Acala's sister and the DeFi Hub of Kusama.
Karura is an all-in-one decentralized finance (DeFi) hub and stablecoin platform built on Kusama (KSM) and integrated into Polkadot (DOT). Karura and Acala operate in parallel. Specifically, Karura is implementing DeFi on Kusama in the same way that Acala is offering DeFi on Polkadot. It 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 (aUSD), and an AMM DEX – all with micro gas fees that can be paid in any token.
