Astar
Astar is a Polkadot parachain that supports both EVM and WebAssembly (Wasm) smart contracts, and it acts as a multi-VM hub for the Polkadot ecosystem. Its dApp staking mechanism lets token holders stake ASTR to specific dApps, which gives developers a passive income stream. ArthSwap is the flagship DEX, and Astar focuses on connecting Japanese Web3 companies to Polkadot.
