How to Redeem DAI/USDS and Retrieve Collateral Through MakerDAO/Sky Protocol

Learn how to redeem DAI/USDS stablecoins and retrieve collateral using MakerDAO and Sky protocol, understanding the complete redemption process and risk management.

What is MakerDAO/Sky Protocol Redemption?

MakerDAO and Sky protocol redemption refers to the process of repaying generated DAI/USDS stablecoins to the protocol to retrieve previously deposited collateral (e.g., ETH, WBTC, etc.). After redemption, you can close the vault or keep it open.

Pre-redemption Preparation

1. Check Position Status

Information to Confirm:

  • Health Factor: Ensure sufficiently high (recommend 1.5+), avoid triggering liquidation after redemption
  • Current Collateral Ratio: Ensure sufficiently high, avoid triggering liquidation after redemption
  • Outstanding Debt: Amount of DAI/USDS to repay
  • Available Collateral: Amount of collateral that can be withdrawn
  • Stability Fee: Accumulated stability fees to pay (if any)

How to View in Spark.fi:

  • Access "My Portfolio" page
  • View outstanding debt in "Borrow" section
  • View available collateral in "Supply" section
  • View health factor and liquidation price

2. Prepare Stablecoins

Need to Prepare:

  • Sufficient DAI/USDS for debt repayment
  • Additional stablecoins for stability fees (if any)
  • Sufficient ETH to pay Gas fees

3. Choose Redemption Strategy

Full Redemption:

  • Repay all DAI/USDS debt
  • Withdraw all collateral
  • Close position
  • Suitable when no longer need stablecoins

Partial Redemption:

  • Only repay part of DAI/USDS
  • Withdraw part of collateral
  • Keep position open
  • Suitable when need partial liquidity

Redemption Process

Managing Positions

Monitor Health Factor and Collateral Ratio

Why It's Important:

  • Health Factor or collateral ratio may decrease after redemption
  • Need to ensure safety margin is maintained after redemption
  • Avoid triggering liquidation

How to Monitor:

  1. View in Spark.fi:

    • Access "My Portfolio" page
    • View Health Factor
    • Check collateral ratio and liquidation price
    • Use health factor monitoring tools provided by protocol
  2. Use Third-party Tools:

    • DeFiPulse
    • Zapper
    • DeBank
    • Other DeFi monitoring tools
  3. Set Price Alerts:

    • Use price alert tools
    • Notify promptly when collateral price drops
    • Adjust collateral ratio or health factor promptly

Partial Redemption Strategies

Strategy 1: Only Repay Stablecoins

  • Repay partial DAI/USDS
  • Don't withdraw collateral
  • Result: Collateral ratio increases, safer

Strategy 2: Only Withdraw Collateral

  • Don't repay DAI/USDS
  • Withdraw partial collateral
  • Result: Collateral ratio decreases, risk increases (not recommended)

Strategy 3: Balanced Redemption

  • Repay partial DAI/USDS
  • Withdraw partial collateral
  • Result: Maintain stable collateral ratio

Recommended Strategy:

  • Prioritize repaying stablecoins to increase health factor and collateral ratio
  • Withdraw collateral only when health factor is sufficiently high (recommend 1.5+)
  • Maintain health factor above 1.5 (equivalent to 150% collateral ratio)

Fee Explanation

Stability Fee

What is Stability Fee:

  • Annual rate, adjusted based on market
  • Usually 1-5%
  • Accumulates in debt

How to Pay:

  • Stability fee accumulates in debt
  • Need to pay together when repaying DAI/USDS
  • Or cover stability fee by adding collateral

Fee Examples:

  • Debt: 10,000 DAI
  • Stability fee rate: 2%
  • Holding time: 1 year
  • Stability fee: Approximately 200 DAI

Gas Fees

Gas Fee Explanation:

  • Gas fees required for each operation
  • Fluctuates based on network congestion
  • Usually $10-50 per operation (normal conditions)
  • May be $50-200+ during network congestion

Redemption Operations:

  • Repay stablecoins: 1 transaction
  • Withdraw collateral: 1 transaction
  • Full redemption: 2 transactions
  • Total Gas fees: Approximately $20-100 (normal conditions)

