What Crypto Can You Deposit on Polymarket?
USDC on the Polygon network serves as Polymarket's primary deposit asset. Direct deposits of ETH, BTC, or alternative cryptocurrencies are not supported. That said, UK-based traders holding other digital assets can readily exchange them for USDC through either a decentralised exchange (DEX) or a traditional centralised exchange before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): Exchange ETH for USDC on platforms like Coinbase or Kraken, then withdraw your USDC to the Polygon network
- Via Uniswap on Polygon: Transfer ETH to Polygon using the official Polygon bridge, then trade it for USDC directly on Uniswap
- Via 1inch: Compares swap pricing across numerous DEXes operating on Polygon to find optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (not a bridged version). Ensure you are transferring USDC specifically on the Polygon network rather than the Ethereum mainnet. Attempting to send mainnet Ethereum-based USDC to a Polygon address will lead to permanent loss of those funds.
- ✅ Polygon USDC (MATIC network) → use this
- ⚠️ Ethereum USDC (ERC-20) → requires bridging before use on Polymarket
Can You Deposit BTC on Polymarket?
This is not a supported option. You will need to convert BTC into USDC using a UK-regulated exchange first, then move your USDC to the Polygon network for deposit. Completion of this entire workflow typically takes fewer than 30 minutes after your exchange account has been fully verified.
Minimum Crypto Deposit
There is no formally set minimum deposit requirement on Polymarket. In practical terms, approximately $5 worth of USDC represents a reasonable floor, as this amount allows for transaction fees whilst preserving sufficient capital for actual trading activity.
