Practical overview

When it fits

Use it when you already have a JSONL export and want a local, whole-snapshot view of rent-exempt status and lamport concentration.

Who it is for

  • Solana program and account operators reviewing storage-bond balances.
  • Developers who need to inspect captured account snapshots for underfunded accounts or balance distribution.

Documented uses

  • Find accounts below a rent-exempt minimum calculated at a selected lamports-per-byte rate.
  • Summarize locked bonds, deficits, observed balances and closure-related reclaimable amounts.
  • See how lamports are distributed across data-size bands and account owners.
  • Review malformed JSONL records by line number without losing the rest of the analysis.
Before you choose

Requirements & limits

The Python core runs with the standard library; the repository also documents installation of a console script with pip. The public repository specifies the MIT license.

  • Input must be a JSONL account export; the documented CLI analyzes supplied snapshots rather than fetching live data.
  • The rent-exempt calculation uses a chosen lamports-per-byte rate.
  • Reports are available as line-oriented text or JSON with fixed field names.
  • Executable program accounts appear in status counts but are excluded from bands and locked totals.
  • A TypeScript verifier provides a second implementation for cross-checking rules; the primary tool is the Python CLI.

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

Run an audit on a JSONL snapshot

Generate a text report of rent-exempt status and balance distribution from a captured account snapshot.

Before you start

  • Python
  • A JSONL export of Solana accounts

Steps

  1. From the repository, set PYTHONPATH=src.

  2. Run python -m lamportlens audit followed by the snapshot file path.

Expected outcome

A text report classifies accounts and summarizes bonds, deficits, balances, data-size bands, owners and parse errors.

Guide limitations

  • The tool analyzes a provided snapshot; this command does not fetch live account data.
