  1. Crownloan participants vote for projects by reserving their free KSM tokens
  2. Voting is handled by the native Crowdloan module on Kusama, there’s no need to send your tokens anywhere.
  3. Every parachain candidate will have its own index for the crowdloan.
  4. To vote with your KSM tokens you must send a special transaction with an index of the project you want to help win a slot
  5. The module will take your tokens and lock them in its vault. Your tokens have to be available for transfer, not staked or vested.
  6. If the project that you support wins the auction, your KSM tokens are locked for one year, until the slot leasing period is over. When it’s over, your tokens will be automatically returned to your address. If the project fails to get a slot, you get your tokens immediately.
  7. In return for such a long lockup period, you will get various rewards from the projects that you vote for. Usually, you get rewarded with tokens.
  8. If you use someone’s referral link, both you and the person that provided you with the link receive an additional token bonus, so be sure to use a link. We have provided our referral links in the text though.
  9. The first auction will be conducted from June 15th, 2021 to June 22nd, 2021. There will be 5 slot auctions, one per week. The last one will end on July 20th, 2021.
  10. The exact moment of the auction’s close is determined randomly and retroactively, thus the sooner you allocate the tokens, the better. Otherwise, the VRF module (verifiable random function) may not count your stake at all if you do it late.


  1. A trustless staking derivative, liquid KSM. The underlying HOMA protocol allows users to join a special staking pool, stake their KSM tokens to gain staking yield and get L-KSM to stay liquid. These L-KSM tokens can be used anywhere across all Kusama-connected chains and can be redeemed anytime for KSM. They can even be used as collateral or as fee tokens.
  2. A stablecoin kUSD. It’s based on the Honzon protocol, it’s very similar to MakerDAO and the way how it handles assets. Assets are locked in a CDP (Collateralized Debt Positions) upon a user’s request, after locking them the protocol mints new kUSD tokens. An automatic risk management algorithm checks CDPs all the time to make sure that the value of the collateral is bigger than the value of minted kUSD. The protocol accepts many types of tokens, including almost all tokens of the Kusama ecosystem and even BTC and ETH via bridges.
  3. A DEX with an Automated Market Maker.


  1. Supports both Ethereum Virtual Machine (EVM), native to Ethereum, and Web Assembly Machine (WASM), native to Substrate
  2. One of its core features, the X-VM (Cross Virtual Machine), creates a layer of abstraction that allows smart contracts to execute calls and read storage data from different contract engines (virtual machines) and languages within the same blockchain.
  3. Allows to write contracts in Solidity, ink!, Rust, C/C++, C#, Typescript, Haxe, and Kotlin.
  4. Natively supports Metamask and Remix.
  5. 50% of its network fees go to reward developers of dapps, the more popular the dapp is, the more its developer gers.
  6. It’s possible to change the dapp owner address in Shiden after deploying the contract..
  7. They will have an Ethereum bridge implemented in the near future,
  8. Optimistic Virtual Machine allowing dapp developers to use such Layer 2 protocols as Rollups. zkRollups are fully supported right now, more protocols to come.
  9. Already has a cross-chain DEX KwikSwap running on top of Shiden.


  1. Supports all Ethereum smart contracts written in Solidity and Vyper.
  2. It’s compatible with all Ethereum tools, such as MetaMask, Truffle and Remix.
  3. Supports Ethereum libraries such as Ethers.js, so any developer can work with a Moonriver node as if it was an Ethereum node. Also, it supports Web3 Python and Javascript libraries allowing to use IPC, HTTP, or WebSocket protocols the same way as Ethereum developers do.
  4. Cross-chain ERC20 token transactions. Moonriver can connect to Ethereum via the Kusama bridge and via ChainBridge and transfer tokens back and forth.
  5. Built-in integrations for oracles, such as ChainLink, Razor Network and Band Protocol.
  6. At the same time, it’s still a Substrate-based blockchain and it’s fully compatible with the whole Substrate toolset including block explorers, front-end development libraries, and wallets.
