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.

知名风险投资公司正在联手培育 Polkadot 区块链网络上的去中心化金融 (DeFi) 的发展。基于 Polkadot 的 DeFi 中心网络 Acala (ACA) 宣布成立 2.5 亿美元的“aUSD 生态系统基金”，以培育 Polkadot 蓬勃发展的 DeFi 生态系统中的初创企业。该基金专门用于支持开发 Acala 美元 (aUSD) 用例的团队，这是一种加密货币支持的稳定币，有望成为 Polkadot 及其金丝雀网络 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.

该基金吸引了超过 30 家风险投资公司的投资，包括 Hypersphere、Pantera 和 Jump Crypto。值得注意的是，CoinDesk 的母公司数字货币集团也是参与者。

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 首席增长官 Dan Reecer 将该计划描述为致力于 Polkadot 生态系统整体增长的利益相关者之间的“集体努力”。 Reecer 表示：“aUSD 生态系统基金是我们团结起来围绕共同愿景的催化剂，即将 aUSD 打造为基础流动性工具，让 Polkadot 经济充分发挥潜力。”

Polkadot and Stablecoins: A Symbiotic Relationship

波卡和稳定币：共生关系

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 多年来致力于为多链加密生态系统构建基础设施，使各种区块链能够共存并满足不同的用例。 Polkadot 网络是第 0 层区块链，它提供了一个安全的基础，其中第 1 层“平行链”（例如 Acala）可以无缝互操作。 Polkadot 的中心辐射型架构旨在为目前用于在独立区块链之间交换信息的不稳定的跨链“桥梁”提供更强大的替代方案。

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 自称为“Polkadot 的 DeFi 中心”，是第一个在网络上启动的平行链。今年 2 月，Acala 推出了 aUSD 作为 Polkadot 和 Kusama 的默认稳定币。

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 等稳定币是加密货币，旨在与基础资产（通常是美元）的价值保持稳定挂钩。这些价格稳定的代币对于以太坊等其他区块链上 DeFi 协议的扩散发挥了重要作用。在 DeFi 应用中，稳定币为抵押品提供了一种波动性较小的媒介，促进了借贷等活动。

aUSD: A Crypto-Backed Stablecoin on Polkadot

aUSD：Polkadot 上的加密货币支持的稳定币

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“加密货币支持”稳定币的模式，采用超额抵押来维持其挂钩。 aUSD 作为超额抵押贷款发行，抵押品价值会自动调整，以将 aUSD 的交易价格保持在 1 美元左右。目前，aUSD 接受 DOT（原生 Polkadot 代币）、Acala 的 ACA 代币和 LDOT（用于 Acala 流动性质押的 DOT 变体）作为抵押品。

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

根据 Acala 官方仪表板，截至目前，aUSD 的流通供应量为 700 万美元，并有 7200 万美元的抵押品支持。

Partnerships for Success

成功的合作伙伴关系

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.

除了风险基金之外，Acala 还与网络中九个最大的平行链合作实施 aUSD 计划。 Reecer 表示：“这种合作使我们能够协同努力，培育由 aUSD 流动性驱动的强劲 Polkadot 经济。”

Conclusion

结论

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.

价值 2.5 亿美元的 aUSD 生态系统基金得到了一系列领先风险公司和 Polkadot 最大的平行链的支持，代表着对 Polkadot 网络上 DeFi 未来的重大投资。该举措旨在加强生态系统，特别是通过支持基于 aUSD 的初创公司，并最终为 Polkadot 经济的扩张做出贡献。随着 DeFi 格局的不断发展，Polkadot 通过其多链架构和稳定币基础，将自己定位为去中心化金融领域的强大参与者。
