FAQ

Find answers to common questions about LitVM, its technology, and how to get started.

General

What is LitVM?

LitVM (Litecoin Virtual Machine) is Litecoin's first trustless EVM rollup. It's an EVM-compatible smart contract platform built on Arbitrum Orbit and powered by BitcoinOS technology, enabling Web3 functionality such as Litecoin yield markets, RWA platforms, DeFi, NFTs, and programmable applications while inheriting Litecoin's proof-of-work security.

Is LitVM endorsed by the Litecoin Foundation?

Yes. LitVM is officially endorsed by the Litecoin Foundation, making it the first EVM Litecoin rollup with official community backing.

When will LitVM launch?

  • Testnet: Q1 2026

  • Token Generation Event (TGE): Following testnet

  • Mainnet: After TGE and security audits

Technology

How does LitVM work?

LitVM is an Arbitrum Orbit chain (rollup) that:

  1. Executes smart contracts using Arbitrum Nitro (EVM-compatible)

  2. Uses Succinct zkVM to generate validity proofs

  3. Bridges LTC trustlessly via BitcoinOS Grail bridge

  4. Bridges ETH and ERC-20s via the Arbitrum Bridge

  5. Decentralizes sequencing through Espresso shared sequencer

  6. Initially settles on Ethereum, then migrates to Litecoin mainchain

Is LitVM a zkRollup or Optimistic Rollup?

LitVM is a hybrid rollup that combines both:

  • Optimistic execution for fast transaction processing

  • ZK validity proofs for cryptographic security guarantees

This gives the speed of optimistic rollups with the security of zkRollups.

What makes the LTC bridge trustless?

Unlike traditional bridges that rely on multisig custodians, LitVM uses BitcoinOS's Grail bridge which:

  • Uses ZK-SNARK proofs to verify locked LTC

  • Requires only 1 honest validator (vs. majority consensus)

  • Never places funds in third-party custody

  • Provides mathematical guarantees, not trust assumptions

How do I bridge assets from Ethereum?

LitVM supports the standard Arbitrum Bridge for EVM-native assets like ETH, USDC, and other ERC-20 tokens. This provides a familiar bridging experience for Ethereum users and access to deep EVM liquidity.

Does LitVM require changes to Litecoin?

No. LitVM works with Litecoin's existing protocol. No soft forks, hard forks, or upgrades to Litecoin are required.

What's the difference between zkLTC and wrapped LTC?
zkLTC
Wrapped LTC (Traditional)

Trustless ZK-verified

Custodian-dependent

Non-custodial

Third-party custody

1/n security (1 honest node)

m-of-n trust (honest majority)

On-chain verification

Off-chain attestation

Tokens

What is zkLTC?

zkLTC is a 1:1 representation of LTC on LitVM. When you bridge LTC to LitVM via the BitcoinOS Grail bridge, you receive zkLTC which is used for:

  • Gas fees (transaction costs)

  • DeFi protocols (trading, lending, etc.)

  • The primary base asset on LitVM

Every zkLTC is backed by LTC locked on the Litecoin mainchain.

What is $LITVM?

$LITVM is the governance and utility token of the LitVM ecosystem. It provides:

  • Voting rights in the Litecoin DAO

  • Share of protocol revenue (sequencer fees)

  • Ecosystem access and benefits

How can I get $LITVM?

$LITVM will be available after the Token Generation Event (TGE). Ways to participate:

  • Follow @LitecoinVM for early access programs

  • Participate in testnet activities

  • Join community campaigns (like LitVM’s ongoing Xeet campaign)

Using LitVM

How do I add LitVM to my wallet?

See our Add to Your Wallet guide. You can:

  1. Use the one-click add on the LitVM Network Hub (Coming Soon)

  2. Add manually using RPC details

  3. Use ChainList.org

How do I get testnet zkLTC?

  1. Add LitVM Testnet to your wallet

  2. Visit the Testnet Faucet

  3. Connect your wallet and request zkLTC

  4. Tokens arrive in ~30 seconds

Which wallets work with LitVM?

Any EVM-compatible wallet works:

  • MetaMask

  • Rabby

  • Coinbase Wallet

  • Trust Wallet

  • Rainbow

  • WalletConnect-compatible wallets

Can I deploy smart contracts?

Yes. LitVM is fully EVM-compatible. You can deploy using:

  • Foundry

  • Hardhat

  • Remix

Use Solidity, Vyper, or any EVM-compatible language.

What are gas fees like?

