What Crypto Can You Deposit on Polymarket?
USDC operating 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 exchange them for USDC through either a decentralised exchange or a traditional exchange platform before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): 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 across to Polygon, then execute a swap to USDC through Uniswap
- Via 1inch: Compares swap pricing across numerous Polygon-based DEXes to identify optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, without bridging). Ensure you are transferring USDC specifically on the Polygon network rather than the Ethereum main chain. Transferring Ethereum-based USDC to a Polygon-compatible 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 not available. First convert BTC into USDC using a UK-regulated exchange, then move your USDC across the Polygon network. This entire sequence typically completes in under half an hour following successful exchange verification.
Minimum Crypto Deposit
There is no stipulated minimum deposit requirement on Polymarket. In practical terms, approximately $5 worth of USDC represents a sensible floor—sufficient to absorb transaction costs whilst preserving adequate funds for active trading positions.
