Coinbase Wallet & Smart-Wallet Checkout — Häufig gestellte Fragen

Why accept Coinbase Wallet via XPayr instead of Coinbase Commerce?

XPayr charges half the gateway fee (0.5% vs 1.0%), remains 100% non-custodial across 12 networks (including TRON TRC-20, BNB Chain, TON, and Solana), and includes Direkter Börsen-QR plus 21 MCP tools.

Does XPayr support ERC-2612 Gasless USDC on Base for Coinbase Wallet users?

Yes. Base native USDC supports EIP-2612 permits, allowing gas-sponsored checkout when merchant Fee Delegation (/gasless) is active.

Can European Coinbase Wallet users pay in MiCA-aligned EURC?

Yes. XPayr supports native Circle EURC on Base, Ethereum, Solana, Avalanche, and Circle Arc at the same 0.5% flat split.
