uniswap-fetcher-rs 0.1.9

A Rust-based library to fetch and decode Uniswap V3 pool events, designed to be used as a Python module.

Uniswap Fetcher

Uniswap Fetcher is a Rust-based library that provides functionalities to fetch and decode Uniswap V3 pool events. It is designed to be used as a Python module using PyO3.

Features

• Fetch pool events by token pairs within a specified block range.
• Fetch pool events by token pairs within a specified time range.
• Fetch pool created events between two timestamps.
• Get block number range for a given timestamp range.

Prerequisites

• Rust and Cargo: Install from rustup.rs
• Python 3.10 or higher
• An Ethereum node RPC URL

Installation

1. Clone the repository:

   git clone https://github.com/nestlest/uniswap-fetcher-rs.git
   cd uniswap-fetcher-rs
   

2. Build the Python module:

   maturin develop
   

   This will build the Rust code and install the Python module locally.

Usage

Python

from uniswap_fetcher_rs import UniswapFetcher

# Initialize the fetcher with the RPC URL
fetcher = UniswapFetcher("http://localhost:8545")

# Define token pairs and block range
token_pairs = [("0xaea46a60368a7bd060eec7df8cba43b7ef41ad85", "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2", 3000)]
from_block = 12345678
to_block = 12345778

# Fetch pool events by token pairs
events = fetcher.get_pool_events_by_token_pairs(token_pairs, from_block, to_block)
print(events)

# Define time range
start_timestamp = 1633046400  # Example start timestamp
end_timestamp = 1633132800    # Example end timestamp

# Fetch pool data by token pairs within the specified time range
pool_data = fetcher.fetch_pool_data(token_pairs, start_timestamp, end_timestamp)
print(pool_data)

# Fetch pool created events between two timestamps
pool_created_events = fetcher.get_pool_created_events_between_two_timestamps(start_timestamp, end_timestamp)
print(pool_created_events)

To use the library directly in Rust, you can call the asynchronous functions provided in the lib.rs file.

Testing

To run the tests, use the following command:

cargo test
