如何在基础网络上购买和使用美元硬币（USDC）

美元硬币（USDC）是一种与美元挂钩的稳定币。它在加密生态系统中被广泛接受，并且可在多个区块链上使用

USD Coin (USDC) is a stablecoin cryptocurrency that is pegged 1:1 to the US dollar. That means 1 USDC is always $1. It is issued by Circle and has grown to become a top 10 cryptocurrency with a market cap of over $40 billion by the end of 2024.

美元币（USDC）是一种与美元 1:1 挂钩的稳定币加密货币。这意味着 1 USDC 始终等于 1 美元。它由 Circle 发行，到 2024 年底已成长为市值超过 400 亿美元的十大加密货币。

The stablecoin is available on most major cryptocurrency exchanges and is widely accepted in the digital economy. Additionally, it is available across a number of different blockchains, including the Base Network.

该稳定币可在大多数主要加密货币交易所上使用，并在数字经济中被广泛接受。此外，它可以在许多不同的区块链上使用，包括基础网络。

Below, you will learn the step-by-step process of buying USDC on the Base Network. In addition, you’ll get a complete rundown of how the Base Network links to the Ethereum blockchain. So, by the end, you understand how to purchase and start using USDC safely and effectively.

下面，您将了解在基础网络上购买 USDC 的分步过程。此外，您还将获得基础网络如何链接到以太坊区块链的完整概述。因此，到最后，您将了解如何安全有效地购买并开始使用 USDC。

Why use USDC on Base

为什么在 Base 上使用 USDC

So why would you want to use USDC on Base if you can already use it on Ethereum?

那么，如果您已经可以在以太坊上使用 USDC，为什么还要在 Base 上使用它呢？

USDC on Base is a native stablecoin for the Base blockchain, providing a stable and low-cost payment solution within the network. It allows seamless interaction with Base’s ecosystem of decentralized finance (DeFi) applications, such as lending, borrowing and yield farming, all with lower fees compared to Ethereum.

USDC on Base是Base区块链的原生稳定币，在网络内提供稳定且低成本的支付解决方案。它允许与 Base 的去中心化金融 (DeFi) 应用程序生态系统无缝交互，例如贷款、借贷和流动性挖矿，且与以太坊相比，所有费用都较低。

On the other hand, USD Base Coin (USDbC) is a bridged version of USDC specifically for use on Base at the time of its mainnet launch. It allows users to move USDC from Ethereum to Base.

另一方面，美元基础币（USDbC）是 USDC 的桥接版本，专门在主网启动时在 Base 上使用。它允许用户将 USDC 从以太坊转移到 Base。

How to buy USDC on Base Network

如何在基础网络上购买 USDC

You could use Coinbase or any other exchange (supporting the stablecoin) to buy USDC on Base Network. This article uses Coinbase as an example to demonstrate the process.

您可以使用 Coinbase 或任何其他交易所（支持稳定币）在 Base Network 上购买 USDC。本文以Coinbase为例来演示该流程。

With a Coinbase account and wallet, you can store all versions of USDC in a single account. You can then select the Base Network when making transactions to send your USDC on Base.

有了 Coinbase 账户和钱包，您可以将所有版本的 USDC 存储在一个账户中。然后，您可以在进行交易时选择 Base 网络，以在 Base 上发送您的 USDC。

Here are the steps to buy USDC on Base Network using Coinbase:

以下是使用 Coinbase 在 Base Network 上购买 USDC 的步骤：

Create and fund a Coinbase account

创建 Coinbase 账户并为其提供资金

You’ll need to create and verify an exchange account. Then, deposit fiat money (or crypto) into the account.

您需要创建并验证一个交换帐户。然后，将法定货币（或加密货币）存入帐户。

Buy/convert your funds to USDC

购买/将您的资金转换为 USDC

Using the right sidebar, select USDC and input the amount you’d like to purchase before confirming the transaction. This will give you USDC in your account.

