MWEB privacy — every platform.
FEATURE
MWEB privacy — every platform.
Litecoin transactions default to a public ledger — every amount, every address. MWEB changes that. Lite Wallet ships confidential MWEB transactions on Windows, macOS, Linux, iOS, and Android.
MWEB — MimbleWimble Extension Block — is a Litecoin protocol upgrade activated in May 2022 that adds confidential transactions to the LTC chain. Transaction amounts are hidden and addresses are unlinked through blinding factors and one-way pegging. Lite Wallet implements MWEB on Windows, macOS, Linux, iOS, and Android, with one-tap peg-in and peg-out between the standard Litecoin ledger and the MWEB extension block.
What is MWEB?
A privacy extension, not a separate coin
MWEB is an extension block that runs alongside the standard Litecoin ledger. Same LTC, same 84 million cap. Funds move in via peg-in, transact privately inside the MWEB block, and move back out via peg-out. There is no separate token and no bridge — MWEB is native Litecoin.
Activated May 2022
MWEB activated on the Litecoin mainnet at block 2,257,920. Activation followed LIP-0002 and LIP-0003 proposals and required a soft fork with miner signaling over a lock-in period. Any Litecoin node running a recent-enough version of Litecoin Core understands MWEB.
Built on MimbleWimble
MimbleWimble is the protocol Grin and Beam pioneered — a clean-slate privacy design that blinds amounts and aggregates transactions so the chain carries no per-transaction trace. MWEB brings those properties to Litecoin as an opt-in extension.
How MWEB works
Confidential amounts
MWEB uses Pedersen commitments — cryptographic blobs that hide the amount of a transaction while still proving inputs equal outputs. Observers see that a valid transaction occurred; they don't see how much.
Unlinked addresses
MWEB addresses are one-time, derived from a view key and a spend key. No reused address means no clustered spending history. Even a wallet that receives 100 payments shows 100 distinct MWEB addresses on-chain.
Peg-in and peg-out
To use MWEB, a user sends LTC from the standard Litecoin ledger into the MWEB extension (peg-in). Funds inside MWEB can be transacted confidentially. Sending LTC back out to a standard Litecoin address is a peg-out. Both operations are on-chain transactions in a single wallet flow.
Aggregated transactions
MWEB transactions inside a block are aggregated — the block contains one combined transaction instead of many separate ones. This further obscures the relationship between individual inputs and outputs and reduces on-chain footprint.
MWEB in Lite Wallet
One-tap private transactions on every platform.
Confidential amounts
Lite Wallet's MWEB send flow hides amounts from the Litecoin chain. You see your balance; the chain sees a valid transaction without the number.
One-time addresses
Every MWEB address is derived fresh. Lite Wallet generates receive addresses automatically and never reuses them — so payments to you aren't clustered on-chain.
Peg-in and peg-out
Move LTC into MWEB for privacy, move it back to the standard ledger for exchange deposits. Lite Wallet handles both in a single signed transaction.
Every platform
MWEB ships on Windows, macOS, Linux, iOS, and Android versions of LiteWallet. Same MWEB address format, same 12-word paper key, every device.
SPV-friendly
Lite Wallet uses SPV mode on desktop and mobile — no full-node sync required. MWEB balance and history update against the MWEB extension block directly.
Opt-in, per transaction
MWEB is not forced on every transaction. Standard Litecoin remains the default. Choose MWEB when privacy matters — for a salary, a payment, or ongoing receive address rotation.
When to use MWEB
Receiving income you'd rather not publish
A salary, a freelance payment, a recurring transfer — anything you'd rather not tie to a public, permanent on-chain record. Share an MWEB receive address with the sender; your balance grows confidentially.
Sending to someone without exposing your wallet
Standard Litecoin transactions reveal your change address and let observers cluster future transactions from it. MWEB sends don't. If you care about your counterparty not being able to profile your balance, MWEB solves it.
Holding with privacy while retaining liquidity
Peg into MWEB, hold confidentially, peg out to a standard address when you're ready to move to an exchange or a specific payment target. You keep the usual Litecoin liquidity profile without a permanent public history.
What MWEB doesn't do
MWEB hides amounts and unlinks addresses inside the MWEB extension — it doesn't hide the act of peg-in or peg-out from the standard Litecoin ledger. Observers can see a wallet pegged 1 LTC into MWEB at time T; they can't see what happened to it inside. For maximum privacy, delay between peg-in and peg-out, and peg out to a different address than you pegged in from.
