Convex 3Crv Vaults
ERC-4626 vaults that deposits Curve 3Pool LP tokens (3Crv) in a Curve 3Pool-based Metapool, eg musd3Crv; deposits the Metapool LP token in a Convex pool; and stakes the Convex LP token, eg cvxmusd3Crv, for CRV and CVX rewards.
The Convex rewards are swapped for a Curve 3Pool token, eg DAI, USDC or USDT, using the
Liquidatormodule and donated back to the vault. On donation back to the vault, the DAI, USDC or USDT is deposited into the underlying Curve Metapool; the Curve Metapool LP token is deposited into the corresponding Convex pool and the Convex LP token staked.
- Invests 3Crv assets in a Curve Metapool and LP token staked in Convex for boosted returns.
- Sandwich attack protection on ERC4626 operations
- Liquidation of Convex rewards like CRV and CVX for more reinvested 3Crv assets.
- Front-running protection against liquidation of rewards by streaming the increase in assets per share.
- Fee charged on liquidated Convex rewards.
- Vault operations are pausable by the
- Emergency asset recovery by the
Governor. This will be removed after 2 months.
- Vault configuration is controlled by a protocol
Governor. This includes:
- Setting the slippage limits for mint, deposit, redeem and withdraw.
- Setting the account that receives the liquidation fee.
- Initially the
Governorcan upgrade the contracts via a proxy without a time delay. After 6 weeks, this will be changed to a one week time delay.
3CRV token scale
Curve.fi pool the 3Crv asset is deposited into. eg musd3CRV, MIM-3LP3CRV-f or usdp3CRV.
Curve.fi Metapool liquidity provider token. eg Curve.fi MUSD/3Crv (musd3CRV)
Scale of the metapool liquidity provider token. eg 1e18 if 18 decimal places.
Curve's 3Pool used as a base pool by the Curve metapools.
contract IConvexBooster booster
Convex's Booster contract that contains the Curve.fi LP pools.
Convex's pool identifier. eg 14 for the musd3CRV pool.
contract IConvexRewardsPool baseRewardPool
Convex's base rewards contract for staking Convex's LP token. eg staking cvxmusd3CRV

Governor liquidates all the vault's assets and send to the governor. Only to be used in an emergency. eg whitehat protection against a hack.
Minimum amount of asset tokens to receive from removing liquidity from the Curve 3Pool. This provides sandwich attack protection.
