What is USDP: Understanding the Stablecoin Backed by US Dollar Deposits

Paxos's Positioning and Significance

In 2018, Paxos launched Paxos Standard (PAX), later renamed to Pax Dollar (USDP), aiming to solve the lack of regulatory compliance and transparency in the stablecoin market.

As the world's first regulated stablecoin, USDP plays a crucial role in providing a stable, fully backed digital asset for crypto trading and settlements.

As of 2025, USDP has become a trusted stablecoin in the cryptocurrency ecosystem, with significant trading volume and widespread adoption. This article will analyze its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

USDP was created by Paxos in 2018 to address the need for a fully regulated and transparent stablecoin in the crypto market.

It was born during the growing demand for stable digital assets in cryptocurrency trading, aiming to provide a reliable, 1:1 USD-backed digital alternative to cash for instant transaction settlements.

USDP's launch brought new possibilities for crypto traders, exchanges, and institutions seeking a compliant stablecoin solution.

Important Milestones

• 2018: Launched as Paxos Standard (PAX), offering full regulatory compliance and 1:1 USD backing.
• 2021: Rebranded from PAX to Pax Dollar (USDP), reinforcing its position as a dollar-backed stablecoin.
• 2021: Adopted by major crypto platforms, driving wider acceptance in the crypto ecosystem.
• 2023: Expanded use cases in DeFi and cross-border payments, solidifying its role in the digital asset space.

With support from the Paxos company and regulatory oversight, USDP continues to enhance its technology, security, and real-world applications.

How Does USDP Work?

No Central Control

While USDP operates on the Ethereum blockchain, its issuance and redemption are managed by Paxos, a regulated financial institution.

This hybrid model combines the benefits of blockchain technology with regulatory compliance, offering users a stable and trustworthy digital asset.

Blockchain Core

USDP utilizes the Ethereum blockchain as its underlying technology, leveraging its security and transparency.

Transactions are recorded on this public, immutable digital ledger, grouped into blocks and linked through cryptographic hashes.

Anyone can view the records, establishing trust without intermediaries.

Ensuring Fairness

As an ERC-20 token on Ethereum, USDP relies on Ethereum's Proof-of-Stake (PoS) consensus mechanism for transaction validation.

Ethereum validators maintain network security through staking and running nodes, indirectly supporting USDP transactions.

USDP's innovation lies in combining this decentralized infrastructure with centralized issuance and redemption processes overseen by regulators.

Secure Transactions

USDP uses public-private key encryption for transaction security:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous on the blockchain.

Additionally, Paxos implements strict KYC/AML procedures for USDP issuance and redemption, adding an extra layer of security and compliance.

New tokens enter the market through user purchases and redemptions, directly impacting supply and demand dynamics.
