2 • Polkadot’s Relaychain doesn’t support smart contracts by design. • EVM compatibility is everywhere. This is a default feature for Polkadot Parachains. • Platforms are all about “Network E ff ects” but generally there are no fi nancial incentives for early developers to deploy smart contracts.

3 DApp Staking X-VM (Cross Virtual Machine) Layer2 Solution DApp Staking is the system to distribute basic income to developers on Astar Network. By building a product on Astar, developers can earn $ASTA tokens from block rewards based on their performance and decentralized voting. This serves as a strong incentive for developers to choose Astar. Astar supports both EVM and WASM. Solidity, Parity ink! and other WASM   compatible smart contracts can be deployed  on Astar. Smart contracts on EVM can   interact with those on WASM and vice versa. Astar is supporting Plasma and Rollups. Rollups contracts on Ethereum can be used  on Astar as well.

4 “WebAssembly is the future   but legacy EVM is right now.” “You see, the problem with EVM is it’s a hugely opinionated design. It derives from an already very opinionated design, which is the Bitcoin script design,” Wood said. His team wanted to give developers a very non-opinionated format to work with, and that’s WebAssembly . Dr. Gavin Wood, founder of Ethereum and Polkadot.

5 Ethereum Virtual Machine We already support various Ethereum development tools. You can deploy Solidity contracts just like you deploy contracts on Ethereum. Check out our documentation here. Stake Technologies All Rights Reserved

8 Achievements 7 Web3 Grants First Parachains 150K+ ETH 40+ Projects Community Technical Innovations Astar Network’s core team has received 7 grants from Web3 Foundation. (Plasma, Optimistic Virtual Machine, ink! Playground, ZK Rollups, ZK Plonk, ECDSA, ECDSA hardware) Astar Network is the fi rst Polkadot testnet Parachain. Shiden Network, a sister network of Astar, is the third Kusama Parachain TVL through lockdrops. Astar conducted multiple lockdrops  with ETH in 2020 and 2021. More than   150K ETH has been locked in our  smart contracts. Currently, Astar is working with more  than 40 projects (Infrastructure,   DeFi, DAO, NFTs) Especially, Astar is focusing on the NFTs space There are more than 30,000 members  across Telegram, Discord and WeChat. We graduated from the UC Berkeley Xceleration program, Web3 Bootcamp,  and LongHash Acceleration Program. We have deployed the fi rst smart contract on the Polkadot testnet. We have successfully completed the fi rst cross chain message passing (XCMP) on the Polkadot testnet.

9 Reference: Building on Astar Network Astar Network is a Polkadot dApp hub supporting Ethereum Virtual Machine, WebAssembly, and layer2   solutions. Astar Network supports both WASM and EVM. So, developers can deploy Solidity contracts on Astar Network with existing Ethereum tools such as Metamask and Remix. In addition to that, they can also deploy Solidity contracts on WASM with Solang, a Solidity to WASM compiler written in Rust. 1 Ethereum Solidity 2 Parity ink! ink! is an original smart contract language on Substrate made by Parity Technologies. Astar Network supports ink! to build a solid and high performance DApps.
