Hedera Composer Tutorial

Hedera provides a very accessible way for users to connect with and perform transactions on their favorite apps. This comes in the form of Composer, which is a browser extension of Hashing Systems. Composer provides users with a non-custodial crypto wallet from which users can easily manage their HBAR, making transactions, interacting with smart contracts, and buy Hashing Name Service domains, etc.

Note that it is currently available on only Google Chrome.

Composer also gives their developers an easy way to test their dapps on mainnet and testnet. They are making it a smooth experience to develop dapps on Hedera Platform.

You can learn more about how to get started with Composer here

How this improves the extension
