Smart contract development services & implementation best practices
A smart contract is a digital protocol that automatically executes itself when conditions specified in its code are met, eliminating the need for a middleman. Smart contracts are typically deployed on a blockchain, which provides them with a decentralized environment for execution.
Whether it’s an asset exchange, a crowdsourcing campaign, or an insurance platform, Itransition provides comprehensive blockchain services to help you achieve a new level of automation and transparency for your operations.
How a smart contract works
A smart contract operates by following the 'if-then' principle. If the predefined rules outlined in a smart contract code are met, then the agreement is automatically enforced. For example, a smart contract in insurance can be programmed to automatically transfer funds to an insured party if a triggering event occurs, such as a flight cancellation or a shipping delay. This eliminates the need for a third party to confirm that a specific event happened and makes the process more transparent.
Setup
Establish contract terms for all stakeholders
Embed conditions in the code
Events
Off-chain event (flight cancellation) or on-chain event (fund transfer) triggers contract execution
Execution
Smart contract executes based on predefined conditions
All stakeholders involved receive a notification with details of the action taken
Settlement
Digital assets (crypto, tokens) automatically settle in a blockchain-based wallet
Off-the-chain assets (fiat currencies) settle through a payment gateway

Smart contract use cases by industries
Finance
DeFi
Blockchain-based smart contracts can help financial organizations automate financial services delivery and eliminate intermediaries. With smart contracts in place, lending, borrowing, and trading become transparent and significantly less prone to counterparty risk.
AML & KYC compliance
Financial institutions can use smart contracts to automate compliance checks, get rid of resource-intensive conventional verification methods, and securely share sensitive customer information within a trusted network of participants.
Asset tokenization
Smart contracts can be used to tokenize illiquid assets like real estate, artwork, and venture capital funds. This allows investors to purchase fractions of these assets on a digital exchange with lower fees.
Asset and investment management
Smart contracts can transform asset and investment management by making it more transparent than ever before. With the help of DAO, fund managers can quickly attract investments via IDO/ICO, while investors can provide capital under clear conditions that can be easily verified by the blockchain.
Insurance
Parametric insurance
Smart contracts can automatically execute payouts to policyholders based on off-chain information like weather conditions and seismic activity. For example, if a farmer’s crop fails due to a flood, the smart contract can automatically trigger a payout when rainfall surpasses a specified threshold.
Reinsurance
By tokenizing reinsurance policies as smart contracts and having a tamper-proof record of all claims on the blockchain, insurance companies can drastically decrease the amount of paperwork.
Claim processing automation
By using the abundance of data collected from IoT sensors, wearables, governmental databases, authoritative international organizations, and other reliable data providers, insurance companies can program smart contracts that automatically process life, car, flight, home, and health insurance claims.
Supply chain
Assets tracking
With the help of smart contracts, IoT sensors, and RFID tags, supply chain companies can securely share real-time information about their assets’ movements with each other. This ensures trust between all stakeholders, enhances transparency and reduces delays caused by manual recordkeeping.
Product safety
Supply chain organizations widely use IoT sensors to check if products in transit are kept at an agreed temperature, moisture level, etc. Smart contracts can be programmed to automatically issue payouts if certain parameters deviate from agreed thresholds.
Utilities
P2P energy trading
Blockchain, smart contracts, and tokenization are the main enablers of peer-to-peer energy trading and grid decentralization. Smart contracts can automatically handle payment processing and offer energy to other participants when a surplus is generated. This network typically includes individuals and households, industrial businesses, and sometimes energy retailers.
Billing automation
Smart contracts can facilitate billing automation by integrating with IoT-enabled metering systems. Predefined embedded pricing algorithms can automatically calculate bills, which smart contracts can issue to consumers.
Healthcare
Drug supply chain tracking
Smart contracts can be used to track pharmaceuticals along the supply chain, authenticate drugs by verifying their origin, and ensure that the drugs were maintained properly during transfer. This drastically reduces the risk of counterfeit medicines and ensures that they are safe to use.
Patient data management
Smart contracts allow healthcare institutions to share confidential data while maintaining patient anonymity, significantly enhancing the security of sensitive information and simplifying regulatory compliance for clinical trials.

2
Technical analysis
After thorough analysis, we conduct a technical overview of your project and select the blockchain platform to support your smart contracts.
3
Architectural design
We determine which modules should be implemented off-chain and on-chain, evaluate the need for oracle integration, decide between microservices and monolithic structure, outline call points, and build relevant APIs.
4
Development
At this stage, we connect the dots to define your smart contract functionality, write the code, and deploy it to a public testnet.
5
Smart contract security audit
Further, we ensure bug-free performance and optimal resource consumption by smart contracts, as well as validate their immunity to cyber threats.
6
Deployment
In the final stage, we deploy smart contracts to the live network. As your project grows, it will be possible to add new features, as our smart contract design is flexible and adaptive. This may include integrating new APIs or facilitating tokenization (NFT).

FAQs
How much does smart contract development cost?
The cost of a smart contract depends on the complexity of the embedded business logic and the platform it’s running on. Apart from these two main factors, the price of smart contract development can vary based on the number of security audits and maintenance updates it requires in a particular industry.
What is an example of a smart contract?
In logistics, for example, a smart contract integrated with an IoT system can automatically check the quality of products in transit by verifying that the product is kept at an agreed temperature range. If the temperature goes above or below certain thresholds, the smart contract can automatically issue money to the relevant stakeholders.
What is a smart contract vs blockchain?
Blockchain is a distributed ledger that records transactions, including those related to cryptocurrencies. Smart contracts are self-executing programs that are stored on a blockchain. Essentially, smart contracts leverage blockchain’s decentralized nature and inherent immutability.
