Gold Tokenization Development Services for Platforms Built on Real Custody Infrastructure
SpaceDev designs and builds gold tokenization platforms for bullion companies, commodity funds, fintech firms, and digital asset issuers that need a production-grade system, not a white-label template with your logo on it. We cover the full stack: token issuance contracts, vault custody integration, Proof of Reserves verification, KYC/AML onboarding, investor portals, and DeFi composability.

How Gold Tokenization Works at the Infrastructure Level
Most descriptions of gold tokenization stop at "physical gold in a vault equals a token on the blockchain." The operational reality is more complex, and the gaps between those two things are where most platform failures originate.
Vault Integration and Custody Verification
The platform must maintain a live, verified connection between physical gold holdings and minted token supply. This requires API integration with your vault provider, automated data feeds that trigger minting and burning events, and a reconciliation layer that catches discrepancies before they hit the on-chain state. Reputable vault providers include Brinks, Malca-Amit, Loomis International, and specialist custodians in Switzerland, Singapore, and London.
Proof of Reserves: On-Chain Verification That Investors Can Check
A periodic audit report in PDF format is not enough for platforms competing with PAXG or XAUt. Chainlink Proof of Reserves provides cryptographically verifiable, on-chain confirmation that the token supply is backed by gold held in custody. We implement the Chainlink PoR adapter, the vault-side data feed, and the smart contract logic that pauses minting if reserves fall below the token supply threshold.
Token Minting and Burning Tied to Physical Settlement
Every minting event must be triggered by a confirmed gold deposit, and every redemption must trigger a vault release. We build the workflow automation layer that connects these events, including pending state management, partial redemption logic, and exception handling for vault processing delays.
DeFi Composability Without Compromising Compliance
Platforms like Ondo Finance and the xStocks model (Backed Finance) have demonstrated that compliant tokenized commodities can be DeFi-composable without removing transfer restrictions entirely. We design the compliance layer to allow DeFi interactions while maintaining KYC/AML controls on the primary issuance and redemption layer, an architecture decision made at the start, not retrofitted after launch.
Gold Token Models: Choosing the Right Structure for Your Platform
Not all tokenized gold platforms are built the same way. The model you choose determines your custody requirements, regulatory exposure, and DeFi integration potential.
| Gram-Denominated | Troy Ounce-Denominated | Fractional Gold Tokens | |
|---|---|---|---|
| Unit of backing | 1 token = 1 gram of gold | 1 token = 1 troy ounce of gold | 1 token = fraction of 1 gram |
| Target audience | Retail and institutional | Institutional, high-net-worth | Micro-investors, emerging markets |
| Redemption complexity | Moderate | Higher (physical bar minimums) | High (aggregation required before redemption) |
| DeFi usability | Good | Good | Limited without aggregation layer |
| Examples | CACHE Gold (CGT) | PAX Gold (PAXG), Tether Gold (XAUt) | Custom platforms for retail access |
Unit of backing
Gram: 1 token = 1 gram of gold
Troy ounce: 1 token = 1 troy ounce of gold
Fractional: 1 token = fraction of 1 gram
Target audience
Gram: Retail and institutional
Troy ounce: Institutional, high-net-worth
Fractional: Micro-investors, emerging markets
Redemption complexity
Gram: Moderate
Troy ounce: Higher (physical bar minimums)
Fractional: High (aggregation required before redemption)
DeFi usability
Gram: Good
Troy ounce: Good
Fractional: Limited without aggregation layer
Examples
Gram: CACHE Gold (CGT)
Troy ounce: PAX Gold (PAXG), Tether Gold (XAUt)
Fractional: Custom platforms for retail access
The right denomination depends on your target user base, your vault provider's minimum lot sizes, and whether you intend to support physical redemption or cash-equivalent settlement. Our Product Discovery process maps these decisions before any development begins.

How We Build Gold Tokenization Platforms
-
Token Model and Custody Scoping
We define the denomination structure, custody model, vault integration requirements, redemption mechanics, and regulatory framework before any architecture decisions are made, coordinating your legal advisors, vault provider, and compliance team.
-
Smart Contract Development
We build the token contract with minting and burning logic tied to custody events, transfer controls appropriate to your compliance requirements, and circuit breaker mechanisms that pause issuance if reserve verification fails.
-
Proof of Reserves and Vault Integration
We implement the Chainlink PoR adapter or custom reserve verification layer connected to your vault provider's API, covering real-time holding data, minting authorization logic, and public-facing reserve dashboards.
-
KYC/AML Onboarding and Compliance Controls
We build the investor onboarding flow with identity verification, wallet screening, and jurisdictional access controls, handling different accreditation requirements across markets from day one.
-
Investor Portal, Issuer Console, and DeFi Integrations
We build the product layer: investor dashboards with real-time gold price tracking, issuer consoles for minting authorization and redemption management, and the DeFi integrations required for your token to be usable beyond the primary platform.
-
Security Review and Audit
Gold tokenization platforms are high-value targets. Every contract and integration goes through structured security review before launch, with BlockAudit available for independent validation focused on minting authorization bypasses and oracle manipulation attacks.
