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. Nonetheless, UK-based participants holding alternative crypto assets can readily convert to USDC through either a decentralised exchange or a traditional exchange operator before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (easiest): Exchange ETH for USDC on platforms such as Coinbase or Kraken, followed by withdrawal of USDC on the Polygon chain
- Via Uniswap on Polygon: Transfer ETH to Polygon using the official Polygon bridge tool, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Leverages price aggregation across numerous DEX liquidity pools operating on Polygon
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (not wrapped or bridged variants). Ensure that USDC transfers originate from the Polygon chain, not the Ethereum base layer. Transferring ERC-20 USDC from Ethereum to a Polygon-based address will result in permanent loss of those 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 BTC into USDC through a UK-regulated exchange, then transfer the resulting USDC on Polygon. Completion typically occurs within 30 minutes following account verification.
Minimum Crypto Deposit
Polymarket does not impose a mandatory minimum deposit threshold. A practical floor of approximately $5 in USDC allows coverage of network transaction costs whilst maintaining sufficient capital for active trading engagement.
