Precompile functions usage report

[natanasow]

Problem

We should investigate how many times precompile functions are used in the current mainnet contracts, and how many transactions have interacted with the current contracts.

Solution

Disassemble contracts bytecode to find out calls to the 0x167, fetch the contract results for these contracts, and get the calls generated in the fetched transactions.

First part:

• fetch all contracts on mainnet
• disassemble their bytecode, look up for call, staticcall, delegatecall against 0x167 and list how many times each precompile function is used

Second part:

• fetch all transactions that have interacted with these contracts
• get their calls via MAPI /contracts/results/<tx_hash>/actions
• humanize the data and add it to the report
