Coinbase reported an 11 percent quarter-over-quarter decline in its "other" transaction revenue during the second quarter. The segment, which includes revenue from its Layer 2 network Base, reached $47.4 million, according to the company's Q2 earnings presentation filed Thursday. The drop came despite Base processing more stablecoin volume than any other blockchain during the period.
Base, launched in August 2023 on the Optimism OP Stack, has expanded its user base and TVL rapidly since inception. The divergence between stablecoin volume leadership and falling revenue points to fee compression—lower gas prices on the network, intensifying L2 competition and Coinbase's deliberate strategy of keeping transaction costs low to drive user acquisition.
Revenue for L2 operators flows primarily from sequencer fees. Sequencers batch transactions on the Layer 2 and submit them to Ethereum for final settlement, with the fees charged constituting the operator's direct revenue stream. As an OP Stack chain, Base routes a portion of that sequencer revenue to the Optimism Collective to fund ongoing development of the underlying stack.
Base's stablecoin volume surpasses Arbitrum, Optimism mainnet and several Layer 1 networks with established stablecoin ecosystems. High throughput signals active DeFi usage across the network—but volume alone does not translate to sequencer revenue if per-transaction fees are thin.
Arbitrum and Optimism compete directly for stablecoin liquidity and user activity, using different approaches: Arbitrum has distributed ARB tokens to bootstrap liquidity, while Optimism's Retroactive Public Goods Funding model allocates OP tokens to ecosystem contributors.
Coinbase's longer-term monetization case for Base rests on higher-value activity—tokenized real-world assets, lending markets and enterprise applications—rather than the low-margin stablecoin transfers currently driving volume. The "other" transaction revenue segment is a small slice of Coinbase's total revenue, which is primarily driven by retail and institutional trading fees.
The Q2 earnings presentation positions Base as infrastructure rather than a near-term revenue driver, with network utility and user adoption as the metrics Coinbase is optimizing for now.
