wasm-utils
Collection of WASM utilities used in pwasm-ethereum and substrate contract development
Build tools for cargo
Easiest way to use is to install via cargo install:
cargo install pwasm-utils-cli --bin wasm-build
Symbols pruning (wasm-prune)
cargo install pwasm-utils-cli --bin 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 pwasm-ethereum/substrate runtime when running contracts)
cargo install pwasm-utils-cli --bin wasm-gas
wasm-gas <input_wasm_binary.wasm> <output_wasm_binary.wasm>
API
All executables use corresponding api methods of the root crate and can be combined in other build tools.
