Is there a bitcoin SPV Wallet client on GitHub?
Could you please elaborate on whether there exists a Bitcoin Simplified Payment Verification (SPV) Wallet client available on GitHub? I'm specifically interested in finding a reliable and secure wallet implementation that utilizes SPV to validate transactions without the need for a full blockchain download. It would be greatly appreciated if you could provide me with a brief description of the wallet, its features, and any potential limitations it may have. Additionally, any recommendations or insights you have regarding the best practices for evaluating and choosing an SPV wallet would be invaluable.
