🔎 How DayPay Works

DayPay is a truly decentralized payment tool that enables secure and anonymous transactions. It runs entirely in your browser and never stores your data on any server. We don't know who you are, and we don't track your payments. Your privacy is guaranteed.

For Sellers

• Enter your wallet address for one of 5 supported networks (Bitcoin, Ethereum, BSC, Solana, Tron).
• Set the product price in fiat (e.g., USD, EUR) and add optional details like invoice number or store name.
• DayPay fetches real-time crypto prices via CoinGecko API and generates a QR code with payment details.
• Coming soon: Convert buyer payments to stablecoins (e.g., USDT) to protect against price volatility, with a small 0.5% fee.

For Buyers

• Scan the seller’s QR code using the DayPay buyer panel.
• Connect your wallet (e.g., MetaMask, Trust Wallet) via WalletConnect in just 4 clicks.
• DayPay automatically configures the correct network if needed, processes your payment, and confirms it on-chain.
• Wallet connection disconnects after 5 minutes or payment completion for enhanced security.
