Metamask: Metamask Chrome Extension Cannot Send Deployed ERC721 Tokens
As a developer building applications on the Binance Smart Chain (BSC) testnet or mainnet, deploying ERC-721 tokens can be a straightforward process. However, when using a Metamask Chrome extension to interact with these assets, users often encounter issues sending deployed ERC721 tokens. In this article, we will explore why this might be happening and provide some troubleshooting steps to resolve the issue.
Issue:
- ERC-721 Token Not Found: When deploying an ERC-721 token using the MetaMask Chrome extension on the BSC testnet or mainnet, the token is not automatically listed in the Metamask browser’s list of deployed assets.
- Send button is grayed out: Even when the token is found, the Send button does not work as expected.
Why this happens:
- Token list not updated: When you deploy an ERC-721 token using MetaMask Chrome, the token metadata (e.g. contract address) and ABI are stored in your browser’s local storage. However, when you try to interact with this token on another chain or platform that uses a different token registry or ABI, the token may not be listed correctly.
- Token not configured for interactions: The
erc721
module in MetaMask Chrome requires specific configuration settings to interact with deployed ERC-721 tokens. If these settings are not configured correctly, they can cause issues with sending and receiving token balances.
Troubleshooting Steps:
To resolve the issue, try the following:
Step 1: Update MetaMask Chrome to the latest version
Make sure you are running the latest version of MetaMask Chrome on your browser. You can check for updates in your browser settings or by searching for “MetaMask Chrome” in the search bar.
Step 2: Check your token list and configuration
- Update token list: Refresh the token list in your browser to ensure that it contains all deployed assets, including ERC-721 tokens.
- Configure MetaMask Chrome for interactions: Review the
erc721
module configuration settings in your MetaMask Chrome profile:
o.
Contract Address: Verify that you are using the correct contract address for the deployed token.
b.
ABI: Ensure that you have configured the ABI (Application Binary Interface) correctly.
Step 3: Use a different browser or platform
Try interacting with the ERC-721 token on a different browser or platform to see if the issue persists:
- Alternate browser: Switch to an alternative browser, such as Brave or Firefox.
- Alternate platform
: Try deploying and sending tokens on a different blockchain or network, such as the Ethereum mainnet.
Step 4: Check the token metadata
If you are still experiencing issues after updating MetaMask Chrome and refreshing the token list, try checking the metadata of your deployed ERC-721 token:
- Open the contract in the console (F12) and inspect the
contractAddress
property.
- Check that the contract address matches the one displayed in the browser.
Additional Tips
- Make sure you have the latest version of MetaMask Chrome installed on your device.
- If you are using a development environment, make sure you have the required dependencies (e.g. Web3.js) configured correctly.
- If none of these steps resolve the issue, we recommend contacting the MetaMask support team for further assistance.
By following these steps and troubleshooting tips, you should be able to resolve the issue with sending ERC-721 tokens deployed using the Metamask Chrome extension on the BSC testnet or mainnet.
