During their work on the canopy-network/canopy repository, Blackground focused on improving the staking user interface by addressing a bug related to the max button when staking as a delegate. They refactored the input conversion and formatting logic to ensure that only floor-based integer amounts are used, enforcing precise floor division when converting to the smallest currency unit. By updating the onClick logic and the toUCNPY utility, Blackground guaranteed integer results for uCNPY, reducing failed staking operations and enhancing numeric correctness. Their work, using JavaScript and React, contributed to a smoother and more reliable staking experience for end users.
