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 crypto assets can readily convert to USDC through either a decentralised or traditional exchange before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (most straightforward): Exchange ETH for USDC on platforms such as Coinbase or Kraken, followed by withdrawal of USDC on the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH to Polygon, then execute a swap to USDC via Uniswap
- Via 1inch: Compares swap prices across numerous Polygon-based DEXes to identify optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC in its native form, not as a bridged token. Ensure your USDC transfer occurs on the Polygon network rather than the Ethereum mainnet. Transferring mainnet USDC to a Polygon 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. First convert your BTC to USDC through a UK-regulated exchange, then transfer the USDC via Polygon. Completion typically occurs within 30 minutes following account verification.
Minimum Crypto Deposit
Polymarket enforces no set minimum deposit threshold. A realistic floor sits around $5 in USDC, accounting for transaction fees whilst preserving sufficient capital for active trading.
