How Gold Tokenization Works: An End-to-End RWA Use Case

In our previous article, we introduced the end-to-end RWA tokenization lifecycle – from defining the product and establishing its legal structure to issuing tokens, managing the underlying asset and enabling redemption. This article applies that framework to a specific use case: tokenized gold.

Gold is a familiar physical asset, yet tokenizing it requires much more than simply creating a digital token. The goal is to make gold easier to access, divide, transfer and integrate with digital financial applications – while supporting more efficient settlement and programmable lifecycle operations and preserving a verifiable link to the underlying physical gold.

This article follows a hypothetical gold-backed product – from its initial design by a financial institution to token issuance, onchain use and eventual redemption – to illustrate the full RWA tokenization lifecycle.

High-Level Overview of Tokenizing Gold

Consider a bank that decides to offer XYZ Gold (XYZG), a tokenized gold product for its KYC-verified customers.

Step 1: Structure and Back the Product

The bank defines XYZ Gold, procures the gold and establishes its terms.

Step 2: Deploy and Mint the Tokens

The bank deploys XYZG on a blockchain and mints tokens against allocated gold.

Step 3: Distribute Tokens and Settle Purchases

Eligible customers purchase XYZG and receive the tokens in approved wallets or bank-managed accounts.

Step 4: Hold, Transfer or Trade

Customers use approved wallets and marketplaces.

Step 5: Reconcile and Verify the Backing

The issuer reconciles circulating XYZG against custodian records, supported by periodic independent reserve verification.

Step 6: Redeem and Burn

Customers redeem XYZG, and the corresponding tokens are removed from circulation.

Tokenizing Gold: An End-to-End Process Explained

Step 1: Structure and Back the Product

The bank would typically define the following:

• Product name: XYZ Gold (XYZG)
• Eligible customers: KYC-verified customers in approved markets
• Backing model: The circulating XYZG supply is fully backed by eligible physical gold allocated to the product
• Token denomination: For example, 1 XYZG corresponds to 1 gram of fine gold
• Customer rights: The legal or contractual rights attached to each token
• Trading and transfer options: Where and how customers can transact
• Redemption options: Physical gold, fiat, stablecoins or a combination
• Pricing and fees: Purchase, custody, trading and redemption charges
• Other terms and regulatory requirements

To establish the backing, the bank would work with approved bullion dealers, assayers, custodians and vault operators to:

• procure investment-grade gold meeting the product’s defined quality standards;
• verify its weight, purity and authenticity;
• allocate the eligible gold to the XYZ Gold product;
• hold it through a secure and appropriately insured custody arrangement; and
• establish ongoing reconciliation and independent reserve-assurance processes.

Step 2: Deploy and Mint the Tokens

The bank selects a blockchain network and deploys audited smart contracts for XYZG on the network.

Once the custodian confirms that eligible gold has been received and allocated, the bank authorizes an equivalent quantity of XYZG to be minted on the blockchain network.

                ↓

The blockchain enables:

A. Token creation and destruction

• Mint XYZG when additional eligible gold is allocated
• Burn XYZG when the underlying gold is redeemed
• Make total token supply and minting and burning events verifiable onchain
• Restrict minting and burning to authorized parties

B. Digital ownership records:

• Record how many XYZG tokens each wallet controls
• Record all token transfers
• Maintain an auditable history of minting and burning
• Allow customers and auditors to verify onchain activity

Private keys authorize transactions from self-custodied wallets. The bank may also offer custodial wallets in which it securely manages access on behalf of customers.

The blockchain records token balances and transfers. The product terms establish the holder’s legal rights over the corresponding gold.

C. Programmable product rules via smart contracts can:

• permit transfers only between KYC-approved wallets;
• prevent transfers involving addresses identified as restricted under the product’s compliance rules;
• enforce customer holding or transaction limits;
• prevent unauthorized token creation;
• calculate transaction and redemption fees;
• lock tokens when a redemption request begins;
• burn tokens after redemption is completed;
• require multiple approvals for sensitive actions;
• separate minting, compliance and emergency permissions;
• pause minting or transfers during an incident; and
• support atomic delivery-versus-payment when XYZG and the payment asset can both settle through compatible onchain infrastructure.

These controls depend on identity, sanctions and eligibility systems supplying accurate and current information to the onchain contracts.

D. Transparent transaction history

A blockchain explorer or bank dashboard can display:

• total XYZG supply and, where defined, circulating supply;
• minting and burning events;
• transfers between wallets;
• transaction status and timestamps; and
• relevant smart-contract activity.

