FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Absolutely — ensure you choose "Polygon" (rather than the main Ethereum chain) when sending USDC to PolyGram. Mainnet Ethereum transfers are supported but incur substantially higher gas expenditure.
- What is the minimum deposit on PolyGram?
- There is no required minimum. The card on-ramp gateway generally accepts deposits starting at $5; direct crypto transfers carry no floor except for whatever network costs apply.
