If you withdrew to an external wallet and your balance isn't showing up, the wallet likely hasn't auto-detected the token yet. This is a common issue and doesn't mean your funds are lost.
To fix it, you'll need to manually add the token to your wallet:
MetaMask Example
Open MetaMask and go to the Tokens tab
Click on the three dots
Select Import tokens
Select Custom token
Enter the token contract address
MetaMask will fill in the token symbol and decimals automatically
Tap Add custom token
If you sent to the correct address but chose a different network from the one your wallet is set to, switch your wallet to that network and check again. The network is shown next to Delivered on in your Plasma One transaction history. If the funds still don't appear, contact our support team through the app.
