VestRoll: Payroll

VestRoll is a payroll and invoicing platform built for the 2026 financial ecosystem. Built with Next.js 15, React 19, and the Stellar Soroban stack, it offers a "No-Crypto" UX where privacy, speed, and biometric security are standard.

🏗️ The 2026 Technology Stack

Core Architecture

• Framework: Next.js 15.5 (App Router & Turbopack)
• Library: React 19
• State: Redux Toolkit (UI) & Zustand (Store)

Identity & Privacy (ZK)

• Auth: @stellar/passkey-kit (FaceID/TouchID Biometric Login)
• Privacy: Stellar Protocol 25 (X-Ray) & circomlib for ZK-shielded payroll.
• Smart Accounts: @stellar/smart-account-kit for automated contract-wallet deployment.

Finance & Fiat Bridge

• Fiat Providers: Native integration for Monnify and Flutterwave (NGN On-ramps).
• Stellar Bridge: SEP-24 via Stellar Wallet SDK for automated NGN-to-USDC settlement.
• Gasless UX: Launchtube / Fee-Bumping infrastructure (Zero XLM required for users).

✨ Key Features

• Invisible Onboarding: Users sign up with Email and Biometrics (Passkeys). No seed phrases, no private keys, no 12-word recovery.
• Hybrid Recovery: A "Best of Both Worlds" security model—Biometric speed for daily use, Email recovery for account resets.
• ZK-Shielded Payments: Payroll amounts are hidden from the public ledger using Zero-Knowledge proofs, providing enterprise-grade confidentiality.
• Automated Fiat-Stable Bridge: Deposits in Naira (NGN) are automatically reflected as USDC in the Smart Wallet, enabling instant global payouts.
• Atomic Batching: Disburse 100+ payroll entries in a single biometric signature using Soroban atomic transactions.
• Invisible Gas: Transaction fees are sponsored (Launchtube) or paid in USDC, ensuring users never need to hold or know about XLM.
