What Crypto Can You Deposit on Polymarket?
Polymarket's primary supported asset is USDC deployed on the Polygon blockchain. Direct deposits of ETH, BTC, or alternative cryptocurrencies are not permitted. That said, UK-based traders holding alternative digital assets can readily convert to USDC through either a decentralised exchange or a traditional exchange platform ahead of their deposit.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest route): Trade ETH for USDC on platforms such as Coinbase or Kraken, then move your USDC to Polygon
- Via Uniswap on Polygon: Move ETH across to Polygon using the official bridge, then exchange it for USDC on Uniswap
- Via 1inch: Finds optimal swap pricing by pulling liquidity from numerous DEXes operating on Polygon
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped or bridged). Ensure your USDC transfer targets the Polygon chain specifically, not the Ethereum main chain. Transferring Ethereum-native USDC to a Polygon-based address will lead to 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?
This is not supported as a direct method. Transform your BTC into USDC via a UK-regulated exchange first, then send the USDC across Polygon. The entire conversion and transfer typically completes within 30 minutes following account verification.
Minimum Crypto Deposit
Polymarket enforces no formal minimum deposit threshold. A realistic floor sits near $5 worth of USDC once you factor in transaction costs, leaving you with adequate funds for active trading on live sports markets.
