What is PayPal USD (PYUSD)?

PayPal USD is a dollar stablecoin that PayPal commissioned and Paxos Trust Company issues. The distinction matters more than it sounds: PayPal is the brand and the distribution, Paxos is the regulated entity that holds the reserves, mints the tokens and answers to the New York Department of Financial Services. If you are assessing counterparty risk, Paxos is the counterparty.

Each token is a claim on one dollar, redeemable through PayPal or directly with Paxos. The reserve is held in cash, US dollar deposits and short-dated US Treasuries — instruments chosen so the backing can be sold at par on a day's notice rather than for the yield they produce. That yield, which on a $2.8bn float is substantial at current rates, accrues to PayPal and Paxos, not to holders. What holders get instead is the rewards programme, and that is a separate, discretionary promise rather than a pass-through of interest.

Where it actually lives

PYUSD launched on Ethereum in August 2023 and added Solana in 2024. By September 2026 it also circulates on Arbitrum, Flow, Polygon and Sei, most of those reached through LayerZero's omnichain messaging rather than native issuance. The split is lopsided: roughly $1.64bn on Ethereum, $735m on Solana, $320m on Arbitrum and $69m on Flow.

That distribution tells you what the token is for. The Ethereum balance is DeFi collateral and treasury float; the Solana balance is payments and trading where fees are low enough for it to make sense. Very little of PYUSD sits idle in PayPal consumer wallets by comparison.

Three uses account for nearly all of it, and they pull in different directions.

• Consumer balance inside PayPal and Venmo, where it earns the rewards rate and can be spent at PayPal checkout. This is the use PayPal advertises and the smallest of the three by value.
• Creator and merchant payouts. YouTube now lets US creators in the Partner Program — 1,000 subscribers and 4,000 watch hours — take their earnings in PYUSD through PayPal, with PayPal handling custody and conversion so YouTube never touches crypto.
• DeFi collateral on Ethereum, where PYUSD is listed on the major lending markets. This is where most of the supply sits and where the token behaves least like a payment instrument.

The strategic logic is that a stablecoin PayPal controls settles faster and costs less than the card rails PayPal currently rents. Whether that materialises depends on merchants accepting it, and merchant acceptance is the part that has moved slowest.

There is no emission schedule, no cap and no unlock calendar: tokens are minted when someone buys and burned when someone redeems, so supply is a demand gauge rather than a monetary policy. Reading it as one is the most useful thing you can do with this chart.

And the read is not flattering. Supply crossed $4bn in early 2026 and has fallen roughly 35% to about $2.78bn by September. A stablecoin shrinking by a third in nine months is not losing its peg — it is losing holders, generally to competitors paying more, or to holders who took the rewards rate while it was above what Treasuries paid and left when the gap closed.

Set against USDT's and USDC's scale, PYUSD is a small float with a very large distribution channel attached. The bull case has always been that the channel eventually fills the float. Three years in, the float is going the other way.

PYUSD is not staked — there is nothing to secure and no validator set. What exists is a rewards programme, and the difference is worth being precise about because the two are often described with the same word.

PayPal introduced rewards in April 2025 at an advertised 3.7% annual rate; as of September 2026 the advertised rate is 4%. It accrues on the average daily PYUSD balance held in the PayPal or Venmo app and pays monthly, in PYUSD. It is explicitly variable and PayPal can change it at any time.

Two things follow. First, the rate is a marketing budget, not a yield: it is paid out of PayPal's decision to buy adoption, funded by the reserve interest PayPal and Paxos keep. When the calculation changes, so does the rate, with no notice owed to anyone. Second, it only applies to the balance inside PayPal's own apps — move PYUSD to a self-custody wallet or a lending market and you leave the programme, which is precisely the trade-off facing the DeFi majority of the supply.

The minting incident, and what it actually showed

In October 2025 a decimal error during an internal transfer caused Paxos to mint $300 trillion of PYUSD on Ethereum — a figure close to twice global GDP. Paxos identified it and burned the tokens within about twenty minutes, and no customer funds were lost. Aave froze its PYUSD markets while it worked out what had happened, and the NYDFS took an interest.

Nobody lost money, which is the reason it is usually written off. The thing worth keeping is what it demonstrated: the supply of this token is one operational control away from arbitrary, and the control that failed was an internal transfer procedure at a regulated trust company. Every protocol that lists PYUSD as collateral inherits that.

Concentration and redemption

One issuer mints it, one company distributes it, and the reserve sits with that issuer. There is no diversification of the kind a basket or a decentralised design provides. A redemption at scale depends on Paxos selling short-dated Treasuries into a functioning market and on PayPal's own payment rails staying up, and those two dependencies are not independent of each other in a genuine stress.

The rewards rate is the demand

Most consumer holding of PYUSD exists because of a 4% rate PayPal chose to pay and can withdraw. Supply has already fallen a third from its peak with that rate in place. Model what the float looks like if the rate goes to 1%, because that decision belongs to PayPal alone and needs no one's agreement.

Regulatory position

This is the one area where PYUSD is comparatively strong. Paxos operates under a New York trust charter and the GENIUS Act, signed in July 2025, gave payment stablecoins a federal framework. PYUSD is closer to being a regulated instrument than most of what it competes with — which cuts both ways, since a regulated issuer can also freeze an address on instruction.
