FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Affirmative — ensure you designate "Polygon" (rather than Ethereum mainnet) when sending USDC to PolyGram. Mainnet transfers are supported but incur substantially higher network charges.
- What is the minimum deposit on PolyGram?
- There is no mandatory floor. The card on-ramp generally accepts deposits from $5 upwards; blockchain transfers carry no floor except for network verification and account setup requirements.
