DefiLlama Scraper

This project queries the Llama.fi API to retrieve data on the Total Value Locked (TVL) for various blockchains and DeFi protocols. It then plots graphs to visualize the TVL and fee distribution.

Function	Description
get_top_n_blockchains_by_tvl()	Retrieves the top n blockchains by TVL
tvl_change()	Calculates the change in TVL for a list of blockchains over a period of time
top_n_protocols_for_chain()	Retrieves the top n protocols by TVL for a specified chain
calculate_annualized_fee_data()	Calculates the annualized fee data for a list of protocols

Example Usage

python

top_10_blockchains = get_top_n_blockchains_by_tvl(top_n=10)

chain_list = tvl_change(chain_list, "01-01-2023", "30-06-2023")

top_10_Arbitrum_protocols, chain = top_n_protocols_for_chain("Arbitrum", 10)

annualized_fee_data = calculate_annualized_fee_data(protocol_list, chain)

Visualizations

The script generates several matplotlib plots:

TVL by chain
Change in TVL by chain
TVL by protocol
Annualized fees by protocol
