Base, Coinbase’s Ethereum Layer 2 network, has stacked up roughly $4 billion in total value locked and turned itself into the go-to chain for spot trading major crypto assets. The network now leads Layer 2 competitors in onchain BTC and ETH trading volumes while processing the lion’s share of USDC payment flows.

Base simultaneously ranks second across the broader DeFi landscape in lending TVL, a metric that measures how much capital is parked in borrowing and lending protocols.

The USDC engine driving Base’s dominance

Base’s growth story is almost entirely denominated in USDC. The Circle-issued stablecoin accounts for 89-90% of the total stablecoin supply on the network.

Coinbase and Circle share deep roots, with Coinbase being a co-founder of the Centre consortium that originally governed USDC.

That merchant angle became real in June 2025, when Shopify integration for USDC payments rolled out on Base. The move gave businesses a direct on-ramp to accept crypto without dealing with the volatility headaches of BTC or ETH settlement.

More recently, Travala introduced agentic AI payment systems built on Base, enabling gasless USDC transfers. When an AI agent can execute a payment without the user ever thinking about gas fees, you’ve crossed from crypto-native tooling into something that resembles actual consumer finance.

Stablecoin volumes processed on the network have reached multi-trillion dollar figures.

Trading and lending: where the TVL lives

On the trading side, decentralized exchanges on Base, led by Aerodrome, have captured leading market share for onchain BTC and ETH spot trading among Layer 2 networks. Aerodrome operates as a liquidity hub using a vote-escrow model, which means token holders direct where trading incentives flow.

The BTC trading story on Base got a meaningful boost from cbBTC integrations, which have crossed the $1.5 billion mark. cbBTC is Coinbase’s wrapped Bitcoin product, and its deep integration with Base means traders can access BTC exposure without leaving the Ethereum ecosystem.

Lending rounds out the trifecta. Protocols like Morpho are the primary engines behind Base’s second-place ranking in lending TVL across DeFi. Morpho’s approach optimizes capital efficiency by matching lenders and borrowers more directly than traditional pool-based models. The protocol has facilitated capital flows exceeding $1.5 billion.

What this means for investors

For DeFi participants, the lending opportunity on Base deserves a closer look. Morpho’s capital efficiency model combined with the chain’s deep USDC liquidity creates conditions for competitive yields. The 89-90% USDC concentration also means less exposure to depegging risk from smaller, less battle-tested stablecoins.

Base’s advantage is its Coinbase distribution channel, which funnels retail users directly onto the network, but it also means Base’s growth is partially tethered to Coinbase’s own user acquisition trajectory.

One risk that rarely gets discussed: the USDC concentration that makes Base so effective for payments also creates a single point of regulatory exposure. If Circle faces constraints in any major jurisdiction, Base feels the impact disproportionately compared to chains with more diversified stablecoin ecosystems.