LitVM targets sub-cent transaction fees, with typical costs:

  • Simple transfer: ~$0.001

  • DEX swap: ~$0.01-0.02

  • Contract deployment: ~$0.05-0.50

Fees are paid in zkLTC.

Security

Is LitVM safe?

LitVM inherits security from multiple layers:

  1. Litecoin: 14+ years of uninterrupted PoW security

  2. Ethereum: World's most decentralized smart contract platform (Phase 1 settlement)

  3. ZK Proofs: Mathematical guarantees of execution correctness

  4. Espresso: Decentralized sequencing prevents censorship

  5. BitcoinOS Grail: Non-custodial bridging with 1/n security

  6. Arbitrum Bridge: Battle-tested rollup bridge for EVM assets

Has LitVM been audited?

Audits are in progress. Results will be published publicly. Component technologies (Arbitrum Nitro, BitcoinOS, SP1) have undergone separate audits.

What happens if the sequencer goes down?

Espresso's shared sequencer provides redundancy. If primary sequencers fail:

  • Other sequencers in the network continue operation

  • Users can force-include transactions via L1

  • Funds are never at risk—you can always withdraw via the bridge

Are my funds safe if LitVM has issues?

Yes. Because zkLTC is backed 1:1 by LTC on Litecoin mainchain:

  • You can always bridge back to native LTC

  • Proofs are verified on-chain

  • No single entity can steal funds

Developers

Is LitVM EVM-compatible?

Yes, fully EVM-equivalent. Deploy the same contracts you'd deploy on Ethereum, Arbitrum, or any EVM chain. Standard tooling works:

  • Solidity/Vyper

  • Hardhat/Foundry/Remix

  • Ethers.js/Web3.js

  • All standard ERC standards

Where can I find the RPC endpoints?

Testnet:

Mainnet: Coming after TGE

Are there developer grants?
How do I get developer support?

  1. Telegram: Fastest response for quick questions

  2. GitHub: File issues for bugs

  3. Documentation: Check these docs first!

  4. Twitter: Tag @LitecoinVM for visibility

Ecosystem

What can I do on LitVM?

  • Yield: Earn yield on LTC with on-chain DeFi and institutional-grade vaults

  • DeFi: Trade, lend, borrow, provide liquidity

  • RWAs: Tokenized real-world assets

  • AI: AI agents and AI-integrated applications

  • Payments: Fast, cheap and programmable Litecoin transactions

  • NFTs: Mint, trade, and use Litecoin-native NFTs

  • Gaming: On-chain games and rewards

Will stablecoins be available?

Yes. USDC, USDT and other stablecoins can also be bridged from Ethereum via the Arbitrum Bridge. We also expect Litecoin-based stablecoins to make an appearance on LitVM.

Can I bridge assets other than LTC?

Yes! LitVM has a dual bridge architecture:

From Litecoin (BitcoinOS Grail Bridge):

  • LTC → zkLTC

From Ethereum (Arbitrum Bridge):

  • ETH

  • USDC, USDT, and other stablecoins

  • ERC-20 tokens

Future support planned for Litecoin-native assets:

  • Litecoin Ordinals

  • Litecoin Runes

  • LTC-20 tokens

  • BitcoinOS Charms

Token & Economics

What is the total supply of $LITVM?

The full tokenomics details can be found here. Key points:

  • 51% community allocation via the Litecoin DAO

  • Revenue sharing from sequencer fees

  • Governance rights

How does revenue sharing work?

$LITVM holders and/or stakers receive a share of sequencer fees—the fees generated from transaction ordering and batching on the network. This creates sustainable value tied to actual network usage.

Why does LitVM have two tokens?

zkLTC serves as the gas token (1:1 backed by LTC), while $LITVM is the governance and utility token. This separation preserves Litecoin's sound money properties for transactions while enabling community coordination and revenue sharing through a dedicated governance token.

Troubleshooting

My transaction is stuck

  1. Check you have enough zkLTC for gas

  2. Try increasing gas limit

  3. Reset your wallet's nonce

  4. Wait for network congestion to clear

I can't connect to the network

  1. Verify RPC URL is correct

  2. Check Chain ID matches

  3. Try an alternative RPC endpoint

  4. Clear wallet cache and reconnect

Bridge transaction not completing

For LTC bridging (BitcoinOS Grail):

  1. Ensure you have enough LTC for fees on mainchain

  2. Wait for sufficient confirmations (may take several blocks)

  3. Check bridge UI for status

For ETH/ERC-20 bridging (Arbitrum Bridge):

  1. Ensure transaction confirmed on Ethereum

  2. Wait for the standard confirmation period

  3. Check Arbitrum Bridge UI for status
