 1. [`solc`](https://solidity.readthedocs.io/en/latest/installing-solidity.html). We also recommend using [solc-select](https://github.com/crytic/solc-select) for more flexibility.

-## Known limitations
-
-Currently, due to an issue in our upstream (https://github.com/wasmerio/wasmer/issues/4072), this crate works as expected only up to Rust version `1.67.0`; in newer Rust versions, `wasmer` is currently unsound.

 ## Acknowledgements
 
 This library would not have been possibly without the great work done in:

 - [`zkutil`](https://github.com/poma/zkutil/)
 - [`snarkjs`](https://github.com/iden3/snarkjs/)
