What Are Stablecoins?
Stablecoins are cryptocurrencies designed to maintain a stable value relative to a reference asset, typically the US Dollar. Unlike Bitcoin or Ethereum, which can fluctuate dramatically, stablecoins aim to provide the benefits of cryptocurrency (fast transfers, programmability) without the volatility.
Why Stablecoins Matter
- • Bridge between traditional finance and crypto
- • Enable trading without converting to fiat
- • Facilitate DeFi lending and borrowing
- • Provide stability for everyday transactions

How Stablecoins Maintain Their Peg
Different stablecoins use various mechanisms to maintain their $1 peg:
USDT/USDC Approach
- • Hold USD reserves in bank accounts
- • 1:1 backing ratio (ideally)
- • Redemption mechanism
- • Regular audits/attestations
DAI Approach
- • Over-collateralized with crypto
- • Liquidation mechanisms
- • Stability fees and rates
- • Governance-driven parameters
Risks and Considerations
Important Risks
- • Centralization risk: Fiat-backed stablecoins can be frozen
- • Regulatory risk: Government actions can affect operations
- • Depeg risk: Stablecoins can lose their $1 peg temporarily
- • Counterparty risk: Trust in the issuing organization
- • Smart contract risk: Bugs in decentralized stablecoins
Use Cases for Stablecoins
Stablecoins serve multiple purposes in the crypto ecosystem:
- Trading: Avoid volatility between trades
- DeFi: Lending, borrowing, and yield farming
- Payments: Cross-border transfers and remittances
- Store of value: Temporary parking for crypto gains
- Arbitrage: Taking advantage of price differences
