- Comparison category
- US dollar
- Target value
- 1
- Reference methodology
- USDB is USD-referenced and redeemable through the Blast bridge for DAI rather than directly for fiat.

- Recorded model description
- Protocol Bridged Stablecoin with Native Rebase
- Classification notes
- Protocol-native, bridge-issued, auto-rebasing stablecoin now in announced wind-down with Blast. The DAI bridge exit remains part of the announced withdrawal path; no collapse or irreversible redemption failure is inferred.
Reserve and redemption
Reserve and redemption
Recorded components, disclosures, reports, and redemption conditions remain explicit.Reserve components
- DAI bridge-redemption context with historical MakerDAO on-chain T-bill yield sourcingStablecoin Collateral · This component records the documented protocol dependency and the 2026 wind-down context without asserting asset-level custody, allocation percentage, bankruptcy protection, or uninterrupted yield through shutdown.
| Disclosure status | Official Protocol Description No Asset Level Attestation |
|---|---|
| Backing types | Stablecoin Collateral, Tokenized Fund |
| Summary | Blast documentation historically described USDB as issued when users bridge stablecoins, linked to DAI and protocol reserve income. Blast's October 2026 wind-down materially changes the operating context: the network is unwinding yield infrastructure and directing users to exit to Ethereum. This remains a protocol backing description, not an issuer reserve attestation. |

Deployment status remains active until an effective chain/deployment termination is verified.
