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 or traditional exchange before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest route): Exchange ETH for USDC on platforms such as Coinbase or Kraken, then withdraw your USDC directly to Polygon
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto the Polygon chain, then execute a swap to USDC through Uniswap
- Via 1inch: Compares swap pricing across numerous DEXes operating on Polygon to secure 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 targets the Polygon network specifically, not the Ethereum main chain. Transferring ERC-20 USDC from Ethereum to a Polygon address will cause permanent loss of 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 into USDC through a UK-regulated exchange, then transfer the resulting USDC across the Polygon network. Completion typically occurs within 30 minutes following exchange account verification.
Minimum Crypto Deposit
No formal minimum deposit threshold exists on Polymarket. A realistic floor sits around $5 in USDC to account for network fees whilst retaining sufficient funds for active trading positions.
