ETH/USDC is Uniswap's largest and most efficient market not because of its own pair demand alone, but because almost all other swap routes flow through it as a bridge pair.

Cash App's stablecoin integration is cited as the gold standard for seamless UX, abstracting away blockchains, gas fees, and pricing entirely when sending USDC from a dollar balance.
“The gold standard for that experience that happened a few weeks ago is like Cash App did their integration of stable coins where like you actually do not even deal with the like the blockchains or gas fees or any sort of pricing at all in order to transfer USCC out from your dollar balance on Cash App.”Kendall Cole · 16 Jul 2026
Correlated asset pairs (such as Nvidia and SPY) generate more AMM liquidity than a single asset against a stablecoin, because tighter correlation reduces impermanent loss and attracts more liquidity providers.
“It's actually something like Nvidia and SPY that are the correlated pairs and they become much more liquid than say just Nvidia and USDC.”Ryan Sean Adams · 21 Aug 2026
