🏗 How it Works

Rhythm uses a "Set & Forget" model for wealth management:

1. Define Rules: Set your desired percentages for Savings and Bills (e.g., 50% Savings, 30% Bills, 20% Spend).
2. Deposit (Top-Up): Add FLOW tokens to your Treasury.
3. Automated Split: Our execution engine automatically splits and allocates your funds to the correct on-chain vaults.
4. Track Wealth: Monitor your growing balances and transaction history in real-time.
