Ethena Labs 推出由貝萊德代幣化貨幣市場基金 BUIDL 支持的 USDtb 穩定幣

去中心化金融（DeFi）協議 Ethena Labs 推出了新的穩定幣 USDtb，旨在解決其生態系統內的風險和穩定性問題。

DeFi protocol Ethena Labs has announced the launch of USDtb, a new stablecoin designed to provide a safer and more stable asset within its ecosystem. Backed primarily by BlackRock’s BUIDL tokenized money market fund, USDtb is set to serve as a resilient option during periods of market volatility.

DeFi 協議 Ethena Labs 宣布推出 USDtb，這是一種新的穩定幣，旨在在其生態系統中提供更安全、更穩定的資產。 USDtb 主要由貝萊德的 BUIDL 代幣化貨幣市場基金支持，在市場波動期間將成為一個有彈性的選擇。

The stablecoin is structured similarly to fiat-backed counterparts like USDT and USDC, holding cash and cash-equivalent reserves to maintain a 1:1 peg to the U.S. dollar. However, a key aspect of USDtb's reserves is the 90% allocation to the BUIDL fund, the highest among stablecoins pegged to tokenized real-world assets (RWAs).

該穩定幣的結構與 USDT 和 USDC 等法定貨幣支持的穩定幣類似，持有現金和現金等價物儲備，以維持與美元 1:1 的掛鉤。然而，USDtb 儲備的一個關鍵方面是 90% 分配給 BUIDL 基金，這是與代幣化現實世界資產 (RWA) 掛鉤的穩定幣中最高的。

According to Ethena, this reserve strategy is crucial for scaling USDtb efficiently without encountering liquidity constraints. The stablecoin's launch is part of Ethena's broader strategy to strengthen its financial ecosystem.

Ethena 表示，這種儲備策略對於在不遇到流動性限制的情況下有效擴展 USDtb 至關重要。該穩定幣的推出是 Ethena 加強其金融生態系統的更廣泛策略的一部分。

In a statement, Ethena founder Guy Young highlighted the stablecoin's role in providing users with a diverse risk profile without leaving the protocol's ecosystem.

Ethena 創辦人 Guy Young 在聲明中強調了穩定幣在不離開協議生態系統的情況下為用戶提供多樣化風險狀況的作用。

"In light of the rapidly accelerating demand for different stablecoin options, we saw a clear opportunity to provide a new product that offers users an entirely different risk profile from USDe without them having to leave our trusted ecosystem," Young said.

Young 表示：「鑑於對不同穩定幣選擇的需求迅速增長，我們看到了一個明顯的機會，可以提供一種新產品，為用戶提供與USDe 完全不同的風險狀況，而無需他們離開我們值得信賴的生態系統。

In addition to its internal utility, Ethena also plans to integrate USDtb as a backing asset for Ethena’s flagship yield-bearing token, USDe, during periods of negative derivatives funding rates.

除了其內部效用外，Ethena 還計劃在負衍生性商品融資利率期間將 USDtb 整合為 Ethena 旗艦收益代幣 USDe 的支援資產。

By reallocating hedged positions into USDtb, Ethena aims to stabilize yields and reduce exposure to derivative market risks during bearish trends.

透過將對沖頭寸重新配置為 USDtb，Ethena 旨在穩定收益率並減少看跌趨勢期間的衍生性商品市場風險敞口。

To support USDtb's expansion, Ethena has applied for a $1 billion allocation from Spark's Tokenization Grand Prix program, which aims to scale tokenized RWAs.

為了支持 USDtb 的擴張，Ethena 已從 Spark 的代幣化大獎賽計劃中申請了 10 億美元的撥款，該計劃旨在擴大代幣化 RWA 的規模。

If allocated, the move would further cement Ethena's role in integrating RWAs into DeFi.

如果分配的話，此舉將進一步鞏固 Ethena 在將 RWA 整合到 DeFi 方面的作用。

Ahead of its launch, several security measures were undertaken for USDtb. The stablecoin's smart contracts underwent three audits from Pashov, Quantstamp, and Cyfrin, with no critical or medium-level findings.

在推出之前，USDtb 採取了多項安全措施。該穩定幣的智能合約經過了 Pashov、Quantstamp 和 Cyfrin 的三項審計，沒有出現嚴重或中等程度的發現。

Additionally, a community-led audit by Code4rena also confirmed no significant vulnerabilities.

此外，由 Code4rena 進行的社區主導審核也確認不存在重大漏洞。

For cross-chain functionality, USDtb is being launched as a LayerZero-powered OFT (Omnichain Fungible Token), enabling transfers across Ethereum, Base, Solana, and Arbitrum networks.

對於跨鏈功能，USDtb 將作為 LayerZero 支援的 OFT（Omnichain Fungible Token）推出，支援跨以太坊、Base、Solana 和 Arbitrum 網路的傳輸。

The stablecoin is also integrated with Stargate, serving as the bridge for these cross-chain movements to enhance accessibility for users.

該穩定幣還與 Stargate 集成，作為這些跨鏈運動的橋樑，以增強用戶的可訪問性。

Among the partners for USDtb's launch are Copper, Zodia, Komainu, and Coinbase Web3 Wallet for custodial services, while liquidity is being provided by Jump, Cumberland, Wintermute, Amber, GSR, and SCB Limited.

USDtb 推出的合作夥伴包括 Copper、Zodia、Komainu 和提供託管服務的 Coinbase Web3 Wallet，而提供流動性的有 Jump、Cumberland、Wintermute、Amber、GSR 和 SCB Limited。

The introduction of USDtb comes amid strong investor interest in Ethena's ecosystem, which was further highlighted by a recent surge in ENA governance token prices.

USDtb 的推出正值投資者對 Ethena 生態系統產生濃厚興趣之際，最近 ENA 治理代幣價格的飆升進一步凸顯了這一點。

The token has seen a nearly 100% increase in value over the past month, reaching $1.22, marking its highest level since April 2024 – a 520% rise from its yearly low. Notably, this growth was partially driven by a $500,000 purchase from Trump-affiliated World Liberty Financial.

過去一個月，該代幣的價值上漲了近 100%，達到 1.22 美元，創下 2024 年 4 月以來的最高水平，較年度低點上漲 520%。值得注意的是，這一增長的部分原因是從川普附屬的世界自由金融公司購買了 50 萬美元。
