WalletConnect Integration Architecture

Institutional Safe{Wallet} Multisig & Hardware Wallet Support

B2B finance teams paying $5,000–$250,000+ software or wholesale invoices pair Safe{Wallet} or Ledger Live via WalletConnect v2, co-sign with M-of-N signers, and settle 99.5% atomically.

CAIP-25 Namespace Negotiation Across EVM & Solana

WalletConnect v2 negotiates required and optional chain namespaces in a single QR scan, preventing stale session disconnects when buyers switch between Arbitrum, Base, and Ethereum.

Zero Custodial Relay Risk

WalletConnect v2 carries only encrypted JSON-RPC signing requests — XPayr never touches private keys, seed phrases, or intermediate funds.

High-Conversion Merchant Use Cases

Enterprise B2B invoices (/invoices), Safe multisig corporate treasuries, hardware-wallet buyers, and cross-device desktop-to-mobile checkouts.

Protocolo WalletConnect v2 (Reown) Checkout — Preguntas frecuentes

Can a corporate customer pay an XPayr B2B invoice from a Safe{Wallet} multisig?

Yes. Safe{Wallet} connects via WalletConnect v2 (or sends directly in QR Transfer Mode). Once threshold signers execute the transaction on-chain, XPayr verifica the tx_hash and marks the invoice completed.

Does WalletConnect v2 work with Ledger Live and Keystone hardware wallets?

Yes. Any WalletConnect v2 compatible companion app (Ledger Live, Rainbow, Zerion, 1inch Wallet, SafePal, TokenPocket) pairs out of the box.

What happens if a corporate multisig takes 20 minutes to gather co-signatures?

B2B invoice links (/invoices) can be configured with extended validity windows or reusable session parameters, and XPayr reconciles the exact on-chain transfer deterministically.
