I. Introduction: The Return of Safe-Haven Demand in the New Cycle

Since the beginning of 2025, frequent geopolitical conflicts, persistent inflationary pressures, and sluggish growth in major economies have led to a renewed demand for safe-haven assets. Gold, as a traditional "safe asset," has once again become the focus, with gold prices reaching new highs, surpassing the $3,000 per ounce mark, becoming a haven for global capital. Meanwhile, with the accelerated integration of blockchain technology and traditional assets, "Tokenized Gold" has emerged as a new trend in financial innovation. It not only retains the value-preserving properties of gold but also possesses the liquidity, composability, and smart contract interaction capabilities of on-chain assets. An increasing number of investors, institutions, and even sovereign funds are beginning to incorporate tokenized gold into their investment strategies.

II. Gold: The Irreplaceable "Hard Currency" in the Digital Age

Despite the fact that humanity has entered a highly digitalized financial era, with various financial assets continuously emerging—from fiat currencies, government bonds, and stocks to the rise of digital currencies in recent years—gold has maintained its status as the "ultimate store of value" due to its unique historical depth, value stability, and cross-sovereign currency attributes. Gold is referred to as "hard currency" not only because of its natural scarcity and physical non-falsifiability but also because it embodies a long-standing consensus of human society over thousands of years, rather than being backed by the credit of a specific country or organization. In any macroeconomic cycle where sovereign currencies may depreciate, fiat currency systems may collapse, and global credit risks accumulate, gold has always been viewed as the last line of defense and the ultimate means of payment under systemic risk.

In the past few decades, especially after the collapse of the Bretton Woods system, gold was once marginalized, with its role as a direct settlement tool replaced by the US dollar and other sovereign currencies. However, it has been proven that credit currencies cannot completely escape the fate of cyclical crises; gold's status has not been erased but rather has been redefined as a value anchor in each round of monetary crises. The 2008 global financial crisis, the wave of global monetary easing following the pandemic in 2020, and the high inflation and interest rate shocks since 2022 have all led to a significant rise in gold prices. Especially after 2023, multiple factors such as geopolitical friction, risks of US debt default, and persistent global inflation have pushed gold back to the important threshold of $3,000 per ounce, triggering a new shift in global asset allocation logic.

The actions of central banks are the most direct reflection of this trend. According to data from the World Gold Council, global central banks have continuously increased their gold holdings over the past five years, particularly with "non-Western countries" like China, Russia, India, and Turkey showing particularly active engagement. In 2023, the global net purchase of gold by central banks exceeded 1,100 tons, setting a historical record. This round of gold repatriation is essentially not a short-term tactical operation but rather a deep consideration for strategic asset security, the multipolarization of sovereign currencies, and the increasingly declining stability of the dollar system. In the context of ongoing restructuring of global trade patterns and geopolitical landscapes, gold is once again viewed as the most trusted reserve asset. From the perspective of monetary sovereignty, gold is replacing US Treasury bonds as an important anchor for many central banks adjusting their foreign exchange reserve structures.

More structurally significant is the fact that gold's safe-haven value is being recognized again by global capital markets. Compared to credit assets like US Treasury bonds, gold does not rely on the issuer's repayment ability and does not carry default or restructuring risks. Therefore, in the context of high global debt and continuously expanding fiscal deficits, gold's "no counterparty risk" attribute is particularly prominent. Currently, the debt-to-GDP ratio of major global economies generally exceeds 100%, with the US exceeding 120%. Increasing doubts about fiscal sustainability make gold irreplaceably attractive in an era of weakened sovereign credit. In practice, large institutions such as sovereign wealth funds, pension funds, and commercial banks are raising their allocation to gold to hedge against systemic risks in the global economy. This behavior is changing gold's traditional "counter-cyclical + defensive" role, positioning it more as a "structurally neutral asset" in the long term.

