A GPG-signed list of the hashes is at https://www.getmonero.org/downloads/hashes.txt and should be treated as canonical, with the signature checked against the appropriate GPG key in the source code (in /utils/gpg_keys). To ensure that the files you download are those originally posted by the maintainers, you should both check that the hashes of your files match those on the signed list, and that the signature on the list is valid.

Two guides are available to guide you through the verification process: Verify binaries on Windows (beginner) and Verify binaries on Linux, Mac, or Windows command line (advanced).

Deprecating Monero's Custom Transaction Unlock Time

2026-05-10T00:00:00+00:00

Please be advised, the Custom Transaction Unlock Time feature is set to be deprecated at consensus with FCMP++. There is already a relay rule in place today that prevents nodes from accepting and relaying transactions with a Custom Unlock Time to the transaction pool (source). This is a formal announcement that the feature would be deprecated altogether with the FCMP++ fork, and new transactions with Custom Unlock Time set would not be able to enter the chain even if a miner mines them.

All transactions created after June 1, 2026, and with an Unlock Time set to unlock after the FCMP++ fork, would unlock immediately when the FCMP++ fork block hits the chain.

If we see a large influx of new Unlock Time transactions created between now and June 1, 2026, the feature may be deprecated earlier than June 1, 2026. Deprecating avoids complications with the FCMP++ wallet integration, enabling a smoother wallet experience for all users. Note that a FCMP++ fork date is not set at the time this is written.

This change will not affect transactions already created. If you, a user, created a transaction in the past with an Unlock Time set to a future date (even years from today), then you are not affected by this change. Your transaction will unlock based on the Unlock Time you set when you created the transaction. This change will only affect new transactions.

Why Deprecate?

The feature has caused a number of security, privacy, and fungibility issues over the years, and its known benefits do not outweigh its significant cons. Deprecating the feature has been discussed and supported for many years (see here, here, here, and here). Merchant software has neglected to check the Unlock Time on received Monero, and incorrectly assumed that the Monero received is spendable, leading to losses. Transactions with Custom Unlock Time stick out in the chain like a sore thumb, harming both privacy and fungibility. And the feature provides no known major benefit that is not achievable through some other means (for example, see Time-Lock Puzzles described in the PayMo paper).

It is a common misconception that Monero's Unlock Time is useful for known atomic swap or payment channel protocols. To date, no scheme has been specified that utilizes Monero's Unlock Time feature. Bitcoin's Hash Time Locked Contracts (HTLCs), for example, have unique capabilities that render them useful in atomic swap and payment channel protocols, that Monero's Unlock Time feature does not have.

FCMP++ capable wallets are slated to keep a rolling cache of locked Monero outputs, so that wallets will be able to construct FCMP++ transactions without revealing any identifying information about their own outputs to nodes. See more on the design here. The Unlock Time feature presents a Denial of Service vector because the cache could grow unbounded. Deprecating the feature now enables releasing FCMP++ capable wallets with no concern for this attack vector, enabling a smoother wallet experience for all users.

FCMP++ Optimization Competition Results

2025-08-27T00:00:00+00:00

We held a contest to optimize two libraries used in Monero's proposed upgrade to FCMP++: helioselene and ec-divisors. We have officially declared the winners of the contest!

EC Divisors (250 XMR prize)

Winner: @fabrizio-m

Fabrizio sped up the divisors library by over 95%. You can see the excellent submission here.

ec-divisors is a library implementing the calculation of divisors of elliptic curve points. These lead to efficient verification of scalar multiplications, as posited by Liam Eagen. FCMP++ uses EC Divisors to improve efficiency generally. This competition was focused on optimizing divisor construction, which affects transaction construction.

Managing slow divisors construction was a pain point for the FCMP++ integration. Fabrizio's 95%+ improvement effectively renders divisors construction negligible. Thanks to Fabrizio, we can now significantly simplify the final FCMP++ integration, and improve the user experience.

helioselene (100 XMR 1st place prize, 30 XMR 2nd place prize)

1st place: @lederstrumpf
2nd place: @rafael-xmr

Lederstrumpf's submission achieved a weighted speed-up of 22% on an AMD Ryzen 5600G, and improved the weighted WASM cycle count by 39%. The judges unanimously declared Lederstrumpf's submission the winner! Lederstrumpf's submission was the strongest foundation to build on. You can see the excellent submission here. As of this writing, @kayabaNerve has already improved on the submission here.

helioselene is a library implementing two curves, "Helios" and "Selene," which form a curve cycle towering Ed25519. Using a "tower cycle" over Ed25519 allows Monero to re-use the existing anonymity set while upgrading to FCMP++. This library is a critical component used in all aspects of FCMP++. Optimizing this library will therefore benefit all user-facing components of FCMP++ (daemon sync, wallet sync, and transaction construction).

