Method Rankings by Speed
- PolyGram card on-ramp (1-2 minutes): Debit or credit card → USDC. Supported across 40+ territories worldwide. Cost: roughly 2.5%. Ideal for: newcomers seeking immediate liquidity.
- Coinbase → Polygon (2-5 minutes): Acquire USDC via Coinbase, transfer to your Polygon address. Cost: platform fee plus approximately $0.01 in Polygon network charges. Ideal for: active traders with existing Coinbase accounts.
- Kraken → Polygon (5-10 minutes): Obtain USDC on Kraken, dispatch to Polygon. Attractive pricing for those trading in EUR. Cost: Kraken's withdrawal charge (amount-dependent).

- Bank transfer → exchange → Polygon (1-3 days): Most economical per unit for substantial sums but requires patience. Ideal for: single deposits of $5,000 or higher.

FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Absolutely — ensure you choose "Polygon" (rather than Ethereum mainnet) when moving USDC to PolyGram. Mainnet transfers are possible but incur substantially higher network costs.
- What is the minimum deposit on PolyGram?
- There is no floor requirement. The card on-ramp generally permits deposits starting at $5; blockchain transfers carry no minimum beyond applicable network charges.
