By 2026, stablecoin networks are poised to present a significant alternative to established cross-border payment systems. Current data reveals that monthly on-chain settlements, denominated in dollars, have already surpassed trillions, and expanding merchant accessibility through major payment processors is accelerating this trend.
According to RWA.xyz’s real-time data panel, stablecoins facilitated approximately $3.3 trillion in on-chain transactions during July. This activity involved nearly 39.7 million unique active addresses monthly, while the total value held in stablecoins hovers around $259 billion.
The potential for stablecoins to rival traditional systems hinges on several key developments. Firstly, payment accessibility is improving. For example, Stripe has reintroduced crypto payment options, beginning with USDC on Solana, Ethereum, and Polygon. This integration returns stablecoins to standard online checkout processes, with further feature expansions planned for 2025.
Coinbase and PayPal have also taken steps to promote adoption, including waiving fees on PYUSD conversions since April 24th. This allows merchants to receive payments in PYUSD instead of relying on conventional card networks.
Secondly, off-ramp costs on Ethereum Layer 2 solutions are decreasing thanks to the Dencun upgrade and the increased data capacity of the Pectra update. According to Galaxy’s analysis following the 4844 update, and subsequent blob market reviews, these changes have reduced median rollup transaction costs to mere cents. Real-time fee trackers further demonstrate that transfers on leading Layer 2 networks are often available for less than ten cents.
Thirdly, the attractive yields offered by tokenized U.S. Treasury bills (T-bills) are drawing interest from both treasury departments and fintech companies. Data from RWA.xyz’s Treasuries dashboard indicates the on-chain value of T-bills is approximately $7.0 billion. Securitize has also reported that BlackRock’s BUIDL fund has exceeded $3 billion in assets under management (AUM) as of June.
Proper comparison is vital. Visa’s 2024 report indicates a total payment and cash volume of $16 trillion, whereas SWIFT documents mention approximately $300 billion daily on their global payments innovation (gpi) network for capital market transactions. This illustrates how traditional networks aggregate large-value transfers from diverse use cases.
Modeling future stablecoin payments
Direct comparisons between stablecoin payments and traditional systems are not straightforward. Therefore, examining potential scenarios provides a more helpful perspective on a possible crossover by 2026 than merely comparing raw totals.
A simplified predictive model, based on identifiable driving factors, suggests a potential settlement range of $3 trillion to $5 trillion for stablecoin payments by 2026.
This projection assumes a 2% to 3% monthly growth in active addresses as merchant integration expands through Stripe and PYUSD conversions without fees. It also factors in an average payment amount between $400 and $1,200 as remittance and business-to-business (B2B) use cases normalize, increased adoption of off-ramps to mainstream accounts through processors and exchanges, and Layer 2 costs remaining near post-Dencun levels.
| Scenario | Active Addresses (M) | Txs/User/Month | Avg Transfer ($) | “Clean” Share (%) | Annual Transfer Volume ($T) | Annual Settlement ($T) |
|---|---|---|---|---|---|---|
| Conservative | 80–100 | 2–3 | 300–600 | 25–40 | 4.0–6.8 | 0.4–1.7 |
| Base Case | 120–150 | 3–4 | 500–900 | 35–55 | 7.0–12.9 | 2.0–5.0 |
| Aggressive | 150+ | 4–5 | 800–1,200 | 50–65 | 14.0–21.6 | 5.0+ |
Applying a reduction to account for internal exchange activity, followed by scaling for monthly activity and a 10% to 20% cash-out rate, suggests that annual end-user settlement could reach $3 trillion in a base-case scenario and potentially exceed $5 trillion if address growth and average transfer amounts increase in tandem.
Remittance costs also present an opportunity, with the World Bank’s Remittance Prices Worldwide (RPW) reporting a global average cost of 6.26% as of March 27th. This leaves room for stablecoin networks to offer competitive advantages in terms of price, speed, and transparency.
Broader economic trends support this growth. The U.S. GENIUS Act, now enacted, requires that stablecoins maintain fiat-backed reserves and provide monthly disclosures, bolstering the credibility of dollar-denominated stablecoins and, subsequently, the demand for the short-term Treasury securities backing many of these tokens.
Regarding costs, Galaxy’s research indicates that rollup fee revenue decreased while margins improved following the 4844 update, suggesting continued low fees for end-users as network capacity expands.
Concerning acceptance, PayPal reports tens of millions of merchant relationships in company filings and industry data, which, coupled with Stripe’s reentry into stablecoin payments, extends distribution beyond solely crypto-focused channels.
The potential for a stablecoin crossover by 2026 does not necessarily mean replacing SWIFT or credit cards entirely. Instead, it’s about stablecoins dominating specific use cases where speed, cost, and round-the-clock settlement are paramount. This is facilitated by significant on-chain transaction volumes, lower fees because of Layer 2 upgrades, and increasing adoption by merchants and treasuries as regulatory clarity emerges.
