Citi’s Solana Breakthrough may offer a timely answer to these issues. In recent industry discussions, Citi’s Solana Breakthrough has been highlighted as an innovative solution to these systemic problems. This antiquated framework burdens businesses with reduced liquidity, increased costs, and heightened risks, making innovation not just an option but an imperative for survival in a volatile global economy.
Enter a groundbreaking collaboration poised to redefine the future of trade finance. Citi, a global banking giant, in partnership with blockchain innovator Solana and consulting firm PwC, has embarked on a pioneering journey to tokenise bills of exchange. This initiative isn’t just an experiment; it’s a strategic move to leverage blockchain technology to slash costs, dramatically boost speed, and drive unprecedented efficiency in on-chain finance. This article serves as a definitive guide for financial executives, trade finance professionals, and blockchain strategists, offering practical, expert-backed insights into how this powerful partnership is laying the foundation for a new era of digital trade. We will explore the enduring problems with traditional trade finance, unpack the specifics of Citi’s tokenisation proof of concept, highlight Solana’s crucial role as an institutional-grade infrastructure, and examine the broader implications for real-world asset (RWA) tokenisation and the future of global supply chains.
The Bottlenecks of Traditional Trade Finance: Why Innovation is Imperative
The mechanics of global trade have, for centuries, relied on established yet often cumbersome processes. While robust, these traditional methods are increasingly struggling to keep pace with the demands of a fast-evolving, interconnected world. Businesses navigating international commerce face significant hurdles, from operational complexity to financial risk, underscoring the urgent need for transformative solutions. These global trade disruptions and traditional trade finance problems impede supply chain financing and make the issuance of bills of exchange particularly painful.
According to Citi’s 2026 Supply Chain Financing report, the global trade landscape is continuously challenged by tariffs, geopolitical tensions, and macro shocks, which underscore the need for resilient and efficient financial mechanisms [1]. The report emphasises that while supply chains have adapted, “emerging technology [is] keeping them competitive by lowering costs and improving speed” [1]. This sentiment perfectly encapsulates why blockchain-based solutions are becoming not just attractive, but critical.
Understanding Bills of Exchange (BoE) and Their Complex Journey
A bill of exchange is, at its core, a written order from one party (the drawer) to another (the drawee) to pay a specified sum of money to a third party (the payee) at a future date or on demand. These trade finance instruments have been instrumental in facilitating international trade for hundreds of years, offering a way to extend credit and manage payment obligations across borders.
However, the traditional BoE process is notoriously multi-step and often paper-based, leading to significant friction. It typically involves:
- Issuance: The seller (drawer) creates the bill, often requiring bank involvement for authentication.
- Acceptance: The buyer (drawee) or their bank accepts the bill, committing to payment. This often involves physical documents being couriered.
- Financing: The seller may discount the bill with a bank or financier to receive funds early, often involving further paperwork and due diligence.
- Distribution/Transfer: The bill can be traded or transferred multiple times before maturity, each transfer potentially adding layers of intermediaries and paperwork.
- Settlement: At maturity, the drawee makes the payment, and funds are disbursed, often through traditional banking rails, which can take days to clear internationally.
Each of these steps introduces potential delays, administrative overhead, and opportunities for error, making the bills of exchange definition and their subsequent journey a testament to legacy systems.
The Economic Toll of Inefficiency in Global Supply Chains
The complexities inherent in traditional trade finance instruments carry a substantial economic toll. The reliance on manual processes, multiple intermediaries, and protracted settlement times translates directly into increased operational costs for businesses engaged in global trade inefficiencies. This not only eats into profit margins but also significantly ties up working capital, leading to reduced liquidity across the supply chain.
