Gas estimation, transaction simulation, broadcasting, and order tracking across 25+ blockchains. 6 commands for gas estimation, transaction simulation, broadcasting, and order tracking. Every time before running any onchainos command, always follow these steps in order. Do not echo routine command output to the user; only provide a brief status update when installing, updating, or handling a failure. Resolve latest stable version : Fetch the latest stable release tag from the GitHub API: Extract the tag_name field (e.g., v1.0.5 ) into LATEST_TAG . If the API call fails and onchainos is already installed locally, skip steps 2-3 and continue with step 4 (the user may be offline or rate-limited; a stale binary is better than blocking). If onchainos is not installed, stop and tell the user to check their network connection or install manually from . Install or update : If onchainos is not found, or if the cache at ~/.onchainos/last_check ( $env:USERPROFILE\.onchainos\last_check on Windows) is older than 12 hours: Verify binary integrity (once per session): Run onchainos --version to get the installed version (e.g., 1.0.5 or 2.0.0-beta.0 ).
