TL;DR
Base holds several billion dollars in DeFi TVL, anchored by Aerodrome, the largest DEX on the network.
Three uses cover most of the activity: spot trading and liquidity, lending, and stablecoin payments.
USDC is the working currency of Base DeFi. Most deep liquidity is priced in it, so you want native USDC when you arrive.
Across bridges into Base from 23+ chains in about 2 seconds and delivers native USDC through Circle's CCTP V2 for transfers up to $10 million.
Base grew a DeFi economy without renting it. There was no Base token to farm and no points program inflating the early numbers. Capital arrived because Coinbase's distribution funneled users in and the apps were worth using. By 2026 that economy holds several billion dollars in total value locked, sorted into a few categories worth knowing before you bridge in.
Aerodrome Is the Center of Gravity
Aerodrome is the largest DEX on Base and holds the biggest share of its TVL. It runs a ve(3,3) model: liquidity providers earn AERO emissions, and holders who lock AERO for voting power decide which pools those emissions flow to. That concentrates the deepest liquidity on Base in one place, which is why other apps route swaps through Aerodrome and most stablecoin pairs settle against its pools.
Trade, LP, or loop a position on Base and you are almost certainly touching Aerodrome, directly or through a router that does.
Three Things People Actually Do on Base
Spot trading and liquidity provision is the largest category by volume, dominated by Aerodrome and the venues that route through it. Bridged USDC usually lands here first.
Lending is the second pillar. Aave runs on Base, and its GHO stablecoin lets borrowers mint a native dollar against collateral instead of selling it. This is where idle bridged capital earns yield rather than sitting still.
Stablecoin payments are a deliberate bet for Base in 2026. The network has said its year is about onchain markets, stablecoin-based payments, and developers, with planned upgrades for stablecoin transaction fees and broader stablecoin liquidity. USDC sits underneath all of it, which decides how you should bridge: you want the canonical token on the other side, not a wrapped substitute.
USDC Is the Working Currency
Across all three categories, USDC is the unit that moves. Aerodrome's deepest pools quote it, Aave's markets price against it, payments settle in it. Bridge to Base to use the ecosystem rather than to park ETH, and USDC is the asset you want to arrive holding.
That puts weight on the bridge mechanism. A wrapped or bridged-IOU version of USDC sits in a separate pool from native USDC and can trade at a discount when the bridge is stressed. Native USDC carries no such gap; it is the same canonical token Circle issues on every chain.
Getting In: Bridge to Base with Across
Across moves assets to Base from 23+ chains with sub-2-second fills on mainnet. Pick your origin chain and token at the Base bridge route, choose what you want on Base, and confirm one transaction. Relayers deliver your funds on Base right away and reconcile later, so you never wait on finality.
For USDC, Across delivers the native token on Base. Smaller amounts fill through the relayer network in seconds; larger transfers route through Circle's CCTP V2, which burns USDC on the origin chain and mints fresh native USDC on Base for single transfers up to $10 million. The USDC that lands is the canonical token Aerodrome and Aave actually use.
And it has cleared billions since 2021 with no protocol-level exploit, so the capital you bridge in to chase Base yield isn't the risky part of the trip.
Base bet that good apps plus real distribution beats mercenary liquidity. The apps are here and the liquidity followed. The only thing left between you and using it is the way in.
