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 investors holding other digital assets can readily convert to USDC through either a decentralised exchange or a traditional crypto platform before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest method): Exchange ETH for USDC on platforms such as Coinbase or Kraken, then initiate a withdrawal of USDC to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto Polygon, then execute a token swap to USDC through Uniswap
- Via 1inch: Leverages liquidity across numerous decentralised protocols on Polygon to secure optimal exchange rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (not wrapped or bridged variants). Ensure you transfer USDC specifically on the Polygon network rather than the Ethereum main chain. Transferring Ethereum-based USDC to a Polygon-compatible address will permanently forfeit your funds.
- ✅ Polygon USDC (MATIC network) → use this
- ⚠️ Ethereum USDC (ERC-20) → requires bridging before use on Polymarket
Can You Deposit BTC on Polymarket?
Direct BTC deposits are unavailable. Instead, convert BTC into USDC using a UK-regulated exchange, then move the USDC to Polygon. Completion typically occurs within half an hour following account verification.
Minimum Crypto Deposit
No strict minimum deposit threshold exists on Polymarket. A realistic floor sits near $5 in USDC once you account for network fees, leaving sufficient balance for active trading.
