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 digital assets can readily convert to USDC through either a decentralised or traditional exchange before 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 blockchain
- Via Uniswap on Polygon: Move ETH across to Polygon using the official Polygon bridge, then trade for USDC directly on Uniswap
- Via 1inch: Compares swap pricing across numerous Polygon-based DEXes to find 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 main chain. Transferring Ethereum-native USDC 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 an option. You'll need to exchange BTC for USDC through a UK-regulated exchange first, then move USDC to Polygon. Completion typically occurs within 30 minutes following successful exchange verification.
Minimum Crypto Deposit
Polymarket does not enforce a minimum deposit threshold. In practical terms, around $5 worth of USDC represents a sensible floor—sufficient to absorb network fees whilst retaining adequate funds for active market participation.
