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 exchange them for 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 option): Trade ETH for USDC on platforms such as Coinbase or Kraken, followed by withdrawing your USDC to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto Polygon, then execute a swap to USDC through Uniswap
- Via 1inch: Finds optimal swap prices by comparing rates across numerous DEXes operating on Polygon
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not via a bridge). Ensure your USDC transfer targets the Polygon network specifically, not the Ethereum mainnet. Transferring ERC-20 USDC from Ethereum to a Polygon 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?
Direct BTC deposits are not permitted. First convert your BTC to USDC through a UK-regulated exchange, then send the USDC via the Polygon network. Completion typically occurs within 30 minutes following account verification on your chosen exchange.
Minimum Crypto Deposit
Polymarket does not enforce a mandatory deposit floor. A sensible practical threshold sits around $5 in USDC, sufficient to absorb network fees whilst preserving adequate funds for active trading positions.
