Uniswap ranks as top DEX for stablecoin trading ahead of Arc launch
Uniswap has quietly turned itself into the dominant venue for stablecoin-to-stablecoin swaps across EVM-compatible chains, processing 57% of that trading volume. That’s up from 43% at the start of the year.
The timing isn’t accidental. Circle’s Arc, a Layer-1 blockchain purpose-built for stablecoin applications, is set to launch its public mainnet on September 16. Uniswap will be there from day one, providing swap infrastructure and liquidity on a chain that counts BlackRock, Visa, and Mastercard among its founding validators.
The numbers behind Uniswap’s stablecoin dominance
Uniswap’s cumulative trading volume has now surpassed $4.4 trillion. The protocol’s stablecoin market share has grown by 14 percentage points in a matter of months.
Uniswap’s integration with Arc, announced around mid-June 2026, locks in that advantage on an entirely new chain. Rather than waiting for organic liquidity to develop, Arc gets access to battle-tested automated market maker technology immediately.
What Arc actually is, and why institutions care
Arc is designed specifically for stablecoins, real-time payments, tokenization, and institutional finance. USDC serves as Arc’s native gas token, which means every transaction on the chain is denominated in dollars rather than a volatile cryptocurrency.
The founding validator set includes BlackRock, DTCC, Visa, Mastercard, and Standard Chartered. BlackRock has plans to deploy its BUIDL tokenized fund on Arc using native USDC.
Over 100 builders are already active on Arc’s private mainnet as of August 2026. Aave and Aerodrome are among the early participants, meaning Arc will launch with lending, borrowing, and liquidity protocols already operational.
What this means for investors
The UNI token has responded to these developments with a notable rally, reflecting investor anticipation around what the Arc integration could mean for Uniswap’s revenue and volume metrics.
There’s also the competitive angle. Uniswap isn’t the only DEX that could serve stablecoin markets. Aerodrome, already confirmed as an Arc participant, could compete for the same liquidity.
For traders and liquidity providers, the Arc launch creates a concrete catalyst to watch. September 16 will reveal whether the institutional validators actually drive meaningful volume. The gap between Uniswap’s current 57% stablecoin dominance and whatever share it captures on Arc will tell investors whether the protocol’s moat travels across chains.

$3.7 billion “data center power equipment prepayments” abandoned! What did "the most active buyer of gas turbines", SoftBank, see?
In the second quarter of fiscal year 2026, SoftBank reported a net loss of $7.1 billion, primarily due to a $3.7 billion impairment charge from a $9.5 billion advance payment for power generation equipment for US data centers—of which about $2.9 billion was non-refundable and effectively lost. The CFO admitted that SoftBank placed orders before the project plan was finalized, and is now conducting a comprehensive review of its procurement strategy. "The most aggressive purchaser of gas turbines has now written off the deposit in this way."