使用右侧边栏，选择 USDC 并输入您想要购买的金额，然后确认交易。这将在您的账户中提供 USDC。

Use USDC on Base

在 Base 上使用 USDC

The clever feature of the Coinbase platform is that it tracks all versions of USDC in a single asset account and then bridges it, depending on the chain you want to use.

Coinbase 平台的巧妙功能在于，它可以在单个资产账户中跟踪 USDC 的所有版本，然后根据您想要使用的链来桥接它。

So, if you want to send your USDC to a Base application or wallet, just select the Base Network and Coinbase will route the USDC through Base.

因此，如果您想将 USDC 发送到 Base 应用程序或钱包，只需选择 Base 网络，Coinbase 就会通过 Base 路由 USDC。

Similarly, you can send USDC on Base to your regular Coinbase USDC address. Outside of Coinbase, you may see your funds displayed as USDbC, indicating that they are on the Base Network, but they retain the same value and functionality as USDC.

同样，您可以将 Base 上的 USDC 发送到您的常规 Coinbase USDC 地址。在 Coinbase 之外，您可能会看到您的资金显示为 USDbC，表明它们位于 Base Network 上，但它们保留与 USDC 相同的价值和功能。

Did you know? USDC is fully backed by US dollar-denominated assets. So, there is one dollar held in reserve for each USDC in circulation. This makes it relatively stable, but both the USDC and USDbC prices can fluctuate fractionally, sometimes as much as $0.01

你可知道？ USDC 完全由美元计价资产支持。因此，流通中的每枚 USDC 都持有 1 美元的储备。这使其相对稳定，但 USDC 和 USDbC 的价格可能会出现小幅波动，有时高达 0.01 美元

USDC vs USDbC

USDC 兑 USDbC

USDC Base Coin (USDbC) is a bridged version of the USDC stablecoin that runs on the Ethereum blockchain. The original USDC cryptocurrency is pegged 1:1 to the US dollar, meaning one token is always worth $1. This is also true for bridged versions of the coin, which enable it to be used on layer-2 blockchains.

USDC 基础币（USDbC）是运行在以太坊区块链上的 USDC 稳定币的桥接版本。最初的 USDC 加密货币与美元 1:1 挂钩，这意味着一个代币始终价值 1 美元。对于桥接版本的代币来说也是如此，这使其能够在第 2 层区块链上使用。

Base is one of these layer-2 blockchains. It is a network developed by Coinbase that was designed to solve issues of scalability on Ethereum. In simple terms, Base is a blockchain built on top of Ethereum. It inherits the fundamentals and security of Ethereum, but has different protocols added to offer more flexibility and scale.

Base 是这些第 2 层区块链之一。它是由 Coinbase 开发的网络，旨在解决以太坊的可扩展性问题。简单来说，Base 是建立在以太坊之上的区块链。它继承了以太坊的基本原理和安全性，但添加了不同的协议以提供更大的灵活性和规模。

To use the Ethereum USDC stablecoin to transact on the Base blockchain, you need to “bridge” or transfer it across blockchains. When you bridge a USDC token, the original USDC is locked to the Ethereum network. Then, you are given the equivalent amount of USDbC on the Base Network.

要使用以太坊 USDC 稳定币在 Base 区块链上进行交易，您需要跨区块链“桥接”或转移它。当您桥接 USDC 代币时，原始 USDC 会被锁定到以太坊网络。然后，您将在基础网络上获得等值的 USDbC。

You can then freely transact on Base with the relevant stablecoin tokens, plus you can always reverse the bridge to move back to the original Ethereum USDC.

然后，您可以在 Base 上自由地使用相关稳定币代币进行交易，此外您还可以随时反转桥接器以返回到原始的以太坊 USDC。

To make things easier and remove some of these technicalities, several platforms enable you to buy USDC on Base using fiat and other cryptocurrencies.

为了让事情变得更容易并消除其中一些技术细节，一些平台允许您使用法定货币和其他加密货币在 Base 上购买 USDC。
