Frequently Asked Questions

How do smart contracts work?

A smart contract can be defined as an agreement between two entities in the form of computer code and is executed automatically when certain conditions are met. Smart contracts are based on blockchain technology and stored in a distributed database. A user initiates a transaction via their blockchain wallet. The transaction is verified in the distributed database for identity and is approved or rejected. All transactions are added as blocks within the blockchain. If there is any change in contract status, it follows the process mentioned above to be updated.

Several platforms, including Ethereum, Hyperledger, Counterparty, and Polkadot, allow smart contracts to be developed and executed.

Why are smart contracts important?

Smart contracts are the heart of the blockchain, as they govern the blockchain operation without any need for financial institutions, brokers, or agents. Prescribed coding is used for all purposes, and it facilitates automation and neutrality, reduces transaction costs, and cuts down time. Smart contracts ensure safety and transparency by recording information in every node.

Most cross-border businesses now use smart contracts based on blockchain technology for cross-border payments and transactions. All parties involved in the mortgage process using blockchain smart contracts gain from it. The government can integrate IoT, cloud computing, and blockchain smart contracts to provide best-in-class services to citizens. Healthcare and insurance companies can provide faster services to their clients using smart contracts.

Which cryptocurrencies are best for smart contracts?

Ethereum, Solana, Polkadot, Ergo, Alogorand, and Cardano are the top cryptocurrencies for smart contracts. Ethereum was the first cryptocurrency to come up with smart contract functionality. Solana is the fastest cryptocurrency, with speeds of 50,000 transactions per second (TPS). Polkadot is known for its interoperability, which works well with other platforms. Ergo does not charge gas fees, differentiating it from other cryptos on the list. Alogorand provides scalability, speed, and low costs. Developers can use different programming languages to create smart contracts on Alogorand. On the other hand, Cardano delivers a slow and steady approach to development. These cryptocurrencies are considered to be best for Smart contracts at present.

What are examples of smart contracts?

Smart contracts streamline and increase trade finance by reducing intermediaries and automating several processes. In the finance domain, it can be used for automated payments, document verification, shipment tracking, and dispute resolution. In real estate, it can be used for property transactions, lease agreements, escrow services, and title management. In the healthcare sector, smart contracts allow patient data to be stored securely on a blockchain. Smart contracts can be used in the insurance sector to process claims, automate policy management, and detect fraud.

Smart contracts can not only automate legal processes but also reduce legal fees significantly. In the music industry, it can automate and streamline royalty payments and rights management. Smart contracts are also used for identity verification and management.

What programming languages do smart contract developers use for development?

Smart contracts developers use several programming languages for development purposes, which include Solidity, Rust, JavaScript, Vyper, and Yul. Solidity is a statically typed and object-oriented programming language for creating smart contracts. It is based on C++, Python, and JavaScript and uses similar language structures. Rust is a low-level, statically typed programming language that is fast and memory efficient. JavaScript is a general programming language that is used in blockchain technology.

Vyper targets the Ethereum Virtual Machine (EVM), a Python-like programming language built to address the security issues present in Solidity. Yul is an intermediate programming language designed to address the needs of different backends. It is used in stand-alone mode and for inline assembly in Solidity.

What smart contract platforms do smart contract development companies use?

Smart contract development companies use platforms like Ethereum, Binance Smart Chain (BSC), Cardano, Solana, Polkadot, Avalanche, and Tezos. Ethereum is a versatile platform for blockchain and a good choice for developers who want to build innovative apps. Cardano is a blockchain platform that is known for sustainability and scalability. It uses a layered architecture for greater scalability. Solana can process many transactions per second and uses a proof-of-history consensus mechanism. Polkadot allows interoperability between different blockchains, which allows a truly decentralized ecosystem and user-friendly experience. Avalanche is versatile, scalable, and uses a proof-of-stake consensus protocol and shared ledger. Tezos has a growing ecosystem of dApps and uses a unique proof-of-stake consensus mechanism.

Are smart contracts written mostly by blockchain developers or companies?

A developer can program smart contracts, although organizations that use blockchain for business provide online tools, web interfaces, and templates to simplify the creation of smart contracts. Smart contracts execute simple “if/when…then…” statements written into code on the blockchain. The actions are executed on a network of computers when certain pre-defined conditions are satisfied.

These actions include funds, ticket issuing, registering a vehicle, or sending notifications. Once the transaction is complete, the blockchain is updated. No one can change it; anyone granted access can see the results. Smart Contracts have as many conditions as are required to perform the task satisfactorily.

What industries can benefit from smart contract development?

Several industries can benefit from smart contract development, which includes healthcare, retail, eCommerce, financial services, human resources, and real estate. Blockchain provides a fast and secure way to share patient information, and hospitals can use smart contracts to share patient data with insurance providers. Brick-and-mortar and online stores can use smart contracts to streamline their back-end processes. The financial services industry can use smart contracts for payments and claim settlements.

Smart contracts have lots of potential for human resources professionals. They execute their back-end work and allow them to focus on scrutiny and selection. Real estate provides a wide range of applications for smart contracts, including mortgages, recording credit scores, property transfers, and preventing missed payments.

What is the process of smart contract development?

The process of smart contract development starts with defining the requirements. It is followed by designing, coding, testing, and deployment. The development team contacts the client or internal stakeholders to discuss the requirements and objectives. Based on these discussions, the development team designs smart contract architecture and aligns everything with the goals.

The next step is for developers to write the logic using programming languages such as Solidity. Once the code is written, simulations are performed for various scenarios to ensure the smart contract behaves as it should. This includes unit testing, integration testing, and security checks. Finally, a smart contract is deployed and assigned an address.

How do I hire a smart contract development company?

How much does smart contract development cost?

The cost of smart contract development depends on the level of complexity, the workforce involved, business needs, and the tech stack. The complexity of the project will vary with every new set of requirements. Your smart contract should follow the coding standards; otherwise, maintenance and post-deployment will cost extra money. Complex projects require more development hours, and the cost increases with additional hours.

The tech stack used for smart contract development increases or decreases the overall cost. It can be Ethereum, Hyperledger, Truffle, or other platforms. The more advanced the technology, the costlier it will be. For an estimate, the cost can be between $7,000 and $70,000.
