Key facts:
-
Cake Wallet, BlueWallet and Silentium now allow you to send Silent Payments.
-
The SeedSigner hardware wallet will implement silent payments in the future.
Although still in the experimental phase, the BIP-352 standard, also known as silent payments, can already be used in some Bitcoin wallets. Specifically in three: Cake Wallet, BlueWallet and Silentium. For its part, the hardware wallet SeedSigner has begun to create the infrastructure to implement them.
According to the docs from silentpayments.xyz, Both CakeWallet and Silentium allow you to send and receive silent payments within an architecture where no information or data is revealed to third parties. BlueWallet, which only allows sending them at the moment, does not have such an infrastructure.

The same docs recommend being careful when using Silentium, an open source bitcoin wallet. created as proof of concept of the silent payments. On the other hand, SeedSigner added basic experimental support for your hardware wallet.
According to Keith Mukai, lead developer of the build-at-home hardware wallet, he only created a “stand to set up an air-gapped BIP 352 silent payment wallet.” He says that for a full implementation, there is still some work to be done on how the spending side of a silent transaction works.

According to the same developer, the silent payments function It is only available for now in the developer version of your deviceas the plugin still requires auditing and bug fixing, among other fixes.
Among the possibilities that SeedSiger will have with the BIP 352 standard are:
- generate a reusable and shareable payment address,
- export the public key of the signing key
- export scan key private key
What are silent payments?
In simple words, and as reported by CriptoNoticias, the silent payments allow, through an underlying process of the protocol it uses, the generation of a unique Taproot address. This Taproot address is single-use and is the product of the combination of three keys; it is generated every time the Silent Payments static address is used. From this unique address, the recipient and only he himself can spend the bitcoins sent to him.
The resulting unique, single-use Taproot address makes the payment appear exactly like any other Taproot payment on the chain, thus preventing an outside observer from even being able to tell that silent payments were used, let alone link the payments to a specific silent payment address.

Privacy is said to be caused by an underlying process because, in practice, silent payments They give the convenience of using static addresses of bitcoin and receive payments over and over again to the same address.
These silent transactions improve user privacy. They do this by avoiding adding additional data on-chain and saving space on the Bitcoin Blockchain.
How do silent payments work?
The protocol removes the need for on-chain payment notifications, leveraging “information that was already in the transaction to tell the recipient when funds are destined for them,” according to silentpayments.xyz.
These silent transactions are a more modern version of “stealth addresses” and advances in reusable address technology. All of these protocols have a similar purpose.
In simple terms, they help prevent the linking of the sending and receiving addresses, automatically generated by them, with the actual bitcoin addresses where the recipient is paid.
