Aero launches October 21, 2026, with seven chains including Arbitrum

Aero: Aero is the unified liquidity layer for Ethereum, designed as a single exchange to power onchain finance by connecting liquidity across networks. It enables token swaps via Metaswaps, liquidity provision through Slipstream pools with dynamic fees and MEV capture, and permissionless market creation. Aero is set to launch on October 21, 2026, following the merger of Aerodrome and Velodrome, with full deployments across seven chains including new additions Robinhood Chain and Arbitrum. sAERO: sAERO represents staked or locked AERO tokens that grant holders the ability to direct AERO Rewards across the liquidity network using Predictive Allocation. At Aero's launch, sAERO holders will earn a share of exchange revenue from an expanding set of chains and pools. Arbitrum: Arbitrum is a leading Layer 2 scaling solution for Ethereum known for its deep DeFi ecosystem and high-volume onchain activity. It is one of the seven day-one chains for Aero's launch, providing expanded reach for the liquidity network and enabling sAERO holders to direct rewards across its established markets. Aerodrome: Aerodrome is a decentralized exchange protocol on Base that was part of the announced merger forming Aero. Its community and infrastructure have contributed to the development of Aero's features such as Predictive Allocation and the AER Engine ahead of the October 2026 launch. Velodrome: Velodrome is a decentralized exchange protocol on Optimism that merged with Aerodrome to create Aero. It has supported the integration of new primitives like Dynamic Fees and MEV Capture, with its users now aligned behind Aero's single token and cross-chain liquidity system. AER Engine: The AER Engine is the core optimization system for Aero's token economy, calculating rewards in dollar value and dynamically managing rates per pool to align with projected revenue. It supports the launch by enabling efficient incentive distribution across all seven chains while controlling inflation for liquidity providers. Robinhood Chain: Robinhood Chain is a blockchain ecosystem focused on expanding access to onchain finance and bringing new participants into decentralized trading. It joins Aero's launch network to integrate with the unified liquidity layer, allowing seamless cross-chain swaps and liquidity incentives for its growing community of users. Launch Timeline: Aero is scheduled to go live on October 21, 2026, with full deployments on seven EVM chains. Merger Background: Aerodrome and Velodrome completed their merger to form Aero, adding features such as Predictive Allocation and completing public audits in the lead-up to launch. Cross-Chain Expansion: The addition of Robinhood Chain and Arbitrum expands Aero's reach into new ecosystems alongside Base, Ethereum Mainnet, OP Mainnet, Arc, and Ink.
