😍 Networks where you can deploy ink! contracts

Production

• Shiden: Kusama parachain by the Astar team, contains the pallet-contracts and thus supports ink! contracts.

Testnets

• Rococo Smart Contracts Parachain: Operated by the developers behind ink! and Substrate's pallet-contracts.
• Shibuya: Testnet parachain by Astar, connected to a custom relaychain also maintained by Astar.
• Phala: Further documentation can be found here.
• Aleph Zero: Support for ink! smart contracts on their testnet.
• peaq network: ink! smart contracts are live on their testnet.
• t3rn: Their testnet is called t0rn, the faucet can be found here.
• Pendulum: The testnet is called Foucoco, there is no faucet currently.

🏆 DApps

• Prosopo: Human verification on the blockchain, has a dapp example which is written in ink!: https://github.com/prosopo-io/dapp-example
• Showcase dApps: Collection of production ready dApps (contracts + UI) ‒ Uniswap v2, Farming, NFT, …
• INK!athon - Full-stack dApp boilerplate with ink! smart contracts and a React frontend using the useInkathon hooks library maintained by Scio Labs.

🛠️ Libraries & Standards

• OpenBrush: OpenBrush is a library for smart contract development with ink!.
• PSP-22: Fungible Token Standard for Substrate's contracts pallet.
• py-substrate-interface: Library by Polkascan to interact with ink! contracts from Python.
• hashes: Collection of cryptographic hash functions written in pure Rust. (no_std needs to be enabled).
• data-encoding: Efficient and customizable data-encoding functions in Rust. (no_std needs to be enabled).
• useInkathon - Typesafe React Hooks library abstracting functionality by polkadot.js for working with Substrate-based networks and ink! smart contracts maintained by Scio Labs.
