Aero Widens Aerodrome's Market but Not Its Economics

The Base-native decentralized exchange (DEX) – a venue that lets users trade directly onchain without an intermediary – is set to unify with Velodrome, its sister protocol on Optimism, under a new structure called Aero. The move turns two separate liquidity venues into one broader exchange layer, with a single token, one governance and economic framework, and a cross-chain architecture designed to route liquidity across more of the Ethereum ecosystem.

Aerodrome remains one of Base's most important trading venues, but its standalone fundamentals are no longer as strong as they were at prior peaks. The unification gives it a larger addressable market and a cleaner strategic story. The question is whether Aero can convert that into higher-quality activity, rather than simply adding more subsidized volume.

Why Aerodrome, Velodrome are unifying

Aerodrome and Velodrome are sister decentralized exchanges built around vote-directed liquidity incentives, the ve(3,3) model Velodrome refined on Optimism. Aerodrome became the main liquidity venue on Base, Coinbase's Layer-2 network, while Velodrome played a similar role on Optimism and its connected Superchain.

That model worked well enough to make both protocols relevant in their ecosystems. But it also created fragmentation. Liquidity, governance, incentives and token value were split across separate venues. In a market where trading increasingly moves across chains, that separation becomes a constraint. A trader does not care whether the best route sits on Base, Optimism or another connected chain. They care about execution, depth, fees and reliability.

Aero is designed to solve that fragmentation, coordinating liquidity through one system rather than forcing users and liquidity providers to navigate multiple isolated exchanges. For Aerodrome specifically, the strategic benefit is clear: it can move from being a Base-native DEX to being the main hub of a wider Ethereum liquidity layer.

The unification also folds a broader set of upgrades into one Aerodrome-led system. A unified token and governance framework should make incentives easier to coordinate across chains, while cross-chain routing should widen the pool of potential trading activity beyond Base. Predictive Allocation, introduced as part of the transition, is designed to improve how emissions are directed by making rewards more responsive to where liquidity is actually needed. Slipstream V3, Metaswaps and mechanics resistant to maximal extractable value (MEV) are also part of the post-unification architecture, aimed at improving execution quality, expanding cross-chain access and protecting productive liquidity. In theory, these should make Aerodrome's liquidity more useful beyond Base – but only if the unified system attracts new routed volume rather than simply consolidating existing activity.

Big volume, weak economics

Aerodrome still has scale. For the week of 22 Jun, the protocol processed roughly $1.99bn in volume. On its own, nearly $2bn of weekly DEX volume remains meaningful. But the broader trend is softer. That same $1.99bn reading was about 24% below the four-week average, 30% below the 12-week average and 44% below the 52-week average. Aerodrome is still active, but compared with its own recent history, it is not accelerating.

Adding Velodrome's trading activity does not materially change the current run-rate. In the latest shared week, Velodrome added only $47.7mn of volume, taking the combined total to roughly $2.04bn. Aerodrome accounted for 97.7% of that. The same pattern holds over longer windows: Aerodrome represented about 98% of combined volume over the past four and 12 weeks, and 96.2% over the trailing year.

That makes the Aero story more asymmetric than a simple merger implies. Velodrome adds strategic reach into Optimism and the Superchain, but Aerodrome supplies nearly all the current trading base. In practice, Aero will begin with an Aerodrome-led volume profile. The unification may create a cleaner cross-chain liquidity network, but it should not be expected to mechanically add much trading scale from Velodrome's existing activity alone.

That matters because fees and earnings are already the weaker part of Aerodrome's profile. It generated about $699k in weekly fees in the week of 22 Jun, up 6.5% week on week but still 18% below the 12-week average and 72% below the 52-week average. The gap between volume and fees is the point. In the latest week, Aerodrome's fee take rate was roughly 3.5 basis points, below the 52-week average of about 7.1. Each dollar of volume is producing less fee revenue than it did across the trailing year. Earnings show the issue more starkly: Aerodrome's latest weekly earnings were negative $472k, better than the prior week's negative $647k, but still negative. Implied incentives were about $1.17mn, roughly 1.7 times the weekly fees. Aerodrome remains a major venue, but it continues to rely on incentives to support that activity.

The Velodrome unification does not solve that. Because Velodrome contributes only a small share of combined volume, it should not be expected to add much fee or earnings scale either. On its current volume share, Velodrome would need a far higher fee rate or a very different earnings profile to shift the combined economics from day one. That puts the weight on the organic part of the thesis. The important question is not whether reported volume rises once the two are viewed as one system – some increase may simply reflect consolidation. The question is whether Aero can create new routed volume through cross-chain execution, better liquidity coordination and improved incentive allocation.

Real test is fee conversion

Aero gives Aerodrome a larger market, but not a free pass. It enters the unification with real usage and meaningful scale, yet its latest fundamentals show weaker fee capture and negative earnings. Velodrome gives the unified protocol broader reach, but little current volume. The merger alone is unlikely to materially improve fees or earnings unless Aero generates genuinely new activity or makes existing volume more profitable.

The unification can plausibly increase Aerodrome's addressable market. The harder test is whether it can make that market economically useful. To validate the thesis, volume growth needs to come with stronger fee capture, lower incentive leakage and a clearer path toward positive earnings. Otherwise, the protocol ends up with a bigger liquidity network but the same underlying problem: large volumes that do not yet translate into strong enough economics.
