According to @jessepollak, developers who build on Base can reach millions of users on Coinbase, highlighting a direct distribution channel from Coinbase to Base-built applications that could catalyze onchain activity (source: @jessepollak on X). Base operates as an Ethereum Layer-2 and uses ETH for gas, meaning any rise in Base usage directly consumes ETH and settles to Ethereum, a linkage relevant for ETH liquidity and fee dynamics (source: Coinbase Base documentation). Traders should track confirmation via onchain adoption metrics such as daily transactions, active addresses, and TVL on Base to validate follow-through from this distribution message (source: L2Beat methodology and widely used industry analytics standards). There is no Base token, so practical exposure vectors are ETH, Base ecosystem dApps, and Coinbase equity COIN for sensitivity to user engagement and product-driven activity on the exchange (source: Coinbase Base FAQ; Coinbase investor relations for ticker COIN).
