To The Moon

Stablecoins used to be an odd corner of crypto. Now they’re fast becoming the bridge between traditional finance and the blockchain economy. With Ripple’s RLUSD and PayPal’s PYUSD both fighting for investor trust, I wanted to take a closer look at which digital dollar feels safer — and more investable — in today’s regulatory climate. The battle is as much about credibility and adoption as it is about financial mechanics.

Two visions of trust, converging into one digital future

Ripple’s Institutional Edge with RLUSD

Ripple has been unapologetic about where RLUSD fits into its strategy: this is a coin designed for institutions, not retail hype. At $729.8 million in market cap and around 730 million tokens in circulation, RLUSD is still the smaller player compared to PYUSD’s $1.21–$1.39 billion footprint. Yet its liquidity, with trading volumes swinging between $61 million and $184 million in a single day, suggests an unusually active base.

For investors, that volume-to-market cap ratio of 8.46% stands out. It implies RLUSD is being used, not just held. That’s important because one of the big knocks on many stablecoins is that they’re little more than parking spots for arbitrageurs. Ripple’s ability to position RLUSD across XRPL and Ethereum networks adds flexibility, which should help it plug into existing DeFi systems while keeping an institutional door open.

RLUSD punches above its weight with lively trading action

The drawback is regulation. Ripple remains closely associated with past battles with the SEC. Even though RLUSD is marketed as fully backed 1:1 by USD and cash equivalents, its credibility with risk-averse banks will always be influenced by Ripple’s legal baggage. Investors may like the trading metrics, but they’ll need confidence in Ripple’s regulatory diplomacy before treating RLUSD as anything more than a tactical asset.

PayPal’s Consumer Gateway with PYUSD

PayPal’s approach feels more straightforward: build a stablecoin and plug it into an already global payments ecosystem. With a market cap pushing $1.4 billion and a 1:1 redeemability guarantee, PYUSD has the optics of scale and safety. But when you peek under the hood, adoption is surprisingly narrow. Daily trading volumes hover at just $11–$20 million — barely a fraction of RLUSD’s liquidity — giving PYUSD a limp 0.8% volume-to-market cap ratio.

PYUSD stays calm — liquidity steady, volatility contained

That’s a signal worth reading. Despite PayPal’s 400 million active accounts, PYUSD isn’t yet being widely transacted outside of PayPal’s own ecosystem. The coin is listed across 122 markets, but liquidity and decentralised use are shallow compared to what one might expect from a payments titan. In other words, PayPal has distribution, but it hasn’t converted that into active utility.

The positives lie in transparency and oversight. PYUSD is issued by Paxos, a regulated entity, and backed by USD deposits, Treasuries, and cash equivalents, with public monthly reserve reports. In a world scarred by the collapse of unbacked coins, that level of disclosure is a competitive advantage.

Adoption vs Regulation: The Real Contest

The temptation is to frame this battle as David vs Goliath: Ripple’s smaller but agile RLUSD against PayPal’s heavyweight PYUSD. But the reality is more nuanced. RLUSD is gaining traction with institutions that need liquidity and efficiency in cross-border corridors, while PYUSD is leaning on brand credibility and retail distribution.

What most investors don’t realise is that adoption curves for stablecoins don’t simply track market cap. They hinge on network effects and regulatory optics. RLUSD has under 8,000 known holders — but its institutional slant means each holder often represents larger transactional volumes. PYUSD may have wider theoretical reach, yet unless PayPal incentivises usage outside its walled garden, the coin risks becoming more of an accounting novelty than a genuine payments innovation.

Bigger cap, smaller voice: RLUSD trades louder than PYUSD

Both coins are also less volatile than traditional cryptocurrencies, with their one-year ranges (RLUSD $0.963–$1.07, PYUSD $0.948–$1.02) showing tight pegs. But the difference is in credibility: RLUSD’s spike to $1.07 hints at active trading pressure, while PYUSD’s tighter band reflects stability but also subdued activity. Investors who equate stable with boring may not find PYUSD especially lucrative unless PayPal leverages its ecosystem more aggressively.

My Verdict: Two Flavours of Safety

When comparing RLUSD and PYUSD, I don’t see a single outright winner. RLUSD looks livelier, with stronger trading activity and a structural edge in institutional payments. PYUSD looks steadier, with regulated backing and a corporate giant’s balance sheet behind it. Both have merits, both have risks.

Dynamic liquidity meets corporate clarity on the digital scales

If I had to frame it for investors: PYUSD is currently the safer bet for those who prioritise regulatory clarity and transparency. RLUSD, by contrast, shows stronger signs of utility and liquidity, which could make it the higher-upside play once Ripple clears its regulatory baggage.

In other words, PayPal’s PYUSD may be the sensible digital dollar to park in today, but Ripple’s RLUSD is the one to watch if you’re willing to accept a little turbulence for the chance of greater institutional lift-off. In the world of stablecoins, safety comes in two flavours — and investors need to decide whether they prefer their digital dollar dull or dynamic.
