Solana Commitment Levels in Production: Reconcile Confirmed and Finalized State

Mixing processed, confirmed, and finalized reads can create phantom balances and duplicate actions.

Model the failure correctly

Attach slot, block hash, provider, and commitment provenance to every observation.

Collect evidence

Keep tentative observations separate from canonical accounting and promote them only after the required confidence boundary.

Build the control path

Persist an append-only journal so forked observations can be reversed deterministically.

Handle edge cases

Use context slots and reject unexplained state regressions from lagging providers.

Recovery procedure

After reconnect, verify lineage, backfill the gap, deduplicate, and only then reopen the live stream.

Production metrics

Let signals use lower latency state while customer balances and durable PnL use finalized state.
