Introducing LitVM: Litecoin’s ZK Omnichain

LitVM is Litecoin’s ZK omnichain designed as a zero-knowledge rollup (zkRollup) that integrates the Litecoin and Ethereum ecosystems, built for the Litecoin community. As an Ethereum Virtual Machine (EVM)-compatible chain, LitVM provides the Litecoin community with a secure, scalable, and high-performance platform for building Web3 applications. Supporting trustlessly-bridged Litecoin-native assets (LTC, LRC20 tokens, Runes, Ordinals — referred to herein as ‘Lordinals’ — and Charms) in addition to BTC, LitVM enables developers to innovate across payments, real-world assets (RWAs), decentralized finance (DeFi), non-fungible tokens (NFTs), gaming, and more. The integration of AggLayer provides interoperability, composability, and unified liquidity across integrated chains. By fostering interoperability with the broader ecosystem and strengthening ties with Bitcoin, LitVM aims to redefine Litecoin’s role in the modern Web3 landscape.

Litecoin’s Journey and Present Crossroads

Litecoin (LTC), launched in 2011 by Charlie Lee, emerged as a faster, cost-efficient alternative to Bitcoin, often dubbed the “silver to Bitcoin’s gold”. Utilizing a Scrypt-based proof-of-work mechanism, Litecoin boasts a 2.5-minute block time — four times faster than Bitcoin’s — enabling quick confirmations and fees typically below $0.01. This has positioned Litecoin as a leader in everyday payments and microtransactions, with integrations in platforms like BitPay and Travala. Its development emphasizes simplicity, security, privacy, and decentralization, mirroring Bitcoin’s ethos. Key upgrades include Segregated Witness (SegWit) in 2017 for improved scalability and MimbleWimble Extension Blocks (MWEB) in 2022 for optional privacy, reinforcing Litecoin’s role as a testing ground for Bitcoin-compatible innovations. With a market cap over $6 billion and 300,000 daily active addresses as of May 2025, Litecoin maintains a prominent position in the rankings.

However, the rise of smart contract platforms like Ethereum has exposed limitations in Litecoin’s Layer-1 (L1) design. Lacking native smart contract functionality, Litecoin has been unable to support complex Web3 use cases, restricting its participation in high-growth sectors. While Litecoin’s focus on payment efficiency remains a strength, the absence of a scalable Layer-2 (L2) solution has hindered its ability to compete in the rapidly evolving Web3 ecosystem, where programmability and interoperability are paramount.

Empowering Litecoin’s Evolution

Without an L2, Litecoin risks obsolescence in a Web3 era prioritizing scalability and programmability. Litecoin’s lack of interoperability and composability poses similar risks in the future-facing Web3 industry. LitVM, a zkRollup-based omnichain, addresses these needs, preserving Litecoin’s strengths while integrating advanced Web3 capabilities and cross-chain interoperability.

LitVM is an EVM-compatible omnichain for Litecoin, leveraging zkRollup technology to enable scalable, secure, and cost-efficient Web3 applications. It processes thousands of transactions off-chain, anchoring validity to Litecoin via ZK proofs, ensuring efficiency and security. With dual settlement on Ethereum, LitVM taps into Ethereum’s liquidity and vast developer base while preserving Litecoin’s fast, low-cost transactions. Its objectives include:

• Scalability: Achieve thousands of TPS with sub-cent fees, compared to Litecoin’s 50 transactions-per-second (TPS) on the L1 and Ethereum’s high gas costs.
• Programmability: Support smart contracts, RWAs, DeFi, NFTs, and gaming dApps using familiar EVM tools (e.g. Solidity, Hardhat).
• Privacy: Build on Litecoin’s MWEB and ZK cryptography for shielded transactions and new use cases.
• Ecosystem Growth: Encourage developer and user adoption for the broader Litecoin ecosystem through grants, incentives and hackathons to foster a vibrant and cutting-edge application landscape.
• Interoperability: Bridge Litecoin with Ethereum, Bitcoin and beyond via BitcoinOS and AggLayer for unified liquidity and cross-chain dApps.
• Innovation: Facilitate the creation of innovative new applications and use cases by combining Litecoin’s vibrant community with LitVM’s advanced tech stack and EVM compatibility.

LitVM’s full EVM compatibility ensures a seamless development experience, enabling developers to write smart contracts in Solidity, Vyper, or other EVM-compatible languages. EVM compatibility positions LitVM as a developer-friendly platform, bridging Litecoin’s payment-focused community with Ethereum’s 10,000+ active developer ecosystem.

LitVM addresses Litecoin’s lack of smart contract support and interoperability, positioning it as a Web3 hub complementary to Bitcoin and Ethereum.

Future-Proof Tech Stack

LitVM leverages zkRollup technology to deliver scalable, secure, and interoperable Web3 applications. It processes thousands of TPS off-chain, using zkSNARKs for compact proofs verified on Litecoin’s L1. Dual settlement with Ethereum taps into its $400 billion ecosystem, while AggLayer unifies liquidity across chains. LitVM supports Litecoin-native assets (LTC, LRC20 tokens, Runes, Lordinals, and soon Charms), Ethereum assets, and BTC, enabling cross-chain dApps for payments, RWAs, DeFi, and beyond.

The key components making LitVM possible are BitcoinOS, Polygon CDK and AggLayer.

BitcoinOS

BitcoinOS (BOS) is a smart contract operating system originally developed for Bitcoin, and adapted for Litecoin to enable scalable zkRollup chains with trustless bridging and programmability. Successfully demonstrated on Bitcoin in July 2024 (block 853626), BOS leverages advanced ZK cryptography to execute complex computations off-chain while anchoring results to the L1 (Litecoin in the case of LitVM).

BOS’s adaptation for LitVM leverages Litecoin’s faster 2.5-minute block times and Scrypt-based consensus, optimizing for rapid finality and low-cost settlement. By integrating BOS, LitVM enables smart contract functionality for trustlessly bridged Litecoin-native assets in addition to BTC. In the future, BitcoinOS’ new Charms tokens can also be integrated with LitVM.

Polygon CDK/Erigon

Polygon’s Chain Development Kit (CDK) and CDK-Erigon form the backbone of LitVM’s Ethereum-side operations, providing a scalable, EVM-compatible zkRollup framework. Backed by Polygon’s $1.5 billion investment in ZK research, this stack ensures seamless integration with Ethereum’s ecosystem while maintaining high performance and customization (such as LTC as gas).

CDK-Erigon’s optimizations, including fast-sync protocols and memory-efficient data structures, enable LitVM to process thousands of TPS at sub-cent fees, making it ideal for all retail and enterprise use cases.

AggLayer

AggLayer, developed by Polygon Labs, is a decentralized protocol that enhances LitVM’s interoperability by unifying liquidity and state across a diverse ecosystem of blockchains, including EVM-compatible chains like Ethereum and Polygon, as well as non-EVM networks. It leverages ZK cryptography to ensure secure, trustless interactions, positioning LitVM as a future-proof platform for Web3 innovation.

By integrating AggLayer, LitVM supports cross-chain dApps that leverage Litecoin’s global adoption alongside the diverse features of AggLayer’s network, such as unified DeFi protocols or RWA platforms spanning multiple chains. This enhances LitVM’s scalability and reach, fostering a connected Web3 environment and ensuring the Litecoin ecosystem remains competitive as blockchain technology evolves.
