Asset Architecture
The Four Pillars of Digital Stable Value
Every major stable instrument on earth derives from one of four collateral architectures. We track reserves, redemption mechanics, and failure modes for each.
Fiat-Backed
Bank deposits & T-bills · 1:1 redemption
The dominant architecture. Fully reserved tokens — USDT, USDC, FDUSD, PYUSD — collateralized by cash and short-dated sovereign debt, subject to emerging issuer licensing regimes.
- Dominant architecture by circulating supply (see metrics register)
- Key risk: reserve opacity & issuer concentration
- 2027 focus: prudential floors & attestation cadence
Crypto-Backed
Overcollateralized on-chain debt
DAI / USDS and variants minted against excess on-chain collateral (ETH, BTC, RWA). Transparent, censorship-resistant, and governed by decentralized treasuries.
- Overcollateralized by design; ratios vary by vault and asset type
- Key risk: liquidation cascades in volatility
- 2027 focus: RWA collateral treatment rules
Algorithmic
Seigniorage & dual-token mechanics
Supply-elastic designs that expand and contract issuance via incentive curves rather than hard collateral. Rebuilt after 2022, now returning in tightly-capped institutional pilots.
- Regulatory status varies by jurisdiction (see register)
- Key risk: reflexive de-peg spirals
- 2027 focus: EU/US pilot caps & wind-down rules
RWA-Backed
Tokenized treasuries, credit & commodities
The newest pillar by design: tokenized T-bills, private credit, trade finance, gold and carbon. The bridge between traditional finance and on-chain liquidity.
- Supply ranking maintained in the metrics register
- Key risk: custody & legal enforceability
- 2027 focus: cross-border custody standards
