Aave Earn Vault Management#

Manage your deployed vaults with fee configuration and revenue collection.

Set Vault Fee#

The fee for a vault has to be at least 10%.

Update the performance fee for your vault (vault owner only).

1

Identify the Vault#

First, identify the vault you want to update the fee for.

Let's say we have identified a vault that we own with the following details:

Owned Vault
const vault: Vault = {  __typename: "Vault",  address: "0x1234567890abcdef1234567890abcdef12345678",  owner: "0x742d35cc6e5c4ce3b69a2a8c7c8e5f7e9a0b1234", // Your address  shareName: "Aave USDC Vault Shares",  shareSymbol: "avUSDC",  chainId: 1,  usedReserve: {    __typename: "Reserve",    underlyingToken: {      __typename: "Currency",      symbol: "USDC",      name: "USD Coin",      address: "0xA0b86a33E6441c8c5f0bb9b7e5e1f8bbf5b78b5c",      // …    },    // …  },  fee: {    __typename: "PercentValue",    raw: "50000000000000000000000000",    decimals: 27,    value: "0.11",    formatted: "11", // 11% performance fee  },  totalFeeRevenue: {    __typename: "TokenAmount",    amount: {      __typename: "DecimalValue",      value: "1250.75", // Total fees collected      // …    },    // …  },  // …};
You must be the vault owner to update the fee.

2

Prepare the Transaction Request#

Next, create the transaction request for updating the vault fee.

Use the useVaultSetFee hook to create the transaction request for updating the vault fee.

Set Fee
import { useWalletClient } from "wagmi";import { useVaultSetFee, bigDecimal } from "@aave/react";
// …
const { data: walletClient } = useWalletClient();
const [setFee, settingFee] = useVaultSetFee();
const result = await setFee({  chainId: vault.chainId,  vault: vault.address,  newFee: bigDecimal(15), // 15% performance fee});
// …

3

Send the Transaction#

Finally, send the transaction.

Use the useSendTransaction hook for the wallet library of your choice to send the transaction.

Viem
import { useWalletClient } from "wagmi";import { useVaultSetFee } from "@aave/react";import { useSendTransaction } from "@aave/react/viem";
// …
const { data: walletClient } = useWalletClient();
const [setFee, settingFee] = useVaultSetFee();const [sendTransaction, sending] = useSendTransaction(walletClient);
const loading = settingFee.loading || sending.loading;const error = settingFee.error || sending.error;
// …
const result = await setFee({  // …}).andThen(sendTransaction);
if (result.isErr()) {  console.error("Set fee failed:", result.error);} else {  console.log("Set fee successful with hash:", result.value);}

Withdraw Fees#

Withdraw accumulated fees from your vault (vault owner only).

Withdrawn fees are received in the form of the underlying Reserve aTokens.

1

Identify the Vault#

First, identify the vault you want to withdraw fees from.

Let's say we have identified a vault that we own with accumulated fees:

Vault with Fees
const vault: Vault = {  __typename: "Vault",  address: "0x1234567890abcdef1234567890abcdef12345678",  owner: "0x742d35cc6e5c4ce3b69a2a8c7c8e5f7e9a0b1234", // Your address  shareName: "Aave USDC Vault Shares",  shareSymbol: "avUSDC",  chainId: 1,  usedReserve: {    __typename: "Reserve",    underlyingToken: {      __typename: "Currency",      symbol: "USDC",      name: "USD Coin",      address: "0xA0b86a33E6441c8c5f0bb9b7e5e1f8bbf5b78b5c",      // …    },    // …  },  fee: {    __typename: "PercentValue",    raw: "150000000000000000000000000",    decimals: 27,    value: "0.15",    formatted: "15", // 15% performance fee  },  totalFeeRevenue: {    __typename: "TokenAmount",    amount: {      __typename: "DecimalValue",      value: "1250.75", // Total fees collected - available for withdrawal      // …    },    usd: "1250.75",    // …  },  feesBalance: {    __typename: "TokenAmount",    amount: {      __typename: "DecimalValue",      value: "100.00", // Fees currently available for withdrawal      // …    },    usd: "100.00",    // …  },  // …};
You must be the vault owner to withdraw fees.

