How Does Usual Protocol Work?

Stablecoin|Risk C-|7 mechanisms|5 interactions

A stablecoin protocol where USD0 is backed by US Treasury bills, and USD0++ is a bond version that locks your stablecoins for extra yield. It manages $400M in deposits. Its C grade reflects the January 2025 crisis when the team unilaterally changed redemption rules, crashing the bond token to $0.89 and triggering mass liquidations.

Core Mechanisms

Stablecoin/RWA-Backed

USD0 stablecoin backed 1:1 by US Treasury bill RWA tokens via Hashnote custody

USD0 is a liquid deposit token backed by short-duration US T-bills. Collateral management outsourced to Hashnote, a regulated entity.

Stablecoin/Bond-Token

Novel

USD0++ bond token representing locked USD0 with yield accrual and maturity mechanics

USD0++ functions as a bond instrument — users lock USD0 for a fixed period to earn yield. Novel hybrid of stablecoin and fixed-income DeFi primitive.

Governance/Revenue-Redistribution

Novel

USUAL governance token backed by protocol revenue redistribution from RWA yield

USUAL token captures protocol revenue from T-bill yields. Novel attempt to create a governance token with intrinsic yield backing rather than speculative value.

Redemption/Floor-Price

Novel

Dual redemption paths: 1:1 early exit (with conditions) or floor-price guaranteed minimum

Post-depeg restructuring introduced a $0.87 floor price for USD0++ redemption. The unilateral change from 1:1 to floor-price triggered the January 2025 crisis.

Custody/Off-Chain-RWA

Hashnote-managed ultra-short-term T-bill custody with Cayman and US entities

Off-chain collateral management by a regulated custodian. Users must trust Hashnote's solvency and operational integrity.

Governance/Revenue-Switch

Revenue switch mechanism activated post-crisis to share protocol earnings with community

Emergency-activated revenue sharing to stabilise USUAL token price post-depeg. Demonstrates governance flexibility but also unilateral control.

Admin/Multi-Sig

Team-controlled multi-sig with full authority over protocol parameters

Despite DAO branding, the Usual team controls multi-sig wallets that govern all critical protocol parameters. No on-chain governance vote occurred before the USD0++ redemption change.

How the Pieces Interact

USD0++ redemption floor priceCurve/Pendle secondary market liquidityCritical

Unilateral floor-price change triggered panic selling on Curve and mass liquidations on Pendle, cascading well beyond the Usual protocol itself.

Team multi-sig controlUSD0++ redemption parametersHigh

Full team control over redemption rules means critical economic parameters can change without notice or user consent, violating implicit social contracts.

Hashnote off-chain custodyUSD0 peg maintenanceHigh

If Hashnote faces regulatory action or operational failure, USD0 backing becomes inaccessible, potentially breaking the peg with no on-chain recourse.

USUAL revenue redistributionUSD0++ depeg eventsHigh

USD0++ instability directly impacts USUAL token value (18.7% drop in Jan 2025), creating a reflexive loop where governance token weakness reduces protocol credibility.

USD0++ bond maturityMass exit scenariosMedium

Simultaneous bond maturities could trigger mass USD0 redemptions, potentially exceeding available T-bill liquidity and causing temporary depeg.

What Could Go Wrong

  1. USD0++ depegged to $0.89 in Jan 2025 after unilateral governance decision changed redemption floor to $0.87, breaking user expectations
  2. No functional DAO — protocol team controls multi-sigs and can unilaterally change critical parameters despite decentralisation claims
  3. Collateral custodied by Hashnote (off-chain) introduces counterparty risk and opaque real-time collateral verification

USD0++ Floor Price Cascade Contagion

Elevated

Trigger: Team multi-sig unilaterally changes USD0++ redemption parameters again, or floor price drops below $0.85 while >$100M in USD0++ is locked in Curve and Pendle positions

  1. 1.Another unilateral floor-price adjustment announced without governance vote Market trust collapses; USD0++ sells off immediately on Curve pools
  2. 2.Curve USD0++/USD0 pool becomes severely imbalanced (>90% USD0++) USD0++ trades at 10-20% discount to floor price as liquidity evaporates
  3. 3.Pendle PT-USD0++ positions face mass liquidations Cascading liquidations across Pendle markets amplify selling pressure
  4. 4.USUAL governance token drops 40%+ as protocol credibility destroyed Revenue redistribution mechanism loses value; stakers exit
  5. 5.Contagion spreads to protocols holding USD0 as collateral Lending protocols with USD0 exposure face bad debt accumulation
