Allow your users to have wallets with money-like balances for value / assets holding and transfering. Supports multiple currencies. Useful to add append-only, multi-asset wallets to your Rails app with balances, transfers, FIFO allocations, row-level locking, and full audit trails. Use it for in-game resources, reward apps, marketplace balances, gig-economy earnings, and internal value transfers between app users.
