Develop, Backtest, and
Execute in DeFi with Ease.
Execute in DeFi with Ease.
Our technology lays the foundation for a new paradigm in digital assets: from data-sourcing and strategy development over backtesting and simulation to analytics — we cover your DeFi infrastructure needs in one simple Python package. No Solidity required.
Introducing Dojo
An institutional-grade DeFi platform that seamlessly integrates with your trading workflow, empowering users with instant, on-premise connectivity to DeFi.
What does Dojo offer?
Protocol Integration
Bridging the gap. A unified interface for DeFi interoperability across protocols and chains.
Dojo offers a unified Python interface to the most liquid spot, lending and derivatives exchanges, enabling users with instant connectivity from a single platform. Dojo is successfully integrated with Uniswap, Aave and soon GMX.
Data accessibility
Decipher history. Access to detailed DeFi data across multiple blockchain networks.
Curated and fast access to tick-level on-chain data in standardized data formats, including event and function call data for any contract since network inception. Versatile delivery in your preferred format.
Python Interface
Smart contracts, simplified. Develop strategies in pure Python.
Seamlessly access DeFi with simple Python functions like aave_flashloan or uniswap_trade. Run arbitrary Python code, make API calls, and incorporate external data feeds, leveraging the full power of Python's ecosystem. No need to run a node or manage data pipelines — everything you need is readily available and easy to use.
