 ## Dependencies

-- [Leap](https://github.com/AntelopeIO/leap) 4.0 or later
-  + Currently there is an issue in the 4.0 release of Leap that causes test to fail to build with C++20 (which is necessary due to the silkworm dependency of the erc20 contract).
-  + To work around this issue, one option is to build Leap from the main branch of the [leap](https://github.com/AntelopeIO/leap) repo which has changes to support building Leap with C++20.
-  + An alternative workaround for this issue is to apply the fix mentioned in https://github.com/AntelopeIO/leap/issues/1497 to a copy of the [release/4.0](https://github.com/AntelopeIO/leap/tree/release/4.0) branch before building Leap. The branch [4.0-with-evm-fix](https://github.com/AntelopeIO/leap/tree/4.0-with-evm-fix) is also available with the fix already applied to a recent copy of the release/4.0 branch.
