Public Reference

Migration Event Reference

Migration is not a logs-only path. The public implementation uses lifecycle detection from logs and resolves the final event from the parsed transaction of that same migration transaction.

Client guidance

Implementation rule

Lifecycle logs are only the trigger. The final migration event is derived from the current parsed transaction, without historical cache enrichment.

Safe parsing rule

Read pool and poolCreatedBy together, and do not assume every migration family exposes the same extra economics or token metadata.
