EthereumKit is a free, open-source Swift framework for easily interacting with the Ethereum.

Hi @yuzushioh

I have question. I need to send Ethereum's tokens (USDT). I know that for sending tokens i must match smart-contract data such as parameter of RawTransaction(field Data). Question: Do you how to resolve that question ?

Thanks

Hey, I'm graphic designer and my aim is supporting open source projects and make my portfolio better. So, I can contribute on your project with making logo design. I am waiting your feedback! Have a nice day! :)

ya , ethereumkit installation is completed , i have add an ethereumkit module its shows some error,please check me .Missing required module 'secp256k1'

JSONRPCError.responseError(code: -32000, message: "insufficient funds for gas * price + value", data: nil)

an error occurred when i sendrawTransction

When I update the project and rebuild the carthage frameworks, and then build the project for release scheme (Cmd+Shift+I), then the compilation freezes on the SentTransaction.swift file and the build doesn't go anywhere.

Currently, I have no idea why this happens.

Hello! Thanks a lot for your package, great job!

Carthage version: 0.29.0. Swift version: 4.1.2 (swiftlang-902.0.54 clang-902.0.39.2). Target: x86_64-apple-darwin17.5.0.

But today, after your changes, when you updated CryptoSwift to 0.10.0 and dependency version to 9.0, I have the following situation after carthage update --platform iOS:

So dependency was skipped and I cannot to use its secp256k1. I tried to use --no-use-binaries flag (as Google prompted), then I gave within logs:

CryptoEthereumSwift/CryptoEthereumSwift/Source/EllipticCurveEncrypterSecp256k1.swift:2:8:
error: module file's minimum deployment target is ios9.0 v9.0

Although I already have 11.3.

I have change github "krzyzanowskim/CryptoSwift" "0.9.0" to github "krzyzanowskim/CryptoSwift" "0.10.0" in my Cartfile directly and all my "installation" problems has expired.

But again, I have the following problem:

let wallet: Wallet = Wallet(network: .main, privateKey: privateKey)
compiler error: Type of expression is ambiguous without more context

When I change it to the following code:

let wallet: Wallet = Wallet(network: .main, privateKey: UserData.privateKey, debugPrints: true)

I get:

Can you help me?

Hi, I am not sure if it is correct that "compressed: true" is used in this place. Could it be a potential issue, or should it be like that?

See my debug process:

(lldb) po wallet.ether?.description
▿ Optional<String>
  - some : "399979/1000000"

(lldb) po wallet.ether?.decimalExpansion(precisionAfterComma: 4)
▿ Optional<String>
  - some : "0.0000"

(lldb) po wallet.ether?.decimalExpansion(precisionAfterComma: 5)
▿ Optional<String>
  - some : "0.00000"

(lldb) po wallet.ether?.decimalExpansion(precisionAfterComma: 6)
▿ Optional<String>
  - some : "0.399979"

(lldb) po wallet.ether?.decimalExpansion(precisionAfterComma: 8)
▿ Optional<String>
  - some : "0.39997900"

wallet.ether is a EthereumKit.BDouble

It's so strange if I do not put enough precision to represent the floating number, it will always return 0.000...

This code returns private key data with a length of 31 byte, which is not correct. The data doesn't have leading zero byte.

        let mnemonic = "half try deer tray hockey ball notable abstract affair main desert session"
        let seed = Mnemonic.createSeed(mnemonic: mnemonic)
        let hdWallet = HDWallet(seed: seed, network: Network.private(chainID: 0, testUse: false))
        let privateKey = try! hdWallet.privateKey(at: 1).raw

The expected private key is 0x007179e85007a04d2a9cae63be80326aa2c218f75394b7d37ccd1b660c8b180d but the actual is 0x7179e85007a04d2a9cae63be80326aa2c218f75394b7d37ccd1b660c8b180d .

Currently, requests made through http client are getting 10 seconds timeout, but it is too short for a real world use case. It would be good to have it either set back to default value (60 seconds) or ability to provide this value by library users.

Infra's Endpoint has change https://mainnet.infura.io/{project ID} to https://mainnet.infura.io/v3/{project ID}. so we need to fix it. Otherwise, the new endpoint of infra doesn't work.