Moreover, these inefficiencies heighten trade finance risks. The lack of real-time transparency makes it harder to track the status of bills and can lead to disputes or fraudulent activities. Delays in payment and settlement can disrupt cash flow, particularly for small and medium-sized enterprises (SMEs) that depend on timely access to funds. The overall impact is a hindrance to timely settlements and, consequently, to business growth and competitiveness on a global scale. The Citi report highlights that the adoption of “blockchain and AI” is pivotal for businesses to “lower costs and improve speed,” emphasising the transformative potential of these technologies in overcoming these traditional hurdles [1].
Citi, Solana, & PwC: Pioneering the Tokenisation of Bills of Exchange
In a significant move poised to reshape global trade finance, Citi has announced a groundbreaking collaboration with the Solana Foundation and PwC. This partnership represents a concerted effort to address the traditional trade finance problems through blockchain bills of exchange, specifically by tokenising these critical financial instruments. The initiative aims to leverage the power of distributed ledger technology to create a more efficient, transparent, and cost-effective ecosystem for Citi on-chain finance.
The central goal of this collaboration is to demonstrate the practical viability of tokenising a bill of exchange, executing its entire lifecycle on a blockchain. This proof of concept (PoC) directly addresses the core user question: “How does Citi use Solana for tokenisation?”
Citi explicitly stated, “Working with PwC and Solana, Citi has completed an internal proof of concept (PoC) that represented a bill of exchange as a token on a blockchain and executed the entire lifecycle – issuance, financing, distribution, and settlement – in a simulated environment” [1]. It’s important to note the nuance here: while Citi refers to this as a “proof-of-concept stage,” some reports, including a statement from Solana on X (formerly Twitter), have suggested the “product is live” [6]. This distinction likely pertains to the internal, simulated nature of Citi’s PoC versus the broader potential and readiness of Solana’s infrastructure for such applications.
The Proof of Concept: Executing the Entire BoE Lifecycle Onchain
The Citi blockchain PoC centred on demonstrating that a tokenised bills of exchange lifecycle can be managed entirely on-chain, bypassing many of the manual and intermediary-heavy steps of traditional processes. In the simulated environment, Citi, with the technical expertise of Solana and the strategic guidance of PwC, successfully replicated and streamlined the four critical phases:
- Issuance: Instead of physical documents, a digital representation of the bill of exchange was created as a token on the Solana blockchain. This token contained all relevant details of the underlying financial instrument, secured by cryptographic principles.
- Financing: The tokenised bill could then be instantly offered for financing to a network of approved participants. The blockchain’s inherent transparency and immutability facilitated rapid due diligence and secure, near-instantaneous financing transactions.
- Distribution: The ownership of the tokenised bill could be transferred seamlessly between parties, eliminating the need for physical delivery or complex legal agreements for each transfer. This enables faster secondary market liquidity.
- Settlement: Upon the bill’s maturity, the settlement of funds could be executed programmatically through smart contracts, ensuring automatic and immediate payment to the rightful owner of the token. This significantly reduces settlement risk and time.
By moving these processes on-chain, the PoC illustrated a pathway to drastically cut down on processing times, reduce human error, and enhance the overall integrity of the trade finance ecosystem.
Tangible Benefits: Easier, Faster, and Cheaper Trade Finance
The tokenised bills of exchange lifecycle demonstrated by Citi, Solana, and PwC promises a range of tangible benefits that directly address the pain points of traditional trade finance problems. By leveraging blockchain technology, this innovation aims to deliver streamlined trade finance that is fundamentally easier, faster, and cheaper.
Key advantages include:
- Cost Reduction: Automating manual processes, reducing reliance on intermediaries, and minimising paperwork leads to significant cost reduction through blockchain implementation. Each transaction becomes less expensive to execute and manage.
- Increased Speed: Transactions that traditionally take days or weeks can be completed in minutes or hours. The instantaneous nature of blockchain settlements accelerates cash flow, improving liquidity for all parties involved.
- Enhanced Transparency: Every step of the bill’s lifecycle, from issuance to settlement, is recorded on an immutable ledger, providing an auditable trail that improves trust and reduces the potential for fraud. Participants have real-time visibility into the status of their transactions.
