Acala is the decentralized finance (DeFi) and liquidity hub of the Polkadot ecosystem, operating the Acala parachain (and its Kusama-based sister network Karura). Acala offers a scalable, Ethereum-compatible smart-contract platform called Acala EVM+, a decentralized stablecoin (aUSD), a liquid staking derivative (LDOT/LcDOT), and a trustless staking and swap layer. For developers, Acala EVM+ exposes a standard Ethereum JSON-RPC interface through its EVM+ RPC Adapter (eth-rpc-adapter), letting existing Ethereum dApps, wallets (MetaMask), and tooling (Hardhat, Remix, ethers.js, Truffle) interact with the Substrate-based chain with minimal changes, alongside a Substrate WebSocket RPC via the @acala-network Polkadot.js API and SDK packages.
