Need help getting started with deposits and withdrawals? You’ve come to the right place

We are beyond excited to see so many Ethereum-based applications take off over the past year. Whether it’s crypto art, NFTs, or decentralized finance (DeFi) apps, we are proud to be part of a broader movement that is making blockchain-based applications more accessible to the public

However, increased network usage means higher Ethereum gas costs than ever before. As a result, depositing and withdrawing funds on Polymarket require higher transaction fees as well

Note: Polymarket does not take fees. These fees are paid to facilitate transactions on the Ethereum blockchain

In this guide, we will walk through the easiest and cheapest ways to (1) deposit and (2) withdraw funds to and from your Polymarket account

Depositing Funds

There are 4 ways to deposit funds into your Polymarket account:

  1. MetaMask Deposit (Easiest)
  2. Peer-to-Peer (Cheapest)
  3. Manual Deposit (Currently expensive)
  4. Debit or Credit Card (for non-US residents)

The easiest self-serve option for a new user is MetaMask Deposit. The option with the lowest fees is Peer-to-Peer, but this will require coordinating with a community member

Note: Keep in mind that withdrawing funds will also incur transaction fees

MetaMask Deposit (Easiest)

To deposit funds via MetaMask, you will need the following:

  • MetaMask wallet: Stores USDC and ETH
  • USDC: Funds you will be depositing into your Polymarket wallet
  • ETH: Used to pay transaction fees to transfer USDC to your Polymarket wallet

Steps for MetaMask Deposit (Easiest Option for New Users)

  1. Install MetaMask on a supported browser (MetaMask FAQs)
  2. Send USDC to your MetaMask wallet from an exchange like Coinbase (Your wallet address can be found at the top of your MetaMask screen)
  3. Purchase ETH for the two transaction fees below via MetaMask by using your debit card with Wyre (Click “Buy” and “Continue to Wyre”)
  4. The ETH is used to pay for (a) the first-time user authorization fee and (b) the transaction fee to move your USDC into your Polymarket account [An estimate of the ETH required to transfer your USDC is shown when selecting MetaMask Deposit]
  5. Once you have USDC and enough ETH in your MetaMask account, go to the Deposit page and select “MetaMask Deposit”
