Licensing issue - ExchangeMonthlyLimitsModule.sol

Nethermind is working to provide an implementation of ERC-3643 Asset Tokenization standard for Starknet. It will include translation of existing Solidity implementation into Cairo smart contract suite.

Our translation would include the following smart contract:

Issue

The above smart contract seems to have been dual licensed under GPLv3 and CC-BY-NC-4.0.

The GPLv3 element of the license does not create problems - the other smart contracts in the ERC-3643 Solidity implementation are similarly licensed under GPLv3, and this was therefore the intended license for the Cairo implementation in any case.

However, the CC-BY-NC-4.0 license restricts commercial use and may therefore severely limit the utility of our implementation.

---

Importantly GPLv3 specifically grants users the freedom to run, copy, distribute, study, change and improve the software for any purpose, including commercial purposes. The CC-BY-NC-4.0 license, with its "non-commercial" restriction, directly conflicts with this freedom.

Was this dual licensing an accident?

Hi @Icedcool The reference implementation for ERC-3643 has been moved to https://github.com/ERC-3643/ERC-3643
The T-REX repository is deprecated and will soon be archived. The modules of compliance are not part of what tokeny open sourced, at least not for now. But the abstract module contract and the general approach are open source, so you can build your own modules without breaking any license
