Why the Monero fork on October 5 leaves your XMR untouched: FCMP++ hits the stressnet

On Monday, October 5, 2026, a network forks at Monero. What it affects is not the main network where your XMR sits: a separate test network forks, one the developers call a stressnet. Anyone holding Monero therefore has nothing to do on that day: no wallet action, no withdrawal from an exchange, no swapping. The changeover this test is working towards is nonetheless the most far-reaching alteration to Monero's privacy in years, and it still has no date for the main network.

That separation is the whole core of the story. There is a hard, documented date, and it concerns a test environment. And there is a rebuild with an open date that decides how anonymous Monero will be in a few years and how exchanges in the EU will deal with it. This article sorts the two apart and tells you which of them concerns your coins.

What forks on October 5: the beta stressnet, not the Monero mainnet

The developer team behind the changeover released version v0.19.0.0-beta.3.0 on Friday, September 25, 2026, the so-called FCMP++ and Carrot beta stressnet v3.0. According to the developers, this package forks away from its previous test network on October 5, 2026 at block height 3102800.

A stressnet is a deliberately loaded test network. It exists to bombard a protocol with more transactions, more data and more participants than everyday use would produce, and to see where it breaks. The coins in it have no value, the blockchain in it is not Monero's, and a fork there changes nothing about the main network.

The distinction matters because news headlines about this date often say only "Monero hard fork on October 5". To a holder that sounds like a network changeover with pressure to act, of the kind Monero used to have roughly every six months. This time it is a test run in which volunteer node operators take part.

Monero price at around 550 dollars: weekly high 563.50, weekly low 525

The Monero price stands at around $550 at midday on Sunday. Over the week barely anything has moved: the gain across seven days is about 0.4 percent, according to data from CoinPaprika. Within that week there was room enough. XMR marked the weekly high on October 3 at $563.50 and the weekly low on September 28 at $525, measured on Kraken's daily candles. A good 7 percent lies between those two points.

By market capitalisation Monero is thereby the fourteenth-largest cryptocurrency. From its own record, which XMR reached in January 2026, the price is around 31 percent away. That is remarkably little for a coin the large regulated trading venues in Europe have not listed for years.

The fork date itself has not shown up in the price, and that is consistent: a test network yields no returns and changes no supply. Anyone who looked for a reaction to the announcement this week finds none.

FCMP++ explained: from 16 decoys to the whole blockchain

FCMP++ stands for Full-Chain Membership Proofs. It is a cryptographic procedure with which a sender proves that the amount being spent comes from a particular set of earlier incoming payments, without revealing which one exactly.

Today Monero works with ring signatures. When you send XMR, your wallet mixes the incoming payment actually used with fifteen others from the blockchain. An observer sees sixteen possible origins and cannot say which of them is the real one. That size of sixteen has been the standard for years and is at the same time the known weak point: anyone collecting enough additional knowledge can rule out candidates and narrow the circle.

FCMP++ replaces that small ring with a proof against the entire chain history. Instead of one of sixteen, an output is in future meant to be one among more than 150 million, that is, among practically all the payment outputs Monero has ever created. The additional knowledge with which investigators shrink rings today thereby loses its point of attack, because there is nothing left to shrink.

Carrot: what the addressing protocol changes for existing Monero addresses

Carrot is the second building block of the package and concerns how Monero addresses are constructed. It is a new addressing protocol which, according to the developers, brings additional properties in security, privacy and usability while remaining backward compatible with existing addresses.

Backward compatible here means: an address you have deposited somewhere today, say with a service that pays out XMR to you, is meant to keep working after the changeover. For holders that is the reassuring news at this point, because exchanging receiving addresses across several services is one of the most error-prone operations there is.

Stressnet v3.0 in detail: hot-cold wallets, Transaction Relay v2 and RandomX v2

Version v3.0 brings, according to the release notes, three notable additions into the test. First, support for hot-cold wallet set-ups, in which a wallet without access to the spend keys prepares transactions and a separate device never connected to the network signs them. That is the procedure hardware wallets also work with, and its availability helps decide whether devices will follow the changeover later.

