Base Hits $10 Billion TVL: Coinbase's Layer 2 Becomes a Top-3 DeFi Network

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.

What Is Driving Base's Growth

• Coinbase distribution: Coinbase's 100 million+ verified users have native access to Base through the Coinbase wallet, creating a retail onboarding funnel that no other L2 can match.
• USDC liquidity: As Circle's parent company, Coinbase has prioritised deep USDC liquidity on Base. Base is now the second-largest network by USDC on-chain supply, after Ethereum mainnet.
• Protocol deployment: Aave, Uniswap, Curve, Morpho, and Aerodrome (Base's dominant native DEX) are all active on Base, providing users with access to the core DeFi stack at low gas costs.
• Aerodrome Finance: Aerodrome, a ve(3,3) DEX built natively on Base, has attracted over $1.5B in TVL and has become the primary AMM and liquidity bootstrapping mechanism for new token launches on Base.
• Pectra blob expansion: The Pectra upgrade's increased blob capacity has directly reduced Base's data posting costs on Ethereum, lowering gas fees for Base users.

Base vs Arbitrum: The L2 Competition

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.

DeFi Activity on Base

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.