Although not part of the official contest rules, we decided to award a 2nd place prize to Rafael, since we unanimously agreed Rafael's submission was 2nd best. Had we not received a submission from Lederstrumpf, we would have had an excellent submission to fall back on here. As such, we sought to reward Rafael's strong effort.

We received a number of quality submissions to this contest, and want to thank all contestants for participating! You can read more on our rationale for selecting the winner here.

What we learned

Form stricter bounds on exactly what code can be modified

Some code in a repo required for tests / benchmarks to run might not be in scope of the competition. Be as clear about which code is out of scope as possible. Explicitly tell contestants that modifiying certain code will be disqualifying.

Form stricter API requirements

Similar to the previous point, be crystal clear about the requirements the API of the code must take on and if it should even be allowed to be modified. Preferably provide downstream code that the API must compile and function correctly with.

Present concrete architectures and toolchains for which the code must run in constant-time

Code runs in constant-time or doesn't on specific architectures and toolchains. For example, LLVM to x86 generates variable-time code for u128 arithmetic in Rust, but constant-time code on x86_64. Give contestants examples of specific toolchains and architectures for which the code must compile to constant-time.

Allocate time for review and 2nd phase

No matter how well you think you define the competition rules, there may be scenarios which crop up where there was widespread confusion about the rules. There may be multiple submissions which have a lot of good work in them, but are in the gray area of validity. A review phase allows judges to clarify rules with contestants and refine submissions, and planning for this ahead of time helps to avoid misunderstandings.

Allocate time for deadline extensions

This one is pretty self-explanatory. Sometimes you need a deadline extension for unforseen circumstances, so allocate time for it.

Make a policy for non-1st place prizes

In a situation where anonymous submissions are allowed, 2nd place prizes can be gamed very easily. Also, game theory states that for a lot of competitions, the best incentive structure is winner-take-all. However, in the case where two submitters are certainly distinct competitors, and both submissions are close in quality, a 2nd place prize may be warranted. This is doubly true when parts of the code of the non-1st place are to be used in production code. Allocate funds for this scenario before the competition, but make sure to clarify that awarding such a prize is strictly up to the judgement of the judges.

Clarify rules for vendored dependencies

If you want to make rules about dependencies in the competition, make sure to specify rules about heavily modified and/or vendored dependencies before the start of the competition.

Spend more time marketing competition in specific circles where people do code competitions

There was a lot of good outreach for the FCMP++ competition, but some of the most fruitful outreach was to circles where there are already a lot of people doing coding/crypto competitions, who aren't necessarily involved in the Monero sphere.

Make sure that submitters always license their code under a permissive license

MIT, BSD, or even GPL, etc.

Setup an optional direct channel of communication for the contestants

Before the competiton starts, setup an offical, but optional, method of communication that lets judges push rule updates, feedback, announcements, etc to contestants. Otherwise, scrambling to find and message each contestant gets hectic very quickly.

Post-Mortem of find_and_save_rings() bug

2025-08-26T00:00:00+00:00

Quick Facts

Severity: HIGH if using untrusted remote daemon, MEDIUM otherwise
Affected versions: GUI/CLI wallet versions v0.12.0.0 to v0.18.4.1
Impact: Sends TXIDs of outgoing transactions to daemon after first time loading wallet from file, reducing sender anonymity
Fix: Update Monero CLI / GUI to v0.18.4.2
Workaround: TBD

Introduction

In 2018, a persistent "ring database" was added to wallet2 to solve a sender privacy problem with forks of Monero. If an enote was received before a fork occurs, and a wallet tries spending that enote after the fork occurs on both forks, the same key image will appear in the input to both of those transactions on the different forks. By necessity, one of the ring members must be the same between those two forks (the "true spend"). If no other ring members are shared between those two inputs, but both ring signatures verify correctly, then an external observer can pin which ring member is the "true spend". This destroys sender anonymity. To combat this, a ring database is populated in a user directory which maps spent key images to their ring signatures. Then, if a forked wallet tries to spend an enote already spent on another chain, it will lookup up ring signature data from the local ring database, and try to re-use as many decoys from that ring as possible. This reduces the sender anonymity risk for spending enotes across different forks.

