Getting Started with SDK

How to setup the AkashicPay SDK for use in your codebase

Installing

Install the package with

TypeScript

npm install @akashicpay/sdk
#or
yarn add @akashicpay/sdk

PHP

# Pre-Reqs
# Requires at least PHP 7.0 and either the gmp or bcmath extension

composer require akashic/akashic-pay

Java

# In case of Maven
<dependencies>
    <dependency>
        <groupId>com.akashicpay</groupId>
        <artifactId>AkashicPaySDK</artifactId>
        <version>[version]</version>
    </dependency>
</dependencies>

# In case of Gradle
dependencies {
  implementation 'com.akashicpay:AkashicPaySDK:[version]'
}

C#

$ dotnet add package AkashicPaySDK

Go

go get github.com/akashicpay/akashicpay-go

Register

Create an AkashicLink account and go through the registration process on AkashicPay.com including setting up callback URLs as desired, as described in the Quick Guide.

l2Address - Located at the top bar of AkashicLink

privateKey - Login AkashicPay -> KeyPair Settings -> Use the API/SDK KeyPair

Build

This example configuration uses many optional build arguments, for illustration purposes.

TypeScript

import type { IHttpClient, ILogger } from "@akashicpay/sdk";
import { ACDevNode, ACNode, AkashicPay, Environment } from "@akashicpay/sdk";
import axios from "axios";
import pino from "pino";
import { Environment } from "@akashicpay/sdk/src";

// use whatever secret management tool you prefer to load the private key
// from your AkashicLink account. It should be of the form:
// `"0x2d99270559d7702eadd1c5a483d0a795566dc76c18ad9d426c932de41bfb78b7"`
// In development, each developer could have their own, or omit this (and
// the l2Address), in which case the SDK will create and use a new pair.
// you can instead use your Akashic Link account's 12-word phrase, using the
// `build()` argument `recoveryPhrase`
const privateKey = process.env.akashicKey;
// this is the address of your AkashicLink account. Of the form "AS1234..."
const l2Address = process.env.l2Address;
// in development, you will use our testnet and testnet L1 chains
const environment =
  process.env.environment == "production"
    ? Environment.Production
    : Environment.Development;
// you're strongly encouraged to pass an instance of your preferred logger
const logger: ILogger = pino({ name: "AkashicPaySDK" });
// optional, the SDK will try to find the fastest node if omitted
const targetNode =
  environment == "development" ? ACNode.SingaporeDAI : ACDevNode.Singapore1;

// instantiate an SDK instance, ready to use
const akashicPay = await AkashicPay.build({
  privateKey,
  l2Address,
  environment,
  targetNode,
  logger,
});

You are now ready to use AkashicPay! To learn more about the different functions, go to the next page. Continue reading for more details about advanced setup of AkashicPay and testing.

Testing

You can also use AkashicPay with the AkashicChain Testnet & Sepolia (Ethereum) and Shasta (Tron) testnets, useful for local development and staging environments. To do this, follow the same setup as above, but use testnet versions of AkashicLink and testnet.akashicpay.com. The SDK setup is almost identical, though note that the "Development" environment must be used.

TypeScript

import { AkashicPay, Environment } from "@akashicpay/sdk";

const privateKey = process.env.akashicKey;
const l2Address = process.env.l2Address;

const akashicPay = await AkashicPay.build({
  privateKey,
  l2Address,
  environment: Environment.Development,
});

// Now, e.g. create a wallet on the Tron Shasta testnet
const { address } = await akashicPay.getDepositAddress(
  NetworkSymbol.Tron_Shasta,
  "EndUser123"
);

PHP

<?php

require "vendor/autoload.php";

use Akashic\AkashicPay;
use Akashic\Constants\Environment;
use Akashic\Constants\NetworkSymbol;

// production is the default environment.
// And in production, an otk must be specified
$akashicPay = new AkashicPay([
    'environment' => Environment::DEVELOPMENT,
    'privateKey' => getenv('akashicKey'),
    'l2Address' => getenv('l2Address'),
]);

// Now, e.g. create a wallet on the Tron Shasta testnet
$address = $akashicPay->getDepositAddress(NetworkSymbol::TRON_SHASTA, 'user123');

Java

import com.akashicpay.constants.APEnvironment;
import com.akashicpay.model.ACOtk;
import com.akashicpay.model.APDepositAddressResult;
import com.akashicpay.model.APNetworkSymbol;
import com.akashicpay.sdk.IAPSdk;

public class Main {

    public static void main(String[] args) throws Exception {
        String l2Address = "your l2Address";
        String privateKey = "your privateKey";

        ACOtk otk = APSdkFactory.createOtkFromKeyPair(privateKey, l2Address);

        IAPSdk sdk = APSdkFactory.createSDK(APEnvironment.Development, otk);

        APDepositAddressResult trxDepositAddress =
                sdk.getDepositAddress(APNetworkSymbol.TRX_SHASTA, "EndUser123");
    }
}

C#

using AkashicPaySDK;
using AkashicPaySDK.Constants;
using AkashicPaySDK.Model;

namespace ApSdkTests;

public class Example
{
    public static async Task Main(string[] args)
    {
        var l2Address = "your l2Address";
        var privateKey = "your privateKey";
        var otk = ApSdkFactory.CreateOtkFromKeyPair(l2Address,privateKey);

        var sdk = await ApSdkFactory.CreateSdk(APEnvironment.Development, otk);

        var trxDepositAddress = await sdk.GetDepositAddressAsync(TronShastaNetworkSymbol.Value, "test005");
    }
}

Go

import (
	"os"

	akashicpay "github.com/akashic/go-sdk"
)

apKey := os.Getenv("ApTestKey")
apL2Address := os.Getenv("ApTestL2Address")

// in development, you will use our testnet and testnet L1 chains
apEnv := akashicpay.Development

// instantiate an SDK instance, ready to use
ap, err := akashicpay.NewAkashicPay(apKey, apL2Address, apEnv, "")

if err != nil {
// handle error
}

// Now, e.g. create a wallet on the Tron Shasta testnet
dA, err := ap.GetDepositAddress(akashicpay.Tron_Shasta, "user123", "")
