Understanding the Fungible Token Standard on Arch Network

Introduction

The Fungible Token Standard program is a crucial piece of infrastructure for the Arch Network ecosystem that enables the creation and management of fungible tokens. Similar to ERC-20 on Ethereum, this standard provides a consistent interface for implementing fungible tokens on Arch Network.

Core Components

Token Mint Details

The foundation of the standard is the TokenMintDetails struct which manages token metadata and supply:
