Frequently asked questions about blockchain ROSCAs, tandas, and pasanakus on KhipuVault.

Rotating Pool FAQ

Common questions about participating in and organizing rotating savings pools on KhipuVault.

General Questions

What's the difference between a tanda, pasanaku, and ROSCA?

They're all the same concept - rotating savings circles - just with different cultural names:

ROSCA - Global term (Rotating Savings and Credit Association)
Tanda - Mexico, Central America
Pasanaku - Bolivia, Peru (Quechua/Aymara origin)
Cundina - Peru, Ecuador
San - Colombia

KhipuVault supports all these traditions on blockchain with the same smart contract system.

How is a rotating pool different from other KhipuVault products?

Feature	Rotating Pool	Individual Savings	Community Pool
Participants	3-50 members	Just you	2+ members
Withdrawals	Only on your turn	Anytime	Anytime (with rules)
Goal	Lump sum distribution	Flexible savings	Shared savings
Commitment	Fixed duration	None	Varies
Best for	Planned expenses	Emergency fund	Group goals

Is this legal?

Yes. Rotating savings circles are legal worldwide and have existed for centuries. KhipuVault simply brings them on-chain with smart contracts.

However, crypto regulations vary by country. Ensure you comply with your local laws regarding:

Cryptocurrency ownership
Tax reporting on yields
Cross-border transfers (if international pool)

Always consult a local tax professional.

Why use blockchain instead of traditional ROSCAs?

Blockchain advantages:

✅ Transparent records (no disputes)
✅ Automatic payments (no manual collection)
✅ Smart contract enforcement (reduced defaults)
✅ Global participation (connect diaspora communities)
✅ Verifiable history (build reputation)

Traditional advantages:

✅ No technology barriers
✅ Cash-based (no crypto needed)
✅ Personal relationships
✅ Cultural familiarity

KhipuVault combines the best of both: blockchain infrastructure with cultural tradition.

What if I don't trust blockchain technology?

Valid concern! Here's what protects you:

Audited contracts - Security experts verify our code
Open source - Anyone can inspect the contracts
On-chain verification - Every transaction is public
No custody - You control your wallet, not KhipuVault
Tested extensively - Months of testing on Mezo testnet

Start small: Join a low-value pool first to build confidence.

Joining & Membership

How do I find pools to join?

Three ways:

Direct invitation - Organizer shares pool link
Browse public pools - KhipuVault marketplace
Create your own - Start a pool and invite members

We recommend joining pools with people you know or who have high reputation scores.

What do I need to join?

Required:

MUSD balance (for contributions + collateral)
Compatible wallet (MetaMask, Coinbase Wallet, etc.)
Mezo testnet access

Recommended:

Email for notifications
Stable income to support contributions
Understanding of commitment duration

Can I join multiple pools at once?

Yes! Many users participate in several pools simultaneously:

Example:

Pool A: $50/week, 8 members, your turn Round 3
Pool B: $100/month, 10 members, your turn Round 7
Pool C: $200/biweekly, 6 members, your turn Round 2

Just ensure you can afford all commitments:

Monthly total:
Pool A: ~$200/month
Pool B: $100/month
Pool C: ~$400/month
───────────────
Total: $700/month commitment

Can I leave a pool after joining?

Before pool starts: Yes, easy exit with collateral refund.

After pool starts: Only via emergency exit:

Requires organizer/member approval
10% penalty on your equity
Damages your reputation score
Should only be done for true emergencies

After receiving payout: You MUST complete all remaining contributions. No exit allowed.

What happens if the pool doesn't fill up?

Organizers set a minimum member threshold (usually 3-5). If not met by start date:

Option 1: Extended recruitment

Original start: Feb 1
Extended deadline: Feb 15
Minimum members: 5

Option 2: Start with fewer members

Planned: 10 members × $100 = $1,000 pot
Actual: 7 members × $100 = $700 pot
Rotation: 7 rounds instead of 10

Option 3: Cancel and refund

Status: DISSOLVED
All collateral: Refunded
Pool: Cancelled, try again

Contributions & Payments

How do automatic payments work?

Setup (one-time):

Approve MUSD spending by pool contract
Keep sufficient MUSD balance in wallet
Contract pulls exact amount on schedule

Each round:

Due date arrives → Smart contract executes → Pulls from all members → Distributes to recipient

No manual action needed unless you run out of MUSD.

What if I forget to pay?

The smart contract attempts automatic pull. If it fails (insufficient balance):

Grace period (typically 3 days):

No penalty yet
Reminders sent
Time to add funds

After grace period:

Late penalties apply (e.g., 5% per week)
Your reputation score drops
Risk of default if too late

Avoid this:

Set calendar reminders
Keep buffer MUSD balance
Enable email/SMS notifications

Can I pay early or skip a round?

