Aerodrome

Aerodrome operates as a decentralized exchange and liquidity platform launched in 2023 on Base, Coinbase's EVM-compatible Layer 2 built atop the Optimism OP Stack. It delivers an automated market maker (AMM) framework for token exchanges on Base, supporting volatile AMM (vAMM) pools suited to uncorrelated pairs and stable AMM (sAMM) pools designed for correlated or pegged assets. The service is available via aerodrome.finance, with contract code open-sourced on GitHub at github.com/aerodrome-finance and security details hosted at aerodrome.finance/security.

AERO serves as the native emissions and governance token within Aerodrome's ve(3,3) tokenomics, allowing users to direct liquidity incentives across Base pools. The liquidity marketplace enables protocols and providers to engage via an incentive layer where protocols steer AERO emissions to their pairs through veAERO votes, and providers capture fees plus emissions from high-vote pools. Protocol architecture, pool mechanics, and integration guides are documented in the GitHub repository at github.com/aerodrome-finance/docs.

Users begin at aerodrome.finance by linking an EVM wallet to perform token swaps on Base via the AMM pools. The system routes trades through vAMM pools for volatile pairs employing the constant product formula (x * y = k) or sAMM pools for stable pairs using a StableSwap-style invariant to minimize slippage on near-equal trades. The interface shows estimated output, price impact, and slippage settings prior to on-chain confirmation.

Liquidity providers choose a pair, deposit tokens in the required ratio for the pool type, and receive LP tokens proportional to their share. Trading fees from swaps accrue to LP holders based on their position size. The marketplace layer supplies an extra rewards stream: pools attracting veAERO votes receive AERO emissions distributed to their LPs each epoch, tying deeper liquidity to governance-directed vote allocation.

Aerodrome structures its AMM pools into two categories according to token price dynamics. Volatile AMM (vAMM) pools follow the constant product formula (x * y = k) akin to Uniswap v2, pricing swaps along a hyperbolic curve that preserves constant token balance products. Stable AMM (sAMM) pools apply a StableSwap-style invariant optimized for correlated or pegged pairs such as stablecoins or liquid staking tokens, minimizing slippage on large trades relative to pool depth. Pool creators choose the type at launch based on the tokens' price correlation.

The AERO token powers the ve(3,3) incentive system where holders lock tokens for vote-escrowed veAERO to gain voting power over weekly emissions. veAERO participants vote each epoch to allocate emissions across pools proportionally to received vote weight. Liquidity providers in voted pools earn swap fees plus the allocated AERO emissions, directly connecting provider yields to governance activity via the veAERO mechanism.

Protocols can deposit bribe tokens into a pool's reward contract to compensate veAERO voters who allocate votes to it. Voters supporting bribed pools receive a share of the bribe tokens for that epoch alongside fee revenue from supported pools. This establishes a competitive marketplace for liquidity direction where protocols bid for votes through bribes, and voters assess options based on combined fee income, bribe rewards, and liquidity strategy.

Smart contract code is publicly available on GitHub at github.com/aerodrome-finance, offering access to pool factories, routers, gauges, bribes, and ve(3,3) governance infrastructure. Base developers can integrate swap routing, pool queries, and liquidity tools using the published ABIs and docs in the GitHub repository at github.com/aerodrome-finance/docs. Security references including audits are available at aerodrome.finance/security for teams assessing contract posture ahead of integrations or liquidity provision.

Aerodrome enables token swaps, liquidity provision, and incentive distribution on Base: traders exchange ERC-20 tokens via the aerodrome.finance interface with vAMM or sAMM routing matched to pair characteristics; liquidity providers deposit pairs into pools to collect swap fees; Base protocols attract liquidity by posting bribes to draw veAERO votes and emissions; AERO holders lock for veAERO to direct emissions, earn fees from voted pools, and capture bribe rewards; developers integrate swap routing and pool interfaces using contracts and documentation at github.com/aerodrome-finance.

Aerodrome's ve(3,3) implementation on Base merges vote-escrowed locking with cooperative incentives to align emissions with liquidity needs. AERO holders lock tokens for veAERO, where longer lock periods grant greater voting power. Each epoch, veAERO holders vote to distribute that epoch's AERO emissions across pools, with emissions flowing to LP positions proportional to the pool's vote share. The (3,3) element promotes a cooperative outcome: voters maximize returns by backing high-bribe or high-fee pools, while LPs concentrate in heavily voted pools, fostering alignment between governance and efficient liquidity on Base.

Security documentation is maintained at aerodrome.finance/security, supplying users and developers with the protocol's audit and review history on Base. Contract source code for the AMM factory, router, gauge, bribe, and governance elements is open at github.com/aerodrome-finance for independent review before liquidity provision or integrations. As a non-custodial AMM, Aerodrome never holds user funds centrally—swaps, deposits, withdrawals, and locking occur via on-chain contracts with all changes verifiable on Base. Users should consult the security docs at aerodrome.finance/security and follow standard Web3 wallet practices before connecting or transacting.

Aerodrome delivers a Base-native decentralized exchange and liquidity marketplace via dual AMM architecture—vAMM pools using the constant product formula (x * y = k) for volatile pairs and sAMM pools with StableSwap-style invariants for correlated assets—paired with a ve(3,3) model that directs AERO emissions through veAERO voting, epoch fees, and protocol bribe markets. Security references at aerodrome.finance/security, open contracts at github.com/aerodrome-finance, and documentation at github.com/aerodrome-finance/docs equip developers, providers, and protocols with resources to assess the AMM design and security on Base. Evaluators should review the documentation, contract repositories, and security materials at aerodrome.finance/security to understand pool selection, ve(3,3) mechanics, and wallet requirements before trading or supplying liquidity.
