# Shared Chain Name Support

> This file is shared across all onchainos skills.

The CLI accepts human-readable chain names and resolves them automatically.

The following 6 chains support **wallet address creation** (i.e., you can generate a wallet address on these chains):

| Chain | Name | chainIndex |
|---|---|---|
| XLayer | `xlayer` | `196` |
| Solana | `solana` | `501` |
| Ethereum | `ethereum` | `1` |
| Base | `base` | `8453` |
| BSC | `bsc` | `56` |
| Arbitrum | `arbitrum` | `42161` |

> **Note**: The wallet supports interacting with 17+ chains beyond this list (e.g., Polygon, Avalanche, Optimism).
> Run `onchainos wallet chains` for the full list of supported chains.


# Shared Pre-flight Checks

> This file is shared across all onchainos skills. Follow these steps before the first `onchainos` command each session.

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.

1. **Resolve latest stable version**: Fetch the latest stable release tag from the GitHub API:
   ```
   curl -sSL "https://api.github.com/repos/okx/onchainos-skills/releases/latest"
   ```
   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
   https://github.com/okx/onchainos-skills.

2. **Install or update**: If `onchainos` is not found, or if the cache at `~/.onchainos/last_check` (`$env:USERPROFILE\.onchainos\last_check` on Windows) is older than 12 hours:
   - Download the installer and its checksum file from the latest release tag:
     - **macOS/Linux**:
       `curl -sSL "https://raw.githubusercontent.com/okx/onchainos-skills/${LATEST_TAG}/install.sh" -o /tmp/onchainos-install.sh`
       `curl -sSL "https://github.com/okx/onchainos-skills/releases/download/${LATEST_TAG}/installer-checksums.txt" -o /tmp/installer-checksums.txt`
     - **Windows**:
       `Invoke-WebRequest -Uri "https://raw.githubusercontent.com/okx/onchainos-skills/${LATEST_TAG}/install.ps1" -OutFile "$env:TEMP\onchainos-install.ps1"`
       `Invoke-WebRequest -Uri "https://github.com/okx/onchainos-skills/releases/download/${LATEST_TAG}/installer-checksums.txt" -OutFile "$env:TEMP\installer-checksums.txt"`
   - Verify the installer's SHA256 against `installer-checksums.txt`. On mismatch, **stop** and warn — the installer may have been tampered with.
   - Execute: `sh /tmp/onchainos-install.sh` (or `& "$env:TEMP\onchainos-install.ps1"` on Windows).
     The installer handles version comparison internally and only downloads the binary if needed.
   - On other failures, point to https://github.com/okx/onchainos-skills.

3. **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`). Construct the installed tag as `v<version>`.
   Download `checksums.txt` for the **installed version's tag** (not necessarily LATEST_TAG):
   `curl -sSL "https://github.com/okx/onchainos-skills/releases/download/v<version>/checksums.txt" -o /tmp/onchainos-checksums.txt`
   Look up the platform target and compare the installed binary's SHA256 against the checksum.
   On mismatch, reinstall (step 2) and re-verify. If still mismatched, **stop** and warn.
   - Platform targets — macOS: `arm64`->`aarch64-apple-darwin`, `x86_64`->`x86_64-apple-darwin`; Linux: `x86_64`->`x86_64-unknown-linux-gnu`, `aarch64`->`aarch64-unknown-linux-gnu`, `i686`->`i686-unknown-linux-gnu`, `armv7l`->`armv7-unknown-linux-gnueabihf`; Windows: `AMD64`->`x86_64-pc-windows-msvc`, `x86`->`i686-pc-windows-msvc`, `ARM64`->`aarch64-pc-windows-msvc`
