Question 1

What is USDP, and what does its 1:1 mechanism mean?

Accepted Answer

USDP (Pax Dollar) is a USD-denominated, USD-backed stablecoin managed by Paxos Trust Company, N.A. Its core design is that USDP in circulation is supported by reserves of cash and cash equivalents, and eligible Paxos customers can redeem it with Paxos at a rate of 1 USDP for 1 U.S. dollar. Here, “1:1 redemption” refers to the issuer's redemption arrangement; it does not mean that USDP will necessarily trade at exactly 1 U.S. dollar at every moment in any secondary market. Secondary-market prices are also affected by factors such as venue liquidity, order books, and transfer costs.

Question 2

How is USDP supported by reserves?

Accepted Answer

USDP's reserve arrangement is the basis for its redemption mechanism: Paxos states that reserves are held in cash and cash equivalents and correspond to USDP in circulation. It publishes monthly attestation reports for users to review reserve disclosures. Reserve backing addresses whether the issuer has the asset basis to fulfill redemptions according to its rules; it cannot eliminate all risks of use. For example, when users sell on a third-party market, they face that market's quotes and liquidity rather than directly triggering Paxos's redemption process.

Question 3

How can USDP be exchanged for U.S. dollars through Paxos?

Accepted Answer

Yes, but this is a direct redemption process Paxos provides to its customers, rather than an on-chain function automatically available to all holders. Customers need a Paxos account and must send USDP to the dedicated redemption address specified for this type of stablecoin in that account; Paxos then credits the corresponding U.S. dollar amount to the account at 1:1. Redemption requests are subject to compliance review and may have a minimum amount; token amounts are rounded down to the nearest cent. When U.S. dollars are withdrawn from the platform account, the receiving bank account must be designated and owned by that customer, and processing time may also be affected by compliance procedures, banks, and regional conditions.

Question 4

Which networks does USDP support, and why must the network be confirmed when transferring?

Accepted Answer

USDP is currently available on Ethereum and Solana. Before sending, the sender and recipient must confirm they are using the same supported network and the correct address for that network; assets with the same name on different networks are not automatically interoperable. The network determines the native Gas asset required for on-chain transfers, the confirmation method, and the address format; it does not change USDP's issuer redemption terms. Sending tokens to an incompatible network or an address that does not support the asset may be unrecoverable.

Question 5

How can USDP be used?

Accepted Answer

USDP can be used to hold and transfer digital dollars on networks that support it, make payments to parties willing to accept USDP, and trade or exchange it in services that offer the asset. Holding, transferring, and paying are token functions; whether a particular service can be completed also depends on support from the recipient, platform, and region. On-chain transfers are generally irreversible once confirmed, so the network, address, and amount should be checked before initiating a transfer. Direct subscription or redemption with Paxos and buying or selling on third-party venues are also different routes: the former is subject to Paxos customer and compliance rules, while the latter is subject to the relevant service provider's rules and market quotes.

Question 6

What limitations and risks should be prioritized when using USDP?

Accepted Answer

When using USDP, issuer redemption, on-chain operations, and third-party services should be assessed separately. Direct redemption depends on the customer account, location, compliance review, minimum amount, and account status; Paxos's terms also allow it to deny or restrict related services in certain circumstances. At the on-chain level, users must bear the consequences of errors in address and network selection, Gas fees, and irreversible transfers; when using USDP on trading platforms or in other services, they are also affected by that service's liquidity, withdrawal rules, and counterparty risk. A stablecoin's peg target cannot replace these conditions.
