Gauntlet is the financial modeling and simulation platform for blockchains.
Decentralized systems create new challenges for protocol developers, smart contract developers, and asset holders that you don’t see in traditional development and asset management. Gauntlet uses tried and tested techniques from algorithmic trading to simulate crypto networks, inform design decisions, and drive successful design and participation.
