Benefits of Custom Smart Contract Development

There are a number of deliverables smart contracts development will bring into your business. See what will become better and what advantages of Web3 can you leverage.

  • Transparency and Trust

    Complete automation is the premise of smart contracts’ transparency. The smart contract works exactly the way it’s coded, without any centralized parties’ interference. Their execution gives them a competitive advantage compared to other technologies, building trust as no single party can alter the contract without consensus.

  • Speed, Accuracy, and Efficiency

    Smart contracts automatically execute transactions and agreements upon meeting predefined conditions, eliminating manual intervention and reducing the time and potential for errors in executing obligations. Being digital and automated, they suggest no paperwork to complete or time wasted fixing mistakes happening when documents are filled out manually.

  • Stay Secure & Safe

    Hacking a blockchain record is close to impossible; additionally, hackers would need to alter the entire chain to change a single record on a distributed ledger since each record is linked to the ones that came before and after it. Cryptographic security measures make them less prone to fraud or interference, providing a higher level of security compared to traditional contract law.

  • Leverage Decentralization

    Since they run on a blockchain, smart contracts operate in a decentralized environment. This means there's no need for a central authority to manage transactions, reducing potential points of failure and risks of censorship. By enabling secure, transparent, and direct transactions, smart contracts open up possibilities for innovative business models and services that were not possible under traditional contracting mechanisms.

  • Be Modern Yet Compliant

    Smart contracts can be designed to automatically enforce compliance with regulatory requirements and provide an immutable audit trail, simplifying the auditing process: deployed on global blockchain networks, smart contracts provide businesses with the ability to easily execute agreements with international partners without concerns about jurisdictional legal systems and their complexities.

Key Features

Key Features of Custom Smart Contract


Contract Code

The most critical component of a smart contract is its code. This code defines the rules, conditions, and outcomes of the contract in a programming language that the blockchain can interpret. Languages such as Solidity (for Ethereum) are commonly used for writing smart contracts. The code dictates how the contract behaves in different scenarios, including how it initiates transactions, responds to inputs, and reaches its end state.


Data Storage

Smart contracts have their own storage on the blockchain, where they keep state variables and other relevant data. This data could include the contract terms, current status, parties involved, and any other pertinent information required for its execution. The data is immutable and distributed, ensuring integrity and availability.



Functions within a smart contract are blocks of code that are executed when certain conditions are met. These functions can modify the contract's data, trigger transactions, or interact with other contracts. Functions are what make smart contracts "smart" by enabling active management and response to inputs.


Digital Signatures

For a smart contract to be executed, parties involved must consent to the terms, which is typically done through digital signatures. Using cryptographic keys, a participant signs the transaction, which verifies their agreement to the contract's terms and authorizes the contract to execute.


Consensus Mechanism

This isn’t part of the smart contract itself but is crucial for its operation. Blockchain networks use a consensus mechanism to agree on the state of the blockchain and the results of contract executions. This mechanism ensures that the outcome of a smart contract is validated and accepted by the network, making the contract’s execution tamper-proof and irreversible.


Oracles (for external data)

Some smart contracts require information from the outside world (e.g., stock prices, weather data) to execute their terms. Oracles are services that provide this external data to the blockchain in a trustworthy manner. Though not part of the smart contract's code, they are essential for contracts that depend on external triggers.


Event Listeners

Smart contracts can emit events to signal that something has happened (like a condition being met or a transaction being executed). External applications can listen to these events and react accordingly, facilitating interaction between the blockchain and external systems.


Conditional Statements and Control Structures

These programming constructs within the contract code allow the contract to make decisions, loop through operations, and execute based on conditions being met. They are fundamental for the logic that governs contract execution.

Our Process

Our Smart Contract Development Process

Providing excellent blockchain smart contract development services requires work and knowledge. Devox engineers take all the required actions, combining the best practises of SDLC and blockchain development.


