According to the source, PayPal is deploying stablecoins and blockchain to streamline global payments, led by PayPal USD (PYUSD), an ERC-20 token on Ethereum issued by Paxos and fully backed with monthly reserve attestations to support fast, low-friction value transfer for users and merchants (source: PayPal Newsroom; source: Paxos). In the PayPal and Venmo apps, eligible U.S. users can buy, hold, send PYUSD, transfer it to external Ethereum wallets, convert between PYUSD and supported cryptocurrencies, and fund purchases by converting PYUSD to dollars at checkout, expanding stablecoin utility within a large payments network (source: PayPal Newsroom). Because PYUSD settles on Ethereum, transactions require ETH for gas and interoperate with Ethereum infrastructure, making ETH network costs and throughput directly relevant when assessing PYUSD payment activity and liquidity implications for traders (source: PayPal Newsroom; source: ethereum.org).
