Parachain auctions are a core feature of the Polkadot and Kusama ecosystems, allowing projects to secure a slot and connect to the network's shared security. For users, these auctions present an opportunity to support promising projects and earn rewards by locking their tokens. This guide provides a clear overview of how these auctions work and the various ways you can participate.
Understanding Polkadot and Kusama Parachain Auctions
The Polkadot network is designed with a central Relay Chain and multiple parallel chains, or parachains. Since parachain slots are a limited resource, they are allocated through a periodic candle auction process. Kusama, Polkadot’s canary network, hosts its own auctions for projects that wish to test in a real, economic environment first.
In a parachain auction, projects crowdloan DOT or KSM tokens from the community. Users who contribute their tokens to a project’s bid are effectively locking them up for the duration of the parachain lease. If the project wins the auction, contributors are rewarded with the project’s native tokens. If the bid fails, the locked DOT or KSM is returned to the contributors.
How to Participate in an Auction
Participating in a parachain auction involves committing your tokens to a project's crowdloan campaign. The process is designed to be straightforward, whether you choose to participate directly on-chain or through a third-party service.
1. Locking Your Tokens
You can participate by buying or transferring KSM/DOT to a supporting platform and locking them for a specific project's auction bid. This action demonstrates your support for that project’s proposal.
2. The Bidding Process
The auction occurs on-chain. It's important to monitor the results. If the project you backed does not secure a slot, your locked KSM/DOT funds will be returned to you in full, without any interest accrued.
3. Earning Rewards
If your chosen project wins the auction, you will receive rewards. These are typically distributed based on the annual percentage rate (APR) determined by the project on-chain. Once the locked chain-based KSM/DOT funds are released, users receive their initial contribution plus any rewards directly. You can explore more strategies for evaluating different project rewards.
Key Rules and Considerations
Before you decide to participate, it’s crucial to understand the basic rules and potential implications.
- Tokens Used: The primary currencies for these auctions are KSM (for Kusama) and DOT (for Polkadot).
- Fees: Some platforms offer participation with no service fees.
- Interest Rate: The annual interest rate for rewards is set on-chain by each individual project and can vary significantly.
- Successful Auction: If your supported project wins, rewards are distributed according to the project's specified on-chain APR.
- Early Unlocking: The locked funds are typically committed for the entire lease duration (often 48-96 weeks). Early unlocking is usually not an option until the lease period concludes.
- Failed Auction: If the project's bid is unsuccessful, your entire locked amount is returned to you without any penalties.
It is important to remember that while many platforms provide a user-friendly service for participation, they act as intermediaries. They are not liable for any losses that may occur due to project-related issues or on-chain security problems. Always conduct thorough research on any project before locking your funds.
Frequently Asked Questions
What are Polkadot parachain auctions?
Polkadot parachain auctions are events where projects bid to secure a leased slot on the Polkadot Relay Chain. They gather DOT tokens from the community through crowdloans to back their bid. Supporters are rewarded with the project's tokens if the bid is successful.
How do I claim my rewards from a parachain auction?
If you participate through a major exchange or custodial service, rewards are typically distributed automatically to your account on that platform once the project issues them. If you contribute directly on-chain, you will need to claim your rewards through the project’s designated interface or the parachain’s dashboard.
Can I lose my DOT or KSM tokens by participating?
Your initial contribution is not sold or spent; it is locked for the duration of the parachain lease. The primary risk is opportunity cost—your tokens are illiquid during the lock-up period. The main financial risk is that the value of the reward tokens you receive could fluctuate.
What is the difference between Polkadot and Kusama auctions?
Kusama is Polkadot’s faster-paced, experimental “canary network.” Kusama auctions often feature newer, riskier projects and have shorter lease periods. Polkadot auctions are generally for more established projects and involve longer commitment periods.
Is there a minimum amount required to participate?
The minimum contribution amount depends on the platform you use. Some exchanges allow for very small contributions, while direct on-chain participation may have a higher minimum due to transaction fees and technical requirements.
What happens if a project wins a slot but fails later?
Winning a slot does not guarantee a project's success. If a project fails after deploying its parachain, the tokens you contributed are still locked for the entire lease duration and will only be returned at the end of the term. Your reward tokens may also lose value. This highlights the importance of careful project due diligence.
