Ethereum Smart Contract Development

Our Indian Smart Contract developers are well-versed in using Solidity to create and test Ethereum-based smart contracts. We can develop ERC-20 and ERC-721 token contracts written in Solidity which can be transferred from one wallet to another ERC-20 compatible address. To do away with the uncertainty of escrow agreements, we can develop digital contracts to issue stablecoins.

Smart Contract for dApps

Decentralized apps (dApps) have their own backend protocol called smart contracts that specify the logic of the entire dApp. We have a well-trained team of developers who are capable of bundling multiple smart contracts into decentralized applications. These applications work together to execute more complex functions. This is how Vofox adds the "smart" in smart contracts. We also develop NFT based games.

Smart Contract Auditing

If you already have a smart contract which you would like to secure, our developers can perform a smart contract audit for data integrity and optimum performance. Based on our auditing methodology, we can identify potential issues in your smart contract, provide you with a detailed report and rectify vulnerabilities, bugs, potential exploits and errors in business logic.

Smart Contract Optimization

Our team can optimize smart contracts before deployment to help clients reduce Ethereum gas consumption. We can implement generic improvements such as short-circuiting, fixed-size byte array, and meaningful use of libraries. We can minimize resource consumption and perform TCO reduction which saves a lot of money for our clients in terms of Ethereum network fee.

Why Choose Smart Contract Development For Business?

Adopting smart contracts will be a smart move for your business. Since encrypted records of transactions are shared across participants and there is no third-party involved, it won't be necessary to question whether information has been changed for personal benefit. Every record in a digital contract is connected to the previous one. A hacker has to alter the entire chain to change a single record in the contract. This kind of technology is the most secure available as of today. This new form of agreement enhances the accuracy and verification of global transactions by combining two simple concepts into one powerful idea.

  • Hack Proof
  • Tamper Proof
  • Traceability
  • Transparency
  • Cuts third-party/middleman
  • Secures your data
  • Reduces transaction time
  • Makes investors trust you

Vofox's fully-functional banking solution leverages smart contracts and DLT (Distributed Ledger Technology) to solve the issue of trust in conditional transactions. We build digital contracts where borrowers and lenders could meet and make self-enforcing agreements with automatic distribution of assets. Advanced payment contracts developed by us make it possible to digitally trade and settle outstanding claims/bills/loans/trades, thereby helping corporate clients implement shorter settlement cycles.


Vofox has successfully developed blockchain-based life settlement solutions that allow real-time policy tracking and transparency in policy sale and purchase. Insurance claims can be paid out automatically when pre-specified criteria are met. Smart contracts improve efficiency across the insurance value chain by automating the entire life settlement process. They minimize fraud, calculate pricing more accurately, and improve the quality of data used during underwriting for insurers and dealers.


A smart contract promises smart health records and smooth payment transactions between healthcare providers and payers. Vofox develops smart contracts that also facilitate the sharing of confidential medical data between hospitals and healthcare centers. It can include test results, vaccine formulas, regulatory compliances, clinical trials, drugs traceability, and healthcare supply management. You can now safely store patients' medical histories in a structured organized manner that can be understood across different institutions.

Frequently Asked Questions

A smart contract is a simple program built using blockchain technology that automatically executes an action when predetermined terms and conditions are met. They work according to “if..then..” statements that are written into code on a blockchain.
In simple terms, a smart contract is a digital contract that runs according to the terms of a contract or an agreement.
As a simple example, consider a contract between an insurer and a farmer. The insurer has to pay the farmer when the temperature falls below an agreed-upon degree. In a traditional agreement, the farmer would have to check the temperature every day, make a claim to the insurer if the temperature drops below a particular degree, and then wait for the insurer to verify the claim and finally pay him. In the case of a smart contract, the insurer will automatically receive a feed of the officially recorded temperature and then automatically initiate payment to the farmer.
