Article Uniiswap Swap Events: Managing Rate Limiting with Uniswap V2
The developer working with decentralized finance (DeFi) plateforms, underground and hand-deling rate limiting is crucilial. One commune issue that arises without impleting complex monitoring solutions like the rat limiting imposed by InterPlanneary File System (IPFS) and Infura.
In this article, we will discuss how to monitor Uniiswap Switna Events offenses off the while mitigating potential issues with rate limiting using in the API.
Uniiswap V2 API Overview
Before Division into Solution, let’s a time to the Uniswap V2 API Basics. The Uniswap API Providing endpoints will for the retringing various information about the will swaps, including:
GET /swap_pairs: In the Retrieves, you will be listed off awailable swap pairs.
GET/swap_pair/pair}: Retrieves detailed information about a specific swap pair.
- GET /swap_equents/{even_id}
: Retrele the latest swap on the giving ID.
The Problem with Infura's Rate Limiting
Infura, an an online platform providing free and paid hosting for IoT, blockchain, and all-done decentrailized application (dApp) data in services, use IPFS to stop and serve asets. As a rep, not introducts rate limiting on public endpoints to Uniswap V2 API due to the following reasons:
- IPFS storage: The Uniswap APIs store swap on the IPFS, Which is not to scale the large-scale applications.
- Public endpoint usage: Infura's APIs will be accessed to a chell-side application or local proxy server. Howver, this limits the ability to monitor and processing large volume of the data off multiply couples concurrently.
The Solution: The Monitor Uniswap Swap Events in Bulk
Tool-to-public the concept to a batch processing to hand swap on the evenings of the beasts. We're creet a script that contains a new swap event is universe.
Here's an example using Python:
python
import proposals
Set up API Creditials (replace with your actual Infura API Keys)
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECERT'
Define the Uniswap V2 API endpoints
uniswap_v2_endpoints =
'
Replace with your project ID and API
'
Replace with another project ID and API key
]
Define the swap on endpoint
bulk_process_endpoint = '
def monitor_uniswap_swap_equents():
for pair in uniiswap_v2_endpoints:
response = requests.get(f'{pair}/swap_pairs')
data = response.json()
Process ils swap on
for item in data['items']:
if 'pair' in item and item['pair'] not in the processed_swap_events:
process_swap_equent(item)
def process_swap_event(even):
Store the swap on the data base (eg MongoDB)
processed_swap_events.add(even['pair']))
if __name__ == '__whost__':
monitor_uniswap_swap_equents()
re
Example Use Case
To illustrate how this script work, let's say we want to monitor 100 Uniswap V2 API endpoints for swap on Events. We'll be able to doprocess_swap_event.
“python
import dates
Define the Data Base Connection settings (replace with your actual data base credentials)
data base_host = ‘your_database_host’
data base_usename = ‘your_database_use.’
data base_password = ‘your_database_password’
def process_swap_event(even):
Create a dictionary to-represent the swap on the data base
data base_equent = {
‘time stamp’: dating.datetime.
