Launching a layer and plans

From the launch page you choose a name, a slug (your RPC path), how fast blocks are made and the gas floor your users pay. A plan costs 2 HYPE for 30 days and is paid to the Hub contract on Elysium. Longer plans are multiples of 30 days.

Within minutes of payment the operator creates the rollup on Elysium through the Demiurge RollupCreator, funds the layer's batch poster and validator, stakes the validator's 0.01 WHYPE base stake, and boots the node. You get a chain id, a public RPC at /rpc/your-slug, an explorer page and a place in the gallery.

Where the plan payment goes

A small provisioning float is taken first, for the layer's own batch and assertion gas. What remains splits in two: half to the stakers of your layer (or the global stakers' pot if it has none), half to the treasury that keeps nodes running.

When a plan ends

A layer has 14 days of grace after its paid-until date. During that time deposits stay open and the layer keeps running. After that, the sequencer stops. The rollup state stays on Elysium, nothing is lost, and paying again restarts the layer where it left off. Users should withdraw before a layer's plan and grace run out; the docs chapter on security says what a stopped layer means for them.

The Commons

The Commons is a layer with no plan. It was created at launch and stays on, so there is always somewhere to deploy for free and the gallery is never empty.
