Aero is a cross-chain spot exchange from Dromos Labs that merges Aerodrome and Velodrome into a single liquidity network running on blockchains like Base and Ethereum. Liquidity providers earn AERO rewards denominated in dollars and capped against each pool's projected revenue, while AERO holders who stake as sAERO direct those rewards across markets and receive 100% of pool-level exchange revenue.
Aero is the successor to Aerodrome Finance and Velodrome Finance, two vote-escrow AMMs built by the team behind Dromos Labs, led by CEO Alexander Cutler. Velodrome launched on OP Mainnet in 2022, and Aerodrome followed on Base in August 2023 as a fork of Velodrome V2, becoming the largest DEX on Base by trading volume. In November 2025, Dromos Labs announced that the two exchanges would merge into a single protocol, Aero, built on its MetaDEX03 architecture, with one token and one liquidity network across multiple EVM chains.
Aero replaces the weekly ve(3,3) epoch with Predictive Allocation, a continuous system in which sAERO holders direct AERO rewards to markets and earn a share of the revenue those markets generate while their allocation is live. Rewards are priced in dollars and capped as a multiple of each pool's projected revenue, and capped rewards are never minted. The launch also introduced Metaswaps for single-transaction cross-chain swaps and Slipstream V3, a concentrated-liquidity AMM with dynamic fees and MEV recapture on supported L2s. The entire upgraded AERO supply went to existing AERO and VELO holders, split 94.5% to the Aerodrome community and 5.5% to the Velodrome community based on each protocol's share of combined revenue over the prior 52 weeks, with no venture or token-sale allocation. Contracts were audited by Sherlock and ChainSecurity across five engagements, followed by a public audit contest on Sherlock.
