Welcome to Dedot

Dedot is the next-generation JavaScript client for Polkadot and Substrate-based blockchains.

Designed to elevate the dapp development experience, Dedot is built & optimized to be lightweight and tree-shakable, offering precise Types & APIs suggestions for individual Substrate-based blockchains and ink! Smart Contracts. Dedot also helps dapps efficiently connect to multiple chains simultaneously as we head toward a seamless multi-chain future.

Features

• Small bundle size, tree-shakable (no more bn.js or wasm blob)

• Fully-typed APIs for on-chain interactions & ink! smart contract

• Build on top of both the new & legacy (*deprecated soon) JSON-RPC APIs

• Support light clients (e.g: smoldot)

• Using native TypeScript type system for scale-codec

• Compatible with @polkadot/extension-based wallets (SubWallet, Talisman...)

• Fully-typed low-level JSON-RPC client for advanced usage

• Similar API-style with @polkadot/api, easy and fast migration

• Support Metadata V14, V15 (latest)

• Metadata optimization (caching, compact mode 🔜)

• ... and a lot more 🔜
