A rollout strategy giving an overview of the tech elements and delivery milestones helps us move ahead with implementations confidently.

Smart Contract Optimization

Smart Contract Optimization

Because we have a sound working knowledge of smart contracts and how they can impact businesses, we pay a lot of attention to optimizing smart contract solutions. For example, we verify if-then conditional statements to ensure no gas wastage, short-circuiting, or unnecessary transaction costs.

Ethereum and Hyperledger Smart Contract Development

Ethereum and Hyperledger Smart Contract Development

We can create Solidity smart contracts like ERC-20 and ERC-721 for Ethereum. We can also take care of your requirements around EOS smart contracts and Hyperledger solutions like health wallets, e-warranties, claim settlements, etc., depending on the industry your business caters to.

Digital Wallet Solutions

Digital Wallet Solutions

We have the skills to create digital wallets that need multi-signature authorizations to validate a transaction. For such wallets, our developers encode one, two, or three private keys, depending on the need, to help co-signers approve transactions. By using these keys, we prevent non-authorized sources from seizing accounts.

We get that logic embedded into your Blockchain code to automate your digital contract fulfillment tasks, thus, taking away manual work and human supervision.

Our well-executed manual and automated tests, conducted by our expert QA teams, will give you the peace of mind that your smart contract code is fortified. If needed, we even use open-source security tools depending on the smart contract framework to ensure chances of falsification or forgery are 100% nullified.

Smart Contract for DEX

Smart Contract for DEX

Our experts are aware of the rise of smart contracts for decentralized exchanges (DEXs) that involve no third parties or central authorities for trading. We know the confidentiality of such contracts, which is why we use restrictive functions while writing them to ensure users never lose custody of their crypto wallets while trading.
