@vking45 thanks for wanting to contribute to the library 🚀 Of course you can work on this issue!
It would be great if you can submit a draft PR with your initial design/implementation, that way our team can give you feedback early on.

@bidzyyys created a draft PR with just safe_transfer implemented to show what is the idea for the utility's design, let me know if you have any feedback and if you think I can continue working on this.

Note that the documentation within the PR is copy/pasted from the Solidity version, it's low priority atm and is still wip