Pay early: No. Smart contract pulls on fixed schedule.

Pay extra: Yes, but doesn't skip future rounds.

Skip a round: No. Every round requires full participation.

The design is intentional: Ensures fairness and predictability for all members.

What happens if someone else doesn't pay?

During grace period:

Pool waits for late member
Payout delayed until payment received
Other members notified

After default:

Member's collateral slashed to cover contribution
Slashed funds distributed to current round recipient
Defaulting member expelled
Pool continues with remaining members

If no collateral:

Pool enters emergency state
Members vote on resolution:
- Continue without defaulter (smaller pots)
- Dissolve and refund remaining equity
- Organizer covers shortage

Can I change my contribution amount mid-cycle?

No. All parameters are locked when the pool starts:

Contribution amount
Schedule
Member count
Rotation order

Why? Changing mid-cycle would be unfair to members who already received or planned based on original terms.

Alternative: Complete current cycle, then create new pool with different parameters.

Rotation & Payouts

How is rotation order decided?

Four common methods:

1. First-come, first-served (default)

Join order 1 → Receive Round 1
Join order 2 → Receive Round 2
...

2. Random lottery

All members assigned randomly on-chain at start
Fair for everyone

3. Manual assignment

Organizer sets order based on:
- Member needs (wedding dates, etc.)
- Consensus discussion
- Community decision

4. Bidding (advanced)

Each round, members bid discount to receive early
Highest bidder wins that round

Can I swap my position with another member?

Yes, if both parties agree and organizer approves:

Propose Swap

You: Round 9 → Want Round 4
Other member: Round 4 → Willing to move to Round 9

Order Updated

NEW rotation order:
Round 4: YOU (swapped)
Round 9: Other member (swapped)

Why swap?

Urgent need for earlier payout
Preference for later position (higher yields)
Accommodate life events

When exactly do I receive my payout?

Scheduled time:

Round 9: November 1, 2026, 12:00 PM UTC

Actual distribution:

Automatic pools: Within minutes of scheduled time
Manual claim pools: After all contributions verified

Delays possible if:

Members late on payments (during grace period)
Technical issues (rare)
Organizer manually reviewing (high-value pools)

Check dashboard for real-time status.

What if I don't receive my payout?

First, check:

Pool status - Is round complete?
Payment status - Did all members pay?
Wallet - Is it connected and accessible?
Transaction history - Was it sent?

Then:

If sent but not showing:
→ Check Mezo blockchain explorer
→ Verify wallet address
→ Contact wallet support

If not sent:
→ Review payment status of all members
→ Contact pool organizer
→ Check for manual claim button
→ Escalate to KhipuVault support if needed

How are yields calculated on payouts?

Yield source: Contributions deposited in pool earn yields on Mezo before distribution.

Calculation:

Base pot: 1,000 MUSD (10 members × 100)
Holding period: ~7 days average
Current APY: 12%
Weekly rate: 12% / 52 = 0.23%

Gross yields: 1,000 × 0.23% = 2.30 MUSD
Platform fee: 2.30 × 10% = 0.23 MUSD
Net yields: 2.07 MUSD

Total payout: 1,000 + 2.07 = 1,002.07 MUSD

Factors:

Position (later = more yield time)
Market APY (varies 10-18%)
Pool size (larger = more absolute yield)
Holding period (weekly vs monthly pools)

✅ Audited contracts - Third-party security firms review code ✅ Open source - Public verification by community ✅ Battle-tested - Months of testnet usage ✅ Mezo security - Built on secure Bitcoin-backed blockchain ✅ No admin keys - No one can drain funds ✅ Time-locks - Protection against exploit attempts

Risks remain:

Smart contract bugs (mitigated by audits)
Blockchain vulnerabilities (very rare on Mezo)
Your wallet security (protect seed phrase!)

Best practices:

Start with small amounts
Verify contract addresses
Use hardware wallet for large sums
Never share seed phrase

What if the organizer is malicious?

Organizer powers are LIMITED:

Can do:

Set pool parameters at creation
Approve emergency exits
Send announcements
Pause in extreme emergency

Cannot do:

❌ Withdraw funds
❌ Change rotation order mid-cycle
❌ Steal collateral
❌ Skip distributions
❌ Modify contributions

Smart contract enforces all critical operations. Organizer is more like a coordinator than a controller.

For high-value pools:

Use multi-signature organizers (3 of 5 approval)
Check organizer reputation score
Require transparent communication
Verify contract source code

What happens if KhipuVault shuts down?

