# Contract Modifications

### Licensing[​](https://docs.uniswap.org/contracts/v3/guides/governance/liscense-modifications#licensing) <a href="#licensing" id="licensing"></a>

Please note that the SYMM Core is under BUSL license until the Change Date, \
currently 12-31-2027. \
\
Exceptions to the license may be specified by SYMM Governance via [Additional Use Grants](/legal-and-brand/terms-of-service-and-licensing/contract-license/contract-use-grants.md), which can, for example, allow the CORE to be deployed on new chains or be released in partnership with new Frontends.&#x20;

The process to request a DAO vote for exceptions to the license or move up the Change Date will be released soon.

Modifications of the Change Date should be specified at [Contract Modifications](/legal-and-brand/terms-of-service-and-licensing/contract-license/contract-modifications.md), and Additional Use Grants should be specified at [Contract Use Grants](/legal-and-brand/terms-of-service-and-licensing/contract-license/contract-use-grants.md).&#x20;
