2 Help - Troubleshooting

2.1 Transactions & Gas Fees

Q1. My transaction is pending on Metamask for some time now, what can I do?

If your transaction is stuck, try resetting your Metamask by clicking the account icon on the top-right corner of MetaMask → Select Settings → Select Advanced → Scroll down and click Reset Account.
Please note that resetting your account will not disrupt your funds or wallet address.

Q2. Why did my transaction fail?

If your transaction failed, it's either because you don't have enough slippage or use enough gas. You'll have to increase your allowed slippage to account for the fee taken during the swap. Click on the gear icon for settings and adjust slippage tolerance accordingly.

Q3. It says my transaction is successful, but it is not showing up.

You can use SnowTrace to track your transaction status.

Q4. Transactions are failing when using a Ledger

You need to downgrade your Metamask version to 10.0.3 using ETH app. If the issue persists, you can join Avalanche's Discord server and seek help in the ledger support channel.

Q5. "Unexpected issue with estimating the gas. Please try again"

Two different things can cause this issue.
Solution 1: Clear your browser's cache and restart your browser. (You can force a cache refresh by hitting ctrl+f5)
Solution 2: Make sure the units you're trading to don't have too many decimals points.

Q6. Internal JSON-RPC error

Make sure you have enough AVAX in your wallet to cover the gas fees.

Q7. I've sent my funds to Pangolin's router address.

Unfortunately, this action is not reversible. Please never send any tokens to Pangolin's router address.

2.2 Tokens & Balances

Q1. Why isn't my token showing in my Metamask wallet?

If you can't see your token, you'll need to go to "Assets" tab on Metamask and add it by clicking on "import tokens". (It's at the bottom of the app, right below "don't see your token?") Paste the contract address inside Metamask and tap next.

Q2. Why isn’t my ERC-20 token showing in my Metamask wallet?

This is due to the token address changing. When you transfer ERC-20’s across the Avalanche-Ethereum Bridge, the Token contract address changes. Token contract addresses are different on Ethereum and Avalanche despite being the same represented token.

Q3. I can't see my LP tokens

Once you deposit your tokens to a pool, you'll get LP tokens. If you deposit your LP tokens to a farm, that means your LP tokens have been deposited to a Pangolin contract. Since they're no longer in your wallet, you can't see them, which is completely normal. If you want to convert your LP tokens into tokens, you'll need to unstake your LP tokens from the farm+pool.

2.3 Website Access

Q1. I can't connect my wallet to Pangolin on mobile.

You need to download and use Metamask's in-app browser to use Pangolin on your phone.
