If you wanted to trade Bitcoin on a decentralized exchange a couple of years ago, your options were limited and the experience was, charitably, rough. Now Aerodrome Finance has quietly turned Coinbase’s Base network into the preferred venue for onchain Bitcoin spot trading, commanding somewhere between 50% and 65% of Base’s entire DEX market share.
That’s not a typo. A single protocol is handling more than half of all decentralized trading volume on one of the fastest-growing Layer 2 networks in crypto. And its grip has been tightening since January.
How Aerodrome cornered the Bitcoin DEX market
The story starts with cbBTC, Coinbase’s wrapped version of Bitcoin on Base. When cbBTC launched, Aerodrome captured 78% of its initial trading volume.
That early dominance wasn’t an accident. Aerodrome launched on August 28, 2023, as a fork of Velodrome, the leading DEX on Optimism. But rather than simply copy-pasting the code and calling it a day, the team behind the protocol, Dromos Labs, built what they call a “MetaDEX” model. Here’s the thing: the model channels trading fees and protocol incentives directly to users through a vote-escrowed governance mechanism called veAERO.
In English: if you lock up AERO tokens, you get to vote on where liquidity incentives go, and you earn a cut of the fees generated by the pools you vote for. It’s a flywheel. More locked tokens means more directed liquidity, which means better prices for traders, which means more volume, which means more fees for voters.
The result is that Aerodrome consistently ranks as the top venue for both Bitcoin and Ethereum trading pools on Base. Daily trading volumes regularly hit tens of millions of dollars, with peaks climbing higher during periods of market volatility.
Why Base became the battlefield
Coinbase routes significant retail and institutional activity through Base. When the exchange launched cbBTC, it essentially created a native pipeline for Bitcoin liquidity to flow into Base’s DeFi ecosystem. Aerodrome positioned itself at the end of that pipeline, capturing the bulk of trading activity before competitors could establish meaningful footholds.
Competing DEXs on Base do exist, but none have managed to challenge Aerodrome’s position in a sustained way. The protocol’s Total Value Locked and revenue generation consistently outpace its nearest rivals.
The veAERO flywheel and why it works
The vote-escrow model, borrowed and refined from Curve Finance’s pioneering veCRV system, requires users to lock their AERO tokens for extended periods. In return, they gain voting power over liquidity incentive distribution and earn a proportional share of protocol fees. The longer you lock, the more influence you wield.
Alex Cutler, who leads Dromos Labs, has focused development efforts on liquidity prediction tools and infrastructure improvements that make the flywheel spin faster. The team has also signaled plans for multi-chain expansion, including a potential move to Ethereum’s mainnet.
What this means for investors
For traders, Aerodrome’s deep liquidity pools on Base mean tighter spreads and better execution on Bitcoin trades compared to thinner DEX venues.
For DeFi investors evaluating the AERO token itself, the protocol’s dominance is a double-edged consideration. On one hand, controlling 50% to 65% of a growing network’s trading volume is an enviable position. Revenue flows directly to veAERO holders, creating tangible yield backed by real trading activity rather than inflationary emissions. On the other hand, that dominance is heavily tied to Base’s continued growth and Coinbase’s strategic decisions around cbBTC.
Aerodrome processing tens of millions in daily Bitcoin volume on a single L2 network suggests that decentralized spot markets are becoming a legitimate alternative to centralized order books for a growing segment of traders who value self-custody and transparency.
