Adapters

In order to exchange some of a fund's assets for other assets, an adapter generally integrates with one or more "integratees," i.e., endpoints at which to interact with a defi protocol such as Uniswap, Compound, ParaSawp, etc.

AaveV2Adapter

Integrates with Aave v2 lending via aTokens.
Functions and considerations:
  • lend() - None
  • redeem() - None

AaveV3Adapter

Integrates with Aave v3 lending via aTokens.
Functions and considerations:
  • lend() - None
  • redeem() - None

AuraBalancerV2LpStakingAdapter

Integrates with Aura to stake and unstake Balancer Pool Tokens (BPTs), via wrapped Aura staking tokens.
Can be used for combining Balancer LP/swap and Aura staking actions.
Functions and considerations:
  • lendAndStake() - None
  • takeOrder() - Uses Balancer Vault's batchSwap(). Use for LPing with nested composable stable pools.
  • unstake() - None
  • unstakeAndRedeem() - None
Above action implementations are the same as BalancerV2LiquidityAdapter​

BalancerV2LiquidityAdapter

Integrates with Balancer v2 to swap, and to lend/redeem/stake/unstake Balancer Pool Tokens (BPTs).
Functions and considerations:
  • lend() - None
  • lendAndStake() - None
  • redeem() - None
  • takeOrder() - Uses Balancer Vault's batchSwap(). Use for LPing with nested composable stable pools.
  • unstake() - None
  • unstakeAndRedeem() - None

CompoundAdapter

Integrates with Compound Finance's v2 cTokens. Each cToken is its own integratee.
Functions and considerations:
  • lend() - fund receives cToken , which triggers the VaultProxy to start accumulating COMP based on the amount lent.
  • redeem() - None
  • claimRewards() - None
Note that COMP is also claimable natively on Compound on behalf of the fund (by any user).

CompoundV3Adapter

Integrates with Compound Finance's v3 cTokens. Each cToken is its own integratee.
Functions and considerations:
  • lend() - fund receives cToken , which triggers the VaultProxy to start accumulating the reward token, if provisioned by the pool for the lent asset
  • redeem() - None
  • claimRewards() - None
Note that COMP is also claimable natively on Compound on behalf of the fund (by any user).

ConvexCurveLpStakingAdapter

Integrates with ConvexCurveLpStakingWrapper deployments to facilitate the staking of Curve LP tokens to Convex Finance.
Also provides convenience functions to LP on Curve and then stake on Convex in the same action, i.e., lendAndStake() and lendAndRedeem(). These actions use the same logic for LP'ing as the CurveLiquidityAdapter and thus have the same requirements and considerations.
Functions and considerations:
  • claimRewards() - none
  • stake() - fund starts accruing $CVX, $CRV and pool rewards (if applicable) after action
  • unstake() - none
  • lendAndStake() - fund starts accruing $CVX, $CRV and pool rewards (if applicable) after action
  • unstakeAndRedeem() - redemption can be made for either an equal balance of underlying pool tokens (relative to pool proportions), or for a single asset in the pool
Claiming accrued rewards on behalf of any fund can also be accomplished outside of the adapter via the ConvexCurveLpStakingWrapper .

CurveExchangeAdapter

Integrates with Curve's universal interface for swapping between any assets in a given pool.
Functions and considerations:
  • takeOrder() : none

CurveLiquidityAdapter

Integrates with Curve pools that adhere to Curve's pool templates to allow liquidity provision-related actions, including staking to tokenized liquidity gauges (i.e., LiquidityGaugeV2 and later).
Functions and considerations:
  • claimRewards() - none
  • lend() - none
  • redeem() - redemption can be made for either an equal balance of underlying pool tokens (relative to pool proportions), or for a single asset in the pool
  • stake() - fund starts accruing $CRV and pool rewards (if applicable) after action
  • unstake() - none
  • lendAndStake() - fund starts accruing $CRV and pool rewards (if applicable) after action
  • unstakeAndRedeem() - redemption can be made for either an equal balance of underlying pool tokens (relative to pool proportions), or for a single asset in the pool
Claiming accrued rewards can also be accomplished outside of the adapter through two mechanisms:
  • $CRV - must be claimed either through a call from the VaultProxy or by an account nominated via a call from the VaultProxy . We register all of these as approved vault calls.
  • pool rewards - can be claimed by any party at any time on behalf of the VaultProxy
Note on sidechains/L2s: earned $CRV is not paid via a Minter , but rather via the pool rewards mechanism described above.

ERC4626Adapter

Integrates with any tokenized vault that implements the ERC4626 standard, unless there is some non-standard behavior (e.g., redemption queue, special rewards claiming, etc).
Functions and considerations:
  • lend() : calls ERC4626.deposit()
  • redeem(): calls ERC4626.redeem()
  • no further options for interacting are currently supported

IdleAdapter

Integrates with the Idle Finance's IdleToken contracts using the functions available in V4 of its protocol.
Functions and considerations:
  • approveAssets() - can only be used for rewards tokens that are assets in the Enzyme asset universe
  • claimRewards() - claimed rewards tokens are sent to the Vault, but are not reported as incomingAssets, and thus are not emitted in an event, not run through policy management, and are not added as tracked assets
  • lend() - none
  • redeem() - any call to redeem() will also claim all rewards tokens; these rewards tokens are sent to the vault, but are not reported as incomingAssets, and thus are not emitted in an event, not run through policy management, and are not added as tracked assets
Unclaimed rewards transfer to the recipient during ERC20 transfer calls, rather than auto-checkpointing as other protocols do.

OneInchV5Adapter

Integrates with 1Inch (v5) swaps.
Functions and considerations:
  • takeMultipleOrders() - None
  • takeOrder() - None

ParaSwapV5Adapter

Integrates with ParaSwap (v5) via the AugustusSwapper. Incorporates asset approvals via the TokenTransferProxy.
Functions and considerations:
  • takeMultipleOrders() - None
  • takeOrder() - None

UniswapV2ExchangeAdapter

Integrates with UniswapV2 for trading.
Functions and considerations:
  • takeOrder() - None

UniswapV2LiquidityAdapter

Integrates with UniswapV2 for liquidity provision and redemption.
Functions and considerations:
  • lend() - None
  • redeem() - None

UniswapV3Adapter

Integrates with UniswapV3 for trading (not LP)
Functions and considerations:
  • takeOrder() - None

YearnVaultV2Adapter

Integrates with Yearn vault v2 instances
Functions and considerations:
  • lend() - none
  • redeem() - none
Note that while all Yearn vault v2 instances adhere to the same interface, each individual instance uses one of many particular versioned implementations (see v2.registry.ychad.eth). Only the adapter interactions with expected behaviors of interface functions can be realistically audited.

ZeroExV4Adapter

Integrates with the 0x Protocol v4.
This adapter limits orders to a list of makers, defined on the adapter. There can be multiple deployments of this adapter to facilitate different lists of allowed makers (or any maker).
Functions and considerations:
  • takeOrder() - none
Fee formulas - Previous
Performance Fee
Next - External Interactions
External Positions
