Validity Transactions

Submit transactions with onchain conditions, then let the sequencer include them only while those conditions are valid.

State-Aware InclusionThe sequencer evaluates current onchain state immediately before including a transaction.
Submit Before It Is ValidSign and submit intent now, then let it wait until its execution conditions are satisfied.
Storage ConditionsRequire contract storage values to match ranges or expected values at inclusion time.
Block Bounds & ExpiryConstrain execution to explicit block windows so stale transactions expire safely.
Condition-Aware OrderingTransactions follow priority fee ordering, but are deferred within a block until their validity criteria are satisfied.
No Keeper RequiredBuild intent-like flows from ordinary account transactions without a separate settlement contract.

Demos

Race the Agent

Submit a withdrawal before it is valid, then race a randomized onchain condition with an ordinary transaction sent by hand.

Conditional Swaps

Place a swap that waits for a target price, then lands or expires as a shared simulated market moves through its validity window.
