Background
On June 15, 2021, Polkadot's canary network Kusama hosted its first parachain slot auction. After five months of operational research with Kusama parachains, we've now reached Polkadot's pivotal moment - the parachain slot auctions.
In October 2021, Motion 118 to enable parachain auctions on Polkadot was approved by the Polkadot Council. Starting November 11, 2021, the first Polkadot parachain slot auctions commenced. This historic milestone marks the end of Polkadot's exploration phase, bringing Web3.0 closer to reality as Polkadot's vision of "interconnected chains" accelerates.
For ecosystem projects, connecting to Polkadot's innovative mainnet provides shared security, interoperability, access to a vibrant community, and billions in liquidity. The parachain slot auctions have been highly anticipated, though some mystery remains for participants. This guide aims to demystify the process.
Parachain Slot Auction Rules
Building on Kusama's precedent, Polkadot's parachain slot auction rules are more intuitive:
Auction Rounds:
First Round: 5 auctions total
- Starts November 11, 2021
- Each auction lasts 7 days
- New auction starts every 7 days
- Lease Periods: Lease 6 to Lease 13 (Lease 6 begins December 15)
Second Round: 6 auctions total
- Starts December 23, 2021
- Each auction lasts 7 days
- New auction starts every 14 days
- Lease Periods: Lease 7 to Lease 14 (Lease 7 begins March 9, 2022)
Each 7-day auction has:
- 2-day initial bidding period
- 5-day randomized ending (candle period)

Key Differences Between Polkadot and Kusama Auctions
While Kusama served as Polkadot's testnet, several crucial differences exist:
1. Lease Periods
- Polkadot: Each slot lasts 2 years (96 weeks), divided into 8 lease periods of 3 months each
- Kusama: 8 lease periods of 6 weeks each (total 1 year max)
2. Project Participation
- Some projects participate exclusively on Polkadot or Kusama
- Incentive structures differ between networks
- Teams may adjust strategies based on Kusama experience
3. Market Response
- Polkadot auctions attract more attention and participation
- Exchange support is more extensive (Binance, OKEx, etc.)
- Crowdloan rewards are better understood after Kusama experience
Parachain Slot Auction Strategies
1. Reward Calculations
- Compare potential Crowdloan rewards against staking yields
- Consider linear release schedules (vs immediate rewards)
- Factor in liquidity solutions (e.g., lcDOT)
2. Project Selection
- Short-term focus: High visibility projects with early rewards
- Long-term focus: Projects with strong fundamentals and growth potential
- Evaluate team, funding, tokenomics, and roadmap
3. Optimal Timing
- First 2 days of initial auctions are most critical
- Monitor leaderboard positions before committing
- Consider early-bird incentives
