About

Managing digital payments, especially across different wallets or for collaborative projects, often feels overly complicated. That is why we built 21.cash: the simplest, most direct path to accepting USDC right on the Base network. Forget about complex integrations or slow settlement times. We leverage the power of the x402 protocol to bring you instant, on chain settlement, making your financial transactions feel as smooth as sending an email. Whether you are an independent creator looking to invoice international clients, a developer needing to gate access to a premium API endpoint, or a team managing shared revenue streams, 21.cash transforms the friction of crypto payments into pure efficiency. Imagine creating a payment link in seconds, sharing it, and watching the funds settle instantly, securely, and exactly where they need to go, all without needing a traditional bank intermediary.

What truly sets 21.cash apart is its built in intelligence for revenue distribution. This isn't just about collecting money; it is about automating the complex logistics of splitting that money fairly and instantly. If you are collaborating with partners, selling access to exclusive content, or running a decentralized application, you can set up automatic revenue splitting across multiple addresses right from the payment link creation screen. This means no more manual tracking, no more end of month reconciliation headaches, and zero risk of human error in distributing earnings. It is designed to handle the nuances of modern digital commerce, allowing you to focus entirely on building your product or service while the financial plumbing handles itself reliably on the Base blockchain.

We understand that trust and speed are paramount when dealing with digital assets. By focusing exclusively on USDC on Base, 21.cash provides a highly optimized, low cost environment for your transactions. This means your clients experience fast, familiar USDC payments, and you benefit from near immediate finality. It is the perfect tool for anyone ready to move beyond traditional payment rails and embrace the transparency and speed of decentralized finance, all wrapped up in an incredibly user friendly interface that requires no deep technical knowledge to start using today. Welcome to the future of streamlined, automated digital invoicing and revenue sharing.
