Problem

Settlement ran through a third-party rail with opaque fees and multi-hour finality. Reconciliation consumed a full-time analyst.

Intervention

A custom ZK-rollup with an in-house indexer, reorg guard and automated reconciliation. Two independent audits before mainnet.

Outcome

$4M in annual settlement volume, 42ms p50 indexer reads, and zero critical findings across two audits — reconciliation is now automatic.
