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:
Executes smart contracts using Arbitrum Nitro (EVM-compatible)
Uses Succinct zkVM to generate validity proofs
Bridges LTC trustlessly via BitcoinOS Grail bridge
Bridges ETH and ERC-20s via the Arbitrum Bridge
Decentralizes sequencing through Espresso shared sequencer
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.
Are there any EVM differences I should know about?
Yes, a few minor ones. Most notably, block.number returns the approximate Ethereum L1 block number, not the LitVM block number. See our EVM Differences guide for details.
What's the difference between zkLTC and wrapped LTC?
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:
Use the one-click add on the LitVM Network Hub (Coming Soon)
Add manually using RPC details
Use ChainList.org
How do I get testnet zkLTC?
Add LitVM Testnet to your wallet
Visit the Testnet Faucet
Connect your wallet and request zkLTC
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:
Litecoin: 14+ years of uninterrupted PoW security
Ethereum: World's most decentralized smart contract platform (Phase 1 settlement)
ZK Proofs: Mathematical guarantees of execution correctness
Espresso: Decentralized sequencing prevents censorship
BitcoinOS Grail: Non-custodial bridging with 1/n security
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
Are there developer grants?
51% of the total $LITVM token supply is reserved for community and ecosystem via the Litecoin DAO. This will include grants and bootstrapping capital for ecosystem applications.

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

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
Check you have enough zkLTC for gas
Try increasing gas limit
Reset your wallet's nonce
Wait for network congestion to clear
I can't connect to the network
Verify RPC URL is correct
Check Chain ID matches
Try an alternative RPC endpoint
Clear wallet cache and reconnect
Bridge transaction not completing
For LTC bridging (BitcoinOS Grail):
Ensure you have enough LTC for fees on mainchain
Wait for sufficient confirmations (may take several blocks)
Check bridge UI for status
For ETH/ERC-20 bridging (Arbitrum Bridge):
Ensure transaction confirmed on Ethereum
Wait for the standard confirmation period
Check Arbitrum Bridge UI for status
