Astar is a multi-chain smart contract platform on Polkadot, supporting both Ethereum Virtual Machine (EVM) and WebAssembly (Wasm) environments. Its native token, ASTR, is used for transaction fees, staking, and governance within the network.

Tangle Network's integration with Astar Network enables staking Astar tokens (ASTR) in exchange for tgASTR minted on Tangle Parachain, enabling participation in decentralized applications and services while enhancing staking rewards.
