ChainRepro
For DeFi lending and vault protocols

Know whether your liquidations and keeper jobs actually get done.

ChainRepro checks the real economics behind your protocol's incentives: which positions are too small to liquidate after gas, how many bots actually compete, and where rewards fail to cover costs. Every number is reconciled from on-chain data.

How we test

Most on-chain profit claims fall apart once every cost is counted. These rules apply to every report we publish or deliver.

  1. Freeze the question first. The question and the cases are fixed before any analysis, and every case is reported, including losses and failures.
  2. Reconcile from raw balances. Results come from actual balance changes, with exact integer amounts, never from quotes or estimates.
  3. Count every cost. Gas, priority fees, tips, auction payments, flash-loan fees and failed attempts.
  4. Separate what happened from what might. Historical observation, our simulation and actual settlement are always labelled and never mixed.
  5. Missing data stays missing. Unknown values are reported as not measured, never as zero, and we never project income from a few winners.
  6. Publish the evidence. Transaction links, data and scripts, so anyone can check the result.
