Base passes Ethereum in stablecoin volume: crypto payments are moving
“Ethereum is losing ownership of crypto payments as Base moves $565B in stablecoins,” according to Visa Onchain Analytics for June. I’ll be honest: that framing sounds a little too clean. Ethereum has not lost the plot overnight. But Base moving roughly $565 billion while Ethereum sat at about $562 billion is not a rounding error investors can ignore.
“Stablecoin activity has become a fierce contest for which blockchains move the most tokenized dollars,” and June’s data shows how tight that race has become. Visa put adjusted stablecoin transaction volume at about $1.79 trillion for the month, above the February peak and well above May. Base led with roughly $565 billion. Ethereum followed at about $562 billion. The gap is tiny. A $3 billion lead sounds enormous in equities, payments, or banking. Here, against more than half a trillion dollars on each network, it is basically a photo finish.
“Base’s lead over Ethereum is small, but it still matters,” partly because Base is an Ethereum Layer 2 built for cheaper, faster activity. Most guides say lower fees are the whole story. That is only half right. Payments need at least four things to work outside crypto-native circles: wallets, low fees, useful apps, and settlement that holds up when users actually need it. Visa’s adjusted methodology, built with Allium and other partners, tries to filter out bots, high frequency wallets, and internal smart contract movements. Why does that matter? Because raw onchain volume has fooled people before. Plainly: it tries to strip out the noise and keep the activity that looks like real settlement. My take: investors have seen enough inflated onchain numbers dressed up as adoption.
“The issuer split within this volume reinforced USDC’s role in stablecoin settlement,” especially on Base. Visa’s data says USDC made up roughly 67% of June’s adjusted volume, while USDT made up about 32%. So yes, USDC is carrying a lot of the load here. The more interesting part is where the volume is going. Visa describes stablecoins as payment infrastructure for cross border transfers and stablecoin linked cards. It also points to corporate payouts and seven day settlement. If that is the use case, the chain underneath counts. Fees count. Wallet reach counts. App support counts. Is this just plumbing? Mostly, yes. But payment plumbing is exactly where value accrues when usage becomes boring and frequent. If stablecoins still feel awkward outside trading apps, nobody will care how clean the chart looks.
“Visa’s insights had already pointed to a longer Layer 2 trend,” and June makes that trend harder to dismiss. Visa’s earlier reports said L2 networks collectively passed Ethereum in monthly stablecoin transaction count in August 2024. Base also saw fast USDC growth after launching in 2023. Now the same pattern is showing up in adjusted dollar volume. I would not call this a permanent takeover yet. This is not settled. Counter to the usual advice, the main signal is not simply “watch Base.” The better signal is whether users keep drifting toward cheaper rails for stablecoin transfers when markets are hot, quiet, or stressed. For ETH holders, that raises an uncomfortable question. Ethereum is still the base layer, but if everyday stablecoin activity moves to L2s, ETH’s story may lean more on security and settlement than on mainnet fees from routine transfers. That could affect ETH’s price if the market starts assuming a lot of stablecoin use will skip mainnet.
“That said, the lead remains narrow,” and narrow really does mean narrow. Base beat Ethereum by only about $3 billion, while both networks cleared more than half a trillion dollars in adjusted volume. Ethereum is not disappearing. Base is just close enough to make the old assumptions feel dated. Traders should watch L2 ecosystems, including Base and Optimism. Arbitrum belongs on the same watchlist too. Payment volume tends to pull in attention, then liquidity, and eventually speculation. Yes, this slightly contradicts the “Base matters” point above. Bear with me: the point is not that Base alone wins, but that L2 settlement is becoming harder to treat as secondary. The “Ethereum killer” line still feels overdone to me. “Ethereum extender” fits better, and Base is making that version easier to believe.
What this means
“This data points to stablecoin utility moving toward Layer-2 networks because they are cheaper and faster,” based on Visa’s Onchain Analytics. For Ethereum, that may mean less focus on being the direct payment layer and more focus on being the secure base layer underneath it. The short term risk is easy to see: if investors tie ETH’s value too closely to high mainnet fees, L2 growth can look like dilution. The longer view is messier. L2 growth also shows Ethereum’s scaling plan working, which could support ETH if the market gives credit to the whole ecosystem instead of only mainnet activity. That is the catch.
“Investors should watch whether stablecoin volume keeps moving to L2s across more than one month and across different market conditions,” because one strong June does not settle this. Track Visa’s adjusted stablecoin volumes for Base, Arbitrum, Optimism, and other major L2s. If Base keeps leading, or if other L2s start taking more share, the market will probably get louder about L2s becoming the default settlement layer for stablecoins. New L2s and their tokens are worth watching too, but only if they win real volume, not just incentives and launch week hype. What is the next useful signal? Simple: payment-like stablecoin flows need to stay on L2s for several months, especially if new stablecoin rules push users toward faster, lower cost networks.
