Pocketful

Pocketful is a wallet and payments application built by a three-seat software factory in BAND Desktop. Our API Engineer, UI Designer, and independent Reviewer collaborated in one room, handed work to each other, and checked the results before acceptance. Their reusable mandates, full room log, and commit history are included in the public repository so the factory can be inspected and run again. The application supports wallet balances, payments, requests, bill splitting, holds, refunds, and historical corrections. Financial amounts use integer minor units. Transfers are atomic, retries are idempotent, and balances cannot become negative. We delivered separate Docker services for all four hackathon stages and verified the final stage against the supplied harness. The video shows the agents’ handoffs and review alongside a working browser demo. The hosted link shows the team’s live wallet; the repository’s stage-4 folder contains the final staged submission.
