LitVM is a smart contract execution layer for Litecoin that enables programmable logic — tokens, DeFi applications, NFTs, and other contract-based functionality — on the Litecoin network. Smart contracts on Bitcoin-family chains (Litecoin included) have historically been limited compared to Ethereum; LitVM extends Litecoin's capabilities in this direction while preserving Litecoin's core properties (scrypt mining, 2.5-minute blocks, MWEB privacy). LitVM is compatible with standard Ethereum tooling in important ways, lowering the barrier for developers familiar with EVM-based development.

Why a smart contract layer on Litecoin

Bitcoin and Litecoin were designed as peer-to-peer digital cash — simple, secure, predictable. Their scripting is deliberately limited: you can define spending conditions, but you can't run arbitrary programs. Ethereum took the opposite approach — full programmability at the base layer, accepting tradeoffs in complexity and fee volatility. Over time, Bitcoin-family chains have added programmability through various approaches: sidechains, rollups, extension blocks, and virtual-machine layers. LitVM is Litecoin's version of this pattern. It keeps the Litecoin base layer exactly as it is — fast, cheap, scrypt-mined — and adds smart contracts as a layer on top. Applications that need programmable logic (DeFi, token issuance, NFTs) use LitVM. Users who just want to send and hold LTC interact with the base layer unchanged.

How LitVM works

At a high level, LitVM runs smart contract code and commits periodic state roots back to the Litecoin base chain, anchoring contract state to Litecoin's proof-of-work security. Developers write contracts in Solidity (the Ethereum contract language) or other supported languages, deploy to LitVM, and users interact via standard EVM-style transactions — except gas is paid in LTC rather than ETH, and finality inherits from Litecoin block times. From a user's perspective in Lite Wallet: you see LitVM token balances alongside your LTC balance, you sign LitVM transactions with the same 12-word paper key that controls your standard LTC, and you pay fees in LTC. Under the hood, LitVM handles the execution layer.
