Prominent venture firms are joining forces to nurture the growth of decentralized finance (DeFi) on the Polkadot blockchain network. Acala (ACA), a Polkadot-based DeFi-centric network, announced the establishment of a $250 million "aUSD Ecosystem Fund" to foster startups within Polkadot's burgeoning DeFi ecosystem. The fund is specifically designed to support teams developing use cases for the Acala dollar (aUSD), a crypto-backed stablecoin poised to become the cornerstone of DeFi on Polkadot and its canary network, Kusama.

知名創投公司正在聯手培育 Polkadot 區塊鏈網路上的去中心化金融 (DeFi) 的發展。基於 Polkadot 的 DeFi 中心網路 Acala (ACA) 宣布成立 2.5 億美元的“aUSD 生態系統基金”，以培育 Polkadot 蓬勃發展的 DeFi 生態系統中的初創企業。該基金專門用於支援開發 Acala 美元 (aUSD) 用例的團隊，這是一種加密貨幣支援的穩定幣，有望成為 Polkadot 及其金絲雀網路 Kusama 上 DeFi 的基石。

The fund has attracted investments from over 30 venture firms, including Hypersphere, Pantera, and Jump Crypto. Notably, Digital Currency Group, the parent company of CoinDesk, is also a participant.

該基金吸引了超過 30 家創投公司的投資，包括 Hypersphere、Pantera 和 Jump Crypto。值得注意的是，CoinDesk 的母公司數位貨幣集團也是參與者。

Dan Reecer, Acala's Chief Growth Officer, described the initiative as a "collective effort" among stakeholders committed to the overall growth of the Polkadot ecosystem. "The aUSD Ecosystem Fund serves as a catalyst for us to unite around a shared vision of establishing aUSD as a foundational liquidity tool that will empower the Polkadot economy to reach its full potential," Reecer stated.

Acala 首席成長長 Dan Reecer 將該計劃描述為致力於 Polkadot 生態系統整體成長的利益相關者之間的「集體努力」。 Reecer 表示：“aUSD 生態系統基金是我們團結起來圍繞共同願景的催化劑，即將 aUSD 打造為基礎流動性工具，讓 Polkadot 經濟充分發揮潛力。”

Polkadot and Stablecoins: A Symbiotic Relationship

波卡和穩定幣：共生關係

Polkadot has dedicated years to constructing infrastructure for a multi-chain crypto ecosystem, enabling various blockchains to coexist and cater to diverse use cases. The Polkadot network, a layer 0 blockchain, provides a secure foundation where layer 1 "parachains" such as Acala can interoperate seamlessly. Polkadot's hub-and-spoke architecture aims to offer a more robust alternative to the volatile cross-chain "bridges" currently employed to exchange information between independent blockchains.

Polkadot 多年來致力於為多鏈加密生態系統建立基礎設施，使各種區塊鏈能夠共存並滿足不同的用例。 Polkadot 網路是第 0 層區塊鏈，它提供了一個安全的基礎，其中第 1 層「平行鏈」（例如 Acala）可以無縫互通。 Polkadot 的中心輻射型架構旨在為目前用於在獨立區塊鏈之間交換資訊的不穩定的跨鏈「橋樑」提供更強大的替代方案。

Acala, self-proclaimed as "The DeFi Hub of Polkadot," holds the distinction of being the first parachain to launch on the network. In February, Acala introduced aUSD as the default stablecoin for both Polkadot and Kusama.

Acala 自稱為“Polkadot 的 DeFi 中心”，是第一個在網路上啟動的平行鏈。今年 2 月，Acala 推出了 aUSD 作為 Polkadot 和 Kusama 的預設穩定幣。

Stablecoins like USDC, DAI, and aUSD are cryptocurrencies designed to maintain a stable peg to the value of an underlying asset, typically the US dollar. These price-stable tokens have been instrumental in the proliferation of DeFi protocols on other blockchains such as Ethereum. In DeFi applications, stablecoins offer a less volatile medium for collateral, facilitating activities like lending and borrowing.

USDC、DAI 和 aUSD 等穩定幣是加密貨幣，旨在與基礎資產（通常是美元）的價值保持穩定掛鉤。這些價格穩定的代幣對於以太坊等其他區塊鏈上 DeFi 協議的擴散發揮了重要作用。在 DeFi 應用中，穩定幣為抵押品提供了一種波動性較小的媒介，促進了借貸等活動。

aUSD: A Crypto-Backed Stablecoin on Polkadot

aUSD：Polkadot 上的加密貨幣支援的穩定幣

aUSD follows the model of other "crypto-backed" stablecoins like DAI, employing over-collateralization to maintain its peg. aUSD is issued as an overcollateralized loan, with the collateral value automatically adjusted to keep aUSD's trading price around $1. Currently, aUSD accepts DOT, the native Polkadot token, Acala's ACA token, and LDOT, a variant of DOT used for liquid staking on Acala, as collateral.

aUSD 遵循 DAI 等其他「加密貨幣支持」穩定幣的模式，採用超額抵押來維持其掛鉤。 aUSD 作為超額抵押貸款發行，抵押品價值會自動調整，以將 aUSD 的交易價格保持在 1 美元左右。目前，aUSD 接受 DOT（原生 Polkadot 代幣）、Acala 的 ACA 代幣和 LDOT（用於 Acala 流動性質押的 DOT 變體）作為抵押品。

As of today, aUSD has a circulating supply of $7 million, backed by $72 million in collateral, according to official Acala dashboards.

根據 Acala 官方儀表板，截至目前，aUSD 的流通供應量為 700 萬美元，並有 7,200 萬美元的抵押品支持。

Partnerships for Success

成功的合作夥伴關係

In addition to the venture fund, Acala has partnered with nine of the network's largest parachains for the aUSD initiative. "This collaboration allows us to synergize our efforts, fostering a robust Polkadot economy that is driven by aUSD liquidity," Reecer remarked.

除了創投基金之外，Acala 還與網路中九個最大的平行鏈合作實施 aUSD 計畫。 Reecer 表示：“這種合作使我們能夠協同努力，培育由 aUSD 流動性驅動的強勁 Polkadot 經濟。”

Conclusion

結論

The $250 million aUSD Ecosystem Fund, supported by an array of leading venture firms and Polkadot's largest parachains, represents a significant investment in the future of DeFi on the Polkadot network. This initiative aims to bolster the ecosystem, particularly by supporting startups building on aUSD, and ultimately contribute to the expansion of the Polkadot economy. As the DeFi landscape continues to evolve, Polkadot, through its multi-chain architecture and stablecoin foundations, positions itself as a formidable player in the decentralized finance arena.

價值 2.5 億美元的 aUSD 生態系統基金得到了一系列領先風險公司和 Polkadot 最大的平行鏈的支持，代表著對 Polkadot 網路上 DeFi 未來的重大投資。該舉措旨在加強生態系統，特別是透過支持基於 aUSD 的新創公司，並最終為 Polkadot 經濟的擴張做出貢獻。隨著 DeFi 格局的不斷發展，Polkadot 透過其多鏈架構和穩定幣基礎，將自己定位為去中心化金融領域的強大參與者。
