What Crypto Can You Deposit on Polymarket?
Polymarket accepts USDC as its primary deposit asset on the Polygon blockchain. Direct deposits of ETH, BTC, and alternative cryptocurrencies are not supported. That said, UK-based traders holding alternative digital assets can readily convert their holdings to 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 (easiest): Exchange your ETH for USDC on platforms such as Coinbase or Kraken, then withdraw the USDC directly to Polygon
- Via Uniswap on Polygon: Move your ETH across to Polygon using the official Polygon bridge, then execute a swap to USDC through Uniswap
- Via 1inch: Leverages pricing across multiple decentralised exchanges on Polygon to identify optimal swap opportunities
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure you are transferring USDC specifically on the Polygon chain, rather than the Ethereum mainnet version. Mistakenly sending mainnet USDC to a Polygon destination will permanently forfeit your 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 available option. You will need to liquidate your BTC to USDC through a UK-regulated exchange first, followed by transferring the resulting USDC on Polygon. Typically, this entire workflow completes within half an hour once your exchange identity verification is finished.
Minimum Crypto Deposit
Polymarket does not impose a set minimum deposit threshold. In practical terms, approximately $5 worth of USDC represents a sensible baseline, allowing you to absorb transaction fees whilst retaining sufficient capital for active trading.
