No	Scenario	Pre-condition	Pre-condition check	Expected result	Expected result check	Covered By
1	eibc invariants	At least x amount of eIBC are finalized at least x amount of eIBC are pending at least one epoch has passed since first eIBC message (for rollapp packet deletion. Epoch by default in that case is 1hr)	✅	run crisis for the eibc module and pass successfully	✅	TestEIBCInvariant_EVM TestEIBCInvariant_Wasm
2	rollapp invariants	At least 2 rollapps are registered at least 1 is an evm rollapp at least 2 grace periods has passed a few states are in pending mode currently	✅	run crisis for the rollapp invariant and pass successfully	✅	TestRollappInvariant_EVM TestEIBCInvariant_Wasm
3	sequencer invariants	multiple sequencers registered per rollapp a few bonded, one unbonding and one bonded	✅	run crisis for the sequencer invariant and pass successfully	✅	TestSequencerInvariant_EVM TestSequencerInvariant_Wasm
