What is the biggest DEX on Base?

Aerodrome. Measured across the busiest pools on Base, Aerodrome Slipstream and its pool variants carry roughly 45% of 24-hour DEX volume, ahead of Uniswap V4 at 25% and Uniswap V3 at 14%. Most guides assume Uniswap leads on Base; by traded volume it does not.

Do I need a different wallet to trade on Base?

No. Base is an EVM chain with id 8453, so any Ethereum wallet works. The gas token is ETH, and the wrapped version is WETH at 0x4200000000000000000000000000000000000006.

How much does a swap cost on Base?

Gas is very cheap. A representative WETH to USDC swap quoted roughly $0.013 in gas. That is low enough that small trades are practical, unlike chains where gas dominates the trade.

Is it better to use an aggregator on Base?

Usually yes. Base liquidity is split across Aerodrome, Uniswap V3 and V4, and PancakeSwap, and much of the real flow arrives through aggregators rather than any single router. An aggregator prices all of them at once and splits the route where that pays.

Can I trade Base on Schwep?

Not yet. Schwep trades Robinhood Chain today. Base market data and the routing integration are built; trading turns on once the routing contract is deployed to Base.

How to trade on Base

Most guides tell you to use Uniswap. On Base that is the second-biggest venue. Here is what the volume actually says, measured rather than assumed.

Every DEX on Base, ranked by real 24-hour volume

This is not a directory listing. We took the busiest pools on Base and tallied where the 24-hour volume actually sat.

Venue	Share of volume	What it is
Aerodrome Slipstream (3 pools variants)	~45%	Concentrated liquidity, Velodrome lineage
Uniswap V4	25.0%	Singleton PoolManager
PancakeSwap V3	14.7%	Uniswap V3 fork
Uniswap V3	14.1%	Router `0x2626664c…e481`
Hydrex Integral	0.6%	—
Uniswap V2	0.2%	Constant product

Aerodrome is the market on Base. Its Slipstream pools plus the other Aerodrome variants come to roughly 45% of volume. Uniswap V4 and V3 together are about 39%. If your mental model of Base is “it’s a Uniswap chain”, your routing is starting from the wrong place.

The thing nobody mentions: Aerodrome has no router to point at

We probed the fifteen busiest contracts calling swap() on Aerodrome pools. Not one of them exposes a standard router interface — no factory(), no WETH9(). Aerodrome’s flow arrives through aggregators, not through a single public SwapRouter the way Uniswap’s does.

The practical consequence for you: on Base, an aggregator is not a convenience, it is how the biggest venue is reached in the first place.

What a swap actually costs

Gas is the good news

A representative 1 WETH → USDC quote came back at about $0.013 of gas. Base is cheap enough that trade size is not constrained by gas, which is not true everywhere — the same quote on HyperEVM cost roughly 580× more. That comparison is here.

Before you trade anything on Base

1. Check who holds the supply, not just the top ten

“Top 10 wallets hold 0%” sounds perfect and usually means nobody holds the token at all — the supply is still sitting in the pool contract. On a sample of fresh launches we measured, seven in eight would have shown a reassuring 0% for exactly that reason. Ask what share of supply is in wallets at all before you read a concentration number.

2. Check the deployer’s history

A creator who has launched dozens of tokens in a week is running a production line. That is knowable before you buy and it is the single cheapest check available.

3. Simulate the sell, not just the buy

Plenty of tokens are easy to buy and hard to sell. A round-trip simulation prices the exit before you take the entry.

Where Schwep fits

Straight answer: Schwep does not trade Base yet. It trades Robinhood Chain today. The Base integration — market data, the venue map above, and routing through an aggregator so Aerodrome is reachable — is built and tested. Trading switches on when the routing contract is deployed to Base. If you want it the day it lands, the terminal is here.
