DeFiaccessiblethroughPython
From data-sourcing over backtesting strategies to analytics — we cover your infrastructure needs in one simple Python package. No Solidity required.

Python Interface
A Python interface for DeFi, enabling users to build and simulate strategies and contracts entirely on-premises before real-world deployment.
Data accessibility
Access on-chain data of any smart contract and any historic block for data ingestion and strategy evaluation.

Python Interface
A Python interface for DeFi. You don't need to run a node. No data-sourcing required. Only Python.
Simulation platform
Test and train strategies and smart contracts through dojo’s agent-based simulator to simulate transactions at the EVM smart contract level.
