Method Rankings by Speed
- PolyGram card on-ramp (1-2 minutes): Debit or credit card → USDC. Operational in 40+ jurisdictions worldwide. Cost structure: roughly 2.5%. Ideal scenario: newcomers seeking immediate liquidity.
- Coinbase → Polygon (2-5 minutes): Acquire USDC via Coinbase, transfer to your Polygon address. Expense breakdown: platform fees plus approximately $0.01 in Polygon network charges. Ideal scenario: established traders with existing Coinbase accounts.
- Kraken → Polygon (5-10 minutes): Obtain USDC through Kraken, dispatch to Polygon network. Favourable pricing for those transacting in EUR. Cost structure: Kraken's withdrawal tariff (amount-dependent).

FAQ
- Do I need to specify the Polygon network when withdrawing from Coinbase?
- Absolutely — ensure you designate "Polygon" (rather than Ethereum mainnet) during your USDC withdrawal to PolyGram. Mainnet alternatives are technically viable but incur substantially elevated network expenses.
- What is the minimum deposit on PolyGram?
- There exists no mandatory floor. Card on-ramp solutions ordinarily commence at $5; blockchain-based transfers carry no prescribed minimum beyond standard network fees.
