Introduction

The x/gamm module implements the Generalized Automated Market Maker (GAMM) functionality for the BitBadges blockchain. This module was forked from Osmosis's x/gamm module and provides the core infrastructure for decentralized exchange (DEX) operations, including liquidity pool creation, token swaps, and yield farming.

Fork from Osmosis

This module maintains compatibility with Osmosis's GAMM functionality while adding specialized support for BitBadges tokens. The key modifications include:

• Interface Simplification: Removed unused parameters and streamlined type definitions

• Badge Token Support: Integrated native badge token handling with automatic conversion

• Enhanced Compatibility: Ensures seamless operation with existing DeFi infrastructure

Key Concepts

Automated Market Maker (AMM)

An AMM is a decentralized exchange protocol that uses mathematical formulas to determine token prices and facilitate trades without the need for traditional orderbooks.

Liquidity Pools

Liquidity pools are smart contracts that hold pairs of tokens and allow users to trade between them. Each pool has:

• Pool Assets: The tokens held in the pool

• Pool Shares: LP tokens representing ownership of the pool

• Swap Fee: Fee charged on each trade

• Exit Fee: Fee charged when exiting the pool

Pool Types

The GAMM module currently supports:

• Balancer Pools: Standard AMM pools with configurable weights
