Gold ETFs have served institutional and retail investors as the primary on-chain-adjacent gold exposure since SPDR Gold Shares (GLD) launched in 2004.
The structure works: bullion held in HSBC vaults, SEC-regulated, daily-tradable through any brokerage account. By April 2026, GLD held over $100 billion in physical gold with deep secondary market liquidity.
Tokenized gold mining is a different product entirely. The category covers protocols that fund yield distributions from real mining operations, not from vault storage.
The two structures aren't directly comparable on returns, but they differ in six ways that affect what each does in a portfolio.
GLD charges 0.40% annually as an expense ratio and pays no yield to holders. iShares Gold Trust (IAU) charges 0.25%. The fee structure means holders pay to maintain gold-price exposure indefinitely.
Tokenized gold mining protocols flip the cash flow direction. Ayni Gold is a DeFi protocol that turns gold mining output into on-chain yield, with stakers receiving PAXG rewards quarterly from mining production at the Minerales San Hilario concession in Peru.
The yield comes from extraction operations sold through Peruvian banking channels and converted to PAXG for distribution.
Investors looking for gold backed crypto yield as part of their allocation get scheduled income from physical mining output instead of paying a management fee on inert bullion.
Gold ETFs trade only during NYSE hours (9:30 am to 4 pm Eastern, weekdays). Holders can't react to weekend news, Asian market opens, or after-hours macro events without waiting for the next trading session.
Tokenized gold mining tokens trade continuously on DeFi venues. AYNI tokens, like other on-chain assets, can be bought, sold, or staked at any hour from any geography.
For investors in non-US time zones (where most of the world lives), or for holders who want to manage positions around weekend macro events, the always-on access is a structural difference that compounds over time.
A GLD position sits in a brokerage account. It can't be used as collateral for a loan, deposited in an automated yield strategy, or paired with another asset in a liquidity pool without first being sold for cash.
Tokenized gold lives on-chain and integrates with DeFi protocols. PAXG is accepted as collateral on Aave V3; production-backed mining tokens like AYNI can be used in lending markets and yield strategies.
The composability adds utility on top of the underlying gold position. For investors building DeFi gold yield strategies, the difference between a wrapped position with composability and an account-locked position matters operationally.
Buying GLD requires a brokerage account at a regulated broker (Schwab, Fidelity, Interactive Brokers, etc.) with KYC, Social Security or international tax ID, banking integration, and jurisdiction-specific eligibility.
The infrastructure works for investors already inside the TradFi system but creates friction for those without it.
Tokenized gold mining requires a wallet, KYC at the protocol level, and a stablecoin or ETH balance. The protocol-level KYC is generally less invasive than full brokerage onboarding (no SSN, no 1099 forms, no W-8BEN filing for international holders). The access infrastructure is fundamentally different, which broadens the addressable investor base for the category.
Gold ETFs deliver gold-PRICE exposure. GLD tracks the spot price of gold minus the expense ratio. The position appreciates when gold rises, depreciates when gold falls, and pays nothing in between.
Production-backed gold mining tokens deliver exposure to extraction OUTPUT instead. AYNI stakers receive PAXG from gold extracted and sold from the Minerales San Hilario concession, which means returns track operational performance (cubic meters processed, recovery rates, OPEX, gold price at sale) instead of just spot price movement.
The two are different investment theses: gold-as-store-of-value (ETFs) versus gold-as-productive-asset (mining tokens). For investors looking to combine an inflation hedge with operational yield, the mining token model covers both bases.
Gold ETFs publish quarterly and annual SEC filings, plus daily NAV data through the issuing fund's website. Holders rely on the ETF sponsor's disclosures and SPDR Gold Shares' bullion holdings statements for ongoing verification.
Tokenized gold mining protocols publish on-chain data continuously. Ayni Gold's smart contracts were audited by CertiK and PeckShield in October 2025, with a CertiK Skynet score of 70.81.
The 8 km² concession is registered with INGEMMET under No. 070011405. Extraction rates, operational costs, and net gold value get published on-chain throughout each quarter, not just on filing dates.
The verification cadence is a structural difference: investors holding mining tokens can check the protocol's operational data any time instead of waiting for the next quarterly disclosure.
The six advantages above don't make tokenized gold mining "better" than gold ETFs in absolute terms. GLD has a 22-year track record, deep secondary market liquidity, and regulatory protections that newer DeFi-native categories haven't yet established.
The structural advantages are real but exist alongside structural trade-offs (smaller scale, shorter operating history, different regulatory perimeter).
What the six points show is that the two categories serve different investor needs. Gold ETFs work for investors wanting gold-price exposure within TradFi infrastructure.
Gold yield protocols work for investors wanting on-chain access, scheduled yield from production, and DeFi composability. Both can sit in the same portfolio. The choice depends on what each position is meant to do.