Of course, gold is not a perfect financial asset; its trading efficiency is relatively low, physical transfer is difficult, and it is challenging to program. These inherent flaws make it seem somewhat "heavy" in the digital age. However, this does not mean it will be eliminated; rather, it prompts gold to undergo a new round of digital upgrades. We observe that the evolution of gold in the digital world is not a static preservation of value but an active integration of financial technology logic towards "tokenized gold." This shift is no longer a competition between gold and digital currencies but a combination of "value-anchoring assets and programmable financial protocols." The on-chain nature of gold injects liquidity, composability, and cross-border transfer capabilities, allowing gold to serve not only as a wealth carrier in the physical world but also to become an anchor for stable assets in the digital financial system.

It is particularly noteworthy that gold, as a store of value, has a complementary rather than absolute replacement relationship with Bitcoin, the "digital gold." Bitcoin's volatility is far greater than that of gold, lacking sufficient short-term price stability, and in an environment of high macro policy uncertainty, it is more likely to be viewed as a risk asset rather than a safe-haven asset. In contrast, gold maintains its threefold advantages of anti-cyclicality, low volatility, and high recognition due to its large spot market, mature financial derivatives system, and widespread acceptance at the central bank level. From the perspective of asset allocation, gold remains one of the most important risk-hedging factors in building a global investment portfolio, holding an irreplaceable underlying "financial neutrality" position.

Overall, whether from the perspective of macro financial security, the restructuring of the monetary system, or the reconstruction of global capital allocation, gold's status as hard currency has not weakened with the rise of digital assets; rather, it has been further enhanced by global trends such as "de-dollarization," geopolitical fragmentation, and sovereign credit crises. In the digital age, gold is both a stabilizing force in the traditional financial world and a potential value anchor for future on-chain financial infrastructure. The future of gold is not to be replaced but to continue its historical mission as the "ultimate credit asset" through tokenization and programmability, bridging the old and new financial systems.

III. Tokenized Gold: The Golden Expression of On-Chain Assets

Tokenized Gold is essentially a technology and financial practice that maps gold assets onto blockchain networks in the form of encrypted assets. It represents the ownership or value of physical gold through smart contracts, allowing gold to no longer be limited to static records in vaults, storage receipts, and banking systems, but to circulate and combine freely on-chain in a standardized and programmable form. Tokenized Gold is not a creation of a new type of financial asset but a reconstruction method that injects traditional commodities into the new financial system in digital form. It embeds gold, a hard currency across historical cycles, into the "decentralized financial operating system" represented by blockchain, giving rise to a new value-carrying structure.

This innovation can be understood as an important part of the global wave of asset digitization. The widespread adoption of smart contract platforms like Ethereum provides the underlying programmable foundation for gold's on-chain expression; meanwhile, the development of stablecoins in recent years has validated the market demand and technical feasibility for "on-chain value-anchoring assets." In a sense, Tokenized Gold is an extension and elevation of the stablecoin concept, pursuing not only price anchoring but also having real, no credit default risk hard asset support behind it. Unlike fiat-backed stablecoins, gold-backed tokens naturally escape the volatility and regulatory risks of a single sovereign currency, possessing cross-border neutrality and long-term anti-inflation capabilities. This is particularly important in the current context where the dollar-dominated stablecoin landscape increasingly raises regulatory and geopolitical sensitivities.

From a micro-mechanism perspective, the generation of Tokenized Gold typically relies on two paths: one is a "100% physical collateral + on-chain issuance" custody model, and the other is a "programmatic mapping + verifiable asset certificates" protocol model. The former, such as Tether Gold (XAUT) and PAX Gold (PAXG), has physical gold custodians behind it, ensuring that each token corresponds to a specific amount of physical gold and is regularly audited and reported off-chain. The latter, such as Cache Gold and Digital Gold Token, attempts to enhance the token's verifiability and liquidity by binding programmable asset certificates to gold batch numbers. Regardless of the path taken, the core goal is to construct a mechanism for the credible representation, liquidity, and settlement of gold on-chain, thereby achieving real-time transferability, divisibility, and combinability of gold assets, breaking the traditional gold market's issues of fragmentation, high barriers to entry, and low liquidity.

