Metamask: Invalid amount in MetaMask app on iPhone

Metamask App Issue: Invalid Amount in MetaMask on iPhone

As a user of Moralis, you’re likely familiar with the seamless experience of transferring tokens between wallets using the MetaMask app. However, we’ve encountered a frustrating issue when trying to use it on our iPhone devices.

The problem lies in the way Metamask handles amounts and transactions in its mobile application. Specifically, the “Invalid amount” error occurs when attempting to send or receive tokens from one wallet to another, resulting in an incorrect transaction amount being displayed to the user.

Symptoms:

• The MetaMask app crashes or freezes when trying to initiate a token transfer.

• A “Invalid amount” error message appears on the screen, indicating that the transaction amount is incorrect.

• Despite having sufficient funds in your wallet, you still receive an invalid amount notification.

Root Cause:

The issue stems from the way Metamask handles amounts and transactions in its mobile application. Specifically:

• When sending or receiving tokens, Metamask attempts to validate the transaction amount against the available balance in the sender’s and recipient’s wallets.

• However, when transferring between wallets using Moralis, the MetaMask app doesn’t properly account for the token transfer fees.

Moral Solution:

To resolve this issue on your iPhone, you can follow these steps:

• Update to the latest MetaMask version: Ensure that you’re running the latest version of the MetaMask app on your iPhone. You can check for updates in the App Store.

• Disable token transfer fees: Go to Settings > Wallet & Apple Cash > Fees, and toggle off “Token transfer fee”. This will allow Metamask to use its default transfer rate, which may be more accurate than the one specified by Moralis.

• Use a custom wallet for token transfers: Consider creating a separate custom wallet in your MetaMask app that uses the same account as your main Morali wallet. This will enable you to transfer tokens using Morali’s API without encountering the invalid amount issue.

Workaround:

If updating the MetaMask app or disabling token transfer fees doesn’t resolve the issue, we recommend taking a workaround:

• Create a new custom wallet in MetaMask that mirrors your main Morali wallet.

• Use this custom wallet to transfer tokens between wallets using Morali’s API.

• When sending or receiving tokens, ensure you have sufficient funds in both wallets.

By implementing these steps, you should be able to resolve the “Invalid amount” issue and enjoy a seamless token transfer experience with Metamask on your iPhone.