Customer names, KYC documents and other sensitive personal information should generally remain offchain, while the blockchain records only the eligibility status, attestations or references required to enforce the product’s rules.

E. Fast, low-Cost settlement

XYZG transfers can achieve fast onchain finality with low network fees. When integrated with custody, banking and payment infrastructure, the broader settlement process can also become significantly more efficient, while maintaining compatibility with existing financial systems.

F. Application integrations

XYZG can potentially integrate with approved:

• wallets and custody platforms;
• centralized exchanges and brokers;
• decentralized exchanges;
• lending and collateral applications;
• managed investment vaults;
• portfolio-management platforms; and
• fiat and stablecoin on- and off-ramps.

These integrations can extend XYZG beyond holding and trading. Subject to the product’s legal terms, eligible holders could use XYZG in approved lending, collateral or professionally managed onchain strategies. Such activities would be optional and would introduce additional utility and risks beyond those associated with holding the standard gold-backed token.

Step 3: Distribute Tokens and Settle Purchases

The bank offers XYZG through its banking application, investment platform or approved distribution partners.

Customer journey

1. The customer completes KYC and eligibility checks.
2. The customer reviews the product terms and risks.
3. The customer chooses an investment amount.
4. The bank displays the current price and applicable fees.
5. The customer pays using a supported payment method.
6. Depending on the issuance model, the corresponding XYZG is either newly minted or transferred from the issuer’s existing token inventory to the customer’s wallet or bank-managed account.
7. The XYZG transfer is recorded onchain. Any fiat payment remains within the relevant banking or payment system unless that payment leg also settles onchain.

                 ↓
5 XYZG transferred to the customer
                 ↓
Customer balance: 5 XYZG

Step 4: Hold, Transfer or Trade

Depending on the product’s permitted features, customers may:

• hold XYZG as digital gold;
• transfer it to another eligible customer;
• sell it back to the bank;
• trade it through an approved exchange or broker;
• exchange it for a supported stablecoin;
• use it for settlement where accepted; or
• redeem it for physical gold, cash or a supported stablecoin.

The blockchain records the XYZG transfer and any payment leg that also settles onchain.

If payment occurs through fiat or another offchain system, the payment and token-transfer legs must be coordinated and reconciled across the relevant systems. Also note, depending on market liquidity, demand, spreads, fees and redemption conditions, XYZG may trade above or below the reference value of its underlying gold.

Step 5: Reserves Are Reconciled and Independently Verified

Ongoing reserve assurance typically involves several participants:

• Custodian or vault operator: Maintains the bar-level inventory and confirms the eligible gold held for the product.
• Bank or issuer: Reconciles custodian records against minted, burned and circulating XYZG.
• Independent assurance provider: Periodically examines or attests to the reported reserve coverage.
• Reserve-data or oracle provider: May publish validated reserve information onchain for applications and token holders.

The blockchain shows token supply and minting and burning activity, while the custodian, issuer and independent assurance provider establish whether the reported offchain gold reserves correspond to the circulating token supply.

Core rule: Eligible fine gold held for the product ≥ Fine gold represented by circulating XYZG

Step 6: Redeem and Burn

Customers can redeem XYZG according to the product’s terms.

Cash or stablecoin redemption

1. Customer submits a redemption request.
2. The corresponding XYZG is locked.
3. The bank or its appointed redemption agent pays the customer.
4. The redeemed XYZG is burned.
5. Circulating supply decreases accordingly.

Physical-gold redemption

1. Customer requests delivery or collection.
2. The bank confirms the minimum quantity and applicable fees.
3. The corresponding XYZG is locked.
4. The bank coordinates physical-gold delivery or collection with the custodian and appointed logistics providers.
5. The redeemed XYZG is burned.
6. Gold reserves and circulating token supply are updated.

5 XYZG redeemed and burned
            ↓
Customer receives 5 grams of gold or its permitted cash equivalent
            ↓
Circulating XYZG supply decreases by 5

Conclusion

On EVM-compatible networks such as Shardeum, issuers can use ERC-20 as the base interface for a fungible token and combine it with additional components for metadata, identity, compliance, transfer controls, pricing, reserve data and application integrations. Together with smart contracts, familiar EVM tooling and established developer workflows, this provides a flexible foundation for building tokenized asset products.

While this article focused on gold, the same principles apply across a wide range of real-world assets – including government securities, private credit, commodities, real estate, investment funds and intellectual property. As tokenization continues to mature, standardized infrastructure and programmable asset lifecycles are likely to play an increasingly important role in modern financial markets.
