Visa Onchain Analytics Reports Record $1.79 Trillion in Adjusted Stablecoin Volume for June 2026

Visa published its June 2026 stablecoin volume data on Sunday, and the headline figure is $1.79 trillion in adjusted transaction volume, a new record for the platform's Onchain Analytics dashboard, narrowly surpassing the $1.78 trillion set in February. Month-on-month growth from May came in at 63%, and the year-over-year comparison shows 125% growth against June 2025.

The dashboard is powered by Allium Labs, a blockchain data firm that applies filtering to remove bot-driven transactions, exchange treasury rebalancing, and repeated smart-contract cycles before publishing any number. That methodology is what Visa's Head of Crypto, Cuy Sheffield, described in the company's official stablecoin analysis as a recognition that "not all stablecoin volume is created equal." The $1.79 trillion is the clean number; the raw total across all chains is substantially higher.

How Visa and Allium Labs Define Adjusted Stablecoin Volume

The distinction between raw and adjusted volume matters considerably when reading Visa's data. Blockchain stablecoin transfers include a large proportion of activity that does not represent genuine economic settlement: high-frequency arbitrage bots, liquidity provision loops that cycle funds repeatedly through the same contracts, and exchange treasury rebalancing that shuffles funds without any corresponding real-world transaction.

Visa and Allium's adjusted methodology strips those out, attempting to approximate the volume representing genuine payments, remittances, and commerce. Cuy Sheffield called it the organic signal in a network otherwise crowded with automation. The gap between raw and adjusted is significant: an earlier Visa example from their analytics documentation showed a 30-day raw figure of $3.9 trillion reduced to $817.5 billion after adjustment, a reduction of roughly 80%.

That context is relevant when evaluating any absolute comparison of stablecoin volume across chains. Networks with large programmatic DeFi footprints generate more bot activity and are therefore more affected by the filtering.

USDC Claims 67% of June Adjusted Volume

USDC accounted for $1.21 trillion of June's adjusted total, capturing 67% of all activity. USDT took approximately $576 billion, or 32%. PayPal's PYUSD posted $2.42 billion.

The USDC lead reflects both its institutional entrenchment and a period of accelerating issuance on Solana. Circle USDC$1.000+0.0% minted $3.5 billion in USDC on Solana in the most recent week, according to KuCoin reporting, pushing Circle's 2026 gross USDC issuance on Solana to roughly $64 billion. That figure represents cumulative minting, not circulating supply — burns and redemptions reduce the net balance — but the pace of issuance signals where institutional and developer demand is concentrating.

The holder base has expanded alongside issuance. Solana's USDC wallet count rose by 456,000 through June (from 7.17 million on June 6 to 7.62 million by June 30, per Solana Compass data), a 6.4% gain in a single month as new wallets engaged with the stablecoin across DeFi, salary rails, and payment corridors.

As we covered in June, Solana held the top position for USDC transaction count for seven consecutive weeks, with 22.7 million USDC transfers in a single week representing 31.8% of all global USDC transactions. That leadership is in transaction count, not dollar volume: Solana processes more individual stablecoin transfers than any other network, with the stablecoin supply pattern reflecting the ongoing rebalancing from Ethereum toward Solana that has characterized the past several months.

Base Leads Dollar Volume; Visa Cites Solana for Settlement Characteristics

By raw adjusted dollar volume across all stablecoins, according to Visa's Onchain Analytics data, Coinbase's Base Layer 2 topped the June rankings at $565 billion (31.5% of the global total), followed by Ethereum at $562 billion and Tron at $320 billion (roughly 18% of the total). Those three networks together account for approximately 80% of June's adjusted stablecoin activity.

The Base and Ethereum figures are predominantly USDC, given the stablecoin's deep penetration across both networks. Tron's 18% reflects its dominant position in USDT transfers, particularly across emerging markets where Tether has historically been the preferred dollar substitute.

Solana's position in the overall dollar ranking is not specifically broken out in the Visa/Allium data. What the data does reflect is a network where transaction frequency is high and transaction size is, on average, smaller — the profile of salary payments, retail P2P transfers, and frequent micro-settlement rather than large institutional wire-style flows. That is a different use case from Base's USDC concentration, not a lesser one.

Visa's Own Settlement Pilot Runs on Solana at $7 Billion Annualized

The data's significance for Solana is not only what the numbers show; it is also what Visa has built on top of the network. Visa launched stablecoin settlement in the United States in December 2025, letting partner banks — Cross River Bank and Lead Bank — settle VisaNet obligations in USDC directly over Solana. By November 2025, the pilot was running at $3.5 billion annualized; by April 2026, that figure had grown to $7 billion, per reporting from CryptoBriefing.

That makes Visa simultaneously the operator of this analytics dashboard and a participant in Solana's settlement infrastructure. The perspective piece authored by Sheffield notes that the adjusted methodology was developed in part because Visa needed a credible way to measure whether blockchain rails were carrying genuine economic activity — the kind that could eventually be relevant to their own payment volume. The June figure suggests those rails are.

$10.2 Trillion in Trailing Volume Signals Category Maturation

The cumulative 12-month adjusted stablecoin total has now reached $10.2 trillion, per Visa's Onchain Analytics dashboard. That number, divided across a full year, implies average monthly adjusted volume of roughly $850 billion — meaning June's $1.79 trillion is more than double the annual average rate, reflecting either accelerating adoption or seasonal concentration, likely both.

The broader context, per the same dashboard: the total stablecoin market cap stands at $322 billion. That capital base generated $1.79 trillion in adjusted transfers in June alone — a velocity ratio that describes a settlement layer turning over its supply approximately 5.5 times per month in genuine economic activity.

Nick Ruck, director of research at LVRG Research, framed it this way in comments to CoinTelegraph: "This surge underscores the growing role of stablecoins as essential infrastructure for value transfer, liquidity provision, and decentralized finance activity."

The previous record, from February, stood for four months. The pace at which the stablecoin settlement category is growing means new benchmarks are becoming harder to interpret as surprises.

For Solana, the Visa data is a third-party confirmation of a trend the network's own metrics have been showing: real-economy stablecoin settlement, measured by transaction frequency and the types of flows (salaries, retail P2P), is concentrating on the network with the lowest per-transaction cost. Solana's USDC supply passed 10% of global issuance in June; the Circle minting pace since then has kept that share elevated. Whether the trend extends into dollar-volume leadership (not just transaction count) will be what subsequent Visa monthly releases show.
