Do refer to the contribution guidelines for more details.
This is experimental software and is provided on an "as is" and "as available" basis.
We do not give any warranties and will not be liable for any loss incurred through any use of this codebase.
While Solady has been heavily tested, there may be parts that may exhibit unexpected emergent behavior when used with other code, or may break in future Solidity versions.
Please always include your own thorough tests when using Solady to make sure it works correctly with your code.
All contracts in Solady are compatible with both upgradeable and non-upgradeable (i.e. regular) contracts.
Please call any required internal initialization methods accordingly.
Some parts of Solady may not be compatible with chains with partial EVM equivalence.
Please always check and test for compatibility accordingly.
