Smart contracts offer new opportunities for automation, efficiency, and transparency in financial services—an industry traditionally dependent on manual processes and intermediaries. As self-executing agreements with terms directly encoded into software, smart contracts “automatically enforce and execute these terms when predefined conditions are met,” as Forbes describes.
For hedge funds, alternative asset managers, and other financial services firms, understanding and implementing smart contract technology can be a critical competitive advantage in the industry’s digital marketplace. This article explores smart contracts as a concept and opportunity, with recommendations about how financial firms can use smart contracts in their operations.
Understanding Smart Contracts: Beyond the Hype
Gartner defines a smart contract as “a type of blockchain record that contains externally written code, and controls blockchain-based digital assets.” A user writes to the blockchain, causing the smart contract to execute its code immutably—this may trigger another blockchain event, and so on, until a predetermined process is complete.
It’s important to note that they are not literal “contracts.” Humans must manage official agreements externally, acting based on trusted “on-chain” events and engaging in formal “off-chain” behaviors.
In other words, while smart contracts can automate many processes, successful implementation in financial services requires sophisticated integration with existing infrastructure and careful orchestration of data flows between legacy systems, individuals, and blockchain networks.
Smart contracts, therefore, can reinforce agreements. According to IBM, the technology works through an executable code “ that runs on top of the blockchain to facilitate and enforce an agreement between untrusted parties without the involvement of a trusted third party.” The two untrusted parties can guarantee that some agreed-upon requirements are met through the trust and verification of a blockchain network. This protects the integrity of agreements and transactions.
The Growth of Smart Contracts Among Financial Firms
The smart contracts market is experiencing rapid expansion, projected to hit $73 billion by 2030 and growing at 82.2% CAGR. 2025 is shaping up to be a pivotal year, with adoption accelerated by major institutional players entering the space, World Economic Forum reports. For example, fintech leaders like PayPal are embracing blockchain and developing new crypto-powered solutions, underlining the technology’s practical value for the financial sector.
Smart contracts dramatically reduce reliance on intermediaries, automating agreement enforcement and enabling near-instant, low-cost execution compared to traditional processes. By streamlining digital asset and payment flows, financial firms can unlock new products and business models while significantly lowering operational costs and decreasing dependence on legacy post-trade infrastructure.
Automated Portfolio Rebalancing
Smart contracts excel at supporting rules-based portfolio management strategies. When integrated with price feeds and portfolio monitoring systems, smart contracts can automatically execute rebalancing trades when predetermined thresholds are breached. This automation eliminates the delay and potential errors associated with manual rebalancing processes while ensuring consistent adherence to investment mandates.
Trade Settlement and Clearing
Trade settlement is especially impacted by smart contracts in financial operations. Financial firms can eliminate unnecessary intermediaries, simplifying multi-party workflows and enabling highly reliable transactions executed directly on the blockchain. Automation of delivery-versus-payment (DvP) processes can accelerate settlement times, reducing the typical lag of a T+2 cycle to almost real-time execution, improving efficiency and reducing counterparty risk.
Compliance and Regulatory Reporting
Smart contracts allow financial firms to automate compliance by embedding rules into transaction logic, instantly producing audit trails and reports. This boosts accuracy and real-time verification across financial operations, making smart contracts a trusted choice for streamlining transparency and regulatory adherence in digital finance.
Treasury Management and Cash Optimization
For firms managing multiple cash accounts across various institutions, smart contracts can automate cash sweeps, optimize yield by automatically moving funds to higher-yielding instruments, and manage liquidity requirements across different time horizons.
Security Architecture: Building Robust Foundations to Support Smart Contracts
For financial institutions deploying smart contracts, a multi-layered security approach can ensure safe and reliable operations. Here are several core practices widely recommended by industry leaders and research authorities.
- Comprehensive Code Review: All smart contract code should undergo meticulous review by independent security experts prior to deployment. External audits and peer assessments are highly effective for detecting logic errors or security weaknesses that could be exploited.
