Develop Samsung Blockchain
docgetting started the following steps should be followed before integrating the samsung blockchain platform sdk prepare samsung galaxy device to run your apk check your development environment android minimum api level for samsung blockchain platform sdk 24 noteminimum build level for samsung blockchain platform sdk is 21, but will properly work from level 24 configure your ide to integrate samsung blockchain platform sdk with your android app create an “aar” directory if you don’t have one, and add the blockchainplatformsdk_1 2 03 aar to ”aar” directory in your android project go to gradle scripts > build gradle and enter the following dependencies dependencies { repositories { flatdir{ dirs 'aar' } } implementation name 'blockchainplatformsdk_1 2 03', ext 'aar' // network implementation 'com squareup retrofit2 retrofit 2 6 0' implementation 'com squareup retrofit2 converter-gson 2 6 0' implementation 'com squareup okhttp3 logging-interceptor 3 8 0' implementation 'com google code gson gson 2 8 5' // web3j implementation 'org web3j core 4 8 8-android' // for check developer mode implementation 'org ini4j ini4j 0 5 4' // dagger implementation 'com google dagger dagger 2 21' annotationprocessor 'com google dagger dagger-compiler 2 21' implementation "io reactivex rxjava2 rxjava 2 2 8" implementation "io reactivex rxjava2 rxandroid 2 1 1" // protobuf implementation 'com google protobuf protobuf-java 3 9 1' implementation 'com google protobuf protobuf-gradle-plugin 0 8 10' } import the package into your code import com samsung android sdk blockchain *; samsung blockchain platform sdk supports 2 kinds of hardware wallet samsung blockchain keystore ledger's devices like nano x, nano s notetransactions on evm-compatible networks binance smart chain, klaytn, polygon, avalanche c-chain and fantom are signed from the hardware wallets using the same pathway as that of ethereum for these transactions, currency unit displayed on hardwarewallet, such as samsung keystore or ledger, will show eth as currency unit instead of bnb, klay, matic, avax and ftm development setting guide for each environment is as follows integration with samsung blockchain keystore samsung blockchain keystore is compatible with selected samsung devices only you need to have one of selected samsung devices to run your app with samsung blockchain keystore please refer to the restrictions check your development environment android minimum api level for samsung blockchain keystore 28 notesamsung blockchain platform sdk requires samsung blockchain keystore that is higher than 1 5 1 download the samsung blockchain keystore sdk set 'developer mode' to test your app without app id verification you can find more information about app id scw_app_id , here add "blockchainkeystoresdk_v1 6 0 aar" to "aar" directory in your android project go to gradle script > build gradle and add below dependency dependencies { // keystore sdk implementation name 'blockchainkeystoresdk_v1 6 0', ext 'aar' } integration with nano x or nano s by ledger there is no restrictions to link with ledger device so any samsung galaxy mobile is ok to test your app which is integrated with samsung blockchain platform sdk when you sign with ledger device check your development environment ledger nano x 1 2 4-1 or higher ledger nano s 1 6 or higher ledger ethereum app 1 9 8 or higher you can refer ledger's guide page to get started go to gradle > build gradle and add below dependency dependencies { // ledger implementation 'com ledger lib ledger-android-library 1 2 2' }

docapi implementation samsung blockchain keystore api level get instance get seedhash check for mandatory app update is root seed backed up get supported coins get hd path get a list of addresses get a list of extended public keys sign a transaction is reboot authentication required go to samsung blockchain keystore settings handle error codes deeplinks samsung blockchain keystore api level samsung blockchain keystore api level plays a key role to ensure that the required api level of samsung blockchain keystore on a user’s device is properly installed to support the api that your android app tries to call for example, if your android app is trying to implement a new samsung blockchain keystore api that requires “api level 2”, your android app will need to check whether samsung blockchain keystore app installed on user’s device also supports api level 2 if a user’s app supports api level 1, then your app will need to guide users to update samsung blockchain keystore app to the latest version users can be directed to the update page in galaxy store otherwise, there will be a runtime exception due to api level exception when calling apis with level higher than the level supported by the user’s version the api level for each api will be mentioned in the javadoc, under “since” title, and developers can call “getkeystoreapilevel api” to check the current api level on the user’s device your android app will need to check the api level whenever needed – it may be at the beginning of running samsung blockchain keystore app or every time your app calls an api public void getkeystoreapilevel { int keystoreapilevel = scwservice getinstance getkeystoreapilevel ; boolean iskeystoreapisupported = keystoreapilevel > 0; } get instance scwservice getinstance will need to be used to call any of the apis provided by samsung blockchain keystore if samsung blockchain keystore is supported on the device, an instance will be returned if it is not available on the device, then null will be returned if null is returned, it means samsung blockchain keystore is not supported on the user’s device a different keystore or a wallet needs to be used scwservice scwserviceinstance = scwservice getinstance ; get seed hash getseedhash api aims to help developers distinguish two things 1 check whether user has set up samsung blockchain keystore 2 check whether root seed recovery phrase has been changed or not every time a new root seed or a wallet is created or restored, the seed hash in a string value will be changed actually, this is not the preimage of the