PAX Gold (PAXG) is a gold-backed cryptocurrency designed to make ownership of physical gold as portable and programmable as an Ethereum$1,686.33 token. Issued by Paxos, PAXG aims to bridge traditional bullion markets and onchain finance by representing direct, allocated ownership of vaulted gold while preserving the transferability and composability of an ERC-20 asset. [1]
Background and issuer
PAXG was introduced by Paxos, a blockchain infrastructure company known for building regulated tokenization and settlement products. Paxos traces its roots to earlier crypto market infrastructure initiatives and later established itself as a regulated trust company in the United States, positioning PAXG as a token that prioritizes transparency and compliance alongside crypto-native usability. PAXG was launched in 2019 with the core thesis that investors should not have to choose between the financial properties of gold and the speed and accessibility of digital assets. [1] [2]
Paxos is led by co-founder and CEO Charles Cascarilla, and the firm has emphasized creating regulated rails for tokenized real-world assets. For PAXG, this translates into a model where token holders have a claim on specific physical gold held in custody, rather than synthetic exposure via derivatives. [3]
How PAXG works, minting, custody, and audits
PAXG is structured so that each token corresponds to one fine troy ounce of a London Good Delivery gold bar, with the underlying metal held in professional vault facilities. This allocated structure is intended to distinguish PAXG from products that pool metal without assigning ownership to specific bars. In practice, tokenization enables smaller, divisible units of gold ownership that are easier to transfer than physical bullion. [1]
The lifecycle of PAXG involves minting and redemption processes that connect onchain tokens to offchain bullion. When demand for PAXG increases through supported channels, Paxos mints new tokens against additional gold that is acquired and placed into custody. Conversely, eligible holders can redeem PAXG through Paxos for physical gold or its cash equivalent under the issuer’s terms, which is designed to help keep the token’s backing aligned with the circulating supply. Custody is generally described as insured and handled by established vault providers, reducing the operational burden for holders who want gold exposure without arranging storage and security themselves. [1] [4]
Transparency is reinforced through regular attestations and audit practices intended to confirm that the gold held in custody matches token liabilities. This auditing layer is central to PAXG’s credibility as “digital gold,” because it provides external verification of reserves rather than relying solely on issuer claims. [1]
Use cases and ecosystem across wallets, exchanges, and DeFi
PAXG’s primary use case is straightforward gold exposure in a crypto-compatible form. Instead of buying, shipping, and storing bullion, users can hold PAXG in standard Ethereum wallets and transfer it globally with typical onchain settlement properties. Because it is an ERC-20 token, PAXG can also be integrated into exchange infrastructure, custody solutions, and portfolio tooling that already supports Ethereum assets. [1]
A second major use case is onchain collateralization. In decentralized finance, PAXG can function as a gold-linked collateral asset in protocols that support it, enabling holders to potentially borrow, lend, or provide liquidity while maintaining a gold-backed position. This expands the utility of gold beyond passive holding by making it composable with smart contracts, although users still face the typical DeFi considerations such as protocol risk and smart contract vulnerabilities. [4]
PAXG is differentiated by its combination of allocated physical backing, insured professional custody, and a compliance-oriented issuer, all wrapped in a transferable Ethereum token. For market participants who view gold as a long-standing store of value but want the liquidity, portability, and programmability of crypto rails, PAXG represents a pragmatic bridge between bullion ownership and onchain finance.
