Is Ethena USDtb Safe?
Risk Grade: B- (28/100)
Ethena USDtb is rated as moderate risk — some novel mechanisms, generally well-understood.
Ethena USDtb is one of the safest stablecoins in DeFi with a B+ risk grade, backed by US Treasury securities through BlackRock's BUIDL fund and custodied by a federally regulated bank. The main risks are concentration in a single reserve fund and regulatory uncertainty around RWA-backed stablecoins. It is not a yield product — use USDtb for stability and capital preservation, not returns. Solid choice for conservative DeFi users.
Ethena USDtb is a stablecoin backed primarily by BlackRock's BUIDL fund, which invests in US government debt and treasury bills. Unlike Ethena's riskier USDe synthetic dollar, USDtb has traditional asset backing — over 90% in US Treasury securities through the world's largest asset manager. It is issued through Anchorage Digital, a federally chartered US crypto bank, making it one of the most regulated stablecoin products in DeFi.

Key Risks for Ethena USDtb Users

Regulatory changes around tokenized securities could force USDtb to change its structure or shut down
The stablecoin is connected to Ethena's broader system — problems with USDe could create confusion around USDtb
Cross-chain deployments (like JupUSD on Solana) add bridge-related risks
