USDtb

Operating

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 is deployed on. An address returning 0x on Ethereum mainnet is normal for an L2 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。
