Ethereum Application Development Company

What is Ethereum?

Ethereum is an open-source Blockchain-based distributed computing platform and operating system featuring smart contracts functionality. It was the first blockchain project to install smart contract technology, which eliminates the need for third party to enter into an agreement. Compared to other Blockchain platforms, over Ethereum you can do programming, and developers can use it to develop many new kinds of applications. Nevertheless, it was the first Blockchain to include a programming language. On Ethereum, we can write code that controls digital value, runs exactly as programmed, and is accessible anywhere in the world. Ethereum also has its cryptocurrency named Ether. Very much similar to Bitcoin, Ethereum allows one to send and receive coins between wallets​

Blockchain development platforms we work on


Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing, and Technology.


Ethereum is an open-source blockchain-based distributed computing platform and operating system featuring smart contracts functionality. Ethereum was the first blockchain project to install smart contract technology, which eliminates the need for third party to enter into an agreement


Corda is an open source blockchain project, designed for business from the start. Only Corda allows you to build interoperable blockchain networks that transact in strict privacy. Corda's smart contract technology allows businesses to transact directly, with value.


Hashgraph is a distributed ledger technology. It is an asynchronous Byzantine Fault Tolerance consensus algorithm capable of securing the platform against attacks.


EOS is a Blockchain platform which is powered by native cryptocurrency named as EOS. Its is a decentralized operating system which can support industrial large-scale dApps.


Stellar is an open source network for financial products, with Stellar one can create, send and trade over digital assets.


Tezos is a platform linked to a digital token, called a Tezzie or Tez, which is a decentralized blockchain platform that is self-governing and establishes a true digital commonwealth. Here token holders get a reward for participating in the proof-of-stake consensus mechanism, as platform is not based on the mining of Tez. Tezos is a smart contract and dApp platform. What makes it unique from other platforms is its self-amending cryptographic mechanism.

Advantages of Ethereum Development

Having more than 2+ years of cumulative experience developing  Ethereum Applications on different platforms, we understand you requirement better than else and capable of delivering at lightening speed. Hire Ethereum Application Developers as per your requirement from leading tech company.

Data co-ordination

The decentralized architecture of Ethereum allocates information and trust so that network participants do not have torely on a central entity to manage the system and mediate transactions

Rapid deployment

Enterprises can easily deploy and manage private blockchain networks instead of coding a blockchain implementation from scratch with SaaS platform

Permissioned networks

Ethereum enables businesses to build on public or private Ethereum networks, thereby ensuring that your solution fits any potential regulatory and security requirements

Private transactions

Ethereumallows the forming private consortia with private transaction layers and such private data is encrypted and onlyshared directly with relevant parties

Network size

Ethereum network can work with hundreds of nodes and millions of users and mainnet proves it. Network size is very critical in current time.

Scalability and Performance

Ethereum can outperform the public mainnet with Proof of Authority consensus, custom block time and scale up to hundreds of transactions per second or more depending on network configuration


It offers customizable consensus mechanisms including RAFT and IBFT for different enterprise network instances, which ensures immediate transaction finality and reducing the required infrastructure that the Proof of Work algorithm demands


Over Ethereum businesses can tokenize any asset, which had been registered in digital format


In Ethereum there is standardization in decentralized storage, decentralized messaging and protocols around token design so that the ecosystem is not balkanizing

Inter-operability and Open source

Ethereum based consortium is notlocked into any of the vendor’s IT environment and hence is inter-operable.

With the advancement of DApps on the Ethereum blockchain network, it ensures permanency, transparency & complete security to all electronic business transactions. Thus, allowing us to leverage numerous advantages from Ethereumblockchain development in case your business is scalable and will help achieve increase the reach exponentially​

Tools which we use in Ethereum development Truffle

To test Ethereum Smart Contracts and to deploy custom applications for both private and public networks, we use Truffle


Remix IDE is used to build, deploy and test smart contracts written in Solidity programming languages by our Ethereum Application Development Team


With Ganache we test local test nodes, to test the interaction of smart contracts and to deploy contracts


Using Embark, we build custom Ethereum apps as it offers modularity in developing, testing and deploying smart contracts. Service monitoring, real-time deployment and interactive REPL are some of the tools provided in Embark


To build Ethereum based apps, connect independent blockchains, enable smart contracts permissioning on public blockchains, we use Parity Tools like Parity Ethereum, Polkadot, Substrate, Secret Store and Bridge


Zeppelin tools are being used to manage reusable smart contracts and perform security audit checks on smart contracts, by our Ethereum App Development Team

What is ethereum used for?

What Is Ethereum. Launched in 2015, Ethereum is an open-source, blockchain-based, decentralized software platform used for its own cryptocurrency, ether. It enables SmartContracts and Distributed Applications (ĐApps) to be built and run without any downtime, fraud, control, or interference from a third party.

What is Enterprise Blockchain
Enterprise Blockchain Developers In India

Is ethereum worth buying?

Due to the fact that many ICOs intend to release their own tokens on the Ethereum network in the coming months, many expect to see Ethereum rise back up to its all-time high value and even pass it. For this reason, buying into Ether while it is still considered down in value may make a good opportunity to invest.

Frequently Asked Questions

According to him, Bitcoin and Ethereum will each hold 25 per cent of the entire crypto industry, which he predicts to reach a total market cap of $4.5trn in 2020. For his prediction to come true, the ETH’s value should rise by over 700 per cent

Bitcoin has a lower coin supply and is more liquid than Ethereum, but Ethereum has better technology and provides more uses than Bitcoin does. Based on the fact Ethereum has more use cases than Bitcoin — and therefore serves a bigger purpose — I can say that it is indeed an overall better Bitcoin alternative.
