Introduction
GrowStreams is a real-time money streaming protocol built on Vara Network that enables continuous, per-second token flows between addresses. Unlike traditional payment systems that process transactions in batches — daily, weekly, or monthly — GrowStreams allows tokens to flow continuously at a specified rate.
GrowStreams protocol overview on Vara Network
What is Money Streaming?
Money streaming allows you to send tokens to another address at a specific rate per second. For example, instead of paying someone $1,000 per month, you can stream tokens at approximately $0.0004 per second. The receiver can withdraw their accrued balance at any time.
Key Benefits
- Per-second payments — Get paid continuously, not in batches
- Instant withdrawals — Receivers can claim tokens anytime
- Low transaction costs — 8x cheaper than Ethereum L2 solutions
- Programmable — Automate payroll, subscriptions, grants, and more
- Secure escrow — All funds held in audited vault contracts
Use Cases
- Freelance and gig work payments
- DAO contributor salaries
- Open source bounties
- SaaS subscriptions
- Creator patronage
- Revenue sharing
- Automated payroll
- Grant disbursement

Vault Operations
The TokenVault is an escrow contract that securely holds your GROW tokens. When you create a stream, tokens are allocated from your vault balance.
Understanding the Vault
- Secure token storage with audited contracts
- Automatic allocation for active streams
- Withdraw unallocated tokens anytime
- Emergency pause functionality
- Multi-token support (future)

Vault Balance Categories
Balance Formula
Available = Deposited - Allocated// Deposited: total tokens you've sent to vault
// Allocated: tokens reserved for active streams
// Available: tokens you can withdraw or use for new streams

Section 05
Creating Streams
Understanding Streams
A stream is a continuous, per-second token flow from your address (sender) to another address (receiver).
Active
Tokens Flowing
Continuous per-second token transfer. Receiver accrues balance in real time.
Paused
Flow Stopped
Temporarily halted. Can be resumed. Accrued balance is settled.
Stopped
Permanently Ended
Cannot be restarted. Remaining buffer refunded to vault.
Stream Creation Flow

Flow Rate Reference
| Description | Flow Rate (per second) | Hourly | Daily |
|---|---|---|---|
| Slow drip | 1,000,000,000 | 0.0036 GROW | 0.0864 GROW |
| Moderate | 10,000,000,000 | 0.036 GROW | 0.864 GROW |
| Fast | 100,000,000,000 | 0.36 GROW | 8.64 GROW |
| Very fast | 1,000,000,000,000 | 3.6 GROW | 86.4 GROW |
Flow rate examples and the built-in calculator tool
Key Formulas
Minimum Buffer = Flow Rate × 3,600 seconds (1 hour minimum)Recommended Deposit = Flow Rate × Seconds × 1.2 (20% safety margin)
1 GROW/hour = 1,000,000,000,000 / 3,600 = 277,777,778 per second
1 GROW/day = 1,000,000,000,000 / 86,400 = 11,574,074 per second
Creating Your First Stream

Pausing a Stream
When to Pause
- Temporary work stoppage
- Waiting for milestone verification
- Adjusting payment terms
- Low buffer warning
After Pausing
- Token flow stops immediately
- Accrued balance is settled
- Buffer remains allocated
- Status changes to "Paused"
Adding Deposits
Add more tokens to extend a stream's duration.
Add deposit to an active stream — extend duration and avoid liquidation
Deposit Calculations
New Buffer = Current Buffer + Deposit AmountNew Duration = New Buffer / Flow Rate
Stopping a Stream
Warning — Permanent Action
Stopping is permanent and cannot be undone. Remaining buffer returns to your vault. Receiver can still withdraw accrued balance.
Refund Formula
Refund = Deposited - Total Streamed// Refund goes to your vault as "available" balance

Withdrawal Strategy
- Withdraw daily for regular income
- Withdraw weekly to minimize transactions
- Withdraw anytime you need liquidity

Buffer Health Indicators
Healthy
Buffer > 7 days remaining. Stream is safe.
Warning
Buffer < 7 days, > 1 day. Deposit soon.
Critical
Buffer < 1 day. Deposit immediately.
Depleted
Eligible for liquidation. Add funds.
Buffer Depletion Calculation
Time Remaining = Current Buffer / Flow RateExample:
Buffer: 100 GROW · Flow Rate: 0.001 GROW/second
Time Remaining: 100 / 0.001 = 100,000 seconds ≈ 27.8 hours
Stream Liquidation
When buffer drops too low, streams can be liquidated by anyone on the network.
Liquidation Trigger Logic
CONDITION
Buffer Check
Remaining Buffer < Flow Rate × 3,600
↓
False
Stream Safe
Continue normally
True
Liquidatable
Anyone can liquidate
RESULT
Liquidation Called
Stream auto-paused
↓
SENDER
Add Deposit
Must top up buffer to resume
↓
RESUME
Stream Restarts
No tokens lost
Avoiding Liquidation
Monitor buffer status regularly. Enable low-buffer notifications. Add deposits before buffer depletion. The dashboard shows estimated time until depletion.

Issue
Stream Creation Failed

- Ensure deposit ≥ (flow_rate × 3,600)
- Check vault has available balance
- Verify flow rate is greater than 0
Common error state — insufficient vault balance message
Transaction Errors
