Risks

Risk Management

Understanding and managing risk is crucial when using DeFi protocols. This page outlines the risks involved with Zentra and the measures in place to mitigate them.

Risk Categories

Risk Type	Description
Smart Contract Risk	Code bugs, exploits
Market Risk	Price drops, volatility
Liquidation Risk	Position closed at loss
Oracle Risk	Price feed manipulation
Liquidity Risk	Unable to withdraw
Governance Risk	Malicious proposals

Smart Contract Risk

What Is It?

Smart contracts may contain bugs or vulnerabilities that could result in loss of funds.

Mitigation Measures

Measure	Description
Audits	Professional security firms review code
Battle-tested	Based on Aave's proven architecture
Bug bounty	Rewards for responsible disclosure
Formal verification	Mathematical proofs of correctness
Timelocks	Delays on contract upgrades

User Protection

Action	Benefit
Start small	Test with amounts you can afford to lose
Monitor audits	Check audit reports before depositing
Diversify	Don't put all funds in one protocol

Market Risk

What Is It?

Asset prices can decline, affecting collateral values and potentially causing liquidations.

Volatility Impact

Example: BTC drops 20% overnight

Metric	Before	After
Collateral	1 wcBTC = $50,000	1 wcBTC = $40,000
Borrowed	$30,000 USDC	$30,000 USDC
Health Factor	1.33 ✓	1.07 ⚠️

Mitigation Measures

Measure	Description
Conservative LTV	Collateral factors leave safety buffer
Over-collateralization	Always borrow less than deposit
Multiple collateral types	Diversification reduces single-asset risk

User Protection

Action	Benefit
Don't max out	Keep Health Factor above 2.0
Set alerts	Monitor position, act before liquidation
Hedge	Consider hedging strategies

Liquidation Risk

What Is It?

If your Health Factor drops below 1.0, your position can be liquidated at a loss.

Liquidation Impact Example

Before Liquidation:

• Collateral: 1 wcBTC ($40,000)

• Debt: $35,000 USDC

• Health Factor: 0.91 (liquidatable)

Liquidation (50% of debt):

• Debt repaid: $17,500

• Collateral taken: $19,250 (includes 10% penalty)

After Liquidation:

• Collateral: $20,750 worth of wcBTC

• Debt: $17,500 USDC

• Loss: $1,750 (liquidation penalty)

Mitigation Measures

Measure	Description
Partial liquidations	Only 50% closed per transaction
Gradual penalties	Lower penalty for less volatile assets
Warning zone	Dashboard alerts as HF approaches 1.0

User Protection

Action	Benefit
Monitor daily	Track Health Factor regularly
Maintain buffer	Keep HF > 1.5 at minimum
Prepare capital	Have funds ready to add collateral
Set stop-loss	Define when you'll add collateral

Oracle Risk

What Is It?

Oracles provide price data. If manipulated or incorrect, it could enable exploits or wrongful liquidations.

Potential Issues

Issue	Impact
Price manipulation	Artificial liquidations or borrowing
Stale prices	Incorrect valuations
Oracle downtime	Protocol pause

Mitigation Measures

Measure	Description
Multi-source	Aggregate multiple price feeds
TWAP	Time-weighted prices resist flash attacks
Circuit breakers	Pause on extreme price moves
Fallback oracles	Backup price sources

Liquidity Risk

What Is It?

If utilization is very high, you may not be able to withdraw your supplied assets immediately.

How It Happens

Example:

• Total Supplied: $10,000,000 USDC

• Total Borrowed: $9,500,000 USDC

• Available: $500,000 USDC

• Utilization: 95%

If you want to withdraw $1,000,000:

• Only $500,000 available

• Must wait for repayments or utilization to drop

Mitigation Measures

Measure	Description
Interest rate model	High utilization = higher borrow rates
Rate incentives	Discourages excessive borrowing
Reserve buffer	Protocol maintains some liquidity

User Protection

Action	Benefit
Check utilization	Before large deposits
Monitor liquidity	Especially before planned withdrawals
Partial withdrawals	Withdraw in smaller amounts

Governance Risk

What Is It?

Governance controls protocol parameters. Malicious or poorly-considered proposals could harm users.

Potential Issues

Issue	Impact
Malicious proposal	Parameter changes that benefit attackers
Poor decisions	Suboptimal changes affecting users
Voter apathy	Low participation enables bad proposals

Mitigation Measures

Measure	Description
Timelocks	Delay between vote and execution
Quorum requirements	Minimum participation to pass
Guardian multisig	Emergency pause capability
Transparent process	Public discussion before votes

Systemic Risk

What Is It?

Risks affecting the entire DeFi ecosystem or underlying blockchain.

Examples

Risk	Description
Chain halt	Citrea network stops producing blocks
Bridge exploit	wcBTC bridge compromised
Contagion	Failure of other protocols impacts Zentra
Regulatory	Legal changes affecting DeFi

Mitigation Measures

Measure	Description
Native focus	Built specifically for Citrea
Conservative assets	Launch with proven assets only
Isolation	Minimal dependencies on other protocols

Risk Parameters by Asset

Parameter	USDC	wcBTC	ctUSD
Collateral Factor	85%	70%	80%
Reserve Factor	130%	20%	13%

Why Different Parameters?

Asset	Risk Level	Rationale
USDC,ctUSD	Lower	Stable price, low volatility
wcBTC	Higher	Volatile

Risk Checklist

Before using Zentra:

• ✅ Understand smart contract risk (audit status, battle-testing)

• ✅ Accept market risk (potential for asset price decline)

• ✅ Know liquidation rules (HF threshold, penalty)

• ✅ Check current utilization (liquidity availability)

• ✅ Review risk parameters (collateral factors, thresholds)

• ✅ Only deposit what you can afford to lose
