Safe{Wallet} Integration Architecture

Zero Hot-Wallet Private Keys on Your Web Servers

Simply paste your deployed Safe{Wallet} address per EVM chain inside XPayr Dashboard. Incoming 99.5% ERC-20 and native splits land straight inside your M-of-N multisig with $0 sweep gas.

Chain-Specific Safe Deployment Safety Guardrails

Because smart-contract multisig addresses can differ across EVM networks unless deterministically deployed, XPayr lets CFOs map distinct Safe addresses per chain and preview routes in /tools/multisig-treasury-router-planner.

B2B Buyer Checkout & Batch Центр выплат Compatibility

Enterprise buyers connect Safe{Wallet} via WalletConnect v2 (EIP-1271 signatures) to settle B2B invoices (/invoices), while merchants sign 500+ recipient Центр выплат batches (/payouts) directly from Safe.

High-Conversion Merchant Use Cases

B2B SaaS treasuries, Web3 foundations, DAOs, multi-vendor marketplaces, and CFO-governed M-of-N corporate revenue vaults.

Корпоративный мультисиг Safe{Wallet} Checkout — Часто задаваемые вопросы

Can XPayr settle 99.5% of customer checkouts directly into our Safe{Wallet} multisig?

Yes. Configure your Safe address on each target EVM chain (such as Base, Arbitrum, Optimism, Polygon, or Ethereum). Standard ERC-20 transfers and XPayr PaymentSplitter calls credit your Safe contract directly without requiring any Safe signer to be online.

Important: Can we reuse our Ethereum Safe address on Arbitrum or Base automatically?

Only if you have explicitly deployed the Safe smart contract at that exact same address on the destination Layer-2! Always verify Safe deployment per chain using /tools/multisig-treasury-router-planner before enabling live traffic.

Can B2B clients also pay XPayr invoices from their own Safe{Wallet}?

Yes — B2B buyers pair Safe{Wallet} via WalletConnect v2 or pay via Direct QR transfer from their multisig queue.
