USDC 穩定幣擴展到 zkSync，現已支援 16 個區塊鏈

Stablecoin issuer Circle has expanded support for its native stablecoin, USD Coin (USDC), to Ethereum zero-knowledge layer-2 solution zkSync.

穩定幣發行商 Circle 已將其原生穩定幣 USD Coin (USDC) 的支援擴展到以太坊零知識第 2 層解決方案 zkSync。

“Many leading ecosystem apps and DeFi protocols are expected to support native USDC on zkSync for payments, trading, borrowing, lending,” wrote Circle in its April 9 announcement; developers can use USDC on zkSync to build on a stable foundation that’s built to last and officially supported by Circle. With the addition of zkSync, USDC is now supported on 16 blockchains, including Ethereum, Solana, Base, Arbitrum, and others. 

Circle 在 4 月 9 日的公告中寫道：「許多領先的生態系統應用程式和 DeFi 協議預計將支援 zkSync 上的原生 USDC 進行支付、交易、借貸」。開發人員可以在 zkSync 上使用 USDC 建立持久穩定的基礎，並得到 Circle 的官方支援。隨著 zkSync 的加入，USDC 現在支援 16 個區塊鏈，包括以太坊、Solana、Base、Arbitrum 等。

Zero-knowledge proofs determine the integrity of a transaction without disclosing the supporting evidence. Meanwhile, rollups bundle transactions off the Ethereum main layer and club them into a single transaction. Together, they form the core of the zkSync technology, which processes transactions at record speed and low cost at layer 2 and sends the finalized proof back to the Ethereum mainnet. As of April 9, 2024, the zkSync ecosystem includes over 180 decentralized applications and over 5.7 million unique active wallet addresses over the last 30 days.

零知識證明無需披露支持證據即可確定交易的完整性。同時，匯總將以太坊主層的交易捆綁在一起，並將它們組合成一個交易。它們共同構成了 zkSync 技術的核心，該技術在第 2 層以創紀錄的速度和低成本處理交易，並將最終的證明發送回以太坊主網。截至 2024 年 4 月 9 日，zkSync 生態系統包括過去 30 天內超過 180 個去中心化應用程式和超過 570 萬個獨特的活躍錢包地址。

Like USDC on other blockchains, the zkSync USDC can be redeemed one-for-one for U.S. dollars directly via Circle or via digital wallets and exchanges. The zkSync USDC can also be swapped for other USDCs via cross-chain bridges. Institution investors can also access the stablecoin via Circle Mint. “Businesses and developers use zkSync to benefit from fast, low cost transactions and native account abstraction,” Circle wrote, adding that “zkSync is on a mission to increase Ethereum’s throughput, and to fully preserve its foundational values.”

與其他區塊鏈上的 USDC 一樣，zkSync USDC 可以直接透過 Circle 或透過數位錢包和交易所一對一兌換美元。 zkSync USDC 也可以透過跨鏈橋交換為其他 USDC。機構投資者還可以透過 Circle Mint 取得穩定幣。 Circle 寫道：「企業和開發人員使用zkSync 來受益於快速、低成本的交易和本機帳戶抽象。」他補充道，「zkSync 的使命是提高以太坊的吞吐量，並充分保留其基本價值。 」

Circle has been mostly expanding access to USDC to other blockchains, although it has halted such efforts from time to time. On Feb. 21, Circle abruptly ceased USDC minting on the Tron blockchain. Circle did not give a reason for ending Tron support, only saying it “continually assesses the suitability of all blockchains” as part of its risk management process. 

Circle 一直在將 USDC 的訪問範圍擴大到其他區塊鏈，儘管它不時停止此類努力。 2 月 21 日，Circle 突然停止在 Tron 區塊鏈上鑄造 USDC。 Circle 沒有給出終止 Tron 支援的原因，只是表示它“不斷評估所有區塊鏈的適用性”，作為其風險管理流程的一部分。

Last year, the U.S. Securities and Exchange Commission sued Justin Sun and the Tron Foundation alleging they offered unregistered securities and conducted manipulative trading, which Sun denies.

去年，美國證券交易委員會起訴孫宇晨和波場基金會，指控他們提供未經註冊的證券並進行操縱交易，孫宇晨對此予以否認。
