Smart Contract Standard Atributos
Permissions Permissioned by parachain governance; open deployment on parachains that enable pallet-contracts; deposit required per contract
Development Tools 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)
Protocol Maturity / Standardization Mature for its ecosystem; reached ink! 5.x before discontinuation; never achieved broad adoption comparable to Solidity or CosmWasm
Trust Framework Substrate runtime-level trust; contract owner patterns; no built-in reputation layer; pallet-contracts enforces storage deposit as spam prevention
Target Application Domain DeFi on Polkadot parachains, cross-parachain dApps, gaming, NFTs (PSP-34 standard), DAO tooling — all now in question following discontinuation
Deployment Model Per-contract Wasm blob stored on-chain; re-instantiation from same code hash; storage deposit model
Standard Type Composability Standard (smart contract language / framework)
Ecosystem Polkadot