Your funds are safe because:

Smart contracts are autonomous - They run on blockchain regardless of KhipuVault website
You control your wallet - Not custodial
Open source - Anyone can build alternative frontend
On-chain data - All records permanent

How to access:

If app.khipuvault.com goes offline:
→ Use blockchain explorer (Mezo block explorer)
→ Interact directly with contract
→ Community can fork frontend
→ Your wallet still works

Recommendation: Save your pool contract address.

Can the government seize my pool funds?

Technical answer: Funds are in a smart contract, not a bank account. Harder to seize.

Legal answer: Depends on your jurisdiction. Governments can:

Require reporting of crypto holdings
Tax yields as income
Seize crypto in some cases (varies widely)

Compliance is your responsibility:

Report yields on taxes if required
Follow local crypto regulations
Consult legal expert if concerned

KhipuVault is not a bank and doesn't hold your funds. We provide software tools.

Fees & Costs

What fees does KhipuVault charge?

Platform fee: 10% of yields only

Examples:

Example 1: Individual Savings
Deposit: 1,000 MUSD

Contribution: $0 (automatic pull)
Claim payout: $0 (automatic) or ~$0.10 (manual)

Gas fees go to Mezo validators, not KhipuVault.

Testnet note: Currently using test funds. Mainnet fees may vary.

Are there any hidden costs?

No hidden fees. All costs transparent:

Upfront costs:

Collateral (refundable, not a fee)
Initial gas for joining

Ongoing costs:

Contributions (go into pot, not a fee)
Platform fee (10% of yields only)

Technical Questions

What blockchain is this on?

Mezo Blockchain:

Chain ID: 31611 (testnet)
Bitcoin-backed security
EVM-compatible (like Ethereum)
Fast, low-cost transactions

Why Mezo?

Bitcoin security without Bitcoin fees
DeFi yields on BTC
Built for savings applications
Latin America friendly

What is MUSD?

MUSD = Mezo USD, the stablecoin on Mezo blockchain.

Pegged to US Dollar (1 MUSD ≈ $1 USD)
Used for all KhipuVault transactions
Backed by Bitcoin collateral on Mezo
Can be swapped for other stablecoins

Get MUSD:

Bridge from Ethereum/other chains
Swap from other Mezo tokens
Buy from supported exchanges

Do I need to keep my wallet connected all the time?

No. Your wallet only needs to be connected when:

For automatic payments:

Doesn't need to be online
Smart contract pulls from your address
Works even if computer is off

For manual actions:

Creating a pool
Joining a pool
Manual claiming payout
Emergency exits

Between these actions, you can disconnect safely.

Can I use a hardware wallet?

Yes! Highly recommended for large amounts:

Compatible wallets:

Ledger (via MetaMask)
Trezor (via MetaMask)
GridPlus Lattice

Benefits:

Offline private key storage
Extra security layer
Protection from malware

Considerations:

Must connect to approve each transaction
Slight UX friction (worth it for security)

What if I lose access to my wallet?

Prevention (CRITICAL):

Write down seed phrase on paper
Store in safe, secure location
NEVER digital copy (no photos, no cloud)
Consider metal backup for fire protection
Test recovery process

If lost without backup:

❌ Funds are unrecoverable
❌ Cannot access pool payouts
❌ No customer service can help

This is blockchain: You are your own bank. Backup is YOUR responsibility.

Pool implications: If you lose wallet access during pool:

Can't receive payout (unless you recover)
Organizer CANNOT reroute to new address (security feature)
You'll miss your turn

Can I participate from outside the US?

Yes! KhipuVault is global.

Requirements:

Internet access
Compatible wallet
MUSD tokens
Compliance with your local laws

Popular regions:

Latin America (Mexico, Peru, Bolivia, Colombia)
United States
Europe
Asia

Remittance use case: Many users create pools with family across borders. Example: Workers in US + family in Mexico in same tanda.

How do I organize a pool with my family?

Step-by-step:

Gauge interest - Ask family members if interested

Determine parameters

8 family members
$50/month each
$400 pot per round
8 months duration

Help with wallets - Assist less tech-savvy members
Create pool - Set 0-25% collateral (trust-based)
Onboard members - Walk through joining process
Stay connected - Family chat for updates

Cultural tip: Use traditional names (tanda/pasanaku) to honor heritage.

Can non-technical people participate?

Yes, but requires learning:

Skills needed:

Install wallet app (15 min tutorial)
Buy/receive MUSD (one-time setup)
Connect wallet to KhipuVault (simple)
Monitor notifications (email/SMS)

KhipuVault makes it easier:

Step-by-step wizards
Video tutorials (in Spanish & English)
Customer support
Simple interface

Organizer role:

Help members set up wallets
Provide ongoing support
Explain blockchain basics
Troubleshoot issues

Reality: First pool has learning curve. Second pool is easy.

