What Is Aerodrome Finance (AERO)? How It Works, Uses and Risks
What is Aerodrome Finance? Learn how the AERO DEX on Base works, how veAERO voting directs emissions and fees, the inflation and smart contract risks.
Aerodrome Finance (AERO) is a decentralized exchange and liquidity hub on Base, Coinbase's Ethereum layer-2 network, where AERO tokens are emitted to liquidity providers and holders who lock AERO as veAERO vote on which pools receive those emissions in exchange for the trading fees and incentives those pools generate. It launched in 2023 and is built by the team behind Velodrome on Optimism.
Aerodrome is a good example of "vote-escrow" tokenomics in action. Understanding it helps you judge not only AERO but many DeFi tokens with similar designs. This guide explains how the system works, what the token does, the risks and how to avoid fake AERO tokens.
Where Aerodrome Came From
Aerodrome launched on Base in August 2023, shortly after Base itself went live. Its design is adapted from Velodrome, a DEX on Optimism built by the same team, which in turn drew on the ve(3,3) model first popularized elsewhere in DeFi.
The goal was to become the central liquidity layer for Base: the place where new tokens find trading pairs and where projects compete for liquidity by rewarding voters.
How Aerodrome Works
The system has three groups of participants, and each one gets something different.
Liquidity providers
Users deposit token pairs into pools so traders can swap between them. Liquidity providers who stake their position earn AERO emissions instead of the trading fees. If you are new to providing liquidity, read liquidity pools explained first.
veAERO voters
AERO holders can lock their tokens for up to four years to receive veAERO, a voting position represented as an NFT. Longer locks give more voting power. Each week, voters choose which pools receive emissions. In return, they earn the trading fees from those pools and any incentives (sometimes called bribes) that projects deposit to attract votes.
Projects and protocols
A project that wants deep liquidity for its token can offer incentives to veAERO voters. If voters direct emissions to that pool, liquidity providers are drawn in by the AERO rewards. This turns liquidity into a market: projects pay voters, voters steer emissions and LPs follow the emissions. Our explainer on ve tokenomics covers the general model in depth.
Aerodrome also offers concentrated liquidity pools (branded Slipstream), where LPs choose a price range, similar to the idea described in our guide to concentrated liquidity.
What AERO Is Used For
| Use | How it works |
|---|---|
| Liquidity rewards | AERO is emitted weekly to staked liquidity providers |
| Governance and voting | Locked as veAERO, it directs emissions to pools |
| Fee and incentive income | veAERO voters receive fees and incentives from pools they back |
| Trading | AERO trades on Aerodrome and other venues |
Supply Design in Plain Words
AERO is inflationary: new tokens are created every week and paid to liquidity providers. The protocol's design adjusts emissions over time and includes a mechanism that distributes some new supply to veAERO lockers to reduce their dilution.
That means AERO holders who do not lock are diluted as new tokens enter circulation. Whether that dilution is offset depends on demand for veAERO, which depends on fees and incentives flowing through the platform. Check the latest emission parameters in Aerodrome's official documentation, and see live supply and price on the Aerodrome Finance price page.
Risks and Criticisms
- Smart contract risk: Aerodrome's pools and voting contracts hold user funds. Bugs or exploits could cause losses, even with audits.
- Dilution: ongoing emissions put selling pressure on AERO if rewards are dumped rather than locked.
- Lock-up risk: veAERO can stay locked for years. You cannot sell if conditions change, although locked positions can sometimes be traded as NFTs at a discount.
- Reflexivity: the system works well when fees and incentives are high. If activity on Base falls, rewards fall, which can weaken demand for AERO.
- Chain dependence: Aerodrome depends on Base, which relies on a sequencer operated by Coinbase. Outages or changes to Base affect the DEX.
- Impermanent loss for LPs: providing liquidity can leave you with less value than simply holding the tokens.
- Volatility: DeFi tokens can fall sharply in market downturns.

How to Find the Official AERO Token
AERO is a token on Base, so it has a contract address. Fake tokens with the same name and logo are common on Base DEXs.
- 1Find the official contract address in Aerodrome's documentation, reached by typing the domain yourself.
- 2Cross-check it with the AERO coin page on a trusted data site.
- 3Make sure your wallet is connected to Base, not another network.
- 4Only connect your wallet to the official Aerodrome app; fake DEX front ends are a common phishing route.
Our guide on how to check a token's contract address walks through each check.
Bottom line
Aerodrome turns liquidity on Base into a marketplace: projects pay veAERO voters, voters steer AERO emissions and liquidity providers follow the rewards. AERO's value depends on that flywheel staying busy, while emissions dilute holders who don't lock. Understand the lock terms, the smart contract risk and the inflation before you buy, and never risk more than you can afford to lose.
Frequently asked questions
What blockchain is Aerodrome on?
Aerodrome Finance runs on Base, the Ethereum layer-2 network incubated by Coinbase and built with the OP Stack. AERO is a token on Base, and you pay transaction fees on Base in ETH. Tokens claiming to be AERO on other chains should be verified carefully before you trust them.
What is veAERO?
veAERO is what you receive when you lock AERO for a chosen period, up to four years. It gives voting power that directs AERO emissions to liquidity pools, and voters earn the trading fees and incentives from the pools they vote for. Locked AERO cannot be withdrawn until the lock ends.
Is Aerodrome related to Velodrome?
Yes. Aerodrome was launched in 2023 by the team behind Velodrome, a similar DEX on Optimism. Both use a vote-escrow design in which locked-token holders direct emissions and earn fees, adapted from earlier ve(3,3) ideas in DeFi.
Does AERO have a fixed supply?
No. New AERO is emitted every week to reward liquidity providers, so supply grows over time. Emission rates and their adjustment are part of the protocol's design and governance, so check Aerodrome's official documentation and the live coin page for current figures.
