Lumio on Optimism Canary Mainnet

A Gateway to the Optimism Superchain

SuperLumio (сanary mainnet) marks the initial phase of the Lumio Layer 2 on the Optimism Superchain, launched as a pure Ethereum Virtual Machine fork with the support of Conduit technology. This platform is designed to serve as a testnet-in-production, akin to Kusama for Polkadot, allowing for active engagement, TVL growth, and project launches. The foundation of Lumio on Optimism paves the way for future releases to introduce a cross-VM heterogeneous block space, expanding its capabilities. In anticipation of future developments, Lumio on Optimism's roadmap includes the integration of both Move VM and SVM into the current mainnet implementation that is using EVM only.

Currently, Lumio on Optimism employs a centralized sequencer for transaction processing (like any other OP L2s), with plans to adopt a shared sequencer model. This transition towards a shared sequencer across the Optimism chains is a crucial step towards achieving greater security and interoperability within the ecosystem.

Importantly, Lumio on Optimism has been deployed on the Ethereum mainnet, operating with real assets, which sets it apart from traditional testnets. Users and developers engaging with Lumio on Optimism should be aware of its real-stakes environment.

Other wallets

You can do the same with other EVM based wallets.

Additionally, support for the Pontem wallet is on the horizon, further enhancing accessibility and user experience right from the start.

Bridge

The bridging process can take anywhere from 1 minute to 30 minutes. Please plan accordingly.

Lumio on Optimism enables users to deposit ETH and other tokens, such as USDC, USDT, and more, from the Ethereum L1 mainnet. This can be accomplished through the native L1 to L2 bridge.

Currently supported assets: ETH, USDC, USDT, Pepe.

Our dashboard is currently operating in silent mode, meticulously recording all user actions on the L2, including deposits and transfers. With the upcoming launch of DApps, such as Narswap, we will soon expand our monitoring to cover swaps, liquidity provisions, and more.

L2

The deployment addresses for L2 contracts are consistent across the entire Optimism stack. You can find these addresses as constants in the Optimism repository.

Fees

The fee model is akin to Optimism's, based on the Data Availability (DA) costs of transactions and execution expenses. For more details on L2 fees, please refer to our further documentation.

With the recent update to span batches, fees have become relatively more affordable. Moreover, the impending integration of ProtoDankSharding promises to further reduce costs once activated on SuperLumio
