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 exchange or a traditional cryptocurrency exchange before funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (easiest): Trade ETH for USDC on platforms such as Coinbase or Kraken, then withdraw your USDC to the Polygon network
- Via Uniswap on Polygon: Move ETH to Polygon using the official Polygon bridge, then exchange it for USDC through Uniswap
- Via 1inch: Compares swap pricing across numerous Polygon-based decentralised exchanges to find optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not as a wrapped or bridged token). Ensure you are transferring USDC specifically on the Polygon blockchain, not on Ethereum's main network. Transferring Ethereum-native USDC to a Polygon-based 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. You must first exchange BTC for USDC through a UK-regulated exchange, then send the resulting USDC on Polygon to your Polymarket wallet. Completion typically occurs within 30 minutes following account verification.
Minimum Crypto Deposit
Polymarket does not enforce a deposit floor. A sensible practical threshold is approximately $5 in USDC, which allows sufficient room for transaction fees whilst preserving adequate capital for active trading positions.
