What Crypto Can You Deposit on Polymarket?
USDC on the Polygon network serves as Polymarket's primary deposit asset. Direct deposits of ETH, BTC, and alternative cryptocurrencies are not supported. That said, UK-based traders holding other digital assets can readily convert to USDC through either a decentralised or traditional exchange ahead of funding their account.
How to Convert ETH to USDC for Polymarket
- Via a CEX (easiest): Exchange ETH for USDC on platforms such as Coinbase or Kraken, followed by withdrawing USDC directly to the Polygon chain
- Via Uniswap on Polygon: Use the Polygon bridge to move ETH across to Polygon, then execute a swap to USDC through Uniswap's interface
- Via 1inch: Leverages aggregation across numerous Polygon-based DEXes to surface optimal swap pricing
USDC Networks: Polygon vs Ethereum
Polymarket operates exclusively with Polygon USDC in its native form, not as a bridged token. Ensure USDC is being sent across the Polygon network rather than the Ethereum mainnet. Transferring Ethereum-native USDC to a Polygon-addressed wallet will trigger 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 not permitted. First convert BTC into USDC through a UK-regulated exchange, then move the USDC across the Polygon network. Completion typically occurs within 30 minutes following successful exchange verification.
Minimum Crypto Deposit
Polymarket imposes no formal deposit floor. From a practical standpoint, approximately $5 in USDC represents a reasonable entry threshold, accounting for network fees whilst preserving sufficient capital for active trading positions.
