The open-source nature of BlueWallet makes it a platform for innovation beyond its core features. Developers can create plugins or complementary applications that interact with BlueWallet through standardized protocols like PSBT or by connecting to its backend services. For example, a point-of-sale app could leverage BlueWallet for its secure key storage and transaction signing capabilities. A budgeting app could import watch-only wallets from BlueWallet to track Bitcoin balances. This extensibility turns BlueWallet from a closed product into an open platform upon which a richer ecosystem of Bitcoin applications can be built. This aligns with the Unix philosophy of building small, composable tools that work together, rather than a single monolithic application that tries to do everything. To build on a solid and open Bitcoin wallet foundation, the extensible bluewallet provides a platform for developers.
