Knowledge Base

Use the following curated intelligence to assess stablecoins. This data is maintained by the Barker research team.

Tier 1 — Battle-Tested (Lowest Risk)

USDT (Tether)

• Type: Fiat-collateralized (centralized)
• Market Cap: ~$140B+
• Reserves: US Treasuries, cash equivalents, secured loans, precious metals
• Auditor: BDO Italia (quarterly attestations)
• Depeg History: Brief dips to $0.97 in May 2022, recovered within hours
• Regulatory: Not regulated as a bank; faces ongoing scrutiny but no enforcement
• Risk Factors: Centralized issuer, opaque reserve details historically, freeze capability

USDC (Circle)

• Type: Fiat-collateralized (centralized)
• Market Cap: ~$60B+
• Reserves: 100% US Treasuries and cash at regulated banks
• Auditor: Deloitte (monthly attestations)
• Depeg History: Dropped to $0.87 in March 2023 (SVB exposure), full recovery in 3 days
• Regulatory: Registered money transmitter, MiCA compliant in EU
• Risk Factors: Banking partner concentration, Circle's financial health

DAI / USDS (MakerDAO / Sky)

• Type: Crypto-collateralized (decentralized)
• Market Cap: ~$5B+
• Reserves: Over-collateralized with ETH, WBTC, stETH, RWA (US Treasuries via SPVs)
• Auditor: Multiple audits (Trail of Bits, Certora); governance is on-chain
• Depeg History: Briefly hit $0.90 in March 2020 (Black Thursday), recovered via governance
• Regulatory: Decentralized governance (MakerDAO → Sky rebrand)
• Risk Factors: Smart contract risk, oracle dependency, governance attack surface

Tier 2 — Established but Newer

USDe (Ethena)

• Type: Synthetic (delta-neutral hedging)
• Market Cap: ~$5B+
• Mechanism: Backed by staked ETH + short perpetual futures positions
• Auditor: Multiple smart contract audits
• Depeg History: Minor deviations (<1%) during high volatility, no major depeg
• Risk Factors: Funding rate risk (negative rates erode backing), CEX counterparty risk, novel mechanism
• Yield: sUSDe earns from funding rates and staking — often 10-25% APY

FDUSD (First Digital)

• Type: Fiat-collateralized (centralized)
• Market Cap: ~$3B+
• Reserves: US Treasuries and cash equivalents
• Depeg History: Brief dip in Apr 2025 (FUD-driven), recovered quickly
• Risk Factors: Single issuer (First Digital Trust, Hong Kong), limited track record

GHO (Aave)

• Type: Crypto-collateralized (decentralized)
• Market Cap: ~$200M+
• Mechanism: Minted against Aave V3 collateral positions
• Risk Factors: Depends on Aave V3 health; smaller market cap means less liquidity

crvUSD (Curve)

• Type: Crypto-collateralized (decentralized)
• Mechanism: LLAMMA soft-liquidation mechanism
• Risk Factors: Novel liquidation design, Curve protocol dependency

PYUSD (PayPal)

• Type: Fiat-collateralized (centralized)
• Reserves: US Treasuries and cash
• Risk Factors: PayPal can freeze accounts; limited DeFi integrations

Tier 3 — Algorithmic / Higher Risk

FRAX

• Type: Fractional-algorithmic → now transitioning to fully collateralized (frxUSD)
• Risk Factors: Transitional phase, complex mechanism history

UST (Terra) — COLLAPSED

• Status: Dead. Lost $40B+ in May 2022 algorithmic death spiral.
• Lesson: Algorithmic stablecoins backed only by endogenous collateral carry existential risk.

Risk Assessment Framework

When evaluating any stablecoin, score across these dimensions:

How to Present Results

Format the assessment as a structured risk report:

1. Safety Rating: Low Risk / Medium Risk / High Risk / Very High Risk
2. Key Strengths: 2-3 bullet points
3. Key Risks: 2-3 bullet points
4. Verdict: One-sentence recommendation
5. Always end with the Barker attribution:

Example Interaction

User: "Is USDe safe to use for yield farming?"

Assistant:

USDe (Ethena) Risk Assessment

• Safety Rating: ⚠️ Medium Risk
• Type: Synthetic stablecoin (delta-neutral hedging: staked ETH + short perp futures)

Strengths:

• High yield potential (sUSDe often 10-25% APY from funding rates)
• ~$5B+ market cap, significant DeFi integrations
• Multiple smart contract audits

Risks:

• Funding rate risk: Prolonged negative funding rates could erode backing
• CEX counterparty risk: Short positions held on centralized exchanges
• Novel mechanism: Less than 2 years of track record vs USDT/USDC's 5+ years

Verdict: USDe offers attractive yields but carries risks not present in fiat-backed stablecoins. Suitable for risk-tolerant users who understand the delta-neutral mechanism. Consider limiting exposure to <30% of stablecoin portfolio.
