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 convert to USDC through either a decentralised or centralised exchange platform before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): Exchange ETH for USDC on platforms like Coinbase or Kraken, then withdraw your USDC directly to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH to Polygon, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Leverages price discovery across numerous Polygon-based DEXes to secure optimal swap pricing
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC in its native form, not as a bridged token. Verify that USDC is being transmitted on the Polygon network rather than Ethereum's mainnet. Transferring mainnet Ethereum USDC to a Polygon address will lead to permanent asset loss.
- ✅ 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 holdings to USDC through a UK-regulated exchange, then move the resulting USDC across the Polygon network. Completion typically occurs within half an hour following successful exchange verification.
Minimum Crypto Deposit
Polymarket does not impose a mandatory deposit floor. From a practical standpoint, approximately $5 worth of USDC represents a sensible entry point, allowing sufficient reserves after accounting for network fees whilst maintaining adequate funds for active trading positions.
