Deposits & Withdrawals

What are Ethereum gas fees? Why do I need to pay them?

To interact with the Ethereum blockchain, users have to pay gas to have their transactions processed. This is true for any application built on Ethereum that is performing a transaction on the blockchain.

For Polymarket users, there are two times where they will have to pay gas fees: (1) when depositing funds and (2) when withdrawing funds. For more details, see the “Getting Started” section above.

I deposited USDC using MetaMask but my funds aren't appearing.

If this was your first time using MetaMask on Polymarket, you paid a one-time fee to authorize USDC on Polymarket. Please initiate the deposit again!

If this is not your first time using MetaMask, check etherscan.io if your transaction was successful. If the transaction was confirmed, you will receive the USDC in approximately 10 minutes!

Why did the network fee become more or less expensive?

The Ethereum network can process a limited number of transactions per second. Those transactions are selected by the amount of gas the user is willing to pay from highest to lowest. Generally, the price of gas increases when there is greater demand across the network and decreases when the network is less congested.

How do I know if another user is trustworthy?

There has been no report of a user scamming another user since we have implemented the peer-to-peer system. However, we strongly recommend that you search from:[username] in the top right of our Discord to check that they are an active participant and have completed a P2P transaction in the past.

Why is my debit or credit card not working?

Users located in the US cannot use this method. Check if you are able to use this method here.

Why can I only pay in Euros with a debit/credit card?

We only accept debit and credit card payments in Euros because USD is restricted due to compliance issues.
