twasm-utils

A collection of WASM utilities used in twasm-vapory and tetcore contract development.

This repository contains the package twasm-utils which consists of a library crate and a collection of cli binaries that make use of this library.

Installation of cli tools

cargo install twasm-utils --features cli

This will install the following binaries:

• wasm-build
• wasm-check
• wasm-ext
• wasm-gas
• wasm-pack
• wasm-prune
• wasm-stack-height

Symbols pruning (wasm-prune)

wasm-prune <input_wasm_binary.wasm> <output_wasm_binary.wasm>

This will optimize WASM symbols tree to leave only those elements that are used by contract call function entry.

Gas counter (wasm-gas)

For development puposes, raw WASM contract can be injected with gas counters (the same way as it done by twasm-vapory/tetcore runtime when running contracts)

wasm-gas <input_wasm_binary.wasm> <output_wasm_binary.wasm>
