什麼是Defi錢包，它如何工作？

在過去的幾年中，加密貨幣已變得非常流行，因此，分散的金融（DEFI）空間也爆炸了。

Cryptocurrency has become incredibly popular over the past few years, and as a result, the decentralized finance (DeFi) space has also exploded in popularity. Fueling this explosion in a major way is the DeFi core principle of removing intermediaries and empowering individual users to borrow, lend, trade, and even earn yields directly on blockchain networks.

在過去的幾年中，加密貨幣已變得非常流行，因此，分散的金融（DEFI）空間也爆炸了。以主要方式加劇這種爆炸的是消除中介機構並授權各個用戶借入，借入，貿易甚至直接在區塊鍊網絡上賺取收益率的原則。

However, to access these protocols and the DeFi platforms that power them, you’ll need a safe and reliable DeFi wallet. This is a specialized tool that connects you to smart contracts. That might sound complicated, but we’ll make sure it’s easy to digest. You’ll get the answer to “What is a defi wallet?” and learn how they manage your crypto assets.

但是，要訪問這些協議和為它們供電的Defi平台，您需要一個安全可靠的Defi錢包。這是一種將您與智能合約聯繫起來的專業工具。這聽起來可能很複雜，但是我們會確保它易於消化。您會得到“什麼是Defi錢包？”的答案。並了解他們如何管理您的加密資產。

What is a DeFi Wallet?

什麼是Defi錢包？

A DeFi wallet is a self-custody wallet, whether software or hardware, that stores your private keys and acts as a Web3 provider in compatible applications. This differs from a custodial wallet or exchange wallet, since a DeFi wallet app gives you complete control over your keys, so you are the only person who can authorize or deny transactions connected to that wallet.

Defi Wallet是一個自我顧客錢包，無論是軟件還是硬件，它都會存儲您的私鑰，並在兼容應用程序中充當Web3提供商。這與託管錢包或交換錢包不同，因為Defi Wallet應用程序可讓您完全控制鑰匙，因此您是唯一可以授權或拒絕連接到該錢包的交易的人。

Most of these wallets operate as a simple browser extension (one of the most popular being Metamask), mobile apps like Coinbase Wallet, and hardware wallets like Ledger and Trezor.

這些錢包中的大多數都是簡單的瀏覽器擴展程序（最受歡迎的元郵件之一），諸如Coinbase Wallet之類的移動應用程序以及Ledger和Trezor等硬件錢包。

When you visit a DeFi platform or interact with decentralized applications within the DeFi ecosystem, like a lending protocol, decentralized exchange, or yield farm, your wallet will prompt you to review and sign (authorize) transactions directly on-chain. This direct, instant connection to smart contracts allows you to move assets quickly, providing liquidity and earning rewards without being dependent on centralized intermediaries.

當您訪問Defi平台或與Defi生態系統中的分散應用程序進行交互時，例如貸款協議，分散交易所或收益農場時，您的錢包將提示您直接在鏈上進行查看和簽名（授權）交易。與智能合約的這種直接的即時連接使您可以快速移動資產，提供流動性並賺取獎勵，而無需依賴集中式中介機構。

How Does a DeFi Wallet Work?

Defi錢包如何工作？

A DeFi wallet app works more or less the same way as any other crypto wallet. It manages a pair of cryptographic “keys”, your public key, which is your wallet address, and your private key, which is your signature authority.

Defi Wallet應用程序的工作方式或多或少與其他任何加密錢包相同。它管理了一對密碼“鑰匙”，您的公共密鑰，即您的錢包地址和您的私鑰，這是您的簽名權限。

When you initiate or interact with a DeFi app that acts like swapping, the wallet creates a transaction payload and then prompts you to sign it with your key. This is typically just a single click or a tap, making it incredibly easy, but also introducing some risks.

當您啟動或與諸如交換之類的Defi應用程序進行交互時，錢包會創建事務有效載荷，然後提示您使用密鑰簽名。這通常只是單擊或抽頭，使其變得非常容易，但也引入了一些風險。

This signature is the blockchain proof that you own the transaction and that it’s authorized, without having to disclose your private keys. The wallet then broadcasts authorized transactions to the network, where nodes then validate it and execute the corresponding smart contract.

