Tokenized treasuries & MMF
USDtb
What it is
一种美元稳定币,储备全额投资于机构级代币化美国国债基金产品,并另设一笔稳定币储备以支持快速赎回。官方文档写明「Initially, USDtb will be backed by BlackRock's USD Institutional Digital Liquidity Fund Token, BUIDL」。发行、赎回与储备管理已于 2025-10-13 移交 Anchorage Digital Bank,Ethena 仅保留技术开发与服务方角色。跨链采用 LayerZero OFT 标准。
How you get out
⛔ 仅 Anchorage Digital Bank 的客户可铸造与赎回,官方原文「Only customers of Anchorage Digital Bank are able to mint and redeem USDtb」。**没有面向普通用户的公开赎回通道。**
What backs it
储备为 BlackRock BUIDL 代币化基金份额 + 一笔稳定币储备,储备金由 Anchorage 持有,透明度页公开托管钱包地址。储备鉴证由 Anchorage Digital Bank 出具。合约经 Pashov Audit Group、Quantstamp、Cyfrin 审计(2024-10)并参加 Code4rena 公开竞赛(2024-11),均无 high/medium 发现。透明度页自带免责声明:非 Anchorage 官方维护。
On-chain contracts
3 address(es) checked with eth_getCode on the chain each token

deployment and is not treated as invalid.

Caveats worth knowing before you use this
- ⛔ 发行方已不是 Ethena。2025-10-13 起由 Anchorage Digital Bank 发行与赎回,Ethena 只是技术方 —— 但 Ethena 官网至今仍用旧口径描述,这是官方自己未同步的坑。
- ⛔ 没有公开赎回通道。只在 Anchorage 开户客户才能进出,把它当「随时可 1:1 赎回的稳定币」是错的。
- symbol() 是混合大小写 `USDtb`,第三方站常写 `USDTB`,按后者做链上验证会失败。