- Formal Verification Techniques: Employ mathematical methods to verify that smart contracts perform as intended under all possible scenarios. This process, often used in critical financial applications, helps prevent unexpected outcomes and demonstrates that the contract’s logic is fundamentally sound.
- Community-Driven Vulnerability Reporting: Establishing programs that reward ethical hackers and external researchers for discovering potential weaknesses can strengthen defenses. Engaging a broad security community encourages proactive identification of issues before they are exploited.
- Ongoing Maintenance and Updates: Smart contracts and underlying protocols must be routinely maintained. Regularly updating contract code to respond to emerging threats helps safeguard against newly discovered vulnerabilities and keeps systems resilient to evolving attack methods.
Implementing these practices, alongside vigilant monitoring and multi-factor controls, forms a robust foundation for the secure integration of smart contracts in financial operations.
Risk Management: Understanding the Challenges of Smart Contracts
Despite their advantages—and like any technical solution—smart contracts infrastructure also comes with risks. Here, we consider how those risks could impact your organization and how they have already impacted others.
Technical Risks
Smart contracts demand highly precise coding and secure blockchain infrastructure, as even minor programming errors can lead to severe consequences, such as unauthorized transactions or loss of funds. Past incidents—like the 2016 DAO flaw that resulted in a major security breach and significant financial loss—highlight the critical importance of rigorous development and auditing.
Economic and Market Risks
Sudden market shifts and volatility can test the limits of automated smart contract systems. If conditions change abruptly, as seen in previous market crashes, smart contracts may fail to adapt in real time, exposing users to unexpected losses or system failures. Periods of heavy network usage can slow down transaction processing and increase operational costs, underscoring the need for robust scalability planning.
Legal and Regulatory Uncertainty
Navigating the legal landscape remains challenging, as regulations governing smart contracts vary widely across jurisdictions and are often not aligned with traditional contract law. What is permissible in one country may violate rules in another, and legislative changes can introduce new complexities or disrupt blockchain projects with little notice. This ongoing uncertainty makes it essential for firms to continuously monitor and adapt to evolving legal requirements when leveraging smart contract technology.
Regulatory Compliance: Navigating Smart Contracts and Financial Regulations
FINRA Requirements and Guidance
The Financial Industry Regulatory Authority (FINRA) has significantly increased its focus on crypto asset securities, issuing detailed guidance that directly impacts how financial firms must approach smart contract implementation. For example, FINRA’s 2024 Annual Regulatory Oversight Report includes specific content about smart contracts in terms of transparency with customers.
Key compliance requirements include:
- Membership Application Clarity: Firms must clearly outline all aspects of their planned crypto asset activities within their FINRA membership application. This ensures regulators have a comprehensive understanding of the firm’s business model and intended operations related to crypto assets.
- Documented Policies and Procedures: Broker-dealers should maintain and regularly update detailed internal policies, controls, and procedures that specifically cover the unique risks and requirements associated with crypto assets, such as due diligence, trading practices, custody arrangements, and legal compliance.
- Anti-Money Laundering Preparedness: Firms are expected to integrate crypto asset considerations into their anti-money laundering (AML) programs, ensuring that processes are in place for monitoring and detecting suspicious activity involving digital assets.
- Robust Cybersecurity Measures: Dealers offering crypto services must assess and fortify their cybersecurity protections to address potential vulnerabilities associated with digital asset platforms and transactions.
- Transaction and Communication Monitoring: Adequate systems should be in place to monitor crypto asset transactions and to oversee communications with customers, helping to ensure both regulatory compliance and customer protection
It’s worth noting that FINRA’s examination of customer communications revealed significant compliance gaps. The results of FINRA’s targeted analysis about customer communications found potential violations of its public communications Rule 2210 among roughly 70% of organizations involved in the study, Hunton found.
A Phased Approach to Implementing Smart Contracts
A step-by-step roadmap helps financial firms integrate smart contracts effectively while addressing critical issues of compliance, market exposure, and technical resilience. The following progression ensures a disciplined transition from initial planning to enterprise-wide adoption.
