Clicking Approve Payment triggers a WalletConnect v2 session. A unique, time-limited QR code is generated as a cryptographically signed relay bridge between this interface and your client's wallet. Every session is single-use and expires automatically.

Your client opens the Binance app → taps Wallet → WalletConnect → Scan. They scan the QR code on-screen. Binance is fully WalletConnect v2 compatible across all supported chains. No credentials or private keys are ever shared — the link is peer-to-peer only.

Once paired, the exact contract amount, your receiving wallet address, and the selected network are pushed as a pending transaction request directly into the client's Binance wallet. The client sees the full breakdown — amount, address, network fee — before authorizing.

The client confirms on their own device. Binance broadcasts the signed transaction to the blockchain. No intermediary touches the funds — settlement goes directly on-chain from client wallet to your contract wallet address.

Blockchain confirms the transaction (typically 10–60 seconds depending on network). A transaction hash (TxHash) is returned — your immutable, on-chain proof of payment permanently linked to this VaultSign contract invoice.
