Nethereum is an open source .NET integration library for Ethereum. It is designed to help developers easily integrate the Ethereum blockchain into their .NET applications. It consists of modular libraries for features that are covered are writing smart contracts, cryptographic wallets, DApps, and managing blockchain data.

NULS is creating a blockchain coding environment that will be easy to use. NULS wants to make a blockchain development platform that will offer a solution for developing decentralized applications, at a lower cost and with less technical knowledge. The company has teams working in several countries and the platform is powered by the NULS token.
NULLS uses modular smart contracts that are flexible and can be customized for business needs. NULLS provides a coding environment where developers can utilize multi-chain mechanisms, cross-chain consensus, and other technical blockchain features with less technical knowledge.

The XY Oracle Network is a blockchan-based location verification service. It is designed to be compatible with many devices and across different smart contract protocols. XYO uses innovative cryptographic techniques to combine real-world data with a blockchain-based system that can be used by DApps. The XYO Network was developed by a San Diego based company called XY, that makes GPS and Bluetooth devices. The company is building the network's infrastructure that will consist of location-verifying beacons that will enable smart contracts to incorporate location data. The network is powered by the Ethereum-based XYO token.
