FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Absolutely — ensure you choose "Polygon" (rather than Ethereum mainnet) when sending USDC to PolyGram. Mainnet transfers are supported but incur substantially higher gas expenditure.
- What is the minimum deposit on PolyGram?
- There is no mandatory floor. The card on-ramp generally accepts deposits starting at $5; digital asset transfers carry no floor beyond applicable blockchain fees.
