Stack Wallet, the versatile cryptocurrency wallet that caters to a diverse array of digital currencies, alongside its counterpart Stack Duo—a wallet dedicated to monero and bitcoin—have unveiled a major update. The newest version, Stack Duo v1.2.0, now incorporates Tor support for both Monero and Bitcoin. This includes the use of .onion addresses, significantly bolstering user privacy and security. Furthermore, Bitcoin transactions have been enhanced through the integration of Replace-by-Fee (RBF) and Child-Pays-for-Parent (CPfP) functionalities. The creators of Stack Wallet are optimistic that “Bitcoin maximalists,” who might have previously been reluctant to use Stack Wallet due to its multi-cryptocurrency support, will be inclined to explore Stack Duo, which is strictly tailored for monero (**XMR**) and bitcoin (**BTC**).
