Protocol

All contracts for the Protocol, an AMM on EVMs.

Protocol Overview

AMM contracts

Filename	Description
Pool.sol	AMM constant-product implementation similar to Uniswap V2 liquidity pools
Router.sol	Handles multi-pool swaps, deposit/withdrawal, similar to Uniswap V2 Router interface
PoolFees.sol	Stores the liquidity pool trading fees, these are kept separate from the reserves
ProtocolLibrary.sol	Provides router-related helpers, eg. for price-impact calculations
FactoryRegistry.sol	Registry of factories approved for creation of pools, gauges, bribes and managed rewards.

Tokenomy contracts

Filename	Description
Moni.sol	Protocol ERC20 token
VotingEscrow.sol	Protocol ERC-721 (ve)NFT representing the protocol vote-escrow lock. Beyond standard ve-type functions, there is also the ability to merge, split and create managed nfts.
Minter.sol	Protocol token minter. Distributes emissions to Voter.sol and rebases to RewardsDistributor.sol.
RewardsDistributor.sol	Is used to handle the rebases distribution for (ve)NFTs/lockers.
VeArtProxy.sol	(ve)NFT art proxy contract, exists for upgradability purposes
AirdropDistributor.sol	Distributes permanently locked (ve)NFTs to the provided addresses, in the desired amounts.

Protocol mechanics contracts

Filename	Description
Voter.sol	Handles votes for the current epoch, gauge and voting reward creation as well as emission distribution to Gauge.sol contracts.
Gauge.sol	Gauges are attached to a Pool and based on the (ve)NFT votes it receives, it distributes proportional emissions in the form of protocol tokens. Deposits to the gauge take the form of LP tokens for the Pool. In exchange for receiving protocol emissions, claims on fees from the pool are relinquished to the gauge. Standard rewards contract.
rewards/
Reward.sol	Base reward contract to be inherited for distribution of rewards to stakers.
VotingReward.sol	Rewards contracts used by FeesVotingReward.sol and BribeVotingReward.sol which inherits Reward.sol. Rewards are distributed in the following epoch proportionally based on the last checkpoint created by the user, and are earned through "voting" for a pool or gauge.
FeesVotingReward.sol	Stores LP fees (from the gauge via PoolFees.sol) to be distributed for the current voting epoch to it's voters.
BribeVotingReward.sol	Stores the users/externally provided rewards for the current voting epoch to it's voters. These are deposited externally every week.
ManagedReward.sol	Staking implementation for managed veNFTs used by LockedManagedReward.sol and FreeManagedReward.sol which inherits Reward.sol. Rewards can be earned passively by veNFTs who delegate their voting power to a "managed" veNFT.
LockedManagedReward.sol	Handles "locked" rewards (i.e. Aero rewards / rebases that are compounded) for managed NFTs. Rewards are not distributed and only returned to VotingEscrow.sol when the user withdraws from the managed NFT.
FreeManagedReward.sol	Handles "free" (i.e. unlocked) rewards for managed NFTs. Any rewards earned by a managed NFT that a manager passes on will be distributed to the users that deposited into the managed NFT.

Governance contracts

Filename	Description
ProtocolGovernor.sol	OpenZeppelin's Governor contracts used in protocol-wide access control to whitelist tokens for trade within the protocol, update minting emissions, and create managed veNFTs.
EpochGovernor.sol	A simple epoch-based governance contract used exclusively for adjusting emissions.
