TLDR
- Invalid MWEB transactions caused a brief Litecoin chain split.
- The valid Litecoin chain overtook the invalid chain after 13 blocks.
- Earlier MWEB bug activity created an inflated peg-out of 85,000 LTC.
- Cross-chain platforms faced losses after processing invalid-chain activity.
- LTC is trading near $55 within a broader $50–$60 range.
Litecoin faced renewed attention after abnormal activity tied to invalid MimbleWimble Extension Block transactions caused a brief chain split, followed by a network reorganization that removed the invalid chain.
According to reports, the incident began when part of the network accepted blocks that did not follow proper consensus rules. Mining pool f2pool continued mining on the valid chain, helping it overtake the invalid chain after a 13-block gap.
The issue was linked to Litecoin’s MWEB privacy layer, where a validation flaw earlier allowed an attacker to create an inflated peg-out of more than 85,000 LTC. Developers later coordinated fixes, while miners helped prevent further movement of affected outputs.
Litecoin Chain Split Exposes MWEB Risk
A chain split occurs when different parts of a blockchain network follow separate versions of the ledger. In this case, one Litecoin chain followed the valid rules, while another included invalid MWEB transactions.
The valid chain eventually gained more cumulative work and became the accepted ledger. The invalid blocks were discarded through a standard reorganization process.
On 2026-04-25, the @Litecoin network faced abnormal activity involving invalid MWEB transactions and a temporary chain split.
f2pool detected the issue in real time and responded immediately, continuing to mine on the valid chain under the correct consensus rules.

Litecoin creator Charlie Lee acknowledged the role of f2pool in responding quickly. Without miners continuing to support the valid chain, the disruption could have lasted longer and created more uncertainty for users and services.
The event showed that Litecoin’s core network was able to recover, but it also exposed how bugs in privacy or extension layers can affect wider network confidence.
Cross-Chain Platforms Face Losses
While Litecoin restored normal operations, external platforms faced losses after processing activity linked to the invalid chain. Cross-chain systems such as swap and bridge infrastructure can be exposed when they act on transactions before a network fully settles.
Reports identified NEAR Intents and THORChain among platforms affected by transactions that later disappeared after the invalid chain was removed.
The incident shows the risk of cross-chain systems relying on fast confirmation assumptions. When a base-layer chain reorganizes, connected platforms may be left with assets already exchanged against transactions that no longer exist.
Litecoin developers have since released fixes for the original MWEB validation flaw and the later node-handling issue. The MWEB balance was restored, and the network resumed normal operation.
LTC Price Holds in Tight Range
Litecoin’s price has remained near the $55 area, moving within a broader $50 to $60 range. The token is trading in a compression phase as market participants watch for a breakout or another rejection.
Technical charts show an ascending triangle pattern, with rising support from April lows and repeated resistance near $56.50 to $57. A break above that zone could shift attention toward the $59 to $60 area.

If LTC fails to clear resistance, the price may continue moving sideways inside the current range. A loss of rising support could bring the $50 to $52 area back into focus.
Momentum remains mixed. Buyers have defended higher lows, but each move into resistance has struggled to produce a decisive breakout.
