  1. Introduction

What tools are this toolkit made of?

The Jungle Toolkit is created using a large number of amazing tools and technologies. Our goal is to connect libraries, SDK & blockchains, both from the EVM & DOT worlds.

Wallets:

  • MetaMask: the most popular EVM wallet. Polkadot accessible through the use of Snap

  • Talisman: the recommended wallet at the Polkadot Blockchain Academy

  • SubWallet: a really great option of the ecosystem

APIs

  • LightSpell: an amazing API greatly facilitating XCM interoperability

  • Squid API: a convenient way to generate routes and calls between EVM-compatible chains

SDKs

  • Squid SDK V2: an Axelar-based project that allows easy cross-chain swaps integration

  • Moonbeam XCM SDK: very useful to calculate complexe cross-chain fees

  • ParaSpell SDK: generating valid XCM calls in a convenient and easy way

Libraries

  • @ethers: the most-used JS library to interact with EVM-compatible chains

  • @polkadot/api: a great wrapper to interact with Substrate-based chains

Smart Contracts

  • Squid Router

  • Uniswap V2/V3 pools interface

  • Moonbeam CallPermit Precompile

  • Moonbeam Batch Precompile

  • Moonbeam Transactor V3

Others

  • Vanilla JavaScript

  • Node.js V18

  • Solidity >= V8.2
