TL;DR:
- Adjusted stablecoin transaction volume reached a record $1.79 trillion in June, up 63% from May and 125% year over year.
- USDC dominated adjusted activity with $1.21 trillion, or about 67%, while USDT represented $576 billion and PYUSD reached $2.42 billion.
- Base led networks with $565 billion, narrowly ahead of Ethereum’s $562 billion, as filtered methodology highlighted organic stablecoin use across payments, DeFi and cross-border transfers during the current market cycle.
Adjusted stablecoin transaction volume climbed to a record $1.79 trillion in June, according to Visa’s Allium-powered analytics dashboard, creating a striking counterpoint to broader crypto-market weakness. The figure rose 63% from May’s $1.1 trillion, edged past February’s prior $1.78 trillion high and stood 125% above the year-earlier period. For a sector once treated mainly as trading plumbing, stablecoins are now showing payment-scale velocity, with activity spreading across payments, decentralized finance and cross-border transfers even as speculative sentiment remains pressured. That resilience makes the record feel less like noise and more like a structural signal now.

USDC, Base and Ethereum dominate the stablecoin map
The composition of that volume is just as revealing. USDC accounted for about 67% of June activity, or $1.21 trillion, even though USDT remains the largest stablecoin by market capitalization. USDT represented roughly 32%, or $576 billion, while PayPal’s PYUSD ranked third by transaction volume at $2.42 billion. The contrast is awkward but useful: market cap leadership does not automatically translate into settlement leadership. In June, the busiest stablecoin flows were concentrated around the asset most used for adjusted transaction activity, not the token with the largest headline supply overall.
Network distribution added another layer to the maturity story. Coinbase’s Ethereum layer-2 network Base processed $565 billion in stablecoin transactions, equal to 31.5% of the total, narrowly ahead of Ethereum’s $562 billion. Tron ranked third with $320 billion, or about 18%. Visa’s methodology, developed with Artemis, Allium Labs and Castle Island Ventures, filters out high-frequency trading bots, exchange treasury rebalancing and repeated smart contract transactions. The measurement is trying to separate organic usage from mechanical churn, which matters when volume records can otherwise exaggerate activity.
The broader interpretation is that stablecoins are moving from speculative sidecar to core transaction layer. Nick Ruck, director of LVRG Research, said the record shows their resilience during a broader bear market and reflects their role in value transfer, liquidity provision and DeFi activity independent of price speculation. He expects the trend to continue as stablecoins mature into a foundational Web3 layer. The next question is durability, because June’s record suggests momentum, but sustained adoption will depend on whether real-world payments, liquidity demand and cross-border use keep compounding beyond one standout month across networks, issuers and institutional workflows throughout the next cycle.
