Sidechain Contracts
Aura Finance is expanding to become a cross-chain protocol. Deploying to chains beyond Ethereum, with the intent to deploy to wherever the balancer is deployed and emitting rewards. As part of this expansion, a new set of contracts had been deployed.

Convex Platform "Lite" Contracts
The convex platform contracts developed for the sidechain are ‘lite’ variations of those used on Ethereum. In practice this means that contracts have functionality changed or removed, multiple contracts are merged together or contracts are not utilised on the sidechain.
BaseRewardPool4626
BoosterOwnerLite
BoosterLite
PoolManagerLite
VoterProxyLite
BaseRewardPool4626
Simply wraps the BaseRewardPool with the new IERC4626 Vault standard functions.
See https://github.com/fei-protocol/ERC4626/blob/main/src/interfaces/IERC4626.sol#L58 This is not so much a vault as a Reward Pool, therefore asset:share ratio is always 1:1. To create most utility for this RewardPool, the "asset" has been made to be the crvLP token, as opposed to the cvxLP token. Therefore, users can easily deposit crvLP, and it will first go to the Booster and mint the cvxLP before performing the normal staking function.
