Platform-by-Platform Comparison
1. PolyGram — Best for International Users
PolyGram at polygram.ink delivers a streamlined gateway to Polymarket's underlying liquidity pools. Notable strengths include:
- Full access to Polymarket's market depth without owning a cryptocurrency wallet
- Direct fiat payment channels via debit and credit cards — no need to purchase USDC beforehand

Polymarket commands over $100M in weekly turnover, establishing itself as the globe's most liquid prediction venue. Entry requires a blockchain wallet (MetaMask or equivalent) and USDC holdings.

Restricted to US-based users undergoing identity authentication. Bid-ask spreads tend to be marginally wider relative to Polymarket offerings.
