[Unreleased]

Changed

  • Event schema versioning (#275): Every env.events().publish() call in the Fiat Bridge contract now includes EVENT_VERSION (currently 1, a u32) as the first topic element. Off-chain indexers can use this field to detect breaking schema changes and handle migrations gracefully.
    • Affected events: deploy_hash, deposit, rcpt_issd, withdraw, req_withdr, paused, unpaused, slippage, admin_action_queued, admin_action_executed, deny_add, deny_rem, heartbeat, nonce_inc, fee_accrue, fee_wdrw, rescue, quota_set, quota_reset, migration, batch_fail, batch_ok, cb_reset, cbtripped.
    • Updated existing test_withdrawal_quota_resets_after_window assertion to match the new topic order.
    • Added unit tests (test_event_version_deposit, test_event_version_request_withdrawal, test_event_version_deny_add_remove) asserting that EVENT_VERSION is the first topic for bridge-emitted events.
