⚖️ XPayr vs Triple-A
📊 Commercial Breakdown
Cutover Time~15 Minutes (Parallel Safe)
Triple-A Fee~1.0% + institutional FX conversion spread + bank settlement
XPayr Gateway FeeFlat 0.5% ($0/mo · $0 Sweep)
XPayr Custody Model100% Non-Custodial (99.5% Direct)
Why Engineering & Finance Teams Switch Away From Triple-A
Mandatory conversion to local fiat incurs ~1.0% processing plus hidden FX conversion spreads — even when your business wants to hold USD/EUR stablecoins.
OAuth2 token refresh ceremonies and multi-week institutional KYB slow down developer integration.
T+1/T+2 bank wire holidays delay working capital for global marketplaces and suppliers.

4-Step Zero-Downtime Canary Cutover Checklist
Deploy the X-XPayr-Signature HMAC-SHA256 webhook adapter
Add the raw-body HMAC-SHA256 verification handler alongside your existing Triple-A callback endpoint and test events in /tools/webhook-tester.
Canary 10%–25% of live checkout sessions in parallel
Route a slice of live crypto orders to POST /api/v1/payments (or enable the XPayr storefront plugin) to verify instant 99.5% direct wallet settlement.
Cut over 100% of traffic & export clean ERP ledgers
Switch primary crypto checkout routing to XPayr, withdraw any remaining custodial float from Triple-A, and export QuickBooks/Xero CSVs via /accounting.
Frequently Asked Questions — Switching From Triple-A
Can our CFO settle directly into Safe{Wallet} multisig or Fireblocks MPC vaults?
Yes. Configure your Safe multisig (/wallets/safe-multisig), Squads (/wallets/squads), Ledger (/wallets/ledger), or Fireblocks (/wallets/fireblocks) deposit addresses per chain and receive 99.5% directly with zero intermediary hot-wallet risk.
How does XPayr support EU MiCA and corporate accounting compliance?
Because XPayr is 100% non-custodial software and supports Circle USDC and Euro Coin (EURC) alongside cryptographic @xpayr/payment-evidence receipts, finance teams maintain clean audit trails (/compliance & /accounting).
Can we start testing today without waiting for an enterprise sales call?