No Redemption Fees

MakerDAO/Sky Protocol:

  • No Redemption Fees: No additional redemption fees charged
  • Only Gas: Only need to pay Gas fees
  • Transparent Fees: All fees transparent and visible

Risk Management

1. Liquidation Risk

Risk Sources:

  • Health Factor or collateral ratio may decrease after redemption
  • Market volatility may cause insufficient health factor
  • Need to ensure safety margin is maintained after redemption

Mitigation Strategies:

  • Check health factor and collateral ratio before redemption
  • Don't withdraw too much collateral
  • Maintain health factor above 1.5 (equivalent to 150% collateral ratio)
  • Be cautious during high market volatility
  • Use health factor monitoring tools provided by protocol

2. Stability Fee Risk

Risk Sources:

  • Stability fees continue to accumulate
  • High costs for long-term holding
  • Need to pay together when redeeming

Mitigation Strategies:

  • Understand stability fee rates
  • Calculate total costs
  • Consider holding time
  • Redeem promptly to reduce fees

3. Gas Fee Risk

Risk Sources:

  • Network congestion causes high Gas
  • Need multiple transactions (repay + withdraw)
  • Gas may be high during urgent redemption

Mitigation Strategies:

  • Choose times when network is less congested
  • Use Gas optimization tools
  • Reserve sufficient ETH to pay Gas
  • Consider batch operations

Best Practices

  1. Plan Redemption Timing

    • Choose stable market times for redemption
    • Avoid operations during high market volatility
    • Consider Gas fee costs
  2. Maintain Safety Margin

    • Maintain sufficient health factor after redemption (recommend 1.5+, equivalent to 150% collateral ratio)
    • Don't withdraw too much collateral
    • Reserve buffer space
    • Use health factor monitoring tools provided by protocol
  3. Batch Redemption

    • Recommend batch processing for large redemptions
    • Reduce price impact
    • Reduce single transaction risk
  4. Monitor Fees

    • Understand all related fees
    • Calculate total costs
    • Ensure redemption is economically reasonable
  5. Test Small Amount Redemption

    • Recommend small amount testing for first redemption
    • Familiarize with process before large operations
    • Verify all steps are normal

Frequently Asked Questions

Q: Can I only withdraw collateral without repaying stablecoins?

A: Not recommended in most cases. If you only withdraw collateral without repaying stablecoins, Health Factor and collateral ratio will decrease and may trigger liquidation. Recommend repaying stablecoins first, then withdraw collateral after health factor and collateral ratio increase.

Q: How long does redemption take?

A: Usually takes minutes to tens of minutes, depending on network congestion and Gas fee settings. Repayment and withdrawal each require one on-chain confirmation.

Q: What are the redemption fees?

A: MakerDAO/Sky protocol does not charge redemption fees, only need to pay Gas fees. But need to pay accumulated stability fees (if any).

Q: Is redemption cost-effective if collateral price rises?

A: This depends on your goals:

  • If goal is to take profits, redemption is reasonable
  • If goal is to continue holding stablecoins, may not need redemption
  • Consider opportunity costs and fees

Q: Can I mint again after redemption?

A: Yes, you can mint again at any time. However, note:

  • Need to pay minting fees again
  • Need to pay Gas fees
  • Market conditions may have changed

Q: Will partial redemption affect health factor or collateral ratio?

A: Yes, partial redemption will change Health Factor and collateral ratio:

  • If only repay stablecoins without withdrawing collateral: Health Factor and collateral ratio increase
  • If only withdraw collateral without repaying stablecoins: Health Factor and collateral ratio decrease (may trigger liquidation)
  • Need balanced operations to maintain safety margin (recommend maintaining health factor above 1.5)

Q: What is Health Factor?

A: Health Factor is an indicator used by Spark.fi to measure position safety:

  • Health Factor = 1.0: Reached liquidation threshold
  • Health Factor < 1.0: May be liquidated
  • Health Factor > 1.5: Relatively safe (equivalent to 150% collateral ratio)
  • Health Factor > 2.0: Very safe (equivalent to 200% collateral ratio)

Recommend maintaining health factor above 1.5 to ensure safety.
