README

Substreams EVM Precompiles Popularity

This project leverages Substreams to calculate the popularity of Ethereum precompiled contracts from call data.

Overview

  • Processes Ethereum call events using Substreams.
  • Counts and maps occurrences of precompiles.
  • Outputs results using Protocol Buffers.

Getting Started

  1. Ensure the Rust toolchain is installed.
  2. Build the project: cargo build --release.
  3. Deploy the WASM binary as specified in the Substreams configuration.

ethcommon:all_calls

`all_calls` gives you all the calls in a block (including internal calls), with basic block hash/number/timestamp and transaction hash

Output

sf.substreams.ethereum.v1.Calls

Inputs

sf.ethereum.type.v2.Block
map

ethcommon:filtered_calls

`filtered_calls` reads from `all_calls` and applies a filter on the called contract, the caller and the method 4-bytes signature Supported operators are: logical or `||`, logical and `&&` and parenthesis: `()` Addresses to match must be written as 0x-prefixed hexadecimal, lowercase, prefixed by `call_to:` or `call_from:`, methods by `call_method:`. Example: `(call_to:0x1234... || call_from:0x1234...) && call_method:0xdeadbeef...`

Output

sf.substreams.ethereum.v1.Calls

Inputs

paramsethcommon:all_calls
blockIndex

ethcommon:index_calls

`index_calls` sets the following keys on the block: * Call contract call_to:0x0123456789abcdef0123456789abcdef01234567 (contract address in hex, prefixed by 0x) * Caller call_from:0x0123456789abcdef0123456789abcdef01234567 (caller address in hex, prefixed by 0x) * Call method call_method:0x01234567 (4 bytes of method signature in hex, prefixed by 0x)

Output

sf.substreams.index.v1.Keys

Inputs

ethcommon:all_calls
