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 cryptocurrency exchange prior to funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest route): Trade your ETH for USDC on platforms like Coinbase or Kraken, then withdraw the USDC directly to the Polygon chain
- Via Uniswap on Polygon: Move ETH across to Polygon using the official Polygon bridge, then execute a swap to USDC through Uniswap
- Via 1inch: Finds optimal swap prices by scanning liquidity across numerous Polygon-based decentralised exchanges
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped from another chain). Ensure you transfer USDC specifically on the Polygon blockchain rather than the Ethereum mainnet. Transferring mainnet 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?
This is not an option at present. First exchange your BTC to USDC through a UK-regulated exchange, then move the USDC across to Polygon. Once your exchange account is fully activated, the entire transaction typically completes within half an hour.
Minimum Crypto Deposit
There is no formal minimum deposit requirement set by Polymarket. In practical terms, around $5 worth of USDC represents a reasonable floor—sufficient to absorb transaction costs while leaving adequate funds for actual trading activity.
