XDC3Delphi

XDC3Delphi SDK with support for XRC20 and XRC721 smart contract.

Dependencies

Before you can compile this project, you will need to clone the following repositories, and then add them to your Delphi search path:

git clone https://github.com/XDCFoundation/XDC3Delphi.git
git clone https://github.com/rvelthuis/DelphiBigNumbers
git clone https://github.com/Xor-el/SimpleBaseLib4Pascal
git clone https://github.com/Xor-el/HashLib4Pascal
git clone https://github.com/Xor-el/CryptoLib4Pascal
git clone https://github.com/svanas/delphereum.git

Search path

Assuming your project is named SDKClient and you have a projects directory with this structure...

SDKClient
XDC3Delphi 
CryptoLib4Pascal
delphereum
DelphiBigNumbers
HashLib4Pascal
SimpleBaseLib4Pascal

...then this is your Delphi search path:

../delphereum;../DelphiBigNumbers/Source;../CryptoLib4Pascal/CryptoLib/src/Interfaces;../CryptoLib4Pascal/CryptoLib/src/Math;../CryptoLib4Pascal/CryptoLib/src/Utils;../CryptoLib4Pascal/CryptoLib/src/Security;../HashLib4Pascal/HashLib/src/Interfaces;../HashLib4Pascal/HashLib/src/Utils;../CryptoLib4Pascal/CryptoLib/src/Utils/Randoms;../HashLib4Pascal/HashLib/src/Base;../HashLib4Pascal/HashLib/src/KDF;../HashLib4Pascal/HashLib/src/Nullable;../HashLib4Pascal/HashLib/src/NullDigest;../HashLib4Pascal/HashLib/src/Checksum;../HashLib4Pascal/HashLib/src/Hash32;../HashLib4Pascal/HashLib/src/Hash64;../HashLib4Pascal/HashLib/src/Hash128;../HashLib4Pascal/HashLib/src/Crypto;../HashLib4Pascal/HashLib/src/Interfaces/IBlake2BParams;../HashLib4Pascal/HashLib/src/Crypto/Blake2BParams;../HashLib4Pascal/HashLib/src/Interfaces/IBlake2SParams;../HashLib4Pascal/HashLib/src/Crypto/Blake2SParams;../CryptoLib4Pascal/CryptoLib/src/Crypto/Digests;../CryptoLib4Pascal/CryptoLib/src/Asn1/Pkcs;../CryptoLib4Pascal/CryptoLib/src/Asn1;../CryptoLib4Pascal/CryptoLib/src/Utils/Encoders;../SimpleBaseLib4Pascal/SimpleBaseLib/src/Bases;../SimpleBaseLib4Pascal/SimpleBaseLib/src/Utils;../SimpleBaseLib4Pascal/SimpleBaseLib/src/Interfaces;../CryptoLib4Pascal/CryptoLib/src/Asn1/RossStandart;../CryptoLib4Pascal/CryptoLib/src/Asn1/Oiw;../CryptoLib4Pascal/CryptoLib/src/Asn1/Nist;../CryptoLib4Pascal/CryptoLib/src/Asn1/Misc;../CryptoLib4Pascal/CryptoLib/src/Asn1/TeleTrust;../CryptoLib4Pascal/CryptoLib/src/Asn1/CryptoPro;../CryptoLib4Pascal/CryptoLib/src/Crypto/Prng;../CryptoLib4Pascal/CryptoLib/src/Utils/Rng;../CryptoLib4Pascal/CryptoLib/src/Crypto/Engines;../CryptoLib4Pascal/CryptoLib/src/Crypto/Parameters;../CryptoLib4Pascal/CryptoLib/src/Crypto;../CryptoLib4Pascal/CryptoLib/src/Math/EC;../CryptoLib4Pascal/CryptoLib/src/Crypto/EC;../CryptoLib4Pascal/CryptoLib/src/Math/EC/Endo;../CryptoLib4Pascal/CryptoLib/src/Asn1/Sec;../CryptoLib4Pascal/CryptoLib/src/Asn1/X9;../CryptoLib4Pascal/CryptoLib/src/Asn1/CryptLib;../CryptoLib4Pascal/CryptoLib/src/Math/Raw;../CryptoLib4Pascal/CryptoLib/src/Math/EC/Multiplier;../CryptoLib4Pascal/CryptoLib/src/Math/EC/Abc;../CryptoLib4Pascal/CryptoLib/src/Math/Field;../CryptoLib4Pascal/CryptoLib/src/Math/EC/Custom/Sec;../CryptoLib4Pascal/CryptoLib/src/Math/EC/Custom/Djb;../CryptoLib4Pascal/CryptoLib/src/Crypto/Signers;../CryptoLib4Pascal/CryptoLib/src/Crypto/Generators;../CryptoLib4Pascal/CryptoLib/src/Crypto/Macs;../XDC3Delphi

To Configure Any Compatible Network

Some config changes require in web3.pas in delphereum repository you just cloned in your local machine.

For Example to setup Apothem Network changes require in web3.pas file

Step 1

Add any Comapatible Network name in TChain

For Example

type

TChain = (

Ethereum,

Apothem,

...

);

Step 2

In Funtion TChainHelper.Id add Chain id of that network, i.e., Apothem as 51

For Example

CHAIN_ID: array[TChain] of Integer = (

1,     // Mainnet

51,    // Apothem

...

);

Step 3

In Function TChainHelper.TxType add TX_TYPE as 0

For Example

TX_TYPE: array[TChain] of Byte = (

2, // Mainnet

0, // Apothem
...

);

Step 4

In Function TChainHelper.BlockExplorerURL add Block Explorer Url as 'https://apothemxdcpayrpc.blocksscan.io/' for the Apothem Network

For Example

BLOCK_EXPLORER_URL: array[TChain] of string = (

'https://etherscan.io',                              // Mainnet

'https://apothemxdcpayrpc.blocksscan.io/',           // Apothem

 ...

);

How to copy Transaction hash or Private key ?

After perforning operations output will be on GUI pop-up.

Click on pop-up result and press ctrl-c and paste result on notepad. Then use that result