Second, larger improvements to the Transaction Relay v2 protocol, that is, to the way transactions are passed on between nodes. Third, support for RandomX v2, the reworked mining algorithm. Added to that are fixes from the previous stressnet version and the current state of Monero's main branch.

That hot-cold support is entering the test precisely now is the practically most relevant detail of the whole package. It is the point at which it is decided whether you will still be able to keep your coins on a separate device after a later mainnet changeover, or whether you will have to wait for new firmware.

Why the official roadmap names no mainnet date

On the project roadmap at getmonero.org FCMP++ appears under "Full-Chain Membership Proofs" in the section of upcoming work, together with the Seraphis codebase and Jamtis. There is no date there, no version number either, and Carrot is not listed at all.

That is not an omission but the way the project works. Monero has no company, no board and no venture capitalist's treasury in the background that could enforce a delivery date. Changeovers arise in open developer meetings and are released when audits and tests are finished. The stressnet fork on October 5 is a step in that procedure, not the announcement of a launch.

For you that means: a mainnet activation of FCMP++ may come in months, it may also slip beyond a year. Anyone wanting to draw consequences from the technology now is drawing them from an intention, not from a timetable. Figures attached to a date nobody has named are, at this point, invention.

The delisting wave: how MiCA and the anti-money-laundering regulation pushed Monero out of EU order books

While work goes on at the protocol, the trading venue for Monero in Europe has shrunk over the years. Binance took XMR off its European offering in February 2024, Bitpanda in the same year, Bitvavo in 2025. Kraken ended support for Monero in the European Economic Area and, after the deadline passed, converted remaining balances that had not been withdrawn into Bitcoin.

The counts across all trading venues diverge depending on the cut-off date. Industry counts name around 73 exchanges that have delisted or restricted Monero, against roughly 51 in 2023; which month exactly is meant varies between sources. The direction is unambiguous, the exact figure you should not read as a fixed value.

The reason lies in three sets of rules that work together. The provisions for crypto service providers under MiCA require an authorised exchange to be able to trace the origin and destination of funds. The EU anti-money-laundering regulation AMLR tightens that further for anonymity-enhancing assets. And the FATF travel rule requires sender and recipient data to be supplied with transfers. A coin whose protocol necessarily conceals origin and amount cannot be reconciled with those duties.

Worth noting is the separation between trading and ownership. Owning and using Monero is legal in Germany; there is no ban. What is regulated are the service providers, not the holders. That is exactly why the wave hits the buying route and not the holding in your own wallet.

Buying Monero in Germany: which routes remain after the delistings

For a purchase out of Germany the situation is uncomfortable. The large MiCA-authorised providers through which trading usually happens here do not list XMR. Anyone looking for Monero ends up at trading venues outside EU authorisation, at decentralised exchanges, or at atomic swaps, where Bitcoin is bought first and then swapped.

As remaining centralised trading venues with XMR pairs, industry overviews name KuCoin, MEXC, Gate.io, the small TradeOgre and Kraken outside the EEA. Each of those routes brings its own drawbacks: no MiCA authorisation for the German market, no access to a German complaints body, and, in the event of insolvency or a hack, a legal position you can hardly assess beforehand. If you want to compare how regulated providers in Germany work, a look at our comparison of crypto exchanges helps, even though you will not find XMR there.

The sober sentence on this is: with Monero today the buying route is the part carrying the greatest risk, not the technology. The protocol works and is being extended. The question of which third party you get the coin through and how well you are protected there is the harder one.

Liquidity and spread: what a shrunken market means for your execution

When order books fall away, the same trading spreads across fewer venues. Daily turnover at Kraken was in the range of four to nine thousand XMR per day this week. That is tradeable, but it is not a depth in which a large order disappears without trace.

