What Crypto Can You Deposit on Polymarket?
Polymarket's primary settlement asset is USDC deployed on the Polygon blockchain. 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 using either a decentralised exchange or a traditional cryptocurrency exchange before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): Trade ETH for USDC on platforms such as Coinbase or Kraken, then withdraw the USDC to your Polygon wallet
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto the Polygon network, then execute a swap to USDC through Uniswap
- Via 1inch: Compares swap prices across numerous decentralised exchanges operating on Polygon to identify optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (not wrapped or bridged versions). Ensure you transfer USDC specifically on the Polygon network, not the Ethereum main chain. Transferring Ethereum-based USDC to a Polygon-compatible address will cause 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?
This is not an option through direct deposit. You must first exchange BTC for USDC on a UK-regulated exchange, then move the USDC to Polygon. The entire conversion and transfer workflow typically completes in under 30 minutes following account verification.
Minimum Crypto Deposit
Polymarket does not enforce a deposit floor. A sensible practical threshold sits around $5 in USDC to account for network transaction costs whilst retaining sufficient capital for active trading.
