Underly is one of those products that makes more sense the longer you think about where crypto is going.
Every serious app eventually hits the same wall.
Shared blockspace gets noisy.
Gas becomes unpredictable.
Infra becomes a distraction.
Teams spend more time managing RPCs, explorers, bridges, sequencers, configs, logs, upgrades, and monitoring than building the actual product.
The future is not one chain trying to host every game, agent network, marketplace, SocialFi app, DeFi protocol, launchpad, and consumer product.
The future is thousands of appchains, each with its own execution environment, its own economics, its own rules, and its own user experience.
Underly is the control plane for that shift.
Launch an Ethereum L2 when trust matters most.
Launch an Optimism L3 when you want Superchain alignment.
Launch a Base L3 when distribution, cost, and consumer access matter.
Same dashboard.
Same OP Stack foundation.
Deployment, RPC, explorer, bridge, logs, monitoring, artifacts, and operations handled underneath.
That is the part most people are still underestimating.
Appchains are not just about cheaper gas. They are about giving applications their own operating environment instead of forcing every product to fight for space on the same public chain.
Games need cheap actions.
AI agent networks need dedicated sequencing.
Social apps need low-cost interactions.
Marketplaces need branded rails.
Launchpads need repeatable deployment.
Enterprises need control, auditability, and clean exit paths.
Underly turns that into a system teams can actually use.
Not a pitch deck about modular infra.
Not another generic SaaS shell.
A real launch system for the Superchain appchain era.
$UND
Making L3 deployment frictionless expands Base’s surface area.
Every Base-settled L3 becomes another execution environment for apps, games, agents, SocialFi, marketplaces, and communities to build closer to the Base ecosystem.
Underly makes that path simple: deploy the chain, get RPC, explorer, bridge helper, and developer configs immediately after launch.
More Base L3s means more apps, more experiments, and more surface area for Base.@igoryuzo@brian_armstrong@base@bankrbot@coinbase
Underly deployment payments are now made in mainnet ETH.
Every chain launch has real costs behind it: parent-chain deployment transactions, RPC infrastructure, explorer hosting, bridge helper, logs, artifacts, monitoring, and ongoing service operations.
So even when users deploy a testnet chain, the deployment fee is paid in mainnet ETH.
Current pricing:
Testnet chain deployment: 1 ETH
Mainnet chain deployment: 2 ETH
This keeps Underly sustainable while giving teams a full launch environment, not just a chain ID.
Every deployment comes with HTTP RPC, WebSocket RPC, explorer, bridge helper, developer configs, and the infrastructure needed to test the chain immediately after launch.

Underly Base Sepolia L3 test deployment is live.
This chain is settling to Base Sepolia and now has the core launch stack attached: HTTP RPC, WebSocket RPC, explorer, and bridge helper.

This is an example of an Underly bridge for our deployed app chain. This is live https://t.co/pet68eBUC7
Underly bridges are built to let users test the viability of their deployed chains immediately after launch.
Once a chain goes live, teams need a simple way to move funds, test transactions, and confirm that the deployment works beyond just having an RPC or explorer.
We have deployed a mini version of the bridge for early testing, and the UI will be upgraded soon.
The goal is simple: every Underly chain should be usable right after deployment, not just technically live.
At just 100 testnet deployments and 25 mainnet deployments, Underly would generate 150 ETH in deployment revenue before counting monthly hosting, RPC, explorer, bridge helper, monitoring, support, custom domains, or upgrades.
The real business is not only launching chains. It is operating the infrastructure around them.
$UND is designed around two core functions: revshare and governance.
As Underly earns from deployments and ongoing infrastructure services, $UND holders and stakers earn in the revenue generated by the platform.
Governance gives the community a voice in how the ecosystem evolves, from supported deployment types to treasury decisions, fee models, and future infrastructure expansion.
The goal is simple: usage comes into Underly, revenue flows through to $UND holders, and governance lets the ecosystem help shape what Underly becomes.
Deployments create revenue.
Infrastructure creates recurring revenue.
$UND is the revshare and governance layer.
We are setting Underly deployment pricing at 1 ETH for testnets and 2 ETH for mainnets.
The reason is simple: launching a chain is not just creating a config file.
Every deployment needs parent-chain transactions, hosted infrastructure, RPC, explorer, bridge helper, monitoring, logs, artifacts, and ongoing operational support.
If teams want their own appchain, Underly gives them the full launch environment from day one.
Base-settled L3 deployment is now live on Underly.
Connect wallet, run the readiness checks, pay the deployment fee, and Underly handles the stack underneath: chain deployment, RPC, explorer, bridge helper, logs, artifacts, and developer configs.
Testnet launches are open now. The fee moves to 0.1 mainnet ETH soon because real deployments have real infrastructure and parent-chain costs.
You can now launch an L3 that settles to Base through Underly.
The flow is simple: connect wallet, pass the readiness checks, pay the deployment fee, and Underly handles the chain deployment underneath.
We are keeping testnet deployments open for early testers right now, but the launch fee is moving to 0.1 mainnet ETH soon.
It cannot stay free forever because every real deployment has costs: parent-chain transactions, infrastructure, RPC, explorer, bridge helper, monitoring, and hosted services.
So if you want to test launching your own Base-settled L3, now is the right time.
