# Welcome to Dedot

Dedot is the next-generation JavaScript client for [Polkadot](https://polkadot.com) and [Polkadot SDK-based](https://polkadot.com/platform/sdk/) networks.

Designed to elevate the dapp development experience, Dedot is built & optimized to be lightweight and tree-shakable, offering precise Types & APIs suggestions for individual Polkadot SDK-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)
* Typesafe APIs for [on-chain interactions](https://docs.dedot.dev/client-api) & [smart contracts](https://docs.dedot.dev/ink-smart-contracts)
* Build on top of both the [new](https://paritytech.github.io/json-rpc-interface-spec/introduction.html) & [legacy](https://github.com/w3f/PSPs/blob/master/PSPs/drafts/psp-6.md) (\*deprecated soon) JSON-RPC APIs
* Support light clients (e.g: [smoldot](https://github.com/smol-dot/smoldot))
* Using native TypeScript type system for [scale-codec](https://docs.substrate.io/reference/scale-codec/)
* Compatible with [`@polkadot/extension`](https://github.com/polkadot-js/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, V16 (latest)
* Metadata optimization (caching, compact mode 🔜)
* ... and a lot more 🔜