How do traditional ROSCA participants react to blockchain?

Common concerns:

"Why change what works?" → We enhance, not replace. Keep the community spirit, add transparency.

"I don't understand technology." → You don't need to understand blockchain internals. Just use the app like online banking.

"I prefer cash." → MUSD is digital cash. Stable value, works globally.

"What about people without internet?" → Blockchain ROSCAs are for connected communities. Traditional ROSCAs still valuable for offline groups.

Success stories:

Immigrants staying connected with home communities
Young generation introducing elders to crypto savings
Remote workers organizing global tandas

Can I run a pool for my workplace?

Yes! Common use case:

Workplace tanda example:

15 coworkers
$100 biweekly (payday aligned)
$1,500 pot
Rotation matches annual timing
  - January → Tax season expenses
  - July → Summer vacation
  - December → Holiday shopping

Advantages:

See members daily (trust)
Aligned payday schedule
Shared culture/community
Easy communication

Considerations:

Company policy on workplace pools
Avoid pressure on coworkers
Handle departures (emergency exit)

Is this culturally appropriate?

KhipuVault respects tradition:

✅ Honors centuries-old practices ✅ Uses cultural names (tanda, pasanaku) ✅ Preserves community spirit ✅ Serves underbanked populations ✅ Enables diaspora connections

We add value without appropriation:

Built by people from ROSCA cultures
Designed for financial inclusion
Open to all, not extractive
Community-focused, not profit-maximizing

Feedback welcome: We improve based on community input.

Troubleshooting

"Insufficient balance" error when joining

Cause: Not enough MUSD for collateral + first contribution.

Solution:

Required: Collateral (500) + Contribution (100) = 600 MUSD
Your balance: Check wallet
Need to: Buy/bridge more MUSD

"Approval required" error

Cause: Haven't approved pool contract to spend your MUSD.

Solution:

Click "Approve MUSD"
Sign transaction (small gas fee)
Wait for confirmation
Then join pool

Can't see my pool on the dashboard

Possible causes:

Wrong network - Switch to Mezo testnet
Wrong wallet - Connect the wallet you joined with
Pool not yet created - Check transaction status
Browser cache - Hard refresh (Ctrl+Shift+R)

Solution:

1. Verify network: Mezo (31611)
2. Verify wallet address matches
3. Search by pool address: 0x7a8E...
4. Contact support if still missing

Payment didn't go through

Check:

MUSD balance - Enough for contribution?
Approval - Still active?
Gas - Enough ETH for transaction?
Due date - Is it actually due yet?

Retry:

Dashboard → Your Pool → "Pay Now" button → Sign transaction

Payout is less than expected

Common reasons:

Late payment penalties applied to you
Market yields lower than estimated
Another member defaulted (pool size reduced)

Verify:

View payout breakdown:
- Base pot: Expected amount
- Yields: Actual earned
- Penalties: Any deductions
- Fees: Platform fee on yields

Advanced Topics

Can I create private pools?

Yes:

Privacy Settings:
- Unlisted: Not shown in public marketplace
- Invite-only: Requires approval to join
- Private metadata: Only members see details

Still on-chain: Transactions are public, but pool is not advertised.

Use case: Family pools, close friend groups, exclusive communities.

What about bidding ROSCAs?

Advanced feature for sophisticated groups:

How it works:

Round 1 bidding:
- Member A bids: 5% discount (receive $950 now)
- Member B bids: 8% discount (receive $920 now)
- Member C: No bid

Winner: Member B (highest discount)
Members A & C: Keep bidding in future rounds

Advantages:

Urgency rewarded
Market-driven order
Flexibility

Disadvantages:

Complexity
Favors wealthy members
Confusing for traditional users

Recommendation: Stick with fixed-order for cultural authenticity.

Can I integrate pools with other DeFi?

Current: KhipuVault pools are standalone.

Future possibilities:

Collateral from other protocols (e.g., deposit Aave tokens)
Payouts auto-swap to other assets
Yield from multiple sources
Cross-chain pools

Developers: Open to integrations. Contact us.

What's the maximum pool size?

Technical limit: 50 members (gas efficiency)

Practical limit: 15-20 members

Why?

Coordination difficulty
Default risk increases

Cycle becomes very long

50 members × 30 days = 50 months (4+ years!)

Better approach: Multiple smaller pools or split into cohorts.

Can I create pools with other assets besides MUSD?

Currently: MUSD only.

Planned:

BTC-backed pools
ETH pools
Multi-asset options

Why start with MUSD?

Stable value (no price volatility risk)
Easy yield generation
Simple accounting
Familiar (dollar-denominated)