There are basically three ways that the ring database can be populated: the ring indices from transactions can be added from 1) scanned outgoing transactions during a normal chain refresh 2) transactions submitted to the network from that wallet and 3) already-known outgoing transactions after explicitly fetching them from the daemon. The method tools::wallet2::find_and_save_rings() implemented the latter of the three schemes. Its purpose was to populate the ring database for already-existing wallets created before the v0.12.0.0 release after which rings were added during refresh, without having to rescan the whole blockchain. However, as it turns out, tools::wallet2::find_and_save_rings() was called more often than it should have given its niche purpose.

Reproducing

Here are steps to reproduce the privacy leak using the CLI wallet (assumes working daemon connection):

Create wallet (same-device keys, hardware wallet keys, multisig, etc), remember seed phrase if applicable
Receive an enote, spend said enote, wait 10 blocks
Delete (or move) wallet files, both keys and cache
Restore wallet and refresh before saving
Close wallet
(Optional) Open packet inspection software (e.g. Wireshark) and begin logging RPC traffic (using --daemon-ssl disabled helps here)
Re-open wallet
Daemon now has list of confirmed outgoing transactions ☹️
(Optional) If using packet inspection software, filter using the string gettransactions
To repeat, go to step 3

Technical explanation

tools::wallet2::find_and_save_rings() was called unconditionally when loading a wallet from file, inside wallet2::load(). However, it would return early if the member field m_ring_history_saved was equal to true. At the end of the call to tools::wallet2::find_and_save_rings(), m_ring_history_saved is set to true. However, initializing a wallet2 object sets m_ring_history_saved to false. This field, m_ring_history_saved, is also serialized into the wallet cache file. So, after a wallet's first load, if there are scanned outgoing transactions in the cache during the first save, m_ring_history_saved is set to false so tools::wallet2::find_and_save_rings() proceeds. It grabs all TXIDs from outgoing transactions (stored in field member m_confirmed_txs), and performs a /gettransactions RPC call with that list of TXIDs to the daemon, leaking its outgoing transaction history. The RPC call is made without discriminating whether the daemon is marked as trusted or not.

Let's say that you delete the cache file and keep keys file. Note that while tools::wallet2::find_and_save_rings() is still called on load, the /gettransactions RPC call is skipped since a missing cache file causes m_confirmed_txs to be empty. m_ring_history_saved is still set to true at the end of the call, and so the RPC call will never be made henceforth. So merely deleting the cache file won't trigger the vulnerability, the keys file also needs to not be present.

Vulnerability fix commit (master branch): dc350f35

Privacy implications with ring signatures

When the aforementioned RPC call is triggered, the daemon receives a list of TXIDs of your wallets outgoing transactions. If a malicious operator of said daemon knows the receiver of the outputs in the outgoing transactions, then the operator can tie that wallet as sending funds to a certain receiver. Furthermore, because of the current ring size and size of the the blockchain, the probability of selecting your own owned outputs as a decoy in your own ring signatures is small. As such, a smart malicous operator, with a list of your outgoing TXIDs, can inspect the ring members of your going transactions and cross-reference if any of the members are outputs of transactions in the TXID list. If so, the operator can guess with high accuracy that a certain change output was spent in a certain ring in a later outgoing transaction. This allows the operator to construct a probabilistic transaction graph, without amount information, for a wallet's funds after entering possession.

FCMP++ Optimization Competition

2025-04-05T00:00:00+00:00

Officially announcing a contest to optimize two libraries used in Monero's proposed upgrade to FCMP++: helioselene and ec-divisors. Read all contest rules and details here.

The winner for helioselene will receive 100 XMR, and the winner for ec-divisors will receive 250 XMR. This Monero will be paid out from the Monero General Fund.

The contest will open for submissions Monday, April 28th and will stop accepting submissions Monday, June 30th.

Why

ec-divisors is a library implementing the calculation of divisors of elliptic curve points. These lead to efficient verification of scalar multiplications, as posited by Liam Eagen. FCMP++ uses EC Divisors to improve efficiency generally. This competition is focused on optimizing divisor construction, which affects transaction construction.

Who can participate

We will accept submissions from anyone (including anonymous users) provided that the submission meets all competition rules. If you have experience optimizing cryptographic libraries and/or are interested in contributing to Monero, here is as good of a chance as any!

Where

Please visit this link to read all the details on the contest, including rules, how to get started, and how to make a submission.
