EVM Toolkit

The "EVM Toolkit" (ETK) is a set of tools designed for creating and analyzing smart contracts on the Ethereum Virtual Machine. It includes an assembler (eas) for creating contracts and a disassembler (disease) for studying them. ETK is new and experimental, offering a fresh approach to smart contract development. With its innovative tools, ETK aims to simplify the process of working with the Ethereum Virtual Machine, although its experimental nature suggests cautious exploration.

Tools Offered by EVM Toolkit

1. Assembler: eas

The assembler resides within the etk-asm crate, offering both a command-line interface (eas) and a Rust library. Noteworthy for its capabilities, the assembler boasts several distinguishing features:

• Enhanced Scope Management: It supports importing multiple files into a unified scope, facilitating organized development.

• Constructive Isolation: For constructors and initialization code, files can be included in a distinct scope, streamlining code organization

• Effortless Push Size Selection: The assembler intuitively selects push sizes, reducing manual intervention for optimal efficiency

• Solidity-Inspired Function Selectors: Employing Solidity-style function selectors, the assembler aligns with industry standards, fostering familiarity and ease of use.

Invoking the assembler is pretty simple:

eas input.etk output.hex

A Note to Path:The input argument determines the root of the project. If /home/user/foobar/main.etk is the input argument, the root would be /home/user/foobar. Only files within the root directory can be included or imported.

2. Disassembler: disease

The disassembler is housed within the etk-dasm crate, offering both a command-line interface (disease) and a Rust library. The disassembler, while more exploratory in nature, showcases a specific set of functionalities:

• 1. Effortless Code Deciphering: It can transform hex or binary encoded instructions into their corresponding mnemonics, simplifying the understanding of complex code sequences.

• 2. Basic Block Detection: The disassembler excels in identifying fundamental code blocks, contributing to code analysis and comprehension.

The basic invocation of disease looks like:

disease --bin-file contract.bin         # Disassemble a binary file
disease --hex-file contract.hex         # Disassemble a hexadecimal file
disease --code 0x5b600056               # Disassemble the command line argument