此簽名是區塊鏈證明您擁有該交易並已授權，而無需透露您的私鑰。然後，錢包將授權的交易廣播到網絡，然後在那裡節點驗證它並執行相應的智能合約。

Once the transaction is verified, the wallet then updates your balances and position. Beneath this process is a massive array of Web3 libraries and providers that help bridge your wallet to DeFi applications.

一旦驗證了交易，錢包就會更新您的餘額和位置。在此過程之下，是一系列龐大的Web3庫和提供商，可幫助您的錢包橋接到Defi應用程序。

What is a DeFi Wallet Used for?

Defi錢包用什麼？

A DeFi wallet is used to interact with smart contracts and decentralized protocols on a blockchain. It allows users to manage their crypto assets, authorize transactions, and participate in various DeFi services.

DEFI錢包用於與區塊鏈上的智能合約和分散協議進行交互。它允許用戶管理其加密資產，授權交易並參與各種Defi服務。

Here are some of the main uses of a DeFi wallet:

這是Defi錢包的一些主要用途：

Connecting to Decentralized Applications (DApps)

連接到分散應用程序（DAPP）

Decentralized applications, also known as DApps, are software programs that run on a decentralized network, such as a blockchain. They offer a wide range of financial services, including trading, lending, borrowing, yield farming, and more. To access these DApps, you need a DeFi wallet that can connect to the respective blockchain network and interact with the smart contracts powering the DApps.

分散的應用程序（也稱為DAPPS）是在分散網絡（例如區塊鏈）上運行的軟件程序。他們提供廣泛的金融服務，包括交易，貸款，借貸，產量耕種等。要訪問這些DAPP，您需要一個可以連接到相應區塊鍊網絡的Defi錢包，並與為DAPP提供動力的智能合約進行交互。

For example, if you want to use a decentralized exchange (DEX) like Uniswap or SushiSwap to swap tokens, you’ll need a DeFi wallet to authorize the transaction and interact with the DEX’s smart contract. Similarly, if you want to lend or borrow cryptocurrency on a protocol like Aave or Compound, your DeFi wallet will be used to deposit or withdraw funds and manage your lending/borrowing positions.

例如，如果您想使用分散的交易所（DEX）（例如uniswap或sushiswap）交換令牌，則需要一個defi錢包來授權交易並與DEX的智能合約進行交互。同樣，如果您想在AAVE或化合物等協議上借出或借用加密貨幣，則您的Defi錢包將用於存入或撤回資金並管理您的貸款/借貸職位。

Storing Private Keys and Securing Assets

存儲私鑰和確保資產

Crucially, a DeFi wallet is a self-custody wallet, meaning that you maintain complete control over your private keys. These keys are used to generate your public address, which is like your account number at a bank.

至關重要的是，Defi Callet是一個自我顧客錢包，這意味著您可以完全控制對私鑰。這些密鑰用於生成您的公共地址，就像您在銀行的帳號一樣。

In contrast, centralized exchanges or custodial wallets hold your private keys on your behalf, making them vulnerable to theft or fraud. When you use a DeFi wallet, you are the sole authorized party for any transactions outgoing from that wallet balance.

相比之下，集中的交易所或託管錢包代表您拿著私鑰，使其容易受到盜竊或欺詐的攻擊。當您使用Defi Wallet時，您是該錢包餘額外部的任何交易的唯一授權方。

This level of security is paramount in the decentralized finance space, where scams and exploits are unfortunately prevalent. A hardware wallet, like Ledger Nano S Plus or Trezor Model One, provides an additional layer of security by storing your private keys on a physical device that is not connected to the internet.

在分散的融資領域中，這種安全性至關重要，不幸的是，騙局和利用很普遍。硬件錢包，例如Ledger Nano S Plus或Trezor Model One，通過將私鑰存儲在未連接到Internet的物理設備上，從而提供了額外的安全性。

This makes it nearly impossible for hackers to steal your funds, even if they gain access to your computer or mobile device.

這幾乎使黑客無法訪問您的計算機或移動設備，也幾乎不可能竊取您的資金。
