Interactive Polygon USDC On-Ramp Fee & Net-Shares Comparator
Compare depositing native Polygon USDC via OKX / Binance (~$0.10 fee) vs. third-party credit card processors (MoonPay ~3.8% fee) across any deposit size.
01 · Tool Overview & Quantitative Mechanism
On-ramp friction is a silent killer of trading edge. Third-party credit card processors (like MoonPay) charge ~3.8% in processing fees and FX spread—costing you $38 on every $1,000 deposit before you even place a trade.
Pro traders buy USDC on OKX or Binance and withdraw over the **Polygon (POS)** network directly to their Polymarket `0x` deposit address. Network fees are ~$0.10 on OKX and ~$0.80 on Binance, arriving in under 60 seconds.
