LTCVM alpha terms of use

LTCVM and its LTC bridge are alpha software: new, experimental, and not yet externally audited. Please read this page before you use them. By using this site, the LTCVM chain or the bridge, you agree to these terms.

Last updated 1 October 2026

What this is

• LTCVM is a separate blockchain, a Layer 1 on Metal Blockchain, that uses Litecoin's address formats and transactions. It is not the Litecoin network.
• The bridge moves LTC between Litecoin and LTCVM. LTC you deposit is locked on Litecoin in a multisig address, and the same amount, less a small fee, is issued to you on LTCVM. When you withdraw, LTC on LTCVM goes back to the bridge, which pays LTC on Litecoin to the address you choose.
• The web wallet and the Mac app keep your key on your own device. We never see it.

Alpha means real risk

• You could lose what you send. The software may have bugs that lose, freeze or delay funds. Only use amounts you can afford to lose.
• Limits apply. During the alpha, each deposit and the total on LTCVM are capped: at the time of writing, 1 LTC per deposit and 10 LTC in total. The current limits are always shown on the site. A deposit that doesn't fit isn't credited: see held deposits.
• The operator holds the bridge's keys during the alpha. During the alpha, one operator, Paul Grey, holds all of the bridge's signing keys, so you are trusting that operator to run the bridge honestly and keep those keys safe. If they were lost or stolen, the locked LTC could be lost. Caps and daily limits are enforced by the signer software; they don't limit what someone holding the keys could take. Moving the keys to independent operators is planned (roadmap); it isn't done yet.
• No audit, no insurance. The bridge hasn't had an external security audit. Funds aren't insured or protected by any government scheme, and the operator isn't a bank.
• Pauses. The bridge may be paused at any time, for maintenance or security, without notice. Deposits made during a pause are credited after it resumes; withdrawals wait until then.
• Timing. Payments on LTCVM are usually final in under a second. Moving LTC onto or off LTCVM waits for confirmations on Litecoin, and can take longer when that network is busy or the bridge is paused.

Your key, your responsibility

• Your key is stored only in your browser or the app. Back it up. If you lose it, or your browser's data is cleared, nobody can recover your LTC.
• Check addresses before you send. A payment sent to the wrong address or the wrong network may be unrecoverable. Litecoin and LTCVM addresses look the same: make sure you're on the network you mean.

Fees

Network fees on both chains, and the bridge's fee, are taken from the amount moved. They're shown before you confirm.

Held deposits and refunds

• A deposit that is too small, too large, sent without a destination, or that can't be credited for another reason is held. It can be refunded to the sender on Litecoin, less network fees. A deposit too small to be worth the network fee may not be refunded.
• Refunds are made by the operator on request, after checks. See contact.

Changes, and ending the alpha

The limits, fees and these terms may change, and the alpha may end. If the service ends, the operator intends to give notice on this site and let you withdraw your LTC first.

What you agree not to do

• Use the service where it is unlawful for you, or if you are subject to sanctions.
• Use it for anything illegal, or try to attack, overload or exploit it. If you find a vulnerability, please report them privately to Paul Grey via metallicus.com instead; we're grateful for it.

No advice, no warranty, limited liability

Nothing on this site is financial, investment, legal or tax advice. You're responsible for your own decisions, and for any taxes on your transactions.

The software and the service are provided as is, without warranties of any kind. To the fullest extent the law allows, the operator isn't liable for any loss of funds, data or profits, or for indirect losses, arising from your use of the service. Where the law doesn't allow this, liability is limited to the amount you deposited.

Open source and contact

The software is open source, at github.com/MetalBlockchain/ltc-vm (the repository is being made public). Developed by Paul Grey @ metallicus.com.
