SLPWallet Demo 🐍 (Built with VIPER)

This app demonstrates how to use the SLPWallet iOS SDK in a wallet. With it, you can:

Receive SLP tokens.
Send SLP tokens.
Receive BCH to fund your SLP transfers.
View your token balances.
View your BCH balance.
View your mnemonic to backup your wallet.
Restore your wallet from a mnemonic.

Get Started

Playing with the SDK

You can create an SLP wallet in a few lines only. This code comes from WalletManager.swift. All other files are UI related code and don't concern the SDK.

//
// ...
//

import SLPWallet

//
// ...
//

class WalletManager {
    
    static let shared = WalletManager()
    
    var wallet: SLPWallet
    
    var observedToken: BehaviorRelay<SLPToken>?
    var observedTokens: PublishSubject<SLPToken>?
    
    init() {
        do {
            wallet = try SLPWallet(.mainnet)
            setup()
        } catch {
            fatalError("It should be able to construct a wallet")
        }
    }

    //
    // ... 
    //
}

extension WalletManager: SLPWalletDelegate {
    
    // Call with SLPWalletDelegate ❗️💥🚀
    func onUpdatedToken(_ token: SLPToken) {
        
        // Notify
        if let observedToken = self.observedToken
            , observedToken.value.tokenId == token.tokenId {
            observedToken.accept(token)
        }
        
        // Notify
        if let observedTokens = self.observedTokens {
            observedTokens.onNext(token)
        }
        
    }
}

After creating your wallet, you can start sending tokens. This file describes how to send tokens: SendTokenInteractor.swift. Below you can see a preview of the file.

//
// ...
//

class SendTokenInteractor {
    
    fileprivate let bag = DisposeBag()
    
    func sendToken(_ tokenId: String, amount: Double, toAddress: String) -> Single<String> {
        return Single<String>.create { single in
            WalletManager.shared.wallet
                .sendToken(tokenId, amount: amount, toAddress: toAddress) // That's it 💥🚀
                .subscribe(onSuccess: { txid in
                    single(.success(txid))
                }, onError: { error in
                    single(.error(error))
                })
                .disposed(by: self.bag)
            return Disposables.create()
        }
    }
}
