About KAR
Website丨Explorer | Whitepaper

Karura is the all-in-one DeFi hub of Kusama.Founded by the Acala Foundation, Karura is a scalable, EVM-compatible network optimized for DeFi. The platform offers a suite of financial applications including: a trustless staking derivative (liquid KSM), a multi-collateralized stablecoin backed by cross-chain assets (kUSD), and an AMM DEX – all with micro gas fees that can be paid in any token.

Kusama is Polkadot’s faster, wilder cousin – a multi-chain network for radical innovation.

Kusama and Polkadot are independent, standalone networks built in nearly the exact same way, but Kusama has faster governance parameters and higher risk tolerance.

By launching on Kusama, Karura can push the limits of what’s possible, giving the Acala Foundation team a place to launch bold new financial innovations. Karura will access Kusama’s plug-and-play security while enjoying high-capacity processing speeds, micro-gas fees, and interoperability between multiple networks, all ultimately bridged to Polkadot.

Karura will deliver decentralized financial products and stable assets to Kusama’s entire ecosystem of networks.

KAR is a utility token with a fixed supply of 100,000,000. The entire supply will be minted in the genesis block at launch. KAR will be rewarded to participants who support the Parachain Auction with KSM. Upon receipt, 30% of this KAR will be unlocked and transferable, while the remaining 70% will be vested and released gradually over 48 weeks.

Karura token(KAR) utility:

Transaction Fees: Powers the micro gas fees and smart contract execution.
Node Incentivisation:Incentivizes network nodes to monitor and relay messages to Kusama.
Governance:Empowers the community to vote, elect council members, and drive the development of Karura.
Algorithmic Risk Adjustment:Auto-adjusts risk parameters such as interest rates or collateral ratio.
Pallet Deployment:Allows teams to deploy new Substrate pallets on the Karura blockchain by staking KAR.
Smart Contract Deployment:Enables teams to deploy new DApps and smart contracts on Karura’s platform after staking KAR.

What is Automated Market Making (AMM)?
Automated market making (AMM) can calculate the buying and selling price according to the formula, so as to provide a continuous quotation for the market. CoinEx combines AMM with the order book, which means the liquidity pool will be automatically converted into the order book. With the "constant product market maker formula" algorithm in AMM, no matter how large the order book is or how small the liquidity pool is, firm liquidity provision to the market can be guaranteed.