- Mitigated Risk: The immutability of blockchain records and the automation of smart contracts reduce operational risks associated with human error, document loss, and payment delays. Fraudulent activities become much harder to execute.
- Improved Accessibility: Tokenisation can potentially lower the barrier to entry for smaller businesses to access trade finance by making the instruments more liquid and discoverable to a broader pool of financiers.
As highlighted in the Citi report, the integration of blockchain technology and artificial intelligence is specifically aimed at helping businesses “lower costs and improve speed” in their global trade operations [1]. This PoC validates that tokenisation is a powerful tool to achieve these critical objectives, directly answering the question: “What are the benefits of tokenising bills of exchange?”
Solana’s Advantage: The Engine for Institutional-Grade Onchain Finance
The choice of Solana as the blockchain infrastructure for Citi’s pioneering proof of concept is not arbitrary. It speaks volumes about the network’s capabilities and its growing appeal for institutional adoption. This section explores why the Solana blockchain stands out as financial infrastructure for the internet, addressing the question: “What is the role of Solana in traditional finance?
Lily Liu, President of the Solana Foundation, succinctly captures this vision, stating, “Bitcoin is the asset. Solana is the infrastructure. It’s financial infrastructure for the internet” [2]. This positioning underscores Solana’s ambition to be the high-performance backbone for a new era of digital finance. The network’s architectural design prioritises speed, scalability, and cost-efficiency—qualities that are non-negotiable for Solana enterprise blockchain solutions.

Beyond raw performance, Solana security and blockchain reliability are critical factors for traditional financial institutions considering integrating blockchain into their core operations. For a bank like Citi, the integrity and trustworthiness of the underlying network are non-negotiable.
Solana employs a robust proof-of-stake consensus mechanism that incentivises validators to act honestly and secure the network. While no system is entirely immune to challenges, Solana’s architecture incorporates features designed to maintain network uptime and prevent malicious attacks. Its rapidly expanding ecosystem of validators and continuous development efforts contribute to its overall resilience. This commitment to security and consistent uptime helps build institutional trust, allowing major players to confidently explore and deploy Solana enterprise solutions. The network’s capacity to handle high-value transactions with cryptographic security provides the necessary confidence for the widespread adoption of tokenised assets in Solana in traditional finance.
The Broader Impact: Real-World Asset (RWA) Tokenisation & Global Supply Chains
Citi’s proof of concept with Solana and PwC is not an isolated event; it’s a significant milestone within the burgeoning trend of real-world assets tokenisation. This section expands on the profound significance of this PoC, particularly within the context of Solana’s emergence as a dominant platform for tokenised assets. It addresses “What is the current state of tokenised real-world assets on Solana?” and explores “Which other companies are using Solana for enterprise solutions?”
The tokenisation of real-world assets (RWAs) refers to the process of representing tangible and intangible assets on a blockchain, turning them into digital tokens. This concept extends far beyond bills of exchange, encompassing everything from real estate and commodities to intellectual property and carbon credits. The market for tokenised real-world assets on Solana has seen remarkable growth, with its record reaching an impressive $873 million at the start of the year [3]. This substantial figure underscores the network’s increasing traction as a preferred platform for institutional-grade RWA projects.
Beyond the specific case of bills of exchange, a growing number of major corporations and Wall Street firms are actively exploring or building on Solana, further cementing its role in global trade tokenisation and Solana institutional adoption.
The Rise of Tokenised Real-World Assets on Solana
RWA tokenization explained simply, means creating a digital, programmable version of an asset that lives on a blockchain. This process unlocks unprecedented liquidity, fractional ownership, and transparent, immutable record-keeping. Solana’s high throughput, low transaction costs, and robust developer ecosystem make it particularly well-suited for facilitating this transformation across diverse industries.
