Distributes all outstanding reserved tokens for a project.
Definition
function _distributeReservedTokensOf(uint256 _projectId, string memory _memo)
internal
returns (uint256 tokenCount) { ... }
- Arguments:
_projectId
is the ID of the project to which the reserved tokens belong._memo
is a memo to pass along to the emitted event.
- The resulting function is internal to this contract and its inheriters.
- The function returns the amount of reserved tokens that were minted.