real seed, but a pseudo hash value so, it is not possible to calculate the real seed with the pseudo one it is strongly recommended for the application to cache the returned hash value to reduce the number of times to check the derived address’s validity if the returned value is same as cached, the derived addresses are still valid, so the application keeps using these addresses otherwise, the application should refresh the addresses from new seed with getaddresslist or getextendedpublickeylist api whenever the application starts, it needs to call getseedhash in case that the returned value is a zero-length string, it means that there is no wallet in the samsung blockchain keystore so, the application ui needs to guide users to jump to samsung blockchain keystore to create a wallet with scwdeeplink main deeplink public void getseedhash { string seedhash = scwservice getinstance getseedhash ; boolean initialized = seedhash != null && seedhash length > 0 ; } check mandatory app update checkformandatoryappupdate api is to help developers check if a user must update samsung blockchain keystore because samsung blockchain keystore handles only one task at a time, make sure to not call the checkformandatoryappupdate api in the background as it may cause other api calls or requests to be cancelled if a mandatory app update is needed, users can be directed to the galaxy store using a deeplink, scwdeeplink galaxy_store otherwise, users will see the mandatory app update popups during an operation process, such as signing a transaction, and will need to update samsung blockchain keystore before proceeding note scwservice scwcheckformandatoryappupdatecallback will need to be implemented correspondingly scwservice scwcheckformandatoryappupdatecallback callback = new scwservice scwcheckformandatoryappupdatecallback { @override public void onmandatoryappupdateneeded boolean needed { if needed { startdeeplink scwdeeplink galaxy_store ; } } }; scwservice getinstance checkformandatoryappupdate callback ; how to handle the returned value a boolean needed value of whether a mandatory update is needed or not will be returned if needed, developers will need to guide users to go to samsung blockchain keystore app page in galaxy store to update is root seed backed up isrootseedbackedup api helps developers check if there is a backup of root seed since a user can create a wallet without a backup of root seed, developers can advise the user to make root seed backup if a backup of root seed is needed, the users will be directed to the page which backs up the mnemonic phrases in the samsung blockchain keystore using a deep link, scwdeeplink backup_wallet boolean isbackedup = scwservice getinstance isrootseedbackedup ; if !isbackedup { startdeeplink scwdeeplink backup_wallet ; } how to handle the returned value the result of root seed backup will be returned in a boolean type get supported coins getsupportedcoins api is used to find out which type of cryptocurrencies are supported, in case there is a different logic that developers must implement for different cryptocurrencies it is returned in an int array of standard coin types according to bip standard – for example, 60 for ethereum int[] supportedcoins = scwservice getinstance getsupportedcoins ; stringbuilder sb = new stringbuilder ; sb append "supported coins" append '\n' ; for int i = 0; i < supportedcoins length; i++ { sb append '[' append i append "] " append supportedcoins[i] append '\n' ; } string s = sb tostring ; get hd path gethdpath api helps developers derive hd path for a specified coin type this api can be used as a parameter when deriving an address and requesting to sign a transaction note that utxo-based cryptocurrency, such as bitcoin will not be supported for this api no callback will be needed for this api as hd path in string type will be returned immediately //derive hd path for the cryptocurrency that your app supports string ethereumhdpath = scwservice gethdpath scwcointype eth, 0 ;

} call getkeystoreapilevel api to see if the current samsung blockchain keystore being used, properly supports the features that your android app is currently aiming for if the required api level is higher than the current samsung blockchain keystore level, users are directed to samsung blockchain keystore app page in galaxy store through the provided deeplink to update // check installed api level else if scwservice getinstance getkeystoreapilevel < 1 { // if api level is lower, jump to galaxy apps to update keystore app mcontract showdialog "" , "ok" , "the api level is too low jump to galaxy store" , -> mcontract launchdeeplink scwdeeplink galaxy_store ; } check if a user has set up the samsung blockchain keystore and is ready to use it by calling getseedhash api if the seed hash value in string is zero-length, this means the user has not set up samsung blockchain keystore yet hence, your app will need to guide the user to jump to samsung blockchain keystore via deeplink to either create or import a wallet // check seed hash exist else if scwservice getinstance getseedhash length == 0 { // if seed hash is empty, // jump to blockchain keystore to create or import wallet mcontract showdialog "" , "ok" , "the seed hash is empty " + "jump to blockchain keystore to create/import wallet " , -> mcontract launchdeeplink scwdeeplink main ; } if the getseedhash api returned value is not zero-length, it means that the user has successfully set up samsung blockchain keystore if there is a previously saved or cached seed hash value, compare the two seed hash values if those two values are not equal, nor if there is no such saved cached seed hash value, then the address has to be checked again if the seed hash value has been changed, it means the master seed has been changed as well, meaning the address that your android app was linked to may no longer be the same address // check seed hash cached else if !textutils equals cachedseedhash, scwservice getinstance getseedhash { // if the seed hash is different from cached, update seed hash and address // go to next activity final string ethereumhdpath = "m/44'/60'/0'/0/0";
