Midnight Indexer 4.0.2

Release notes

Release name

Version: 4.0.2
Date: 2026-04-23

[4.0.2] - 2026-04-23

⚠️ Requires an indexer reset when upgrading from 4.0.1 to 4.0.2

The paidFees correction (#1068) recomputes transaction fees for already-indexed data, so existing index state must be rebuilt. Reset the indexer and re-index from genesis on upgrade. Budget ~3–4 days for the re-index at mainnet/preprod scale.

🐛 Bug Fixes

• Correct paidFees computation (backport of #1031 and #1061) (#1068)

Audience
