewards
- Tier 2: 200,000 KSM → 2 billion KMA
- Tier 3: 300,000 KSM → 3 billion KMA
This structure ensures that only necessary funds are raised, reducing economic strain on the ecosystem. Contributors receive a fixed rate of 10,000 KMA per 1 KSM, regardless of total contributions.
Additional bonuses include:
- Top 500 contributors: +10% bonus
- Ranks 501–1000: +5% bonus
- Referral rewards: +2.5% for both referrer and referee
Heiko (Parallel Finance’s Testnet)
- KSM Raised: 32,394
- Reward Pool: 25 million HKO
- Crowdloan Cap: 400,000 KSM
Heiko offers dynamic rewards based on total participation:
Reward per KSM = Total HKO Pool / Total KSM Contributed
At maximum cap, each KSM yields at least 62.5 HKO. Rewards are released linearly over one year after Heiko successfully deploys on Kusama.
Basilisk (HydraDX’s Innovation Lab)
- KSM Raised: 33,868
- BSX Reward Pool: 15 billion BSX (15% of supply)
- HDX Compensation: Up to 56.87 million HDX
- Crowdloan Cap: 222,222 KSM
Basilisk introduces a time-sensitive reward multiplier:
- Maximum multiplier (1x) applies within the first 45 hours.
- During the candle phase (final 5 days), it linearly drops to 0x.
Early contributors earn more. For example:
- A contributor who joins early with a 1% share could receive up to 150 million BSX.
- Delaying until midway through reduces rewards by half.
Additionally, contributors receive HDX tokens to offset opportunity costs from locked KSM. The compensation rate varies from 5% to 30%, depending on Basilisk’s competitiveness during the auction.
Altair (Centrifuge on Kusama)
- KSM Raised: 30,933
- Reward Rate: 400 AIR per 1 KSM
- Crowdloan Cap: 200,000 KSM
Altair offers:
- Base reward: 400 AIR per KSM
- Early bird bonus: +10% for contributions within first 48 hours
- Referral bonus: +5% for both parties
- Special surprise rewards for contributions over 10 KSM (details forthcoming)
Rewards are partially vested: 25% upon release, with the remainder distributed linearly over 48 weeks.

Frequently Asked Questions (FAQ)
Q: What is a parachain slot auction?
A: It's a candle-style auction where blockchain projects compete for limited slots on the Kusama relay chain by gathering community support via crowdloans. Winning projects gain access to shared security and cross-chain interoperability.
Q: How do I participate in a crowdloan?
A: You can lock your KSM tokens to support a project through its official crowdloan page on polkadot.js.org. In return, you receive that project’s native tokens as rewards once they launch.
Q: Can I lose my KSM in a crowdloan?
A: No. Your KSM is locked—not lost—and fully returned after the lease period ends (up to ~90 weeks). However, you cannot trade or stake them during this time.
Q: What happens if my supported project doesn’t win?
A: All contributed KSM are safely returned to participants. There is no penalty for backing a losing bid.
Q: When will I receive my reward tokens?
A: Distribution timelines vary by project. Some begin immediately after deployment (e.g., Heiko), while others use vesting schedules (e.g., Altair’s 48-week release).
Q: Why does Kusama use candle auctions?
A: The randomized ending period prevents last-minute "sniping" and encourages fairer bidding behavior by obscuring the exact end time.
