ink! is a Rust-based eDSL (embedded Domain-Specific Language) developed by Parity Technologies for writing smart contracts on Substrate's pallet-contracts.

💡 Why ink!? ink! is currently the most widely supported eDSL for Substrate-based smart contracts, with strong backing from both Parity and the builder community.

Key Features

ink! provides developers with powerful tools and features:

Core Capabilities

• Leverage ink! macros and attributes via #[ink::contract]

• Utilize trait definitions and implementations

• Create upgradeable contracts through delegate calls

• Interact with Substrate pallets using Chain Extensions

• Perform off-chain testing with #[ink(test)]
