From digital silver to zk proofs.
70 questions across the whole course. Each module ends in a quiz and a badge, and the order matters.
Litecoin Foundations

Building on LitVM
Ship a contract with Foundry or Hardhat, then handle the EVM differences that break naive Ethereum code.

Every badge is drawn by the contract itself.
The artwork is generated as SVG inside the ERC-1155 contract on LiteForge, so there is no IPFS pin to expire and no gateway to go offline. Badges are soulbound: they record that you did the work, and they cannot be traded away.
Collect all seven and the contract lets you mint the certificate. That check runs on chain against your own balances, so nobody can hand it to you.
- Standard
- ERC-1155, soulbound
- Metadata
- On-chain SVG
- Network
- LiteForge testnet

How a badge gets earned.
Read
Each module is a single page written from the litepaper, the docs, and the live network. No prior Litecoin experience assumed.
Pass
Ten questions drawn in random order. Miss more than two and you retake it. Every answer explains itself afterwards.
Mint
A passing score signs a voucher for your address. You submit it yourself and pay testnet gas in zkLTC from the faucet.
You will need these before module six.

Questions people actually ask.
Short answers here, full reasoning inside the modules.
- What is LitVM?
- LitVM is Litecoin's first trustless EVM rollup. It brings smart contracts to Litecoin using Arbitrum Nitro for execution and Succinct SP1 zero-knowledge proofs for validity, while LTC is bridged non-custodially through BitcoinOS's Grail bridge. It is officially endorsed by the Litecoin Foundation.
- Is LitVM a zkRollup or an optimistic rollup?
- Both. LitVM is a hybrid: transactions execute optimistically through Arbitrum Nitro for immediate confirmations, and Succinct's SP1 zkVM generates validity proofs over that execution so finality arrives in minutes instead of the seven-day challenge window a pure optimistic rollup needs.
- What is zkLTC and how does it differ from wrapped LTC?
- zkLTC is the gas token on LitVM, backed one to one by LTC locked on the Litecoin mainchain. Unlike wrapped tokens it has no custodian: deposits lock LTC in a Taproot output, a ZK-SNARK proof verifies the lock, and redemption is guaranteed by the protocol rather than by a third party staying solvent.
- How do I connect to the LiteForge testnet?
- Add the network with chain ID 4441, RPC endpoint https://liteforge.rpc.caldera.xyz/http, and currency symbol zkLTC. The one-click option is the Add to Wallet button at testnet.litvm.com. Fund the wallet from the Caldera Hub faucet, which rate limits VPN and proxy traffic.
- Is LitVM Academy official?
- No. LitVM Academy is an independent, community-built course. It is not affiliated with LitVM, Lunar Digital Assets, or the Litecoin Foundation. Every lesson links to the primary sources it was written from so you can check any claim against the official documentation.
- Do the badges cost anything?
- No. Badges are minted on the LiteForge testnet, where gas is paid in free faucet zkLTC. They have no monetary value, cannot be traded because they are soulbound, and exist only as a record that a specific wallet passed a specific quiz.
- What happens if I fail a quiz?
- Nothing is lost. Each quiz needs 8 correct answers out of 10, grading happens on the server, and you can retake it as often as you like. Questions and answer options are reshuffled on every attempt, and the review screen explains every question afterwards.
- Which wallets work with LitVM?
- Any EVM-compatible wallet, including MetaMask, Rabby, Coinbase Wallet, Trust Wallet, Rainbow, OKX Wallet, and anything that supports WalletConnect. Because testnet applications may be unaudited, LitVM recommends using a fresh wallet that holds nothing of value.
Module one takes nine minutes.
Start with how Litecoin actually works, then follow the stack up to the rollup. No wallet needed until module six.
