Litecoin MWEB (MimbleWimble Extension Blocks) is an optional privacy layer activated on Litecoin in 2022: coins moved into MWEB hide their amounts and addresses on-chain, but moving in and out of MWEB ("peg-in" and "peg-out") stays visible, and only wallets that support it can use it. It makes Litecoin much more private than Bitcoin, but unlike Monero, privacy is opt-in. You can move between the two with no-KYC swaps like LTC → XMR.
- 2022 MWEB activated
- Opt-in privacy
- Hidden amounts & addresses inside MWEB
- ~2.5 min Litecoin block time
How MWEB works
MWEB runs alongside normal Litecoin blocks as an "extension block". Inside it, transactions use MimbleWimble cryptography: amounts are hidden with confidential transactions, there are no reusable public addresses on-chain, and inputs and outputs from many transactions can be merged so they're hard to link. Your wallet shows a separate MWEB address (starting ltcmweb1). To use it, you peg in regular LTC to MWEB, transact privately, and peg out back to a normal address when needed — those two steps are visible on the main chain.
MWEB vs Monero vs Bitcoin at a glance
| Litecoin MWEB | Monero | Bitcoin | |
|---|---|---|---|
| Privacy by default | No — opt-in | Yes, always | No |
| Hides amounts | Yes, inside MWEB | Yes | No |
| Hides addresses | Yes, inside MWEB | Yes (stealth addresses) | No |
| Hides sender | Partially (transaction merging) | Yes (ring signatures) | No |
| Visible entry/exit | Yes (peg-in / peg-out) | No entry or exit — all private | — |
| Exchange support | Few exchanges accept MWEB addresses | Delisted from some big exchanges | Everywhere |
For a deeper comparison of always-on privacy vs optional privacy, read Monero vs Zcash — the same trade-off applies to MWEB.
Which wallets support Litecoin MWEB?
- Litecoin Core — the reference desktop wallet.
- Cake Wallet — mobile and desktop, with MWEB addresses built in (see our Cake Wallet guide).
- Support in other wallets is growing; check that your wallet shows an
ltcmweb1…address before relying on it.
Most exchanges, including instant swap services, send and receive regular Litecoin. Use a normal LTC address for swaps, then peg in to MWEB from your own wallet.
How to use MWEB privately (step by step)
- Install an MWEB wallet such as Cake Wallet or Litecoin Core.
- Get LTC without KYC — swap from another coin on BTC → LTC to a regular LTC address.
- Peg in by sending the LTC to your own MWEB address.
- Transact inside MWEB with others who use MWEB addresses.
- For full privacy, swap to Monero with LTC → XMR — see our LTC to XMR guide.
Why some exchanges reacted to MWEB
When MWEB launched, several regulated exchanges in South Korea delisted Litecoin, citing anti-money-laundering rules on anonymous transactions — the same reason big exchanges drop Monero (see why Monero is delisted). Most global exchanges kept LTC but only handle non-MWEB transfers. No-KYC instant exchanges continue to swap LTC normally — compare them on best Litecoin exchanges.
Frequently asked questions
What is Litecoin MWEB?
MimbleWimble Extension Blocks: an optional privacy layer on Litecoin, live since 2022, that hides amounts and addresses for coins moved into it.
Is Litecoin MWEB as private as Monero?
No. MWEB is opt-in and the peg-in and peg-out steps are visible, while every Monero transaction is private. MWEB is still far more private than Bitcoin.
Can I send MWEB Litecoin to an exchange?
Most exchanges don't accept MWEB addresses. Peg out to a regular LTC address first, then send to the exchange.
Does MWEB cost more in fees?
MWEB transaction fees are small, similar to regular Litecoin. Pegging in and out are separate transactions with their own small fees.
How do I swap Litecoin to Monero without KYC?
Choose LTC → XMR, paste your Monero address, send regular LTC and receive XMR in 10–30 minutes with no account.
Swap now: LTC → XMR, BTC → LTC or LTC → BTC. No account, no ID, no logs.
