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 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 approach): Exchange ETH for USDC on platforms such as Coinbase or Kraken, then withdraw your USDC directly to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto Polygon, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Compares swap pricing across numerous Polygon-based decentralised exchanges to secure optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure your USDC transfer targets the Polygon network specifically, rather than Ethereum's mainnet. Transferring Ethereum-native USDC to a Polygon-compatible address will permanently forfeit those 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. First convert your BTC into USDC through a UK-regulated exchange, then move the USDC across the Polygon network. This entire conversion and deposit process typically completes within half an hour following successful exchange verification.
Minimum Crypto Deposit
There is no stipulated floor for account funding on Polymarket. In practice, depositing approximately $5 worth of USDC represents a sensible entry point, allowing sufficient capital for trading after accounting for network transaction costs.
