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 (simplest approach): Exchange ETH for USDC on platforms such as Coinbase or Kraken, then withdraw your USDC to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to transfer ETH to Polygon, then execute a swap to USDC through Uniswap
- Via 1inch: Compares swap pricing across numerous DEXes operating on Polygon to find optimal rates
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC (in its native form, not wrapped). Ensure you transfer USDC across the Polygon network specifically, rather than from Ethereum's main chain. Transferring Ethereum-based 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?
This is not an option in its direct form. You must first convert BTC into USDC through a UK-regulated exchange, then send your USDC across the Polygon network. Completion typically occurs within half an hour following successful exchange verification.
Minimum Crypto Deposit
Polymarket does not impose a strict minimum deposit requirement. In practical terms, around $5 worth of USDC represents a sensible floor, accounting for transaction costs whilst preserving sufficient capital for active trading.
