ARC: Add PAX Gold (PAXG) Collateral & Borrow Support

Sentence Rational

For thousands of years gold has functioned as collateral and we would like to extend this capability and borrowing to the DeFi ecosystem through Aave. PAX Gold is the largest market cap tokenized gold coin - each PAXG token represents and is backed by one troy ounce of gold.

Paragraph Summary

PAX Gold was the first and is the largest digital gold token. PAXG launched in 2019 with the mission to make the ownership of physical gold safer, cheaper, and more convenient. Since then the token has grown to over $160M in market capitalization and has been listed on a variety of institutions including FTX, Binance, Kraken, BlockFi, itBit, and Celsius.

We have seen an enthusiastic customer base in particular for being able to use digital gold as collateral and earn yield on CeFi platforms like BlockFi and Celsius. Some users however cannot, or choose not to, use CeFi institutions and we would like to ensure DeFi users can experience the same benefits of using gold as collateral and/or to generate yield.

Listing PAX Gold will provide a new trustworthy, secure, deflationary method for users to store value in the crypto ecosystem and help DeFi users build a diversified digital portfolio.

1. What is the link between the author of the AIP and the Asset?
The AIP submitter, Paxos Trust Company, is the sole issuer of the PAX Gold token. Paxos Trust Company is a regulated financial institution and qualified custodian.

2. Provide a brief high-level overview of the project and the token
PAX Gold was launched to provide a safe, affordable, and convenient way to own investment-grade gold. Each token is fully backed by one troy ounce of London-good delivery gold bars held in Brinks vaults in London. Users can redeem gold bars directly or in smaller quantities through our partner Alpha Bullion.

3. Explain positioning of token in the AAVE ecosystem. Why would it be a good borrow or collateral asset?
Gold is an ideal and proven asset for collateral because it has relatively low volatility and is deflationary by nature. From what we understand, most gold borrowers are institutions borrowing to create liquidity or maintain PAXG markets through healthy arbitrage.

4. Provide a brief history of the project and the different components: DAO, products; and how it overcame stressed conditions
PAXG is available for trading on Uniswap and many centralized exchanges

5. How is the asset currently used?
Primary use cases are buy/sell, trade, hold, send/receive, use as collateral, and borrow.

6. Emission schedule
PAXG tokens are minted/burned based on client demand. The process for minting and burning has been approved by the NYDFS and is regularly audited by a third party. Full monthly attestations available on the paxos website. Market cap fluctuates as users purchase and redeem PAXG.

7. Token permissions and upgradability

  1. Note that all of the following roles are held by multi-sig addresses.

  2. Controlling the token supply - The supplyController address can mint and burn the token based on the actual movement of gold in and out of the reserve based on requests for the purchase, conversion and redemption of PAXG.

  3. Contract Owner - Can pause/unpause the contract and propose a new owner.

  4. Asset Protection Role - As required by our regulators, we have introduced a role for asset protection to freeze or seize the assets of a criminal party when required to do so by law, including by court order or other legal process.

  5. Upgradeability Proxy - To facilitate upgradeability on the immutable blockchain we follow a standard two-contract delegation pattern: a proxy contract represents the token, while all calls not involving upgrading the contract are delegated to an implementation contract. The proxy used here is AdminUpgradeabilityProxy from ZeppelinOS.

8. Market data (Market Cap, 24h Volume, Volatility, Exchanges, Maturity)

  1. Market Cap = ~$168M
  2. 24hr trading volume: $10M - $30M
  3. Exchanges: Uniswap, Binance, Kraken, FTX, itBit, Gemini

Here’s a post by Coindesk on the growth of gold-backed assets and how - let’s get gold, which is one of the most widely accepted forms of collateral, on Aave.

Why is the market cap only $160m? PAXG is widely distributed and highly regulated and inflation is accelerating. The market cap seems really low relative to PAXG’s position in the market. Why haven’t more people bought it? It seems like the ideal way to own gold. I own some PAXG and plan to own it for a long time. I think it would be a great collateral asset on Aave.

Thank you for your support - we are glad you own $PAXG, and we agree it’s the most affordable and convenient way to own institutional grade gold!

Market cap is closer to $275M; we don’t know why CoinMarketCap has incorrect data but Etherscan and CoinGecko has it correct.

Any update on this? I strongly support PAXG as a collateral.

PAXG has a small, 2bps ‘fee on transfer’ mechanism to help cover storage of the gold in Loco London vaults. We spoke with Aave core team and it looks like Aave is not compatible with a ‘fee on transfer’ model. We are evaluating options with the team and are excited to eventually bring tokenized gold to Aave.

any news on this topic now that v3 is out? @Paxos_Global

yea, is there any update on this from the paxos team?

Any news ?


I also think that adding PAX Gold to the platform in the future would be relevant. It is the most widely used precious metal based asset in the market and has good liquidity. In times of economic uncertainty, this provides diversification. I think a lot of holders would be interested in using theirs as collateral.
