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 other digital assets can readily convert to USDC through either a decentralised or centralised exchange platform ahead of funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest option): Exchange ETH for USDC on platforms such as Coinbase or Kraken, then withdraw your USDC to the Polygon chain
- Via Uniswap on Polygon: Move ETH across to Polygon using the official bridge, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Compares swap pricing across numerous Polygon-based DEXes to secure optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure your USDC transfer targets the Polygon network specifically, rather than Ethereum's 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 into USDC via a UK-regulated exchange, then move the USDC to Polygon. The entire operation typically completes in under 30 minutes following successful exchange verification.
Minimum Crypto Deposit
Polymarket imposes no formal deposit floor. A realistic minimum sits around $5 in USDC—sufficient to absorb network fees whilst leaving adequate capital for active market participation.
