simular

Simular is a Python API you can use to deploy and interact with Ethereum smart contracts and an embedded Ethereum Virtual Machine (EVM). It creates a Python wrapper around production grade Rust based Ethereum APIs making it very fast.

How is it different than Brownie, Ganache, Anvil?

• It’s only an EVM. It doesn’t include blocks and mining

• No HTTP/JSON-RPC. You talk directly to the EVM (and it’s fast)

• Full functionality: account transfers, contract interaction, and more.

The primary motivation for this work is to be able to model smart contract interaction in an Agent Based Modeling environment like Mesa.

Features

• Run a local version with an in-memory database. Or copy (fork) state from a remote node.

• Parse Solidity ABI json files or define a specific set of functions using human-readable notation.

• Dump the current state of the EVM to json for future use in pre-populating EVM storage.

• User-friendy Python API

Standing on the shoulders of giants…