For example, real estate tokenisation allows investors to own a fractional share of a property, lowering investment barriers and increasing market liquidity. Similarly, tokenising commodities can streamline trading and settlement. Solana’s ability to handle these complex transactions at scale with minimal fees positions it as a leader in the future of asset tokenisation. The network’s established Solana RWA projects are demonstrating the practical applications and immense potential, as evidenced by the $873 million record for tokenised real-world assets [3]. This figure is a clear indicator of the market’s confidence in Solana’s infrastructure for these high-value, enterprise-level applications.

A prime example is Alibaba, which has invested in developing infrastructure to speed up Solana RPC nodes [4]. This move by a global e-commerce and technology giant signifies a strong vote of confidence in Solana’s underlying technology and its potential for enterprise-level applications, from supply chain management to digital payments. Furthermore, WisdomTree, a prominent asset manager, has expanded access to the Solana network [5]. This integration by a traditional finance player illustrates the broadening acceptance of Solana as a legitimate and high-performing blockchain for accessing digital assets and implementing tokenised assets on Solana. These developments highlight Solana’s trajectory toward becoming a foundational layer for various business operations, moving far beyond bills of exchange and into the fabric of global commerce.
The Road Ahead: Challenges, Regulation, and the Future of Onchain Finance
While the tokenisation of bills of exchange by Citi, Solana, and PwC marks a significant leap forward, the journey towards widespread adoption of tokenised financial instruments is still in its early stages. This final section explores the critical challenges that lie ahead, particularly concerning regulatory frameworks, and outlines the scalability plans crucial for the future of tokenised finance. It addresses questions like “What is the future outlook for tokenised real-world assets?” and delves into the global trade blockchain outlook.
Citi’s initiatives, including this PoC, are part of a broader strategic vision for “on-chain finance” [1]. This involves a comprehensive digital transformation within traditional banking, moving more financial processes and assets onto blockchain networks to unlock greater efficiency, transparency, and new business models. This ambition requires not only technological advancements but also substantial collaboration across industries and with regulatory bodies.
Navigating the Regulatory Landscape for Tokenised Instruments
One of the most pressing challenges for the future of tokenised finance is the evolving tokenisation legal framework. The nature of blockchain technology—its borderless operation, immutable records, and programmable features—presents unique complexities for existing financial instrument regulation. Regulators worldwide are grappling with how to classify and oversee these new digital assets, ensuring market stability, investor protection, and compliance with anti-money laundering (AML) and know-your-customer (KYC) requirements.
The need for clear and consistent regulatory frameworks is paramount. This necessitates ongoing collaboration between regulators, financial institutions, and blockchain developers. Harmonising international regulations will be particularly crucial to facilitate seamless cross-border blockchain compliance for instruments like tokenised bills of exchange. Without a predictable and supportive regulatory environment, the full potential of tokenisation cannot be realised, creating uncertainty for blockchain adoption challenges in the financial sector.
Scalability and Adoption: The Path to Widespread Implementation
Beyond regulation, the widespread enterprise blockchain future hinges on addressing several practical blockchain adoption challenges. One significant hurdle is the technological integration of new blockchain systems with existing legacy systems within financial institutions. These legacy systems are deeply entrenched and often complex, requiring careful interoperability solutions to ensure smooth data flow and operational continuity.
Furthermore, interoperability finance among different blockchain networks is crucial. A future where assets are tokenised on various chains requires mechanisms for these networks to communicate and transfer assets seamlessly. This prevents fragmentation and ensures a truly interconnected on-chain finance scalability. Fostering a common understanding and building trust across diverse stakeholders—from banks and corporations to legal and tech professionals—is also vital for successful implementation. Solana and other high-performance blockchains will continue to refine their infrastructure, focusing on developer tools, security enhancements, and enterprise-grade features to support the massive transactional demands of global finance. The global trade blockchain outlook is bright, but it requires concerted effort on technological refinement, regulatory clarity, and industry-wide collaboration to move from proof of concept to pervasive reality.
