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 possible but incur substantially higher network fees.
- What is the minimum deposit on PolyGram?
- There is no deposit floor. The card on-ramp generally accepts amounts starting at $5; blockchain-based transfers carry no floor except for network gas requirements.