01. Requirement Analysis

In smart contract development, initial advisory involves first understanding the business process or agreement that the smart contract will automate or enforce. We then clearly outline the conditions that trigger the contract and the outcomes of those triggers.


02. Design and Prototyping

We decide on the structure of the smart contract, including how it interacts with other contracts and external data sources (oracles). Based on this pattern, our team creates a basic contract version to explore its feasibility and identify potential issues early.


03. Development

Based on the requirements, we select a blockchain platform (e.g., Ethereum, Binance Smart Chain) that supports smart contracts and write the contract code using a blockchain-specific programming language (e.g., Solidity for Ethereum). Devox performs initial tests in a local development environment to catch and fix any obvious bugs.


04. Testing

It’s time to make sure the smart contract works correctly. Starting with Unit Testing (checking individual functions within the contract to ensure they perform as expected), we move on to Integration Testing (testing the contract's interaction with other contracts and systems). Finally, the team deploys the contract on a test blockchain network to simulate real-world operations without risking real assets.


05. Security Audits

Devox performs Static Analysis using tools to analyze the contract's code for known vulnerabilities. Then we hold Peer Review, having other developers outside of the team review the code for security and logic flaws, moving on to professional smart contract audit, conducting a thorough security audit of the contract.


06. Deployment

After thorough testing and auditing, we deploy the contract on the main blockchain network. verify and publish the source code on Blockchain Explorer for transparency and trustworthiness and provide you with comprehensive documentation for the contract, including its functions, usage, and interaction methods.


07. Maintenance and Upgrades

We continuously monitor the contract's performance and interactions to ensure it operates as expected. While smart contracts are immutable, we stay in touch to provide upgrades or fixes through versioning or by designing contracts that can be paused or redirected to updated versions.

  • What is a smart contract and what is it for?

    Smart contract is a blockchain-based computer algorithm that forms, manages or provides information about a digital asset. They are often used to automate the implementation of an agreement so that all parties may be confident of the conclusion right away, without the need for an intermediary or additional delay.

    Smart contracts are used for any kind of operation on the blockchain. On DEXes, they are used in liquidity pools, swaps and staking, while P2E and NFT-gaming utilize smart contracts development to enable more interesting in-game mechanics.

  • What tools and technologies do you use during smart contract development?

    The Devox team develops smart contracts on Ethereum, as well as all the related blockchains (Polygon, Avalanche, Arbitrum, Optimism, Fantom, Binance Smart Chain, Tron, Aurora, xDAI, Gnosis, Harmony, Moonbeam, Moonriver, Metis, Celo, Telos, Velas). We also work with Solana, Polkadot, Ripple, Cardano, Near, Hyperledger Fabric, Hyperledger Sawtooth, ConsenSys Quorum, Hyperledger Besu, and Substrate.

  • How are blockchain and smart contracts connected?

    Blockchain and smart contracts are intrinsically connected, with blockchain serving as the foundational technology enabling smart contracts’ existence and operation.

    Blockchain is a distributed ledger technology that maintains a secure and immutable record of transactions across a network of computers. This technology ensures transparency, security, and decentralization of data. Each block in the chain contains a number of transactions, and once a transaction is recorded, it cannot be altered or deleted, making blockchain a trustless system where parties can transact without needing to know or trust each other.

    Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They run on blockchain networks and automatically execute actions (like transferring funds or recording data) when predetermined conditions are met, without the need for intermediaries.

  • Are smart contracts worth investment and time?

    Investing time and resources in smart contracts can offer significant returns, especially for businesses and industries looking to innovate and optimize their operations, as well as leverage the promise of blockchain. The primary value lies in their ability to automate processes, reduce the need for intermediaries, enhance security, and increase transaction speed. For industries such as finance, real estate, supply chain management, and intellectual property, smart contracts can dramatically streamline operations, cut costs, and open up new avenues for digital interaction that were previously impossible.
