Kraken Integration Architecture

Preferred Exchange Corridor for US, UK & EU MiCA Buyers

Kraken is a primary regulated venue for North American and European corporate clients paying B2B invoices in Circle USDC, Euro Coin (EURC), ETH, SOL, or BTC.

Low-Fee Arbitrum, Optimism, Polygon & Solana Withdrawals

Kraken supports native L2 and Solana USDC withdrawals, and XPayr 1% ($0.50 max) tolerance ensures minor withdrawal fee deductions never block order fulfillment.

QuickBooks, Xero, NetSuite & EU MiCA Audit Readiness

Every Kraken QR or Kraken Wallet checkout produces a deterministic @xpayr/payment-evidence receipt with tx_hash, timestamp, gross amount, and 0.5% fee split (/accounting).

High-Conversion Merchant Use Cases

European & North American B2B invoices (/invoices), software & consulting retainers, EU MiCA EURC commerce (/compliance), and high-ticket travel.

Exchange Kraken y Billetera Kraken Checkout — Preguntas frecuentes

Can European clients withdraw EURC or USDC from Kraken to pay an XPayr invoice?

Yes. Clients select EURC or USDC on a matching supported network (such as Ethereum, Arbitrum, Polygon, Base, or Solana), scan the XPayr Direct QR code, and settle straight to your non-custodial wallet.

Does XPayr also support the self-custodial Kraken Wallet mobile app?

Yes — Kraken Wallet connects via WalletConnect v2 / EIP-6963 and Solana Wallet Standard for 1-click Web3 signing.

How do our accountants reconcile incoming Kraken client payments?

Export balanced double-entry CSV/JSON ledgers for QuickBooks, Xero, and NetSuite directly from XPayr (/tools/crypto-accounting-export-simulator) complete with on-chain tx_hash verification.
