Top 15 Smart Contract Development Companies [2023 Selective]

Read this review to compare the top Smart Contract Development Companies, including their services. Understand how the smart contracts work: 

Smart contracts are self-executing computer code and programs that can do certain tasks based on mathematical algorithms and instruction set on code.

Smart contracts were introduced as an idea by American cryptographer Nick Sabo in 1996. They play the role of rule as code-free with the benefits of automating platforms and lessening human control of platforms. They make work easier and cheaper for humans and organizations.

However, in blockchain technology, a major benefit is facilitating decentralized digital transactions among participants to a decentralized or distributed network. The participants can have things accomplished based on a consensus about certain things that govern the network. The transactions are peer-to-peer without a single party controlling or directing.

This tutorial discusses smart contracts and the top companies in developing smart contracts and helps you identify the best contract development company as per your requirement.

How Smart Contracts Work

How smart contracts work

Computer code is written specifying what will be accomplished or not if the conditions agreed upon by the parties to a contract are met or not. They play the role of digitizing manually written and administered contracts, as we know them.

For that reason, they allow the automated exchange of value like digital assets, money, goods like real estate, securities, computer file storage in a distributed network, and other things.

In a blockchain network, smart contracts are overly complex, defining and enforcing the rules under which multiple people can approve a transaction.

For instance, they enable multiple signature protocols that operate in these decentralized networks. Decentralized applications or dApps are based on a set of smart contracts that play together to enforce smart rules that enable the performing of complex transactions.

Market Trends:

  • The global smart contract market size is currently around US$315.1 million and is projected to reach $1.46 billion by 2028.
  • Most blockchain-based smart contracts are built on Ethereum, where over 3000 decentralized applications are hosted currently. However, many other blockchains support them–Cardano, NEO, Stellar, Waves, Hyperledger Fabric, NEM, Polkadot, Solana, Algorand, Ergo, Tezos, Hedera, Tron, etc.

FAQs on Smart Contract Development

Q #1) What are examples of smart contracts? 

Answer: Examples include cryptocurrency trading, voting, lending, borrowing, investing, distributed data storage, etc. For instance, in voting, blockchain smart contracts can validate voters’ identities to prevent multiple casting of votes and hacking to steal elections.

Q #2) Which crypto has smart contracts? 

Answer: Ethereum is the first crypto to use smart contracts. However, cryptocurrencies on Cardano, NEO, Stellar, Waves, Hyperledger Fabric, NEM, Polkadot, Solana, Algorand, Ergo, Tezos, Hedera, Tron, and many other platforms also have smart contracts.

Q #3) Why smart contracts are important? 

Answer: They enable anonymous transactions, speedy execution, and completion of multi-party transactions. They also facilitate secure automation, prevent overindulgence or humans on contracts, and enable cost-effective transactions. They also facilitate the authenticity and credibility of platforms and transactions.

Q #4) What are smart contract platforms? 

Answer: Smart contract platforms are technology systems either blockchains, dApps, or a set of them built by smart contract development companies or developers. They host or facilitate the execution of smart contracts.

These platforms – mostly blockchain – employ smart contracts to facilitate automated trading. They also facilitate other interactions, such as communication and data storage, and other transactions. The platform can itself be a pile of smart contract code or combine smart contracts with other techs.

Q #5) Who writes smart contracts? 

Answer: Smart contract development companies and developers are usually consulted to help conceptualize and write smart contracts. These companies can be experts on a given blockchain or multiple of them. Please check a list of top smart contract development companies on our list.

Q #6) What are smart contracts used for today? 

Answer: They have a vast range of applications, including facilitating the transfer of assets, like in crypto trading between parties. They can be used for inventory management, automation of payments, data storage, initial coin offerings where tokens are distributed after a user pays, betting, escrow in trading, and digital identity.

How Smart Contracts are Designed

The below image shows sample smart contract development life cycle:

sample smart contracts development cycle

Smart contract companies or smart contract development companies hire expert developers who help to design smart contracts from scratch or to customize existing smart contracts.

Usually, smart contract companies follow other development procedures and life cycles used in designing technological applications (see above image). They also entail redevelopment and redesigning as a continuous process. A list of smart contract platforms that follow stringent development life cycles and procedures is available on this list.

Benefits of Smart Contracts

Today, oracles are used to connect non-blockchain platforms to smart contracts on the blockchain. Smart contracts bring the advantages of speedy execution and completion of operations.

  • Independence from third-party interference.
  • Reliability in execution without hacking and tampering.
  • Removal of human errors.
  • Cost-effectiveness by cutting out middlemen.
  • In blockchains, they facilitate micro-transactions between parties. This can happen both locally and across borders and with little interference from any law. They can be used for currency conversion on exchanges, transfer of assets, initial coin offerings, and insurance.


Here are a few disadvantages:

  • Most of these contracts lack regulatory identity.
  • Some are difficult to implement and are overly complex.

Sometimes difficult to change when governed by multiple-party involved in transactions.


Smart contracts based on blockchain help companies to save on cost, reduce manual tasks, and speed operations. They facilitate decentralized ecosystems by reducing interferences on contracts by enabling trustless transactions and interactions.

This tutorial discussed how they work, projected market size, and a list of top smart contract platforms and smart contract development services.

We suggest hiring developers specialized in your specific platform, e.g. Ethereum developers. In addition to the 32 years of experience in smart contracts and other types of development, ScienceSoft has more than 450 developers who develop products across multiple platforms.

Quant and Apriorit are best for cross-platform smart contracts but all the companies on the list are involved in blockchain smart contract development and integration.