In practice that means two things. First, the difference between the buy and the sell price is felt faster with Monero than with Bitcoin or Ether, especially at weekends and in the quiet hours. Second, a single larger sale moves the price more. The 7 percent gap between the weekly low and the weekly high arose without any news at all; that is an indication of how thin the book is in stretches.

Anyone buying through a market order pays that difference immediately. A limit order you set yourself takes the surprise away, and with it the certainty that it will be filled.

Custody and wallet version: what to check now

From the stressnet fork no task follows for your mainnet balance. From the direction in which the rebuild is running, one does. Monero regularly requires up-to-date wallet software at network changeovers, and FCMP++ reaches deeper into the transaction structure than the changeovers of past years.

It therefore makes sense to know now what you are holding custody with. Are you running a wallet that still receives updates? Does your balance sit on a hardware device whose manufacturer still maintains Monero? Do you have a working backup of your recovery phrase, kept separately from the device? Those three points decide whether a future changeover is an update for you or a problem. Which devices support Monero and how they differ in handling and price is set out in our hardware wallet comparison.

The second point concerns coins sitting with a third party. Holding Monero on an exchange that one day delists XMR is the pattern that has produced the same deadlines again and again over past years: trading halt, then withdrawal deadline, then forced conversion into Bitcoin. Anyone moving early into their own custody decides the timing themselves.

Leverage and liquidation: 20 percent of distance at fivefold leverage

Part of the fork is a point that has nothing to do with Monero in particular. Around dated protocol events, volatility rises with many coins, even when the event has, as here, no economic substance at all. Anyone holding XMR with leverage will not be liquidated by the event itself, but may well be by the movement that expectations around it produce.

With a coin that has a thin book this effect is larger. A position at fivefold leverage sits, at a price of around $550, arithmetically some 20 percent away from its liquidation, and 20 percent is historically no great distance with Monero. This week's range alone already covered a third of it.

Tax and holding period: what applies to swapping XMR in Germany

For holders liable to tax in Germany, the one-year period applies to crypto assets as a private disposal: anyone holding longer than a year disposes tax-free under the law as it stands, and below that taxation applies above a threshold. Important for Monero in particular: a swap is a disposal. If you swap XMR into Bitcoin through an atomic swap, or an exchange itself converts your remaining balance into Bitcoin after a deadline, that triggers the same event as a sale.

With anonymity-enhancing assets that is the awkward spot, because the burden of proof lies with you, and a protocol that conceals amounts produces no convenient history for the tax office. Anyone holding XMR should document acquisition dates and acquisition costs themselves rather than rely on being able to reconstruct them later. Tools that keep such records can be found in our overview of crypto tax software. Worth noting is that tax law for crypto assets is currently being worked on; what applies today need not still apply next year.

Levels above and below: 563.50 dollars and the 525 zone

The two ends of this week serve as points of observation. Above sits the weekly high at $563.50, reached on October 3; beyond it begins the area in which the price last traded at the end of September. Below, the weekly low at $525 marks the point at which buyers stepped in on September 28, and beneath that the round level at $500.

These are observations, not targets and not a recommendation. Those two levels say nothing about where the price is heading; they only record where trading actually took place over the past days. In a market of this depth, each of those levels can be run through in a single day.

Monero and FCMP++: What to take away

1. October 5 is none of your business as a holder. A test network forks, and your mainnet balance stays untouched. For the main network there is no announced date, and FCMP++ has so far entered the project's roadmap only as a plan without a date.
2. Put your custody in order while no deadline is pressing. Maintained wallet software, a device whose manufacturer still supports Monero, and a separately stored backup are the work that should be done before a changeover. The hardware wallet comparison shows which devices come into question for it.
3. Treat the buying route as your greatest risk, not the technology. XMR is not to be had at the providers authorised in Germany, and every detour costs protection. Anyone wanting to check how regulated trading works will find the criteria in the exchange comparison.
