Why Failed Stablecoins Reveal a Crisis of Trust

The dominant model (e.g., USDC, Tether) outsources trust to regulated banks. This creates a single point of failure and censorship, directly contradicting crypto's decentralized ethos.

• Systemic Risk: Relies on opaque, off-chain reserves.
• Censorship Vector: Can be frozen by issuer or government order.
• Capital Inefficiency: Requires 1:1 fiat backing, limiting scalability.

Projects like TerraUSD (UST) attempted to automate trust via on-chain mechanisms and arbitrage incentives. This failed catastrophically when the reflexive feedback loop broke.

• Reflexive Collapse: Death spiral triggered by loss of peg confidence.
• Oracle Dependency: Relies on external price feeds for stability.
• Ponzi Dynamics: Growth dependent on unsustainable yields from protocols like Anchor.

MakerDAO's DAI pioneered a trust-minimized model where stability is backed by excess crypto collateral. This shifts trust from entities to transparent, overcapitalized smart contracts.

• Transparent Reserves: All collateral is on-chain and verifiable.
• Censorship-Resistant: No central issuer can freeze assets.
• Capital Inefficiency: Requires >150% collateralization, limiting supply scalability.

The next evolution blends on-chain efficiency with real-world trust. MakerDAO integrates Real-World Assets (RWAs), while intent-based systems like UniswapX and CowSwap abstract settlement complexity.

• Hybrid Trust: Combines crypto-native overcollateralization with regulated asset exposure.
• User Sovereignty: Intent architectures let users specify what they want, not how to achieve it.
• Efficiency Gain: Enables higher capital efficiency than pure crypto-collateral models.

The problem was a circular dependency: UST's peg relied on arbitrage with a volatile governance token (LUNA), creating a death spiral. The solution was never built—a genuine, verifiable last-resort asset backing.

• Failure Point: No exogenous collateral. The $40B+ collapse was a mathematical certainty under stress.
• Design Flaw: Misplaced trust in reflexive, game-theoretic mechanisms over real-world asset custody.

The problem was fraudulent, commingled custody. 'Stable' assets like SRM were backed by exchange-held FTT and customer funds. The solution is the antithesis of this model: on-chain, verifiable proof-of-reserves.

• Failure Point: Opaque, centralized control. Assets were IOUs on a broken balance sheet.
• Contrast: Compare to MakerDAO's transparent, on-chain collateral vaults and Circle's monthly attestations.

The problem was a 'fractional-algorithmic' hybrid that promised but failed to deliver stability. Its partial USDC backing was insufficient during a bank run, exposing the algorithmic portion as worthless. The solution is full-reserve design or overcollateralization.

• Failure Point: ~75% USDC backing proved inadequate when the ~25% algorithmic token (TITAN) hyper-inflated to zero.
• Lesson: Hybrid models concentrate risk; trust must be anchored in the most stable component.

The solution is enforceable, verifiable responsibility. MakerDAO operates with ~150%+ overcollateralization in on-chain assets, enforced by smart contracts. Circle submits to regulated custody and monthly attestations. Trust is engineered, not assumed.

• Key Mechanism: Transparent, real-time solvency proofs versus opaque promises.
• Result: These models survive black swan events because the fiduciary duty is structurally embedded.

Stablecoins like Tether (USDT) and USD Coin (USDC) have faced scrutiny over their reserve composition. The crisis occurs when assets are illiquid, unverified, or simply not there, as seen with Terra's UST.

• Require Real-Time Attestations: Monthly reports are insufficient. Look for Chainlink Proof of Reserve or similar on-chain verification.
• Demand High-Quality Collateral: >80% should be in cash, cash equivalents, and short-duration treasuries. Avoid commercial paper and corporate debt.

Pure algorithmic models like Terra's UST/LUNA or Iron Finance's IRON/TITAN rely on reflexive, game-theoretic mechanisms that fail under extreme volatility and bank-run conditions.

• Reject Pure Seigniorage: A stablecoin backed only by its own volatile governance token is a Ponzi.
• Insist on Hybrid Models: Protocols like Frax Finance (FRAX) combine algorithmic and collateralized elements, creating a circuit breaker against death spirals.

The ultimate fiduciary standard is removing human discretion. MakerDAO's DAI and Liquity's LUSD are overcollateralized by on-chain assets held in non-custodial smart contracts.

• Verify Collateral On-Chain: ETH or stETH in a public smart contract is auditable by anyone, in real-time.
• Enforce Strict Ratios: Liquity maintains a minimum 110% collateral ratio, enforced by immutable code, preventing undercollateralization.

Centralized issuers can freeze assets or change rules unilaterally, as Circle did with USDC on Tornado Cash. Decentralized governance aligns incentives but must be structured correctly.

• Prioritize Stake-Weighted Voting: MKR token holders in MakerDAO are directly exposed to protocol solvency.
• Avoid Governance Minimalism: Protocols like Reserve Rights (RSV) and Fei Protocol learned that active, engaged governance is required to manage collateral and respond to crises.

Even "collateralized" stablecoins fail if the custodian fails. The SVB collapse temporarily depegged USDC, proving its reliance on the traditional banking system.

• Map Counterparty Risk: Identify all banks, custodians, and asset managers. Demand diversification.
• Prefer Native Crypto Backing: DAI's shift to holding ~35% in USDC reintroduced centralized risk, a regression from its ETH-centric model.

The final test of a stablecoin is the ability to exit at par, on-demand. This requires deep liquidity and a robust redemption mechanism.

• Audit the Primary Market: Can you always redeem 1 stablecoin for $1 of underlying assets directly with the protocol? Liquity's stability pool and redemption mechanism ensure this.
• Scrutinize Secondary Markets: A stablecoin that only holds its peg on specific CEX order books is fragile. Look for Uniswap v3 concentrated liquidity pools with $100M+ depth.
