[Bug]: Cannot import tokens manually on Sepolia test network #28124

Open benjisclowder opened 3 weeks ago

benjisclowder commented 3 weeks ago

Describe the bug

I am not able to import any ERC20 tokens on Sepolia network. Tokens list is still empty after clicking "Import". This does not apply to NFTs and is specific to Sepolia and could also reproduce on Linea Sepolia.

Expected behavior

Tokens can be imported successfully.

Screenshots/Recordings

Steps to reproduce

  1. Load MetaMask
  2. Connect to a test network (Sepolia or Linea Sepolia)
  3. Create ERC20 tokens via TestDapp or load blockchain explorer to see a balance of existing tokens
  4. Copy token contract address
  5. In MetaMask, select Import Tokens
  6. Paste the contract address in the custom tokens field
  7. Click Next --> Import
  8. Notice the Token list is not updating with the imported tokens.

Although I was able to import the same token address on 12.5, the bug here is that the token does not import when you click the Next button too quickly. Before the token's information has been fetched from RPC calls.

Possibly the Next button should remain disabled until the data has been fetched.
