- Kraken → Polygon (5-10 minutes): Obtain USDC through Kraken, transmit to Polygon chain. Attractive pricing for those trading in EUR. Cost: Kraken's withdrawal fee (amount-dependent).

FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Absolutely — ensure you choose "Polygon" (rather than the Ethereum main chain) during your USDC withdrawal to PolyGram. Mainnet Ethereum transfers will succeed but incur substantially higher gas expenditure.
- What is the minimum deposit on PolyGram?
- There is no deposit floor. The card on-ramp typically accepts transactions starting at $5; blockchain-based transfers carry no imposed minimum beyond the cost of network validation.
