Data Flows

RendBit is designed to handle secure, seamless data flow across users, wallets, and third-party services. Every interaction, from onboarding to cross-border payments, is captured in the backend with encrypted storage, ensuring both transparency and privacy. Users’ actions trigger events that propagate through Redis caching, RabbitMQ messaging, and Stellar blockchain settlement, maintaining consistency across the platform.

The system also supports continuous synchronization with external services like LINKIO for fiat on-ramps/off-ramps, and Stellar Horizon for blockchain interactions. This ensures that deposits, transfers, and swaps are reflected accurately and in near real-time across the network, whether users are online or offline.

Finally, RendBit provides transaction traceability through unique references, transaction hashes, and notifications. Each step of a user’s interaction, whether creating a wallet, depositing funds, or sending cross-border payments, is securely logged for auditability and compliance without compromising user experience.

New User Registration and Onboarding

A new user can visit RendBit and sign up using email and password, or Google OAuth 2.0. The system validates the input, creates a secure account, and sends confirmation via email. Upon first login, the user receives a guided onboarding walkthrough to familiarize them with the platform’s features and interface.

Users can configure preferences such as default currency and preferred language, ensuring that their dashboard reflects personalized settings. By completing the onboarding process, they gain access to a fully activated account ready for transactions.

The outcome ensures that users are registered, verified, and comfortable navigating the platform, providing a strong foundation for engagement with custodial wallet services and cross-border financial features.

Creating a Custodian Wallet

Registered users are prompted to create a RendBit custodial wallet from their dashboard. The system generates a Stellar-compatible wallet address linked to the user account, with wallet keys stored securely using industry-standard encryption.

Once the wallet is created, users see their wallet address, account status, and available features such as Deposit, Transfer, and View Balance. They also receive a confirmation notification ensuring transparency and confidence in wallet creation.

This deliverable guarantees that each user has a fully functional custodial wallet, enabling secure transactions, blockchain interaction, and access to RendBit’s financial ecosystem.

Performing a Deposit Transaction

Users log into the dashboard and navigate to the Deposit section, selecting either fiat (via LINKIO or any other anchor) or crypto deposits. The system provides unique reference codes and instructions for completing the transaction.

The Stellar anchor integration monitors the payment channel, and upon confirmation, the system credits the user wallet with equivalent stable tokens or XLM. Users receive notifications with the amount, timestamp, and transaction hash.

This process ensures secure and accurate deposits, bridging fiat and crypto while maintaining a simple, intuitive interface for users without blockchain expertise.

Transferring Funds Across Borders

Funded users initiate transfers by entering recipient information, currency, and amount. The system calculates exchange rates, fees, and estimated arrival times, ensuring transparency.

The transfer is executed on the Stellar blockchain. If the recipient is a RendBit user, funds appear in their wallet instantly; if external, funds are sent via the appropriate local anchor or cash-out partner. Both sender and recipient receive confirmation and reference IDs.

This deliverable enables near-instant cross-border payments, reducing friction, ensuring transparency, and leveraging blockchain rails while maintaining a user-friendly interface.
