ANECDOTE

From Spreadsheet To Radical-Transparency Platform

  • Bartek built L2BEAT after researching rollups for MakerDAO and publishing a spreadsheet that became a public resource.
  • That spreadsheet grew into an automated platform that now monitors hundreds of L2s and flags changes daily.
INSIGHT

Automation Enables Trustworthy L2 Ratings

  • L2BEAT enforces radical transparency by verifying every claim on-chain and automating monitoring for protocol changes.
  • Automated detection lets them mark systems 'under review' immediately when critical parameters change.
ADVICE

Verify Claims And Watch Upgrades Daily

  • Verify L2 claims on-chain rather than trusting marketing or docs; use L2BEAT's published links and proofs.
  • Monitor protocol updates since small upgrades can materially change trust and ratings overnight.
