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 to USDC through either a decentralised exchange or a traditional crypto platform 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 to the Polygon chain
- Via Uniswap on Polygon: Port ETH across to Polygon using the official bridge protocol, then execute a swap to USDC through Uniswap
- Via 1inch: Leverages price discovery across numerous Polygon-based DEXes to surface optimal swap pricing
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure your USDC transfer targets the Polygon network specifically, rather than Ethereum's main chain. Routing Ethereum-native USDC to a Polygon destination 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'll need to liquidate BTC into USDC on a UK-regulated exchange first, then move USDC across to Polygon. Completion typically occurs within half an hour once your exchange identity verification is finalised.
Minimum Crypto Deposit
Polymarket does not impose a mandatory deposit floor. In practical terms, approximately $5 worth of USDC represents a reasonable entry point—sufficient to absorb transaction costs whilst retaining adequate funds for active trading positions.
