Pontem announces Lumio – the first L2 to support both EVM and Move VM
Table of Contents
We’ve been working on it in secret for months, and we’re finally ready to reveal it: Lumio, the first-ever rollup that brings together the best of Ethereum and Aptos. While it’s in the closed testing stage for now, we can already share all the key info with you.
What is Lumio?
Lumio is a new optimistic rollup built by Pontem Network. What makes it different from all other rollups (Optimism, Arbitrum, etc.) is that it supports both Ethereum Virtual Machine and Move VM, the virtual machine used by Aptos and in the end state will leverage Aptos to process transactions that settle on Ethereum.
The name ‘Lumio’ is connected to Latin “lumen”, which means light. We were thinking of the speed of light, since our L2 makes any dApps for Ethereum run faster.
To build Lumio, we used the OP Stack - an open-source set of development tools released by the Optimism Collective. Anyone can leverage it to build a scalable and fast optimistic rollup.
The OP Stack already powers the Optimism mainnet. It will also serve as the base of Optimism Superchain – a future network of interconnected L2s. Lumio uses a Rust implementation of the OP Stack, with the Magi client developed by a16z and Reth (Rust Ethereum), the execution layer (full node) developed by Paradigm.
The advantage of this solution is that it makes it much easier to integrate Move VM, since Move itself is based on Rust. Move itself is a secure and efficient smart contract language than Solidity.
Lumio currently settles on Ethereum Sepolia and uses ETH as its gas currency. But we designed it as a framework to be both execution- and settlement-layer agnostic, so in theory you can adjust Lumio to work as an L2 for various blockchains and virtual machines. For example, it can be integrated with Aptos, Optimism, Celestia, etc.
What we mean by this is that at present, all transactions on Lumio are rolled up into batches and submitted to Ethereum for final settlement. But there can also be an implementation of Lumio where transaction batches are submitted to Aptos instead, or even to another Ethereum rollup.
With Lumio, developers can build dApps using both Solidity and the Move stack. It’s even possible to enable Cross VM calls to deploy multichain applications. Our vision is to interconnect liquidity on all supported chains.
Important warning! Don’t believe anyone who tries to promote or sell you any “Lumio tokens”, “PONT tokens” etc. Any such offer is a scam. Lumio doesn’t have its own token: it uses bridged ETH.
Lumio rollout schedule
Pontem L2 isn’t open to the general public yet. The rollout will happen in several waves, where the first wave will include up to 1,000 users:
- Pontem Pirates & Dark Ages holders - 100 random addresses and 100 addresses selected on the FCFS basis. Go to our X page and drop your Ethereum and Aptos address in the comments to the thread for your chance to get selected.
- Liquidswap users - 100 random and 100 FCFS;
- Members of Aptos OG communities like Aptos Monkeys, Bruh Bears, and Mavericks - 200 addresses in total (100 random, 100 FCFS);
- Pontem partners (early investors, KOLs, institutionals, integrators, etc..)
- New OGs - we will have opportunities for new users to join as well. You can start by dropping your Ethereum and Aptos address in the comments to the thread on Twitter.
For Wave 2 and, please join the waitlist on lumio.io.
Lumio is already live on Sepolia – the new default Ethereum testnet that replaced Goerli. The following wallets support our L2:
- Pontem Wallet: both the EVM and the Move VM parts;
- MetaMask: EVM part only;
- Petra: EVM part only.
Lumio in action
In preparation for broader community testing, we’ll give you a sneak peek at what can be done with Lumio.
- Claiming gas coins: for the EVM side of things, we’ve created a special interface that distributes testnet ETH to whitelisted addresses. On Move VM, there is a faucet in Pontem Wallet itself that distributes NAT – just another ticker for testnet ETH that Lumio uses for gas. NAT doesn’t have any real-world value, and we don’t plan to release it on the mainnet.
- Bridging: users need to have ETH on Sepolia in order to send it to Lumio. It can be obtained from various online faucets.
- Swapping: Liquidswap supports Lumio, so that testers can make swaps or add liquidity to pools straight away. Liquidswap for Lumio features a faucet where testers can claim testnet BTC and USDT for swaps. Of course, since these are testnet pools, the prices can differ wildly from real-world prices. This is fine, since testnet coins are valueless anyway.
- Explorer: Lumio already has its block explorer where users can track the transactions.
We will announce the mechanics of alpha tester selection for the next stages soon on our X page. At every stage, we’ll use the feedback to polish Pontem’s L2. In the next few months, Lumio should become available to all of you – stay tuned!
