加密貨幣交易所 Kraken 推出打包比特幣代幣 kBTC

該代幣將在以太坊和 OP 主網上提供。

Major crypto exchange Kraken has launched its own wrapped bitcoin (BTC) token, known as kBTC, according to an exclusive interview with CoinDesk.

根據 CoinDesk 的獨家採訪，主要加密貨幣交易所 Kraken 推出了自己的包裝比特幣 (BTC) 代幣，稱為 kBTC。

The token will be available on both Ethereum and OP Mainnet, and will be backed 1:1 with bitcoin, a company spokesperson told CoinDesk. The bitcoin will be custodied in Kraken Financial, the exchange's U.S. qualified custody solution, in a segregated wallet. The address of this wallet will be made public so that customers can verify the bitcoin is in full reserve.

該公司發言人告訴 CoinDesk，該代幣將在以太坊和 OP 主網上提供，並將以 1:1 的比例與比特幣支持。比特幣將由該交易所的美國合格託管解決方案 Kraken Financial 託管在隔離錢包中。該錢包的地址將被公開，以便客戶可以驗證比特幣是否已全額儲備。

Wrapped tokens, which allow unsupported crypto assets like bitcoin and ether (ETH) to be traded, lent and borrowed on decentralized finance (DeFi) platforms, are used extensively in the DeFi ecosystem. The largest such token, WBTC, enables investors to use their bitcoin on other blockchains, and has a key role in lending DeFi as collateral, with a market capitalization of around $10 billion.

打包代幣允許在去中心化金融 (DeFi) 平台上交易、借貸等不受支援的加密資產，例如比特幣和以太坊 (ETH)，在 DeFi 生態系統中廣泛使用。此類代幣中最大的代幣 WBTC 使投資者能夠在其他區塊鏈上使用其比特幣，並在作為抵押品借貸 DeFi 方面發揮關鍵作用，市值約為 100 億美元。

Kraken is not the only major player to have recently launched a wrapped bitcoin token. There have been a slew of new issues after BitGo, the sole custodian for WBTC, announced a tie up with Tron founder Justin Sun, prompting widespread concern. Rival exchange Coinbase (COIN) launched its own wrapped bitcoin product, the Coinbase Wrapped BTC (cbBTC) on the Ethereum and Base networks, last month.

Kraken 並不是最近推出打包比特幣代幣的唯一主要參與者。 WBTC 唯一託管人 BitGo 宣布與 Tron 創始人孫宇晨合作後，出現了一系列新問題，引發了廣泛關注。競爭對手交易所 Coinbase (COIN) 上個月在以太坊和 Base 網路上推出了自己的包裝比特幣產品 Coinbase Wrapped BTC (cbBTC)。

At launch, kBTC will be supported across several blue-chip DeFi apps, and its partners will include: Kraken, Kraken Wallet, Ethereum, Optimism, Paraswap, Yearn, Gauntlet, deBridge, Definitive, CowSwap, Beefy, Velodrome, Curve and Morpho.

發佈時，kBTC 將在多個藍籌 DeFi 應用程式中得到支持，其合作夥伴包括：Kraken、Kraken Wallet、Ethereum、Optimism、Paraswap、Yearn、Gauntlet、deBridge、Definitive、CowSwap、Beefy、Velodrome、Curve 和 Morpho。

There won't be any supported spot markets for kBTC at launch, Kraken said, but if clients want to use their bitcoin they can redeem it for the underlying and trade it as they would normally do.

Kraken 表示，kBTC 在推出時不會有任何受支援的現貨市場，但如果客戶想要使用他們的比特幣，他們可以將其兌換為標的資產並像平常一樣進行交易。

The minimum deposit size for kBTC on both Ethereum and Optimism will be 0.00026 BTC, which is around $15, assuming a bitcoin price of $60,000.

以太坊和 Optimism 上 kBTC 的最低存款額均為 0.00026 BTC，假設比特幣價格為 60,000 美元，約 15 美元。

The token launch is part of Kraken's mission to accelerate the adoption of DeFi, and kBTC is expected to be widely used across the ecosystem.

此次代幣的推出是 Kraken 加速 DeFi 採用的使命的一部分，kBTC 預計將在整個生態系統中廣泛使用。

"We believe in an onchain future and DeFi represents a key part of that opportunity," said Mark Greenberg, Kraken's global head of asset growth and management, in emailed comments. "kBTC relies on Kraken's long history of seamless UX and top-of-the-range security, bringing DeFi to new users and accelerating the adoption of decentralized applications," he added.

Kraken 全球資產成長和管理主管 Mark Greenberg 在電子郵件評論中表示：“我們相信鏈上的未來，而 DeFi 代表了這一機會的關鍵部分。”他補充說：“kBTC 依靠 Kraken 悠久的無縫用戶體驗和頂級安全性歷史，為新用戶帶來 DeFi，並加速去中心化應用程式的採用。”
