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 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.
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 if your transaction was successful. If the transaction was confirmed, you will receive the USDC in approximately 10 minutes!
The network fee is comprised of 1) the 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).
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.
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.

Transak has limits on the amount of USDC purchased depending on your location. Check if you are able to use this method . If the problem persists, please contact Transak .
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 to process your deposit. We apologize for the inconvenience and confusion this may have caused.
