cbBTC詳情

Coinbase users can now convert their Bitcoin to cbBTC when transferring from their accounts to Base or Ethereum addresses. This token can be used in popular DeFi protocols like Aave (AAVE), Compound (COMP), and MakerDAO, allowing users to lend, borrow, and earn yields with their Bitcoin.

Coinbase 用戶現在可以在從其帳戶轉移到 Base 或以太坊地址時將其比特幣轉換為 cbBTC。該代幣可用於流行的 DeFi 協議，如 Aave (AAVE)、Compound (COMP) 和 MakerDAO，允許用戶以比特幣進行借貸和賺取收益。

CbBTC also ensures secure liquidity by being fully backed by Bitcoin held in Coinbase custody, which has a track record of over 10 years. This move aims to provide more utility for Bitcoin holders, allowing them to access decentralized finance applications using the Bitcoin they already own.

CbBTC 也受到 Coinbase 託管的比特幣的完全支持，確保了安全的流動性，Coinbase 擁有超過 10 年的追蹤記錄。此舉旨在為比特幣持有者提供更多實用性，使他們能夠使用他們已經擁有的比特幣訪問去中心化金融應用程式。

How cbBTC works

cbBTC 是如何運作的

When sending BTC from Coinbase to an address on Base or Ethereum, it will be automatically converted 1:1 to cbBTC. When receiving cbBTC in the Coinbase account, it will be converted 1:1 from cbBTC to BTC.

當從 Coinbase 發送 BTC 到 Base 或以太坊上的地址時，它會自動 1:1 轉換為 cbBTC。當Coinbase帳戶收到cbBTC時，將會從cbBTC 1:1轉換為BTC。

CbBTC will not have a separate order book or trading pair on Coinbase. However, it will be available to trade on DEXs using Coinbase Wallet and may be listed on other third-party exchanges that choose to support it.

CbBTC 在 Coinbase 上不會有單獨的訂單簿或交易對。但是，它將可以使用 Coinbase 錢包在 DEX 上進行交易，並且可能會在選擇支援它的其他第三方交易所上市。

At launch, cbBTC send and receive will be available on Coinbase in the U.S. (excluding New York State), the UK, EEA states, Singapore, Australia, and Brazil. It will also be accessible globally on Base and Ethereum.

推出後，cbBTC 發送和接收將在美國（紐約州除外）、英國、歐洲經濟區國家、新加坡、澳洲和巴西的 Coinbase 上提供。它還可以在 Base 和以太坊上在全球範圍內訪問。
