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 crypto platform ahead of their deposit.
How to Convert ETH to USDC for Polymarket
- Via a CEX (simplest approach): Exchange ETH for USDC on platforms like Coinbase or Kraken, then withdraw your USDC directly to Polygon
- Via Uniswap on Polygon: Move ETH across to Polygon using the official Polygon bridge, then execute a swap to USDC through Uniswap
- Via 1inch: Pools liquidity across multiple Polygon-based DEXes to identify optimal swap pricing
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 ERC-20 USDC from Ethereum to a Polygon-based address will lead to permanent loss.
- ✅ 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 exchange your BTC for USDC through a UK-regulated exchange, then send the resulting USDC across the Polygon network. The entire conversion and transfer typically completes within half an hour once your exchange identity verification is finished.
Minimum Crypto Deposit
Polymarket does not impose a formal minimum deposit threshold. In practice, depositing roughly $5 worth of USDC represents a sensible floor, allowing sufficient room for transaction costs whilst retaining adequate funds for active trading.