The greatest value of Tokenized Gold lies not only in the technological expression but also in its fundamental transformation of the functionality of the gold market. In the traditional gold market, trading physical gold typically incurs high transportation, insurance, and storage costs, while paper gold and ETFs lack true ownership and on-chain combinability. Tokenized Gold seeks to provide a new form of gold that is splittable, can be settled in real-time, and is capable of cross-border flow through its on-chain native asset form, transforming gold from a "static asset" into a dynamic financial tool with "high liquidity + high transparency." This characteristic greatly expands the available scenarios for gold in DeFi and global financial markets, allowing it to serve not only as a store of value but also to participate in collateralized lending, leveraged trading, yield farming, and even cross-border clearing and settlement.

Furthermore, Tokenized Gold is driving the gold market's transition from centralized infrastructure to decentralized infrastructure. In the past, the flow of gold's value heavily relied on traditional centralized nodes such as the London Bullion Market Association (LBMA), clearing banks, and vault custodians, leading to issues such as information asymmetry, cross-border delays, and high costs. Tokenized Gold, utilizing on-chain smart contracts, constructs a system for the issuance and circulation of gold assets that does not require permission or trust in intermediaries, making the processes of title confirmation, settlement, and custody of traditional gold transparent and efficient, significantly lowering market entry barriers, allowing retail users and developers to equally access the global gold liquidity network.

Overall, Tokenized Gold represents a profound value reconstruction and system integration of traditional physical assets in the blockchain world. It not only inherits the safe-haven attributes and store of value functions of gold but also expands the functional boundaries of gold as a digital asset in the new financial system. In the context of the global financial digitization and the multipolarization of the monetary system, the on-chain reconstruction of gold is destined to be not a temporary attempt but a long-term process accompanying the evolution of financial sovereignty and technological paradigms. Those who can establish a tokenized gold standard that combines compliance, liquidity, composability, and cross-border capabilities in this process may gain the discourse power of the future "on-chain hard currency."

IV. Analysis and Comparison of Mainstream Tokenized Gold Projects

In the current crypto-financial ecosystem, Tokenized Gold has emerged as a bridge connecting the traditional precious metals market with the new on-chain asset system, giving rise to a number of representative projects. These projects explore various dimensions such as technical architecture, custody mechanisms, compliance paths, and user experience, gradually constructing a prototype market for "on-chain gold." Although they all adhere to the basic principle of "physical gold collateral + on-chain mapping," the specific implementation paths and focuses differ, reflecting that the tokenized gold sector is still in a stage of competition and undefined standards.

Currently, the most representative tokenized gold projects include: Tether Gold (XAUT), PAX Gold (PAXG), Cache Gold (CGT), Perth Mint Gold Token (PMGT), and Aurus Gold (AWG). Among them, Tether Gold and PAX Gold can be seen as the current industry leaders, not only leading in market capitalization and liquidity but also gaining an advantage in user trust and exchange support due to their mature custody systems and high transparency.

Tether Gold (XAUT) is launched by the stablecoin leader Tether, characterized by its one-to-one anchoring with standard gold bars in the London gold market, with each XAUT corresponding to one ounce of physical gold held in Switzerland. This project leverages the Bitfinex ecosystem behind Tether, possessing first-mover advantages in liquidity, trading channels, and stability. However, Tether Gold is relatively conservative in disclosure and transparency, as users cannot directly view the binding information of each token to specific gold bar numbers on-chain. This black-box asset custody method has raised controversy in the highly decentralized crypto community. Additionally, XAUT's compliance layout primarily targets international offshore users, making the entry barriers still high for investors looking to invest in tokenized gold through formal financial channels.

In contrast, PAX Gold (PAXG), launched by the US-licensed fintech company Paxos, has gone further in compliance and asset transparency. Each PAXG also represents one ounce of London standard gold and provides users with on-chain queryable asset correspondence information through verifiable gold bar serial numbers and custody data. More importantly, Paxos, as a trust company regulated by the New York State Department of Financial Services (NYDFS), has its gold asset custody and issuance mechanisms subject to regulatory scrutiny, which enhances PAXG's compliance endorsement to some extent. The project is also actively expanding DeFi compatibility, having integrated with multiple DeFi protocols such as Aave and Uniswap, allowing PAXG to serve as collateral for lending and liquidity mining, thereby unlocking the composite value of gold assets on-chain.

