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 exchange or a traditional exchange platform before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (easiest): Trade ETH for USDC on platforms like Coinbase or Kraken, then withdraw your USDC to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH to Polygon, then exchange it for USDC through Uniswap's interface
- Via 1inch: Finds optimal swap routes by comparing rates across multiple Polygon-based decentralised exchanges
USDC Networks: Polygon vs Ethereum
Polymarket exclusively accepts Polygon USDC in its native form, not as a bridged token. Ensure you transfer USDC specifically on the Polygon network rather than the Ethereum mainnet. Transferring Ethereum-based USDC to a Polygon address will lead to permanent loss of those 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 unavailable. First convert your BTC to USDC through a UK-regulated exchange, then send the USDC across the Polygon network. This entire workflow typically completes within 30 minutes after your exchange account has been fully authenticated.
Minimum Crypto Deposit
There is no mandated minimum deposit threshold on Polymarket. In practical terms, approximately $5 worth of USDC represents a sensible floor—sufficient to account for network fees whilst preserving adequate funds for active trading positions.
