# wasi2ic
[](https://codecov.io/gh/wasm-forge/wasi2ic)
`wasi2ic` is a tool to convert WebAssembly System Interface (WASI) dependent Wasm module to run on the Internet Computer (IC) computer.
## Compiling wasi2ic
* Clone the https://github.com/wasm-forge/wasi2ic:
```bash
git clone https://github.com/wasm-forge/wasi2ic
```
* Enter the `wasi2ic` folder
* Compile the project with `cargo build` and copy the tool to some executable path or alternatively use `cargo install --path .`, but note that the project is still in the early development.
## Usage
To use this tool, navigate to the directory where the WASI-dependent project resides, and run the command:
```bash
wasi2ic
```
This will read the old Wasm file and create a new Wasm file with the WASI dependencies removed.
**NOTE**
The tool requires that the polyfill implementation is present in your Wasm binary, to include the polyfill implementation into your canister project you need to add the dependency:
```bash
cargo add --git https://github.com/wasm-forge/ic-wasi-polyfill
```
This will create the polyfill methods in your `.wasm` file, which are needed for `wasi2ic`.
Also add the call to the init of the polyfill, example:
```rust
#[ic_cdk::init]
fn init() {
unsafe {
ic_wasi_polyfill::init(&[0u8; 32], &[]);
}
}
```
**NOTE2**
The polyfill library is still in early development, and not all methods are implemented. Feel free to review its current state before use.
