PAXG is Paxos's tokenized-gold offering and the most accessible of its kind for US buyers. Each token is one fine troy ounce of London Good Delivery gold held in Brink's vaults in London. The issuer is a New York State limited-purpose trust company regulated by NYDFS, which is why Coinbase, Kraken, Gemini, and Crypto.com have been willing to list it where they have not listed XAUt.
PAXG is ERC-20 only. There is no Tron deployment, no Solana deployment, no BNB Chain deployment. Every real PAXG balance is an entry in the Paxos contract on Ethereum. Wrapped or bridged representations on other chains exist but are not issuer-backed; they are DeFi IOUs from specific bridges, and they do not carry the redemption right. If you see PAXG on a non-Ethereum DEX, verify what you are actually buying.
The genuinely useful feature is redemption, which Paxos does offer to retail in the US. You can redeem PAXG for fractional gold allocation through Paxos directly, though redemption of physical bars still requires a whole-bar threshold of roughly 430 PAXG at current bar sizes. Below that threshold, redemption is processed as a USD cash settlement rather than metal delivery. This is closer to how a gold ETF handles small-holder redemptions than how a bullion dealer would.
Fee reality: Paxos charges an annual storage fee deducted in-kind from the token, meaning your PAXG balance quietly decreases over long holding periods. On-chain transfers pay Ethereum gas. Exchange spreads on PAXG against USD are typically wider than on BTC or ETH, reflecting thinner book depth. Before buying, check the spread against the gold spot price on a reference source such as the LBMA afternoon fix.
