Key Takeaways:
Coinbase's Layer 2 network has stacked up roughly $4 billion in total value locked, capturing the lead in onchain BTC and ETH spot trading while processing the bulk of USDC payment flows.
Base, Coinbase's Ethereum Layer 2 network, has accumulated about $4 billion in total value locked, leading all L2 competitors in onchain BTC and ETH spot trading volumes.
"Base's USDC concentration — 89% to 90% of its stablecoin supply — creates a payments flywheel that competing L2s haven't matched," according to DefiLlama data tracking the network's stablecoin composition.
The network now ranks second across all DeFi chains in lending TVL, driven primarily by Morpho, a capital-efficient lending protocol that has facilitated over $1.5 billion in flows. On the trading side, Aerodrome operates as Base's liquidity hub using a vote-escrow model, capturing leading market share for onchain BTC and ETH spot trading among L2s. cbBTC, Coinbase's wrapped Bitcoin product, has crossed $1.5 billion in integrations on Base.
Base's dominance reinforces the Layer 2 thesis but introduces a single-point-of-failure risk: the network's 89% to 90% USDC concentration means any regulatory constraint on Circle would hit Base disproportionately compared to chains with more diversified stablecoin ecosystems.
The USDC Engine Driving Base's Growth
Stablecoin volumes processed on Base have reached multi-trillion dollar figures, with USDC accounting for nearly all of the network's stablecoin supply. The Circle-issued stablecoin's deep integration stems from Coinbase's role as a co-founder of the Centre consortium that originally governed USDC. That merchant channel became tangible in June 2025, when Shopify integrated USDC payments on Base, giving businesses a direct on-ramp to accept crypto without Bitcoin or Ethereum settlement volatility. More recently, Travala introduced agentic AI payment systems on Base, enabling gasless USDC transfers — a milestone that moves crypto payments closer to mainstream consumer finance.
Trading and Lending: Where the TVL Lives
Aerodrome's vote-escrow model lets token holders direct where trading incentives flow, creating a self-reinforcing liquidity loop that has made Base the go-to chain for spot trading major crypto assets. The BTC trading story got a meaningful boost from cbBTC, whose $1.5 billion-plus integration on Base gives traders Bitcoin exposure without leaving the Ethereum ecosystem. On the lending side, Morpho's approach matches lenders and borrowers more directly than traditional pool-based models, optimizing capital efficiency. The protocol has channeled over $1.5 billion in capital flows through Base.
The network's growth is partially tethered to Coinbase's user acquisition funnel, which funnels retail users directly onto Base. For DeFi participants, the lending opportunity deserves attention: Morpho's capital efficiency model combined with Base's deep USDC liquidity creates conditions for competitive yields, while the 89% to 90% USDC concentration means less exposure to depegging risk from smaller stablecoins.
The ETH/BTC ratio's plunge to about 0.0265 — a level not seen since 2016 — shows the structural shift in market preferences, with Bitcoin benefiting from institutional ETF flows while Ethereum faces headwinds from L2 fee cannibalization and competition from alternative Layer 1 blockchains.
