Stateless Crypto Invoicing.
Zero Database. 100% Cryptographic.
Forget clunky payment databases and hosted invoice leaks. RobinPay encodes the recipient address, exact payment token, decimal precision, amount, and expiry duration into a tamper-proof cryptographic invoice token (inv_...).
The Stateless Invoice Token
How RobinPay securely encodes complete invoice parameters inside the payment link without touching a server database:
1. Base64URL Payload
Encodes merchant wallet, token address, amount, order ID, description, and unix expiry timestamp.
2. Cryptographic Signature
HMAC-SHA256 signature or EIP-712 merchant wallet signature guaranteeing the amount cannot be altered by a payer.
3. Direct On-Chain Settlement
The checkout page decodes the payload in the browser and constructs the exact transaction to your merchant address.
