DeFiPy 簡介：用於分析 DeFi 協定的終極工具套件

DeFiPy 是一款用於 DeFi 分析的綜合 Python 套件，無縫整合了主要協議以進行穩健的分析。透過模組化設計，研究人員和分析師可以使用專用軟體包按協議隔離分析。 DeFiPy 作為一種定量審計協議而開發，解決了向代幣化經濟和 DeFi 主導地位過渡時對標準化測試框架的需求。該套件支援基於模擬的測試，使 Web3 設計人員能夠對數以萬計的模擬交易進行嚴格的基準測試。基本用法包括透過通用介面建立協議，以 Uniswap、Balancer 和 Stableswap 範例進行示範。 DeFiPy 還提供即時紙本交易工具（DeFiPy-0x Quant Terminal），可根據 0x Price API 的即時礦池資料視覺化相關活動和參數。該套件正在不斷發展，即將發布的版本包括 Uniswap V3 重構、歷史價格數據整合和流動性樹分析。

Introducing DeFiPy: A Comprehensive Python Suite for DeFi Analytics

DeFiPy 簡介：用於 DeFi 分析的綜合 Python 套件

The Dawn of a Tokenized Economy

代幣化經濟的黎明

The financial landscape is undergoing a pivotal transformation towards a tokenized economy, as eloquently articulated by Bettina Warburg in her TED talk. DeFi, the decentralized finance ecosystem, is poised to revolutionize the finance industry, mirroring the digital transformation that the internet brought to information dissemination.

正如 Bettina Warburg 在 TED 演講中雄辯地闡述的那樣，金融格局正在經歷向代幣化經濟的關鍵轉型。去中心化金融生態系統 DeFi 可望徹底改變金融業，反映出網路為資訊傳播帶來的數位轉型。

The Imperative for DeFi Analytics

DeFi 分析勢在必行

As DeFi protocols become increasingly complex, the need for robust and standardized quantitative auditing grows ever more pressing. Traditional finance relies on well-established protocols for assessing risk and ensuring the integrity of financial systems. The DeFi ecosystem, however, lacks such standardized frameworks.

隨著 DeFi 協議變得越來越複雜，對穩健且標準化的定量審計的需求變得越來越迫切。傳統金融依賴完善的協議來評估風險並確保金融體系的完整性。然而，DeFi 生態系統缺乏這樣的標準化框架。

To address this critical gap, DeFiPy emerges as the open-source standard for building tooling to rigorously test and analyze DeFi protocols. By providing a comprehensive suite of tools for simulating and modeling DeFi systems, DeFiPy empowers researchers and practitioners to perform thorough quantitative audits, ensuring the safety and reliability of these protocols.

為了解決這一關鍵差距，DeFiPy 作為開源標準應運而生，用於建立嚴格測試和分析 DeFi 協議的工具。透過提供一整套用於模擬和建模 DeFi 系統的工具，DeFiPy 使研究人員和從業者能夠進行徹底的定量審計，確保這些協議的安全性和可靠性。

Basic Usage

基本用法

DeFiPy offers a unified interface across all supported protocols:

DeFiPy 為所有支援的協定提供統一的介面：

• ERC20: Represents mock ERC20 tokens used in all protocol simulations.
• ExchangeData: Data class for initializing the parameters of mock exchanges.
• IExchange: An abstract base class for all DeFiPy protocol exchanges, providing common functionality such as liquidity management and trading.
• IExchangeFactory: A factory class for creating and deploying IExchange instances.

A Hands-On Example: Uniswap Simulation

ERC20：代表所有協議模擬中使用的模擬ERC20代幣。 ：工廠用於建立和部署 IExchange 實例的類別。

Uniswap, a prominent Automated Market Maker (AMM), employs a constant product trading mechanism. To simulate a Uniswap liquidity pool (LP), follow these steps:

Uniswap 是一家著名的自動做市商 (AMM)，採用恆定的產品交易機制。若要模擬 Uniswap 流動性池 (LP)，請依照下列步驟操作：

from defipy import *
來自 defipy 導入 *

user_nm = 'user_intro'
user_nm = '使用者簡介'
eth_amount = 1000
以太幣數量 = 1000
dai_amount = 1000000
dai_金額 = 1000000

dai = ERC20("DAI", "0x01")
dai = ERC20("DAI", "0x01")
eth = ERC20("ETH", "0x02")
eth = ERC20("ETH", "0x02")

factory = UniswapFactory("ETH pool factory", "0x")
factory = UniswapFactory("ETH池工廠", "0x")
exchg_data = UniswapExchangeData(tkn0 = eth, tkn1 = dai, symbol="LP", address="0x11")
exchg_data = UniswapExchangeData(tkn0 = eth, tkn1 = dai, 符號=“LP”, 位址=“0x11”)

lp = factory.deploy(exchg_data)
lp = 工廠.deploy(exchg_data)

lp.add_liquidity("user0", eth_amount, dai_amount, eth_amount, dai_amount)
lp.add_liquidity("user0", eth_amount, dai_amount, eth_amount, dai_amount)

lp.summary()

Example Output:

lp.summary()範例輸出：

Exchange ETH-DAI (LP)
兌換 ETH-DAI (LP)
Reserves: ETH = 1000, DAI = 1000000
儲備金：ETH = 1000，DAI = 1000000

Advanced Protocol Simulations: Balancer and Stableswap

流動性：31622.776601683792高階協定模擬：Balancer 和 Stableswap

Balancer extends Uniswap's constant product mechanism to handle multi-asset pools, introducing the concept of weighted pools. Stableswap specializes in implementing Composable Stable Pools, ideal for stablecoin liquidity management.

Balancer 擴展了 Uniswap 的恆定乘積機制來處理多元資產池，引入了加權池的概念。 Stableswap 專注於實施可組合穩定池，是穩定幣流動性管理的理想選擇。
