Base, the Layer 2 network incubated by Coinbase and built on the OP Stack, has crossed $10 billion in total value locked — entering the top three DeFi networks by TVL alongside Ethereum mainnet and Arbitrum. The milestone reflects rapid protocol deployment, growing stablecoin liquidity, and Coinbase's retail distribution advantage.

Base, Coinbase's Layer 2 network, has crossed $10 billion in total value locked — a milestone that places it in the top tier of DeFi networks by TVL, alongside Ethereum mainnet and Arbitrum. The growth has been rapid: Base crossed $1B TVL in late 2023, $5B in mid-2025, and reached the $10B milestone in May 2026, representing the fastest TVL growth trajectory of any Layer 2 network to date.
Base is built on the OP Stack — the same open-source codebase that powers Optimism — and benefits from Coinbase's extensive retail user base, brand recognition, and native integration in the Coinbase wallet and exchange.
Arbitrum remains the largest Layer 2 network by TVL, holding approximately $14–16 billion across its Arbitrum One and Arbitrum Nova chains. Arbitrum has a longer track record, a larger ecosystem of native protocols (GMX, Radiant, Camelot), and dominates perpetual trading volume among L2 networks.
Base's $10B TVL closing the gap with Arbitrum is notable because Base only launched its public mainnet in August 2023 — roughly three years after Arbitrum One. The pace of TVL accumulation suggests that Coinbase's retail distribution advantage is a genuine structural moat in the L2 competition.
Optimism (the network that Base's OP Stack is based on) remains at approximately $6–7B TVL, having been overtaken by both Arbitrum and Base in scale despite being earlier to market.
Aerodrome Finance has emerged as the defining native protocol on Base, offering concentrated liquidity pools, ve(3,3) tokenomics, and active liquidity incentive programmes that have attracted both retail LPs and protocol treasuries. Its AERO token has become the primary governance and incentive mechanism for Base DeFi.
Morpho, the modular lending protocol, has established a significant Base presence — particularly for USDC and cbETH (Coinbase's liquid staking token) lending markets. The combination of Morpho's capital efficiency and Base's low gas costs has made it a competitive venue for small and mid-size DeFi borrowing.
Uniswap V3 and V4 are both deployed on Base, with substantial USDC/ETH and USDC/USDT liquidity. Curve's crvUSD has also been deployed on Base, extending Curve's lending market beyond Ethereum mainnet for the first time.

Events like this affect the broader DeFi ecosystem by influencing market sentiment, regulatory expectations, protocol adoption, and on-chain activity. Understanding the context helps investors and users make more informed decisions about their exposure to decentralised finance protocols.
Significant DeFi developments — whether protocol upgrades, regulatory actions, or market milestones — can shift capital flows, yield opportunities, and risk profiles across the ecosystem. Staying informed through credible sources is essential for risk management in DeFi.
Our Base L2 research section covers protocols, ecosystems, and market developments in depth. Visit the relevant protocol or ecosystem page on this site for background context, or browse the DeFi Glossary for plain-English definitions of key terms.
Our editorial team verifies key claims against on-chain data, official announcements, and multiple primary sources before publication. We publish corrections promptly when new information changes our understanding.
Ethereum's Layer-2 ecosystem has become one of the most competitive arenas in crypto. Arbitrum, Base, and Optimism each hold distinct strategic positions — and the battle between them is reshaping where DeFi activity happens.
On 22 August 2026 Stani Kulechov said Aave deposits crossed $30 billion. That is a protocol deposit print, not DeFiLlama TVL, and it sits below 2025 peaks. Treat it as a recovery datapoint, not a buy call.
AAVE token fell 16% and $6 billion fled the protocol after attackers used drained rsETH to borrow wrapped ether, leaving Aave assessing its bad debt exposure from one of DeFi's most damaging contagion events.
