Why pay-castle

Built around one idea: your crypto is yours

Truly non-custodial

We never take possession of your funds. Crypto goes from Coinbase to your wallet — pay-castle is never in the middle of the money.

Compliance you can trust

Identity verification (KYC) and payment processing are performed by Coinbase, a publicly traded, regulated company — not by us.

No hidden markup

pay-castle adds no fee of its own. You see Coinbase's fee before you confirm, and nothing extra from us.

Card & Apple Pay

Pay the way you already do. Coinbase Guest Checkout supports debit/credit cards and Apple Pay — no Coinbase account required.

Fast delivery

Once payment clears, crypto is delivered on-chain to your wallet — usually within minutes on low-cost networks like Base.

Multi-network

Default to USDC on Base for low fees, or choose Polygon or Ethereum. Your address is validated before checkout.
