Monero (XMR) released version 0.18.5.4 on October 16, 2026, a maintenance update that fixes DNSSEC validation and JSON request handling, according to Monero. The Monero price is 644.86 USD as of October 23, 2026, up 11.23 percent compared with the UTC daily close of October 22, 2026.

Version 0.18.5.4 targets two software paths

The official release describes version 0.18.5.4 as a minor release containing bug fixes. Its daemon, the background program that maintains a synchronized copy of the blockchain, fixes DNSSEC validation for checkpoints, blocklists and update checks. DNSSEC is a system for verifying that domain-name responses came from the correct source and were not altered in transit.

The update also restores string-to-integer conversion in JSON requests sent through Monero's remote procedure call interface, according to Monero. The release notes state that this behavior is scheduled for removal in version 0.19, making the interface change relevant to applications that communicate with Monero nodes.

FCMP++ stressnet reached block 3,102,800

A separate development milestone involved the FCMP++ and Carrot stressnet, an experimental network used to test protocol changes under load. The network forked at block 3,102,800 on October 5, 2026, according to CryptoTicker.

FCMP++ stands for Full-Chain Membership Proofs, a proposed privacy technology designed to expand the set of possible transaction inputs covered by a proof. CryptoTicker reported that the October 5 event involved the test network rather than Monero's production network. The report also described hot-cold wallet testing, Transaction Relay v2 improvements and RandomX v2 support as part of the experimental software.
