Take an action · Aave V4 basics

Preview, approve, confirm

Understand what each wallet step does and why a transaction may need more than one request.

4 sections Beginner friendly

Preview first

Choose an action and enter its token amount. Preview transaction asks for the proposed position result without submitting the main action. Read the health factor before and after, the resulting risk premium, and any errors.

A preview is valid for 60 seconds in this explorer. Changing the amount, action, collateral choice, or wallet context means reviewing again. A preview cannot freeze market conditions until confirmation.

Approval and action are separate

A token-spending approval permits a contract to use a token up to the authorized allowance. It is different from the supply or repayment itself. Depending on existing permissions and the action, the wallet may also request another prerequisite transaction.

Read the spender, network, amount or allowance, and fees shown by ur wallet. A confirmed approval can remain even if u reject the next request. Closing this site does not revoke a permission already recorded on-chain.

Token amount and ETH gas

The main transaction form uses the named ERC-20 token. Gas fees are paid in ETH on Ethereum and OP Mainnet, or AVAX on Avalanche. Having enough of the action token does not mean u have enough of the gas token to cover the wallet’s estimated fee.

If u are connected to another network, the form offers a Switch to button naming the selected network. Switching networks is not the same as submitting the token action. Check the network again in the wallet request.

Confirm and verify

  1. Select Confirm in wallet only after reviewing the preview.
  2. Inspect each wallet request. Reject it if it does not match the intended account, network, or action.
  3. Wait while the site reports progress. Repeated clicks do not speed up confirmation.
  4. When confirmation appears, use View transaction to inspect the receipt on that network’s block explorer.
  5. Select Refresh balances and inspect the resulting position. If a step failed, check whether an earlier approval already completed before retrying.
