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

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).

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

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