2

Prepare the Transaction Request#

Next, create the transaction request for withdrawing fees.

Use the useVaultWithdrawFees hook to create the transaction request for withdrawing fees.

import { useWalletClient } from "wagmi";import { useVaultWithdrawFees, bigDecimal } from "@aave/react";
// …
const { data: walletClient } = useWalletClient();
const [withdrawFees, withdrawingFees] = useVaultWithdrawFees();
const result = await withdrawFees({  chainId: vault.chainId,  vault: vault.address,  amount: {    exact: bigDecimal(1000), // 1000 USDC worth of fees  },  // sendTo: evmAddress("0x1234…"), if different from vault owner});
// …

3

Send the Transaction#

Finally, send the transaction.

Use the useSendTransaction hook for the wallet library of your choice to send the transaction.

Viem
import { useWalletClient } from "wagmi";import { useVaultWithdrawFees } from "@aave/react";import { useSendTransaction } from "@aave/react/viem";
// …
const { data: walletClient } = useWalletClient();
const [withdrawFees, withdrawingFees] = useVaultWithdrawFees();const [sendTransaction, sending] = useSendTransaction(walletClient);
const loading = withdrawingFees.loading || sending.loading;const error = withdrawingFees.error || sending.error;
// …
const result = await withdrawFees({  // …}).andThen(sendTransaction);
if (result.isErr()) {  console.error("Withdraw fees failed:", result.error);} else {  console.log("Withdraw fees successful with hash:", result.value);}

Transfer Vault Ownership#

Transfer the ownership of a vault to a new address (vault owner only).

1

Identify the Vault#

First, identify the vault you want to transfer the ownership of.

Let's say we have identified a vault that we own with the following details:

Owned Vault
const vault: Vault = {  __typename: "Vault",  address: "0x1234567890abcdef1234567890abcdef12345678",  owner: "0x742d35cc6e5c4ce3b69a2a8c7c8e5f7e9a0b1234", // Your address  shareName: "Aave USDC Vault Shares",  shareSymbol: "avUSDC",  chainId: 1,  usedReserve: {    // …  },  fee: {    // …  },  totalFeeRevenue: {    // …  },  // …};
You must be the vault owner to transfer the ownership.

2

Prepare the Transaction Request#

Next, create the transaction request for transferring the ownership of the vault.

Use the useVaultTransferOwnership hook to create the transaction request for transferring the ownership of the vault.

Transfer Ownership
import { useVaultTransferOwnership, evmAddress } from "@aave/react";
// …
const [transferOwnership, transferring] = useVaultTransferOwnership();
const result = await transferOwnership({  chainId: vault.chainId,  vault: vault.address,  newOwner: evmAddress("0x1234567890abcdef1234567890abcdef12345678"),});
// …

3

Send the Transaction#

Finally, send the transaction.

Use the useSendTransaction hook for the wallet library of your choice to send the transaction.

Viem
import { useWalletClient } from "wagmi";import { useVaultTransferOwnership } from "@aave/react";import { useSendTransaction } from "@aave/react/viem";
// …
const { data: walletClient } = useWalletClient();
const [transferOwnership, transferringOwnership] = useVaultTransferOwnership();const [sendTransaction, sending] = useSendTransaction(walletClient);
const loading = transferringOwnership.loading || sending.loading;const error = transferringOwnership.error || sending.error;
// …
const result = await transferOwnership({  // …}).andThen(sendTransaction);
if (result.isErr()) {  console.error("Transfer ownership failed:", result.error);} else {  console.log("Transfer ownership successful with hash:", result.value);}
