Server-Side Guide

If your server application (most likely on Linux) language supports FFI to C, it is possible to call wallet core.

Golang

Here is a step by step example of cgo, using Wallet Core docker image.

  1. Run docker run -it trustwallet/wallet-core The librabry is already built in this image (Build instructions here) Note: may not be the most recent version.

  2. Install go: apt-get update && apt-get install golang (or download from here go1.13.3, configure GOROOT and append GOROOT/bin to PATH).

  3. Save the sample code below to file called main.go

package main

// #cgo CFLAGS: -I/wallet-core/include
// #cgo LDFLAGS: -L/wallet-core/build -L/wallet-core/build/trezor-crypto -lTrustWalletCore -lprotobuf -lTrezorCrypto -lc++ -lm
// #include <TrustWalletCore/TWHDWallet.h>
// #include <TrustWalletCore/TWString.h>
import "C"

import "fmt"

func main() {
	fmt.Println("==> calling wallet core from go")
	str := C.TWStringCreateWithUTF8Bytes(C.CString("confirm bleak useless tail chalk destroy horn step bulb genuine attract split"))
	defer C.TWStringDelete(str)
	valid := C.TWHDWalletIsValid(str)
	fmt.Println("<== mnemonic is valid: ", valid)
}
  1. Compile it by go build -o main
  2. Run ./main and you will see the output below:
==> calling wallet core from go
<== mnemonic is valid:  true
  1. You might want to copy and run main outside of the docker container, make sure you have libc++1 and libc++abi1 installed in your host Ubuntu.
