Delphereum: Build Delphi apps that interact with Ethereum

Understand the project

Practical overview

Use Delphereum when developing in Delphi and an application needs to communicate with Ethereum or an EVM-compatible network.

Delphi developers adding Ethereum or EVM-compatible network features to native applications.
Teams building Delphi software that needs to submit transactions, work with smart contracts or read blockchain data.

Before you choose

Compilation requires four companion repositories and their source directories in the Delphi search path.
The README lists no runtime dependencies, while documenting dependencies needed to compile the project.
The project describes broad EVM-compatible network support and names Arbitrum, Optimism, Polygon, Gnosis Chain, BNB Chain, Sonic and PulseChain.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare a Delphi project to compile Delphereum with its documented source dependencies.

Clone the DelphiBigNumbers, SimpleBaseLib4Pascal, HashLib4Pascal, and CryptoLib4Pascal repositories.
Place the repositories alongside the Delphereum directory in the project layout described in the README.
Add the dependency source directories and Delphereum directory to the Delphi search path, using the README’s example path list as a reference.

The Delphi project has the documented dependency repositories and search-path entries needed before compiling Delphereum.

The README documents preparation for compilation, not compilation or application execution.
The example search path assumes the directory layout shown in the README.
