Mevlog Rs

Mevlog Rs is a Rust command-line indexer that downloads raw EVM chain data from an RPC endpoint, stores it in a local SQLite database and lets users analyze that data with read-only SQL. Its EVM-specific SQLite helpers support 256-bit math, ERC-20 decoding, value formatting and ENS resolution.

Practical overview

When it fits

Use Mevlog when you want to download EVM data from an RPC endpoint and perform SQL analysis against a local SQLite cache, including repeated queries over the same block ranges.

Who it is for

  • Developers and analysts who want local SQL access to EVM chain data.
  • Users building repeatable transaction-cost or token-activity analyses over selected block ranges.

Documented uses

  • Fetch and inspect transactions from an Ethereum block.
  • Query cached EVM data with read-only SQL.
  • Rank transactions by gas cost and format the result in ETH.
  • Decode ERC-20 data and apply EVM-specific calculations using SQLite helpers.
Before you choose

Requirements & limits

The project is open-source and its README describes it as MIT-licensed. The documented CLI installation uses Cargo. The README lists Linux, macOS and Windows as platforms and links to a live SQL demo.

  • The data workflow is local: chain data is downloaded from an RPC endpoint and stored in SQLite.
  • The interface is a command-line tool, and analysis uses read-only SQL.
  • Mevlog includes EVM-specific helpers, including 256-bit arithmetic, token decoding and ETH, gwei and USD formatting.
  • The README says an RPC endpoint can be detected through ChainList without additional configuration; users can also use an RPC endpoint as the data source.
  • The first run downloads and indexes a signatures database.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Mevlog and query Ethereum block transactions

Install the CLI with Cargo and display transactions from the latest Ethereum mainnet block.

Before you start

  • Cargo
  • An RPC endpoint; the README says Mevlog can detect one through ChainList without additional configuration.

Steps

  1. Install with the command below.

    Documented command
    cargo install mevlog --locked

  2. Run mevlog block-txs -b latest --chain-id=1 to fetch and display transactions from the latest Ethereum mainnet block.

Expected outcome

The CLI displays transactions from the selected latest Ethereum mainnet block.

Guide limitations

  • On the first run, a signatures database is downloaded and indexed; the README estimates this can take up to about one minute.

Query transaction costs in a block range

Run a read-only SQL query that ranks transactions by gas cost and formats the result in ETH.

Before you start

  • Mevlog installed and access to an RPC endpoint.
  • An Ethereum block range to query.

Steps

  1. Run the documented mevlog query command with the chosen block range and --chain-id=1.

  2. Use SQL to multiply gas_used by effective_gas_price, sort by that value and limit the results.

  3. Format the cost with format_ether.

Expected outcome

The query returns transaction hashes and formatted ETH costs for the selected range.

Guide limitations

  • The query command runs read-only SQL against data in the local database.
