Onchain OS Security

5 commands for token risk analysis, DApp phishing detection, transaction pre-execution security, signature safety, and approval management.

Pre-flight Checks

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 proceed to run the command (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
    • Hash command — macOS/Linux: shasum -a 256 ~/.local/bin/onchainos; Windows: (Get-FileHash "$env:USERPROFILE\.local\bin\onchainos.exe" -Algorithm SHA256).Hash.ToLower()
  4. Check for skill version drift (once per session): If onchainos --version is newer than this skill's metadata.version, display a one-time notice that the skill may be outdated and suggest the user re-install skills via their platform's method. Do not block.

  5. Do NOT auto-reinstall on command failures. Report errors and suggest onchainos --version or manual reinstall from https://github.com/okx/onchainos-skills.

  6. Rate limit errors. If a command hits rate limits, the shared API key may be throttled. Suggest creating a personal key at the OKX Developer Portal. If the user creates a .env file, remind them to add .env to .gitignore.

Fail-safe Principle (CRITICAL)

If any security scan command fails for ANY reason (network error, API error, timeout, rate limiting, malformed response), the Agent MUST:

  • NOT proceed with the associated transaction, swap, approval, or signature.
  • Report the error clearly to the user.
  • Suggest retrying the scan before continuing.

A security scan that fails to complete is NOT a "pass". Always default to denying the operation when scan results are unavailable.

Risk Action Priority Rule

block > warn > safe (empty). The top-level action field reflects the highest priority from riskItemDetail.

action value Risk Level Agent Behavior
(empty/null) Low risk Safe to proceed
warn Medium risk Show risk details, ask for explicit user confirmation
block High risk Do NOT proceed, show risk details, recommend cancel
  • Risk scan result is still valid even if simulation fails (simulator.revertReason may contain the revert reason).
  • If warnings field is populated, the scan completed but some data may be incomplete. Still present available risk information.
  • An empty/null action in a successful API response means "no risk detected". But if the API call failed, the absence of action does NOT mean safe — apply the fail-safe principle.

Security commands do not require wallet login. They work with any address.

Chain Name Support

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

Chain Name chainIndex
XLayer xlayer 196
Ethereum ethereum or eth 1
Solana solana or sol 501
BSC bsc or bnb 56
Polygon polygon or matic 137
Arbitrum arbitrum or arb 42161
Base base 8453
Avalanche avalanche or avax 43114
Optimism optimism or op 10
zkSync Era zksync 324
Linea linea 59144
Scroll scroll 534352

Address format note: EVM addresses (0x...) work across Ethereum/BSC/Polygon/Arbitrum/Base etc. Solana addresses (Base58) and Bitcoin addresses (UTXO) have different formats. Do NOT mix formats across chain types.

Command Index

# Command Description
1 onchainos security token-scan Token risk / honeypot detection (all chains)
2 onchainos security dapp-scan DApp / URL phishing detection (chain-agnostic)
3 onchainos security tx-scan Transaction pre-execution security (EVM + Solana)
4 onchainos security sig-scan Message signature security (EVM only)
5 onchainos security approvals Token approval / Permit2 authorization query (EVM only)

Reference Loading Rules (MANDATORY)

Before executing ANY security command, you MUST read the corresponding reference document from skills/okx-security/references/. Do NOT rely on prior knowledge — always load the reference first.

User intent Read this file FIRST
Token safety, honeypot, is this token safe, 代币安全, 蜜罐检测, 貔貅盘 references/risk-token-detection.md
DApp/URL phishing, is this site safe, 钓鱼网站 references/risk-domain-detection.md
Transaction safety, tx pre-execution, signature safety, approve safety, 交易安全, 签名安全 references/risk-transaction-detection.md
Approvals, allowance, Permit2, revoke, 授权管理, 授权查询, 风险授权 references/risk-approval-monitoring.md

When a workflow involves multiple commands (e.g., token-scan then tx-scan), load each reference before executing that command.

Integration with Other Skills

Security scanning is often a prerequisite for other wallet operations:

  • Before wallet send with a contract token: run token-scan to verify token safety
  • Before wallet contract-call with approve calldata: run tx-scan to check spender
  • Before interacting with any DApp URL: run dapp-scan
  • Before signing any EIP-712 message: run sig-scan

Use okx-agentic-wallet skill for the subsequent send/contract-call operations.

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/okx-security

Reload or restart Cursor to activate okx-security. Access the skill through slash commands (e.g., /okx-security) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
