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 them 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 method): Trade your ETH for USDC on platforms such as Coinbase or Kraken, then withdraw the USDC directly to Polygon
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto Polygon, then exchange it for USDC through Uniswap
- Via 1inch: Finds optimal swap pricing by comparing rates across numerous Polygon-based decentralised exchanges
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure you transfer USDC across the Polygon network exclusively, avoiding Ethereum mainnet transfers. Attempting to send ERC-20 USDC from Ethereum to a Polygon 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?
This is not an option through direct transfer. You must first exchange BTC for USDC through a UK-regulated exchange, then move the resulting USDC across Polygon. The entire conversion and transfer typically completes within 30 minutes following account authentication.
Minimum Crypto Deposit
Polymarket does not impose a mandatory minimum threshold. In practical terms, approximately $5 worth of USDC represents a sensible floor, accounting for transaction fees whilst preserving sufficient capital for active participation.
