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 crypto assets can readily convert 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 (simplest approach): Exchange ETH for USDC on platforms such as Coinbase or Kraken, followed by a Polygon network withdrawal of your USDC
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH to Polygon, then execute a swap to USDC through Uniswap
- Via 1inch: Compares swap pricing across numerous Polygon-based DEXes to identify optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC in its native form, not as a bridged token. 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 exchange account confirmation.
Minimum Crypto Deposit
Polymarket does not impose a mandatory deposit floor. A realistic minimum sits around $5 in USDC to account for network fees whilst retaining sufficient capital for active trading.
