Compile errors ... EthereumTransaction, EthereumAddress

Hi.... thanks for making this library...

In the example project, I get the following compile errors:

Elrond Signing Not Working via TrustSDK

The same thing works fine with TrustWalletCore

Confirming transaction problem.

The DApp browser has been removed from the iOS version of Trust Wallet, so I went through all the steps to connect to pancakeswap on safari web browser to my trust wallet, but when I swap tokens on exchange.pancakeswap.finance it takes me back to my trust wallet to confirm the transaction, but there’s no option it gives me to confirm the transaction, it just takes me to my trust wallet main page. Please help.
Thank you.

About single sign on

Does trust adopt single sign on technology?

Impossible to verify the signature

Good afternoon.

I've tried to verify the signature, but, unfortunately, I couldn't do that (I get 'false').

Signature created by: Trust.signMessage()

I've used this approach for verifying:

let hash = Crypto.hash(messageData)
let isValid = Crypto.verify(signature: signed, message: hash, publicKey: myWalletAddress.data(using: .utf8)!)

And two more things:

1. signature verification is success on the https://etherscan.io/verifySig
2. signatures, created for the same message on Android and iOS, are different

EthereumTransaction.ContractGeneric example

Hello!

Trying to sign eth contract method call with TrustSDK/WalletCore, then try to sign this data with sdk_sign URL Scheme. TrustWallet responds with the sign_error. Any example of how we can sign a contract call correctly?

    let signerInput = EthereumSigningInput.with {
      $0.toAddress = "0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D"
      $0.chainID = BigInt("1").serialize()!
      $0.nonce = BigInt("477").serialize()!
      $0.gasPrice = BigInt("2112000000").serialize()!
      $0.gasLimit = BigInt("21000").serialize()!
      $0.privateKey = wallet.getKeyForCoin(coin: .ethereum).data
      $0.transaction = EthereumTransaction.with {
        $0.contractGeneric = EthereumTransaction.ContractGeneric.with {
          $0.data = Data(hexString:"ad5c4648")!
          $0.amount = BigInt("0").serialize()!
        }
      }
    }

If we use erc20 transfer – it's all ok, but no success with ContractGeneric.

pod 'TrustSDK'

error: `'init' is inaccessible due to 'internal' protection level`

I am using TrustWalletCore(wallet-core) instead of TrustCore(trust-core) in TrustSDK-iOS

In TrustCore use EthereumTransaction for Transaction.
In TrustWalletCore I use EthereumSigner for Transaction.

Following is my code

TrustSDKObjC.swift

@objc
  public func signTransaction(_ gasPrice: String, _ gasLimit: UInt64, _ address: String, amount: String, success: @escaping (Data) -> Void, failure: @escaping (NSError) -> Void) {
    /*
      let transaction = EthereumTransaction(
          nonce: 0,
          gasPrice: BigInt(gasPrice)!,
          gasLimit: BigInt(gasLimit),
          to: EthereumAddress(string: address)!,
          amount: BigInt(amount)!,
          payload: .none
      )
      */
      
      let transaction = EthereumSigner (
          gasPrice: gasPrice.data(using: .utf8)!,
          gasLimit: gasLimit,
          to: EthereumAddress(string: address)!,
          amount: amount.data(using: .utf8)!,
          payload: .none
      )

      signTransaction(transaction) { result in
          switch result {
          case .success(let signedMesssage):
              success(signedMesssage)
          case .failure(let error):
              failure(error as NSError)
          }
      }
  }

But getting following error

Sources/TrustSDK/ObjCWrapper/TrustSDKObjC.swift

error: 'init' is inaccessible due to 'internal' protection level
note: 'init' declared here

Have you thought about creating the SDK for flutter as well?

Since flutter supports multiple platforms, it can be very useful.

Conect

Member 'init' cannot be used on type 'Address'

TrustCore (0.2.2)
TrustSDK (0.0.1)

Swift 4

P.S. I think there must be an EthereumAddress. Not an Address.

Add Sign Personal message

Hello

We need an api call that would return public information about an active wallet such as network, title, address, balance, etc.

@madcake please make it for Android too

Add sign transaction + send parameter

Can we add a parameter to send transaction as well? Requested by the users.

@alejandro-isaza can you pass me a flag? I will handle that on my side then

@madcake can we do the same on Android side?

Improve TrustSDK documentation

• Add LSApplicationQueriesSchemes to configuration section.
• Document TrustButton

D

Yes

Add PayWithTrust button to TrustSDK

To simplify integration for developers, this would help to get started quickly

no such module

User reported:

thanks for TrustSDK this is great, want to integrate it in iOS project but got problems like no TrustSDK "no such module", have tried all type of general solution but no luck,

followed this link : https://github.com/TrustWallet/TrustSDK-iOS

please help me how can i integrate it in my project (need steps).

pod install giving issue.

On pod install getting error : "Unable to find a specification for TrezorCrypto (~> 0.0.8) depended upon by TrustCore"

Incorrect assign to transaction payload field

Hi, I have an issue when I try to send transaction with a "payload" field. For Example, when I send transaction with some data to TrustWallet:

var transaction = Transaction(gasPrice: BigInt(21), gasLimit: 21000, to: address)
transaction.amount = amount
transaction.payload = Data(hexString: "0x8f834227000000000000000000000000000000005224") //some data

trustSDK.signTransaction(transaction) { [weak self] signedTransaction in
    let alert = UIAlertController(title: "Signed Transaction", message: signedTransaction.hexString, 
        preferredStyle: .alert)
    alert.addAction(.init(title: "OK", style: .default, handler: nil))
    self?.present(alert, animated: true, completion: nil)
}

it doesn't display at screen:

I think it happened because transaction data is base64 encoded string and TrustWalletSDK can't parse it correctly. If change this code (in source TrustWalletSDK - > TrustWalletSDK.swift -> handleSignTransaction function):

 transaction.payload = components.queryParameterValue(for: "data").flatMap({ Data(hexString: $0) })

for something like this:

let data = components.queryParameterValue(for: "data").flatMap({ String($0) })!
let dataEncoded = Data(base64Encoded: data)!
transaction.payload = dataEncoded

now it's work correct:

Trust

Questions on the functional

Good afternoon.

Tell me, please, how can I decode signedTransaction data to Transaction object?

On Android I've done like this:

val tx = Geth.newTransactionFromRLP(Numeric.hexStringToByteArray(response.result))

Thank you in advance.

Tryst

We need that api calls for transaction and message signing also return the wallet address

@madcake please make it for Android too

Add signing message support

Wallet Connect doesn't work properly for IOS

Description
Although Trust has Wallet connect (nice!), it doesn't work if you close the app.

When the Wallet Trust App is in the background or closed, and you try to use the Dapp, the Dapp will send the transaction to be signed by the wallet. The issue is that if the app is not opened this message is lost. Furthermore, if you open later Trust wallet Dapp on top of not getting the messages sent while it was inactive, it doesn't get any new messages either.

My best guess is that, once the websocket is broken, it doesn't recover and recreate a new websocket using the topic id.

Other wallets, like Metamask allow the app to be in the background

How to reproduce

1. Go to any Dapp, like Uniswap
2. Connect using Wallet Connect
3. Try to swap 2 tokens, see how the transaction is shown in Trust ✅
4. Close the app
5. Open the app, see how the transaction is NOT shown in Trust automatically ❌
6. Try to swap 2 tokens again, see how the transaction is NOT shown in Trust ❌

Not working as expected

The SDK implementation or even the example is not working on my iPhone XR. It opens the Trust Wallet app but does nothing.
