Decentralized Stablecoin Minting
Learn how to mint stablecoins through smart contract protocols (such as MakerDAO, Ethena, Liquity)
Overview
Decentralized stablecoins are minted through smart contract protocols, no KYC required, just connect your wallet, with higher decentralization and flexibility. Major protocols include MakerDAO (DAI), Ethena (USDE), Liquity (LUSD), and Frax Finance (FRAX).
Key Features:
- ✅ No KYC: Most protocols don't require identity verification
- ✅ Low Threshold: Small amounts can participate (as low as a few hundred dollars)
- ✅ Simple Process: Just connect wallet
- ✅ Decentralized: Not dependent on a single entity
- ✅ Fast: Instant on-chain processing (completed in minutes)
- ⚠️ Liquidation Risk: Need to maintain collateral ratio, may be liquidated
- ⚠️ Smart Contract Risk: Code vulnerability risks exist
- ⚠️ Gas Fees: Can be very high (during network congestion)
Target Users:
- Users holding ETH, BTC, and other assets
- Users wanting decentralized stablecoins
- Individual and small users
- Users wanting to avoid KYC

Preparation
1. Choose the Right Protocol
Considerations:
- Collateral Ratio Requirements: Different protocols have different requirements (110%-150%+)
- Fee Structure: Stability fees, one-time fees, etc.
- Liquidation Risk: Lower collateral ratio requirements mean higher risk
- Yield Opportunities: Some protocols provide yield (e.g., Ethena)
- Degree of Decentralization: Protocol's level of decentralization
- Collateral Types: Supported collateral types
2. Prepare Collateral
Common Collateral:
- ETH: Most commonly used, good liquidity, supported by most protocols
- BTC: Stable value, but needs to be wrapped (WBTC)
- Stablecoins: Some protocols support (e.g., Ethena accepts USDC/USDT)
- Other Assets: Depending on protocol support (e.g., WBTC, USDC, etc.)
Notes:
- Ensure sufficient collateral
- Consider price volatility risk
- Reserve Gas fees (ETH)
- Understand collateral liquidity
3. Set Collateral Ratio
Recommendations:
- Conservative: 200%+ (low risk, suitable for beginners)
- Balanced: 150-200% (medium risk, suitable for experienced users)
- Aggressive: 110-150% (high risk, not recommended for beginners)
Risk Warnings:
- Low collateral ratio may trigger liquidation
- Market volatility may cause collateral ratio to drop
- Need to regularly monitor collateral ratio
- Recommend setting price alerts
4. Prepare Wallet and Gas
Wallet Preparation:
- Install and set up wallet (MetaMask, WalletConnect, etc.)
- Ensure wallet security (backup seed phrase)
- Prepare sufficient ETH to pay Gas fees
Gas Fees:
- Each operation requires Gas fees
- Gas fees fluctuate based on network congestion
- Recommend operating when network is not congested
- Reserve sufficient ETH (recommend at least 0.1 ETH)

- Withdraw Stablecoins: Withdraw generated stablecoins when needed
- Set Alerts: Use protocol-provided monitoring tools or third-party tools
Risk Management
1. Liquidation Risk
What is Liquidation? When the collateral ratio falls below the protocol's minimum requirement, the protocol will automatically liquidate your collateral to repay stablecoin debt. You may lose part of your collateral as a liquidation penalty.
How to Avoid:
- Maintain sufficient collateral ratio (recommend 150%+)
- Regularly monitor collateral ratio (check at least once daily)
- Set price alerts (using tools like DeFiPulse, Zapper, etc.)
- Adjust promptly during market volatility
- Don't set collateral ratio too low
Liquidation Consequences:
- Lose part of collateral (typically 5-13%)
- Need to pay liquidation penalty
- May lose all collateral (if market volatility is severe)
2. Smart Contract Risk
Risk Types:
- Code vulnerabilities (may cause fund losses)
- Protocol upgrade risks (may affect existing vaults)
- Governance attacks (malicious proposals may affect protocol)
- Oracle attacks (price data may be manipulated)
Risk Mitigation:
- Choose audited protocols (check audit reports)
- Understand protocol's security record (any past security incidents)
- Don't invest more than you can afford to lose
- Monitor protocol announcements and updates
- Diversify across multiple protocols
3. Market Risk
Price Volatility:
- Collateral price drops (causing collateral ratio to decrease)
- Stablecoin depegging risk (price deviates from $1 USD)
- Liquidity risk (insufficient market liquidity)
Mitigation Strategies:
- Diversify investments (don't put all funds into a single protocol)
- Choose mainstream stablecoins (DAI, USDC, etc.)
- Monitor market dynamics (price, liquidity, etc.)
- Maintain sufficient collateral ratio buffer
- Prepare emergency funds
4. Gas Fee Risk
Risk Types:
- Network congestion causing high Gas fees
- Gas fees may be very high during emergency operations
- Accumulated Gas fees from multiple operations
Mitigation Strategies:
- Choose times when network is not congested
- Use Gas optimization tools (e.g., GasNow, ETH Gas Station)
- Reserve sufficient ETH to pay Gas
- Consider using Layer 2 solutions (if protocol supports)
