如何在基礎網路上購買和使用美元硬幣（USDC）

美元硬幣（USDC）是一種與美元掛鉤的穩定幣。它在加密生態系統中被廣泛接受，並且可在多個區塊鏈上使用

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.

美元幣（USDC）是一種與美元 1:1 掛鉤的穩定幣加密貨幣。這意味著 1 USDC 始終等於 1 美元。它由 Circle 發行，到 2024 年底已成長為市值超過 400 億美元的十大加密貨幣。

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.

該穩定幣可在大多數主要加密貨幣交易所上使用，並在數位經濟中被廣泛接受。此外，它可以在許多不同的區塊鏈上使用，包括基礎網路。

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，您將了解在基礎網路上購買 USDC 的逐步過程。此外，您還將獲得基礎網路如何連結到以太坊區塊鏈的完整概述。因此，到最後，您將了解如何安全有效地購買並開始使用 USDC。

Why use USDC on Base

為什麼在 Base 上使用 USDC

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

那麼，如果您已經可以在以太坊上使用 USDC，為什麼還要在 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區塊鏈的原生穩定幣，在網路內提供穩定且低成本的支付解決方案。它允許與 Base 的去中心化金融 (DeFi) 應用程式生態系統無縫交互，例如貸款、借貸和流動性挖礦，且與以太坊相比，所有費用都較低。

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，美元基礎幣（USDbC）是 USDC 的橋接版本，專門在主網啟動時在 Base 上使用。它允許用戶將 USDC 從以太坊轉移到 Base。

How to buy USDC on Base Network

如何在基礎網路上購買 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（支援穩定幣）在 Base Network 上購買 USDC。本文以Coinbase為例來示範此流程。

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 帳戶和錢包，您可以將所有版本的 USDC 儲存在一個帳戶中。然後，您可以在進行交易時選擇 Base 網絡，以在 Base 上發送您的 USDC。

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

以下是使用 Coinbase 在 Base Network 上購買 USDC 的步驟：

Create and fund a Coinbase account

建立 Coinbase 帳戶並為其提供資金

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

您需要建立並驗證一個交換帳戶。然後，將法定貨幣（或加密貨幣）存入帳戶。

Buy/convert your funds to USDC

購買/將您的資金轉換為 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.

使用右側邊欄，選擇 USDC 並輸入您想要購買的金額，然後確認交易。這將在您的帳戶中提供 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 平台的巧妙功能在於，它可以在單一資產帳戶中追蹤 USDC 的所有版本，然後根據您想要使用的鏈來橋接它。

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，如果您想將 USDC 發送到 Base 應用程式或錢包，只需選擇 Base 網絡，Coinbase 就會透過 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.

同樣，您可以將 Base 上的 USDC 發送到您的常規 Coinbase USDC 地址。在 Coinbase 之外，您可能會看到您的資金顯示為 USDbC，表明它們位於 Base Network 上，但它們保留與 USDC 相同的價值和功能。

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 完全由美元計價資產支持。因此，流通中的每枚 USDC 都持有 1 美元的儲備。這使其相對穩定，但 USDC 和 USDbC 的價格可能會出現小幅波動，有時高達 0.01 美元

USDC vs USDbC

USDC 兌 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 基礎幣（USDbC）是運行在以太坊區塊鏈上的 USDC 穩定幣的橋接版本。最初的 USDC 加密貨幣與美元 1:1 掛鉤，這意味著一個代幣始終價值 1 美元。對於橋接版本的代幣也是如此，這使其能夠在第 2 層區塊鏈上使用。

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 是這些第 2 層區塊鏈之一。它是由 Coinbase 開發的網絡，旨在解決以太坊的可擴展性問題。簡單來說，Base 是建立在以太坊之上的區塊鏈。它繼承了以太坊的基本原理和安全性，但添加了不同的協議以提供更大的靈活性和規模。

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 穩定幣在 Base 區塊鏈上進行交易，您需要跨區塊鏈「橋接」或轉移它。當您橋接 USDC 代幣時，原始 USDC 會被鎖定到以太坊網路。然後，您將在基礎網路上獲得等值的 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.

然後，您可以在 Base 上自由地使用相關穩定幣代幣進行交易，此外您還可以隨時反轉橋接器以返回原始的以太坊 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.

為了讓事情變得更容易並消除其中一些技術細節，一些平台允許您使用法定貨幣和其他加密貨幣在 Base 上購買 USDC。

How to transfer USDC from Ethereum to Base

如何將 USDC 從以太幣轉移到 Base

Here are the steps to bridge USDC from Ethereum to Base:

以下是將 USDC 從以太坊橋接到 Base 的步驟：

Setting up your wallet: To start, you’ll need a USDbC-compatible crypto wallet. You can add Base tokens to wallets like MetaMask for self-custody or use the native Coinbase wallet and

設定您的錢包：首先，您需要一個與 USDbC 相容的加密錢包。您可以將 Base 代幣新增至 MetaMask 等錢包進行自我託管，或使用原生 Coinbase 錢包
