Snitch

Snitch is a SaaS platform that provides businesses with a secure stablecoin wallet infrastructure for managing on chain financial operations. Built on Solana, the platform enables companies to handle payments, payroll, vendor payouts, and treasury management through shared wallets with role based permissions and team access controls. Snitch streamlines stablecoin native finance workflows by giving organizations a centralized and collaborative system to manage stablecoin transactions efficiently at scale.

The platform also integrates confidential settlement capabilities through Umbra on Solana to provide private checkout and payout infrastructure for businesses handling stablecoin transactions. This enables companies to process confidential payments while preserving the speed, transparency, and efficiency of blockchain based finance. Designed for startups, DAOs, and internet-native companies, Snitch combines enterprise grade controls with blockchain-native payment workflows to deliver a modern financial operations stack for the digital economy.

• Create Solana stablecoin invoices with customer, memo, due date, amount, terms, and treasury metadata.
• Generate hosted checkout pages that customers can open from a payment link.
• Let customers connect a Solana wallet and complete confidential invoice payments.
• Route confidential payment flows through Umbra privacy infrastructure.
• Track payment status, receipts, transaction signatures, and reconciliation context.
• Explain confidential payments through a dedicated Umbra transaction explorer page.
• Create treasury payouts to receiver wallets with memo, approval policy, and compliance checks.
• Support admin-style team access controls for finance, support, analyst, and developer roles.
• Provide a merchant dashboard for payment history, balances, payout operations, and activity review.

Public blockchains are transparent by default. That is useful for verification, but it creates a problem for businesses: every payment can reveal customer relationships, treasury wallets, payout patterns, and sensitive financial metadata.

Snitch explores a business-grade payment layer where merchants can still accept and reconcile Solana stablecoin payments while protecting sensitive payment relationships. The product goal is to make crypto payments feel closer to modern financial operations: private where needed, auditable where required, and simple enough for teams to use.

Snitch emphasizes confidential on-chain payments using Umbra. In a standard Solana transfer, a block explorer can often show the payer wallet, recipient wallet, amount, and transaction history. In Snitch's confidential checkout flow, the customer signs a payment through Umbra, and the merchant receives a receiver-claimable private payment state instead of a plain customer-to-treasury transfer row.

The app's confidential transaction page explains the flow:

1. The customer signs the payment from their Solana wallet.
2. Umbra creates a private receiver-claimable payment note.
3. A public explorer can see an Umbra program interaction, but not the direct business relationship behind the invoice.
4. Snitch records the proof/signature and marks the invoice as paid for merchant reconciliation.

This is a demo/prototype application. Some invoice and encryption metadata is represented as demo state, and the app includes explicit test-data disclaimers in the API response layer. Configure real treasury wallets, supported mints, RPC endpoints, recipient registration, and operational controls before using any payment flow beyond a demo environment.

Snitch is built for businesses that want Solana stablecoin payments without exposing every payment relationship publicly. A merchant can create an invoice, enable confidential payments, send a hosted checkout link, and let the customer pay privately through Umbra. After payment, Snitch keeps the merchant-facing records needed for reconciliation, receipts, and audit review while the public chain view avoids a plain customer-wallet-to-merchant-wallet transfer trail.

The broader product vision is private, compliant payment operations for internet-native businesses: stablecoin checkout, treasury controls, confidential payouts, and clear records in one place.
