Project Overview
GMM is an interdisciplinary initiative combining economics and computer science to create a novel Automated Market Maker (AMM) that eliminates inefficiencies in decentralized exchanges (DEXs). The key innovation is using global blockchain-wide liquidity to compute asset prices, reducing slippage, arbitrage opportunities, and manipulation risks. GMM provides a more stable, transparent, and cost-efficient trading algorithm to underpin a decentralized, tokenized economy.
Methods and approaches
New AMM Design
Based on global, aggregated liquidity data
Mechanism Design
Incentive-compatible rules using microeconomic modeling
Empirical Validation
Historical blockchain data and simulations
Proof-of-Concept Implementation
Based on Uniswap v2 architecture
Social Sciences Integration
45 interviews conducted to guide design and strategy
Open Source Development
Public code, data, and papers
Key Achievements
Novel AMM design that aggregates global liquidity
Formal proof of design properties (e.g., reduced arbitrage)
Simulated and validated GMM with real transaction data
Open-source Proof of Concept (PoC) implementation
Paper accepted at SAET Conference and submitted to TLDR Workshop
Two dissemination blog posts published
Maintained strong EU–US partnership
Defined monetization via consulting services
