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 alternative digital assets can readily convert to USDC through either a decentralised exchange or a traditional crypto 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: Move ETH across to Polygon using the official bridge, then execute a swap to USDC on Uniswap
- Via 1inch: Finds optimal swap pricing by scanning liquidity pools across numerous Polygon-based DEXes
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (not wrapped or bridged versions). Ensure you transfer USDC specifically on the Polygon chain, rather than the Ethereum main chain. Transferring ERC-20 USDC to a Polygon address will cause your funds to be irretrievable.
- ✅ 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 an option at present. First convert your BTC into USDC through a UK-regulated exchange, then move the USDC to Polygon. Completion typically occurs within half an hour following account verification.
Minimum Crypto Deposit
Polymarket imposes no formal minimum deposit threshold. A realistic floor sits around $5 USD in USDC—sufficient to absorb network fees while preserving adequate funds for active trading.
