On the official site of Crash (CrashMetaX / @CrashMetaX), this note covers Keystone 3.
Keystone 3 firmware 3.1.4 arrived on October 16, 2026 and made clear improvements to how the device reads SOL transactions in the Web3 edition.
Release Notes Origin
The update came directly from the official GitHub repository maintained by Keystone. Release notes listed exact changes for transaction handling and wallet setup. Separate builds shipped for each edition. Users accessed the files through the official firmware site at keyst.one/firmware.
Transaction Parsing Upgrade
The firmware improved how the Web3 edition parsed SOL transactions. This change addressed reading steps for Solana based activity on the device. The notes from the repository spelled out the parsing refinement without additional claims. The same repository confirmed the Solana capable hardware wallet firmware carried this update on the stated date.
Setup Steps for Two Editions
Wallet setup steps received improvements in both the Web3 edition and the BTC Only edition. The release notes grouped these changes together for the two builds. Each edition kept its own dedicated build so the setup adjustments applied where intended. The notes presented the setup work as a direct response to user flow in those versions.
Build Delivery Method
Keystone delivered the firmware as separate builds for each edition. The Web3 edition and BTC Only edition each received their matching update package. This approach kept the changes edition specific. The release page on GitHub showed the builds listed side by side for download.
Checksum Verification
Each build included a published checksum. Users could compare the value on the device after download. The release page supplied the checksums alongside the files. This step allowed direct confirmation before installation.
Access Point for Users
The firmware reached users through the official firmware site. The page at keyst.one/firmware hosted the files for the October 16, 2026 release. The GitHub tag linked back to the same files and notes. This route gave a single source for the complete package.
What the Notes Covered
The repository notes focused on the parsing improvement for SOL transactions in the Web3 edition. They also covered the shared setup changes across the Web3 and BTC Only editions. No other transaction types or editions appeared in the listed updates. The notes stayed limited to those two areas.
Edition Specific Builds
The update shipped with distinct files for the Web3 edition and the BTC Only edition. This separation ensured the setup changes landed correctly on each device type. The release page displayed the builds clearly so users selected the matching file. The structure kept the Solana parsing change inside the Web3 build only.
Practical Steps After Release
Users downloaded the firmware from the official site after the October 16, 2026 posting. They compared the published checksum on the device before proceeding. The separate builds allowed targeted installation without cross edition files. The GitHub notes served as the reference for what changed in each case.
