## Token Approval

Token approval allows the Limora smart contract to move USDC from your wallet. This is a standard ERC-20 security feature.

### Approval Options

When approving, you can choose:

<Tabs>
  <Tab title="Exact Amount">
    Approve only the amount you're depositing. - More secure - Requires
    re-approval for each deposit
  </Tab>

  <Tab title="Unlimited">
    Approve unlimited spending. - More convenient - Only approve once - Standard
    practice for trusted protocols
  </Tab>
</Tabs>

### Revoking Approval

To revoke Limora's approval:

1. Visit [Revoke.cash](https://revoke.cash)
2. Connect your wallet
3. Find Limora in your approvals list
4. Click "Revoke"

## Security Considerations

<AccordionGroup>
  <Accordion title="Smart contract risk">
    Deposited funds are held in audited smart contracts. However, no code is
    100% risk-free. Only deposit funds you can afford to lose.
  </Accordion>

  <Accordion title="Approval safety">
    Only approve tokens for the official Limora contract. Verify contract
    addresses on the [Addresses](/protocol/addresses) page.
  </Accordion>

  <Accordion title="Phishing prevention">
    Always access Limora through the official URL. Never approve transactions
    from links in DMs or emails.
  </Accordion>
</AccordionGroup>

***

## Troubleshooting

<AccordionGroup>
  <Accordion title="Approval transaction failing">
    * Ensure you have ETH for gas - Try increasing gas limit - Check that you
      haven't already approved
  </Accordion>

  <Accordion title="Deposit not showing">
    * Wait for transaction to confirm on Base - Refresh the page - Check
      transaction status on Basescan
  </Accordion>

  <Accordion title="Insufficient balance error">
    * Verify you have enough USDC in wallet - Account for gas fees (need ETH) -
      Try depositing a smaller amount
  </Accordion>
</AccordionGroup>
