Smart contracts will drive the next revolution in blockchain, says D24 Fintech
Blockchain is set to continue its growth in 2026, with key evolving components and technologies driving it forward. Smart contracts are one such example, quickly becoming the lifeblood of decentralized applications.
“2026 is when smart contracts stop being crypto only and start integrating with real legal, financial, and social systems,” explains Osama Bari, chief technology officer at D24 Fintech. “In 2026, we should see growth in compliance-friendly smart contracts, contracts tied to verified identities, and hybrid on-chain/off-chain logic.”
Back to basics
“For the layman, understanding smart contracts is less about learning code and more about recognizing that trust is no longer confined to human institutions; it is being redefined by code,” continued Bari. “In practice, smart contracts are digital agreements that automatically execute, enforce, or verify the terms of a contract when predefined conditions are met. They reside on a blockchain, which guarantees immutability and decentralization.
“These self-executing lines of code have revolutionized the way we perceive trust, agreements, and digital interactions. For developers, there is work to be done in embracing a new paradigm in how applications behave and enforce logic autonomously.
“In forex trading, for example, a smart contract could auto-execute hedges based on AI signals and real-time price feeds, settling across chains instantly via Layer-2 networks.”
Behind the technology
Bari: “Smart contracts are written in code and stored on blockchain networks, such as Ethereum. Because the terms are embedded directly into the software, the agreement self-executes without relying on a central authority.
“Once deployed, they are nearly impossible to alter, which makes them both secure and transparent. They reduce the need for intermediaries, lower transaction costs, and enable trustless collaboration between unknown parties.
“Common use cases include financial transactions, supply-chain tracking, identity verification, and more. Their decentralized nature ensures that no single party controls the outcome, making them ideal for building transparent and tamper-proof systems.”
What’s the advantage?
Ethereum co-founder Vitalik Buterin described smart contracts as programs that ‘run exactly as programmed without any possibility of downtime, fraud, or third-party interference.’
Bari: “Smart contracts come with four key features that make them perfect for. They’re automated, immutable, transparent, and don’t require input from intermediaries like lawyers or brokers.
“This means that smart contracts can offer benefits in a range of settings from financial services to supply chains, including greater transparency, with every participant able to verify a contract’s logic and outcome via blockchain. In practice, smart contracts could be deployed in scenarios such as within voting systems, ensuring immutability, transparency, and reducing fraud, or even healthcare, securely managing and sharing patient records, and automating insurance payouts.
“It also reduces paperwork, waiting times, and transaction fees paid to intermediaries, like lawyers and auditors, executing as soon as pre-agreed conditions are met. And blockchain immutability means that transactions are secure and almost immune to tampering.”
Looking ahead
Bari: “As the ecosystem matures, smart contracts will become a foundational infrastructure for everything from finance and governance to healthcare and intellectual property. As blockchain technology matures, we’re moving toward adapted applications of smart contracts, like AI-integrated contracts, that are dynamic and adapt to data trends or even regulatory-compliant contracts that automate compliance and tax logic.
“They have the potential to eliminate bureaucracy, prevent fraud, and empower individuals through transparent automation. One thing is clear: smart contracts are not a trend; they are the backbone of the next digital revolution,” concluded Bari.
