What Crypto Can You Deposit on Polymarket?
Polymarket's primary settlement asset is USDC on the Polygon network. 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 exchange or a traditional exchange operator before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): Trade your ETH for USDC on platforms such as Coinbase or Kraken, then withdraw the resulting USDC directly to Polygon
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH onto the Polygon chain, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Leverages liquidity aggregation to surface optimal swap pricing across numerous Polygon-based decentralised venues
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon-native USDC (non-bridged variant). Ensure you are transferring USDC across the Polygon chain, not the Ethereum main chain. Mistakenly routing Ethereum mainnet USDC to a Polygon destination will result in permanent loss.
- ✅ Polygon USDC (MATIC network) → use this
- ⚠️ Ethereum USDC (ERC-20) → requires bridging before use on Polymarket
Can You Deposit BTC on Polymarket?
Polymarket does not accept BTC directly. First convert your BTC into USDC through a UK-regulated exchange, then move the USDC across Polygon. Completion typically occurs within 30 minutes following successful exchange verification.
Minimum Crypto Deposit
Polymarket enforces no formal minimum deposit threshold. A realistic floor sits near $5 in USDC once gas expenses are factored in, leaving adequate reserves for active market participation.
