Introduction
Overview
Hedera Wallet Snap unlocks wallet functionality for Hedera via MetaMask that any other apps can interact with, thereby turning MetaMask into a native Hedera wallet without relying on Hedera JSON-RPC Relay.
With Hedera Wallet Snap, users can send HBAR to another HBAR account id and an EVM address, retrieve account info from either the Hedera Ledger node or Hedera Mirror node.
What is a Snap?
Metamask Snaps is an open source system that allows anyone to safely extend the functioanlity of Metamask, creating new web3 end user experiences. A Snap can add new API methods to MetaMask, add support for different blockchain protocols, or modify existing functionalities using the Snaps JSON-RPC API.
Snaps enable users to interact with new blockchains, protocols, and decentralized applications (dApps) beyond what is natively supported by MetaMask. The goal of the MetaMask Snaps system is to create a more open, customizable, and extensible wallet experience for users, while fostering innovation and collaboration within the blockchain and decentralized application ecosystem.
Developers can write MetaMask Snaps using JavaScript, making it accessible and convenient for a broad range of developers to create custom solutions. Users can then opt to install these snaps to enhance their MetaMask experience, provided they trust the source of the snap.
