FAQ’s
What is Underly?
Underly $UND is an infrastructure project for teams that want to deploy and operate their own appchains.
Underly acts as the deployment and operations layer beneath the Superchain, giving teams a cleaner way to launch Ethereum L2s, Optimism L3s, and Base L3s from one dashboard.
The platform is built to remove the infrastructure burden around rollup launches, including sequencers, batchers, proposers, RPCs, explorers, bridges, monitoring, logs, upgrades, artifacts, and developer configs.
Instead of spending months setting up chain infrastructure, teams can choose the chain type they need, configure the basics, review costs and readiness, deploy, and focus on the actual product.
Underly is built for the appchain future.
