exchange to securely transmit service data. refer to the diagram and developer guide, security key & certificate creation guide, to complete the certificate registration and partner enrollment smoothly. certificates exchange process ensuring data security to prevent forgery and leakage of user card data, secure tokenization processing is required. json web token (jwt), which includes encryption and signature, has a validity time basis for verification, thus providing enhanced security. in particular, when generating this token, the key and certificate previously obtained through the certificate exchange process are used. process of generating and verifying security tokens notice depending on how partners provide content services to users, you can choose how to deliver data to the samsung wallet service. two ways to transfer wallet card data add to samsung wallet interface provides two methods for partners to deliver users digital content as wallet cards. data transmit link

button. as long as samsung wallet support is confirmed, you can generate a link containing the user's card data and configure the "add to samsung wallet" button to run the link when pressed, either on an application or web page. data transmit process data fetch link another method to transfer wallet card data is to include only the refid, which represents the user's content, in the "add to samsung wallet" link and transmit it to the samsung wallet service. when a user clicks the "add to samsung wallet" button, samsung servers refer to the get card data api information set on the wallet card and retrieve user content using the received refid to complete registration. data fetch process this method is suitable for providing user's data through email or mms messages where static links cannot be avoided. there is an option to secure these static links. data fetch process for static links setting up data synchronization on the partner portal, you can set up the wallet card information and configure the server interaction api that the content provider needs to prepare. this api is an interface for managing card registrations, deletions, information, and state changes to sync with those registered on samsung wallet. register wallet cards when a user card is added to samsung wallet, samsung wallet servers use the send card state api to communicate card registration and deletion status to the content provider, allowing them to manage content that needs to be synchronized with samsung wallet. when a wallet card is registered, added event is sent to the partner's server update wallet cards changes to the synchronization target content can be notified to the samsung wallet service through the update notification api. here, the value that distinguishes each piece of content is the refid that the partner must provide when registering the users’ wallet card. through the get card data api, samsung wallet servers can check the latest content information any time. if updates occur on the partner's side, updated event notifications should be sent to the samsung server in case users withdraw content from the partner's side in case users delete cards from samsung wallet notice both servers should verify requests using the authorization header of the api request. this authorization token is in jwt format, familiar from card data security. effortless wallet card registration

Samsung Wallet Terms

Connect with Hardware Wallet

wallet samsung blockchain platform sdk supports various cold wallets. it can be managed using hardwarewalletmanager, and can get an instance from sblockchain. currently, there are two types of hardwarewallet, samsung blockchain keystore and the ledger nano. get instance gethardwarewalletmanager is a callable instance of sblockchain. if the sblockchain instance is not initialized, an illegalstateexception will be thrown. try { hardwarewalletmanager hardwarewalletmanager = sblockchain.gethardwarewalletmanager(); } catch (illegalstateexception e) { // handling exception } connect the hardwarewallet should be connected to sign, create, or restore an account. the connect api requires two mandatory parameters, hardwarewallettype and whether to clear the saved accounts. the hardwarewallettype is used to target its connection. there are two connection types: usb and bluetooth, and is specific for the ledger nano x. for usb connections, the device must be connected through otg. a bonding state is required for bluetooth connections. to connect a ledger device, the latest ethereum application is installed on the ledger device and can be connected while running. if ready to connect, the connect api can be called. listenablefuturetask<hardwarewallet> connectiontask = hardwarewalletmanager.connect(hardwarewallettype, true); connectiontask.setcallback( new listenablefuturetask.callback<hardwarewallet>() { @override public void onsuccess(hardwarewallet hardwarewallet) { } @override public void onfailure(executionexception e) { throwable cause = e.getcause(); if (cause instanceof hardwarewalletexception) { // handling hardware wallet error } else if (cause instanceof rootseedchangedexception) { // handling root seed changed exception } } @override public void oncancelled(interruptedexception e) { } }); the parameters to take note of are as follows: hardwarewallettype : target hardwarewallet to connect. reset : whether to clear accounts. samsung blockchain platform sdk only supports one root seed for each hardwarewallet for account management. if the root seed is changed by resetting the hardwarewallet, when the connect api is called, onfailure is called and the rootseedchangedexception is returned. disconnect disconnect api is related to the target connection of the hardwarewallet. it is recommended to call it before closing your application or even before connecting to another hardwarewallet. if the disconnect api is not called, the broadcast receiver may continue to work. hardwarewalletmanager.disconnect(hardwarewallet); get connected hardwarewallet getconnectedhardwarewallet api returns an instance of the connected hardwarewallet. apis that use the root seed requires an instance of connected hardwarewallet, so they can get the hardwarewallet connected and call it before calling them. if no hardwarewallet is connected, a null is returned. hardwarewallet connectedhardwarewallet = hardwarewalletmanager.getconnectedhardwarewallet(); get supported coins hardwarewallet instance is returned through the hardwarewalletmanager that has apis that support its feature. getsupportedcoins api returns a list of cointype provided by the hardwarewallet and samsung blockchain platform sdk in common. list supportedcointypes = hardwarewalletmanager.getconnectedhardwarewallet().getsupportedcoins(); stringbuilder sb = new stringbuilder(); sb.append(“supported coins : ”).append(‘\n’); for (cointype cointype : supportedcointypes) { sb.append(‘[’).append(cointype.code).append(‘)’).append(‘\n’); } string s = sb.tostring(); get version getversion api returns its version. for samsung blockchain keystore, it returns the versionname of the keystore; and for the ledger it returns the version of the ledger application running. if you need a different behavior depending on the version, you can call this api to branch. hardwarewallet connectedhardwarewallet = hardwarewalletmanager.getconnectedhardwarewallet(); string version = connectedhardwarewallet.getversion(); get connection state isconnected api returns the state that the hardwarewallet instance is connected. if connected, it returns as true. otherwise, it returns as false. if (hardwarewallet.isconnected()) { hardwarewalletmanager.disconnect(hardwarewallet); }