Cache Gold (CGT) represents another attempt at tokenized gold that leans towards decentralization and verifiable asset certificates. This project employs a "Token Wrapper + gold bar number registration" system, with each CGT representing one gram of physical gold, bound to the batch number of gold held in an independent custody warehouse. Its main feature is the strong binding mechanism between on-chain and off-chain, requiring each gold collateral to generate a corresponding Proof of Reserve, with batch information and liquidity status recorded on the blockchain. This mechanism allows users to transparently track the physical assets behind the tokens, but it also poses challenges in terms of custody efficiency and liquidity organization, and has not yet been widely adopted in mainstream DeFi scenarios.

Perth Mint Gold Token (PMGT) is the official tokenized gold product launched by the Australian government-owned Perth Mint. The gold assets behind this project are guaranteed by the Australian government and held in a national-level vault, theoretically making it one of the projects with the strongest credit in tokenized gold. However, due to its low participation in the cryptocurrency market, scarcity of trading pairs, and lack of DeFi compatibility, this project, while possessing high security and official endorsement, lags far behind Tether Gold and PAX Gold in market liquidity and user adoption.

There are also innovative projects like Aurus Gold (AWG) and Meld Gold, which attempt to build new paradigms of tokenized gold through diversified custodians, NFT packaging, and cross-chain issuance. For example, Aurus Gold adopts a model of joint issuance by multiple mints and integration with various exchanges and wallets to enhance the anti-centralization dependency of gold tokens, introducing NFTs as wrapping certificates for gold to provide flexibility in asset management. These projects are more aligned with the Web3 native asset system concept but are still in the early stages and have not yet established widespread market consensus.

Overall, the current tokenized gold market presents a polarized pattern: on one hand, there are "centralized + high-trust" projects represented by Tether Gold and PAX Gold, which quickly occupy mainstream market share due to backing by large institutions, mature custody structures, and exchange access advantages; on the other hand, there are "decentralized + verifiable" projects represented by Cache Gold and Aurus Gold, emphasizing asset transparency and on-chain autonomy, but still limited by market acceptance, custody coordination efficiency, and DeFi integration levels. The competition between the two reflects the ongoing struggle in the entire crypto-financial ecosystem between "trust thresholds" and "technological ideals."

From the perspective of industry evolution trends, the future standards for tokenized gold are likely to evolve towards four directions: "compliance, verifiability, composability, and cross-chain capabilities." On one hand, only by establishing transparent custody systems in a strong regulatory environment and verifying assets through audits and on-chain validation can long-term trust from mainstream institutions and users be obtained; on the other hand, projects must truly integrate into DeFi and Web3 infrastructures to realize the "asset primitivization" of gold tokens; otherwise, they will merely be "gold certificates under financial packaging," failing to release sufficient utility value and network effects.

V. Investor Perspective on Tokenized Gold: Value, Opportunities, and Risks

As an emerging financial tool that combines traditional value anchoring with on-chain asset characteristics, Tokenized Gold is gradually becoming an alternative asset option in investors' portfolios. Unlike traditional gold ETFs or physical gold bars, its core value lies not only in the safe-haven properties represented by gold itself but also in the enhanced liquidity, improved trading convenience, and expanded composability gained through blockchain infrastructure. From the investor's perspective, the appeal of tokenized gold lies in its ability to find a relatively balanced entry point between "financial stability anchor" and "technological innovation dividend," making it a practical path for allocating "on-chain hard currency" against the backdrop of high volatility in the crypto market.

First, tokenized gold naturally inherits the basic investment logic of gold as a global safe-haven asset. Historical experience shows that during periods of increased macroeconomic uncertainty, heightened inflationary pressures, or rising geopolitical risks, gold typically garners risk premiums in capital markets, becoming the preferred target for institutions and individual investors to hedge against the decline in fiat purchasing power and severe market fluctuations. Tokenized gold continues this attribute, especially during periods of severe volatility in the crypto market, providing investors with low correlation or even negative correlation asset allocation opportunities. In the downturns of the crypto market in 2022 and 2023, the price fluctuations of tokens like PAXG and XAUT were significantly lower than those of mainstream crypto assets, even becoming a "on-chain safe haven" for short-term capital.

