**Question:** How much trades on Aerodrome, which pools do votes reward and how much of its liquidity has moved to Aero?

- Kind: Dashboard in Voltfin Vantage
- Topic: [DeFi](https://voltfincrypto.com/topics/defi)
- Chains: Base
- Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is.

Aerodrome launched on Base in 2023 with the ve(3,3) model that Velodrome built on OP Mainnet. Liquidity providers who stake in a gauge earn AERO emissions instead of trading fees; holders who lock AERO as veAERO vote each week on which pools get those emissions, and in return collect the fees and incentives of the pools they vote for. Pools come in two kinds: basic stable and volatile pools, and Slipstream concentrated-liquidity pools.

In October 2026 Aerodrome and Velodrome merged into one exchange, Aero, which runs on Base, OP Mainnet, Ethereum and other chains. AERO and VELO convert into a new AERO token, and veAERO and veVELO positions convert into staked AERO. This dashboard keeps Aerodrome's history on Base and follows its pools through the change, labelling every pool by the factory that created it, so liquidity moving to Aero's contracts shows as a migration rather than a loss.

## Blueprint

### Pools

Aerodrome's and Aero's volume, fees and liquidity on Base.

- **Volume, latest day** (USD): Swap volume in every Aerodrome and Aero pool on Base on the latest complete day.
- **Fees, latest day** (USD): Trading fees paid on the latest complete day, whether they went to voters or to unstaked providers.
- **TVL** (USD): Tokens held in Aerodrome and Aero pools on Base at the latest day's last block, valued at oracle prices.
- **Liquidity in Aero pools** (%): The share of that liquidity held in pools created by Aero's factories, which rises as providers migrate.
- **Volume by pool type** (USD): Daily volume stacked by basic stable, basic volatile, Slipstream and Aero pools.
- **Largest pools**: Each pool's pair, type, factory, volume, fees, liquidity, staked share and votes in the latest epoch.

### Votes

Each epoch's votes, emissions and what voters earned.

- **AERO locked or staked** (AERO): AERO in veAERO locks and, since the merger, in Aero staking at the latest epoch start.
- **Voter rewards, last epoch** (USD): Fees and incentives paid to voters for the last complete epoch, across every pool.
- **Votes by pool** (%): The share of the latest epoch's votes each pool received, with small pools grouped.
- **Emissions and voter rewards** (USD): The value of each epoch's emissions beside the fees and incentives voters earned in it.

Filters: Pool type (Basic stable, basic volatile, Slipstream, Aero or all); Period (Last 7, 30 or 90 days).

## How it will be measured

- Volume and fees come from the Swap events of every pool created by Aerodrome's basic pool factory and Slipstream factory on Base, and from Aero's factories as its pools go live, with each pool labelled by its factory.
- Swaps are valued at the stablecoin leg or an oracle price at the swap's block, and fees use the rate each pool charged at the time, including any dynamic fee.
- Votes, emissions and voter rewards are read per weekly epoch, which starts on Thursday at 00:00 UTC, from the Voter contract's vote events, each gauge's reward notices and the pools' fee and incentive reward contracts.
- Locked and staked AERO come from the voting escrow and Aero's staking contracts at each epoch start, and token conversions from the migration contracts' events.

## Data it needs

- `dex_swaps_daily` (to build): Swap counts and volume per DEX, pool and chain per day, decoded from Swap events, valued with stablecoin legs and oracle prices.
- `dex_liquidity_daily` (to build): Liquidity held by each DEX pool at day end, in tokens and valued in USD, with fee tier and pool age.
- `governance_votes` (to build): Proposals, votes, voting power and turnout in on-chain governors, with off-chain votes recorded with their source.
- `token_supply_daily` (to build): Total supply of each registry token on each chain at day end: wrapped BTC, liquid staking tokens, tokenized assets and other tracked tokens.
- `protocol_revenue_daily` (to build): Fees users paid to each protocol and the part kept by the protocol or its token holders, per protocol and day, including buybacks.
- `native_prices_daily` (to build): Reference prices of major assets read from on-chain oracle feeds (Chainlink latestRoundData) at each day's last block, with each round's update time.

- Source: Swap events of every pool, with Slipstream fee settings at the swap block
- Source: Voter contract vote events and gauge reward notices per epoch
- Source: Fee and incentive reward contracts of each pool
- Source: Voting escrow locks, Aero staking balances and migration contract events

## Questions

### What happened to Aerodrome?

In October 2026 Aerodrome merged with Velodrome into a single exchange called Aero, built by the same team. AERO converts into the new AERO token and veAERO positions into staked AERO. The dashboard keeps the Aerodrome record on Base and adds Aero's pools as they take over.

### How do Aerodrome votes and emissions work?

Each weekly epoch, veAERO holders vote for pools. The next epoch's emissions are split between gauges in proportion to those votes, and voters earn the fees and incentives of the pools they backed, which ties emissions to the pools that pay voters the most.

### Do Aerodrome liquidity providers earn trading fees?

Providers who stake in a pool's gauge earn AERO emissions, and that pool's trading fees go to the voters who directed emissions to it. Providers who leave their liquidity unstaked earn trading fees instead of emissions.

### What is Slipstream?

Aerodrome's concentrated-liquidity pools. Providers choose a price range, as on Uniswap v3, and staked liquidity earns emissions only while the price is inside that range, which rewards liquidity that is actually used.

### Is Aerodrome volume the same as Base DEX volume?

No. Aerodrome is one of several DEXs on Base. This page counts only pools created by Aerodrome's and Aero's factories, while the DEX volume by chain dashboard adds every exchange on Base together.

## Glossary

- **ve(3,3)**: A token model in which locked tokens vote on emissions and earn the fees and incentives of the pools they vote for.
- **Epoch**: One week of votes and emissions, starting on Thursday at 00:00 UTC.
- **Gauge**: The contract that holds a pool's staked liquidity and pays it emissions according to the votes the pool received.
- **Slipstream**: Aerodrome's concentrated-liquidity pools, where staked liquidity earns emissions while its range covers the current price.
