Silent payments is not well supported by wallets and exchanges though
Discussion
The BIP has been merged into the bitcoin BIP repo. The math is sound.
Wallets like Cake, Wasabi, Seedsigner, Dana wallet, Silentium, BitBox 02 already have send and receive support from most.
Libraries like BDK are working on it (mainly waiting for Josie's PR merge to the secP library to do most of the heavy lifting).
Exchanges, would implement it eventually once they understand how this saves them in terms of efficiency. Once again the math is SOUND!!!!!!!
Amazing!!
