Why are there fees to deposit and withdraw my USDC and 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 Getting Started.A
Fees are paid directly to miners and relayers. Polymarket does not take any fees from deposits and withdrawals.
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. 
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!
How is the network fee calculated? 
The network fee is comprised of 1) the Ethereum gas fee and 2) the relayer fee. The Ethereum gas fee is a systematic fee that is required to send funds from one wallet address to another. This fee is traditionally paid in ETH and is an additional cost. Our deposit method takes a USDC fee from the existing deposit amount, saving you time and getting rid of the need to pay in an entirely separate currency.
Direct USDC deposits are fully decentralized, meaning that any person can decide to help Polymarket provide this service. People are incentivized to help through a relayer fee. The relayer fee will be either (1) $3 + the network fee or (2) 0.3%, depending on which is higher. If the gas fee is 10 USDC, that means that the relayer fee will default to 3 USDC unless the deposit is greater than 4,333.33 USDC (4,333 * 0.3% = 10 + 3). 
How do I know if a Peer-to-peer user is trustworthy? 
There has been no report of a user scamming another user since we have implemented the peer-to-peer system. To verify a user, you can join our Discord and type ,p2p in the #peer-to-peer channel to verify if a user has completed P2P transactions in the past. You can also 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? 
Transak has limits on the amount of USDC purchased depending on your location. Check if you are able to use this method here. If the problem persists, please contact Transak here. 
I had an old, pending manual deposit/withdrawal and I can't find it anymore. What happened to my funds?
We have recently upgraded our deposit processes to allow users to pay in USDC rather than ETH, which affects users who were using our legacy system involving the ETH network fee. Please head to https://manual.polymarket.com/ to process your deposit. We apologize for the inconvenience and confusion this may have caused. 
10 minutes have passed and I still haven't received my funds. 
If you are waiting for a Hop withdrawal, please email [email protected] with the amount of USDC you were withdrawing and the destination address. If you are waiting for a Manual or MetaMask deposit, there may be network congestion and your funds will arrive in a few minutes. Please contact [email protected] if the issue persists.