Secondly, tokenized gold endows gold assets with unprecedented liquidity and accessibility. Traditional gold investments face multiple pain points, including high trading thresholds, limited trading hours, inconvenient access, and strong regional restrictions. Tokenized gold, as an ERC-20 or cross-chain asset, can be transferred instantly in any wallet supporting public chains globally, and can also facilitate high-frequency trading, DeFi staking, cross-border settlements, and various advanced financial operations. This leap in liquidity greatly enhances the operational space of gold assets, transforming them from merely "asset storage" functions into dynamically manageable "on-chain cash flow foundational assets."

More importantly, as DeFi and Web3 infrastructures gradually mature, tokenized gold is gaining composable financial attributes, making it not just "digital forms of gold" but gradually becoming a component module of on-chain native assets. Investors can obtain stablecoins by collateralizing PAXG, thereby releasing liquidity to participate in other investment opportunities; they can also add gold assets to liquidity pools to earn returns; or even transfer tokenized gold across chains in multi-chain interoperability protocols to meet global payment and settlement needs. This "asset as protocol" concept is an innovative path that cannot be realized in traditional gold financial systems.

However, despite the many advantages of tokenized gold, it still carries certain structural risks and development bottlenecks that investors need to weigh carefully when participating. First is the custody and redemption risk; the vast majority of tokenized gold projects still rely on centralized physical custody systems, requiring investors to trust that the issuers can properly safeguard the gold long-term and provide physical redemption when necessary. Currently, most projects have cumbersome redemption processes, high thresholds, and regional limitations, especially in extreme market conditions, whether users can smoothly complete the conversion from on-chain assets to physical gold remains uncertain legally and operationally. Additionally, some projects lack sufficient transparency in custody audits and asset proofs, which can undermine user confidence and hinder their long-term function as "on-chain safe-haven anchors."

Secondly, there are external risks related to compliance and regulation. Since gold itself is a high-value sensitive asset, its tokenization process involves multiple regulatory requirements from the precious metals market, securities laws, KYC/AML, etc. The legality and regulatory paths of tokenized gold vary across different jurisdictions, meaning that the legal risks faced by projects have a high degree of uncertainty. This is particularly crucial for institutional users looking to use such assets for cross-border settlements or large transactions, as how to operate robustly within a compliance framework is a key factor determining their acceptance.

Finally, from the perspective of market dynamics, tokenized gold's position in actual investment portfolios remains "auxiliary allocation," making it difficult to become a dominant asset. Although its safe-haven and stability characteristics hold significant value during downturns, in bullish environments, its performance often lags behind risk-oriented crypto assets like Bitcoin and Ethereum. This "value stability but limited growth" characteristic makes tokenized gold more suitable as a tool for hedging volatility and stabilizing portfolio returns rather than a core investment target pursuing high growth.

In summary, tokenized gold represents both a "value storage tool" for a new type of asset and a "safety-first" allocation option in the digital economy world for investors. Its intrinsic logic is built on the stable value of gold over millennia, reshaping its trading, custody, and composability capabilities through blockchain technology. With the further development of the DeFi ecosystem, the improvement of cross-chain infrastructure, and the gradual clarification of compliance paths, tokenized gold may play a more significant role in the "full lifecycle management of digital assets." For individual users, it offers a practical path to enhance asset risk resistance and make counter-cyclical allocations; for institutions, it may become the "core asset" in building on-chain portfolios, thus ushering in a true new era of "on-chain asset management."

VI. Conclusion: The On-Chain Upgrade of Gold is Not Replacement but Continuation

In an era of unstable credit, increased dollar volatility, and the restructuring of the global monetary landscape, gold is undergoing a process of "digital rediscovery." It is not being replaced by digital assets like Bitcoin but is being tokenized, programmed, and smart-contract-enabled, thus participating in the construction of the new financial system in a more flexible form. For users, this evolving gold remains "hard currency," just in a different on-chain form. It continues to provide security, value retention, and risk resistance, becoming a true "stability anchor" in the digital world.
