Padrão de Contrato Inteligente Atributos

Origens Created by Parity Technologies alongside Substrate as the native smart contract language for Polkadot parachains; designed to provide Rust's correctness guarantees for Wasm-based contracts, avoiding Solidity's pitfalls; Polkadot's pivot to EVM compatibility in 2025-2026 redirected resources away from ink!
Formatos de Dados Rust structs and enums for contract storage and messages; Borsh serialization for scale-encoded data; JSON for metadata; SCALE codec for on-chain encoding
Termos Apache 2.0
Fundos Unknown; Parity internal R&D budget; no discrete public figure; Polkadot Treasury inkubator funded select projects using ink!
Baseado Em Substrate pallet-contracts (runtime environment); influenced by Solidity design but Rust-native; ERC-20/ERC-721 concepts ported as CW-style patterns
Permissões Permissioned by parachain governance; open deployment on parachains that enable pallet-contracts; deposit required per contract
Ferramentas de Desenvolvimento cargo-contract (build, test, deploy CLI); drink! (lightweight local testing); DRink! (TUI-based chainless dev tool); rust-analyzer and Clippy (native Rust tooling); Contracts UI (browser-based deployment)
Maturidade / Padronização do Protocolo Mature for its ecosystem; reached ink! 5.x before discontinuation; never achieved broad adoption comparable to Solidity or CosmWasm
Estrutura de Confiança Substrate runtime-level trust; contract owner patterns; no built-in reputation layer; pallet-contracts enforces storage deposit as spam prevention
Domínio de Aplicação-Alvo DeFi on Polkadot parachains, cross-parachain dApps, gaming, NFTs (PSP-34 standard), DAO tooling — all now in question following discontinuation
Modelo de Implantação Per-contract Wasm blob stored on-chain; re-instantiation from same code hash; storage deposit model
Tipo de Padrão Composability Standard (smart contract language / framework)
Ecossistema Polkadot
