What Interlude is

Your contract stays on Monad. An engine runs the hot loop. Diffs settle back to the same address. Nothing is bridged.

Interlude is a real-time engine in front of Monad. You mark storage on your contract. A node runs those writes in milliseconds, with no gas after one signature. Every few seconds it commits the diffs back to the same address. Nothing is bridged.

You write the Solidity. ship takes it live. The SDK is how the frontend talks to the engine.

1. 01

   Delegate

   delegateAll() locks the marked slots on Monad. ship already sends this.

2. 02

   Execute

   The user signs once. Then session.send(fn, args) hits the engine. No popup, no gas.

3. 03

   Commit

   The node publishes diffs to the same contract. Monad is still the source of truth.

4. 04

   Undelegate

   When the session or partition is done, undelegate(partition) lifts the lock. Same address, settled state. Stake stays through the challenge window; then releaseStake frees it.
