Nansen Binance Publisher

Automatically fetch multi-dimensional on-chain data using Nansen CLI, compile a comprehensive and beautifully formatted daily report, and publish it to Binan...

Security Scan

The skill's declared behavior (fetch Nansen data and post to Binance Square) is plausible, but there are inconsistencies in the metadata, prompt‑injection signals in the instructions, and features (silent auto‑posting / cron guidance and advice to source key files) that increase risk and deserve caution before installing.

Purpose & Capability

The core capabilities (use nansen-cli and post to Binance Square) match the skill name and description. However, registry metadata claims no required env vars or binaries while SKILL.md explicitly lists NANSEN_API_KEY, X_SQUARE_OPENAPI_KEY and a dependency nansen-cli (npm) — an internal inconsistency that should be clarified before trusting the skill.

Instruction Scope

SKILL.md instructs the agent to run shell commands (nansen CLI), browse user‑provided URLs, and perform HTTP POSTs to Binance Square. It also describes a silent `/nansen_auto` mode and gives explicit cron examples that instruct loading keys from a local file. The instructions forbid fabricating data and demand real CLI output, but they also push scheduling and loading keys from files (source ~/.my_secure_keys) which could encourage storing credentials in files and enable automatic posting without a clear safety boundary.

Install Mechanism

There is no install spec in the bundle (instruction‑only), so nothing is automatically written to disk by the skill itself. The SKILL.md instructs the agent to prompt the user before running `npm install -g nansen-cli` — this is a moderate‑risk install but proportionate to the stated purpose if the user explicitly approves. No apparent use of untrusted download URLs or archives in the provided materials.

Credentials

The SKILL.md legitimately requires two keys (NANSEN_API_KEY and X_SQUARE_OPENAPI_KEY) which align with its stated purpose. The problem: the registry metadata claims 'none' for required env vars — that mismatch is suspicious. The skill also recommends sourcing keys from a local file for cron jobs, which could lead users to store secrets in plaintext if done poorly. Affiliate registration links are present (benign monetization but worth noting).

Persistence & Privilege

The skill is not marked always:true (good). However, it explicitly documents a silent `/nansen_auto` mode and provides cron examples for fully automated posting. Combined with the agent's normal ability to invoke skills autonomously, this creates a higher blast radius if the user enables silent mode or schedules cron jobs — particularly because postings act on the user's Binance account. The skill's instructions around automation should be reviewed and the user should ensure confirmation controls are enforced.

Scan Findings in Context

[unicode-control-chars] unexpected: The static pre-scan detected unicode control characters in SKILL.md. These can be used in prompt injection to manipulate parsing/interpretation. This is not expected for a simple CLI-to-API publisher and should be investigated (could be an authoring artifact or an attempt to influence evaluators/agents).

What to consider before installing

Before installing: 1) Clarify the metadata mismatch — ask the publisher why registry metadata shows no env vars while SKILL.md requires NANSEN_API_KEY and X_SQUARE_OPENAPI_KEY. 2) Do not enable /nansen_auto or set up cron jobs until you understand and test a manual flow; verify the agent always prompts for confirmation before posting. 3) Prefer storing API keys in a secure secret manager or platform-provided secret storage rather than plaintext files (avoid source ~/.my_secure_keys unless that file is securely protected). 4) Confirm that the platform will not allow the skill to run npm installs or terminal commands without an explicit, auditable consent prompt. 5) The unicode-control-chars finding is suspicious — ask the author to provide a cleaned SKILL.md and consider running the skill in a sandbox or staging environment first. If you rely on this skill for automated posting, perform a careful end‑to‑end test with a non‑critical Binance account and review all posts before enabling automation.

Nansen to Binance Square Daily Publisher

Overview

This skill instructs the Agent to act as a professional crypto data analyst and social media manager. It uses nansen-cli to fetch multi-dimensional blockchain data (Smart Money movements, Token flows, etc.), synthesizes the data into a highly structured, beautifully formatted Daily Report, and publishes it directly to Binance Square via HTTP POST.

Supported Slash Commands

To make it extremely easy for users (especially on Telegram or chat interfaces) to trigger this skill, the Agent MUST respond to the following slash commands:

• /nansen - Generates the Nansen daily report and asks for confirmation before posting.
• /nansen <URL or custom query> - Uses native web browsing to read off-chain context (e.g., a Twitter link) AND fetches Nansen on-chain data to provide a cross-validated analysis.
• /nansen <chain_name> - Generates the report for a specific chain (e.g., /nansen solana).
• /post_square - Triggers the full fetch-and-post workflow.
• /nansen_auto - Fetches data, generates the report, and posts it (Requires explicit user permission first).

Prerequisites & Authentication

This skill requires the Agent to have access to:

1. NANSEN_API_KEY: Required to fetch data.
   • If the user does not have a Nansen account or Key, the Agent MUST suggest registering via this link for a 10% discount and NXP Bonus: https://nsn.ai/7LOuQVx1Jvh
2. X_SQUARE_OPENAPI_KEY: Required to post to Binance Square.
   • If the user does not have a Binance account, the Agent MUST suggest registering via this link for fee discounts: https://accounts.binance.com/zh-CN/register?ref=35266688

Agent Behavior: The Comprehensive Daily Report Workflow

When the user asks to generate a daily report (e.g., " Nansen "), the Agent MUST execute the following steps sequentially to gather a holistic view of the market:

Step 0: Environment Auto-Setup (Explicit Consent Required)

• Check if nansen-cli is installed by running nansen --version.
• If it is not installed, the Agent MUST explicitly ask the user for permission to install it: "I need to install nansen-cli via npm to fetch data. Do you approve?"
• ONLY run npm install -g nansen-cli AFTER the user approves. NEVER install silently.

Step 1: Authentication Check

• Verify if NANSEN_API_KEY and X_SQUARE_OPENAPI_KEY are available in the environment variables.
• If missing, prompt the user to provide them gracefully, attaching the affiliate links mentioned above. DO NOT suggest saving keys in plaintext files.

Step 2: Context & On-Chain Data Fetching

The Agent must gather both off-chain context and on-chain reality to form a complete picture.

IF THE USER PROVIDES A URL OR CUSTOM TOPIC:

1. Web Context First: Use your native web browsing/search capabilities to visit the provided URL (e.g., Twitter/X link) or search the web for the project/topic. Extract the core narrative, recent news, or social sentiment.
2. On-Chain Verification: Translate the off-chain narrative into a Nansen CLI query.

NANSEN CLI EXECUTION (MANDATORY TOOL USAGE): The Agent must execute a series of Nansen CLI commands to capture macro narratives, fund flows, project analysis, and anomalies.

CRITICAL ANTI-HALLUCINATION RULE:

1. Tool Execution is Required: You MUST use your native bash, execute_command, or terminal tool to physically run the nansen CLI commands below.
2. Zero-Tolerance for Fake Data: You are FORBIDDEN from guessing, simulating, or generating placeholder data.
3. Data Verification Step: Before generating any report, you must verify that you have successfully executed the CLI tool and received REAL JSON output. If the CLI returns no data, fails, or if you cannot execute the command, report the error to the user and ABORT the report generation entirely. DO NOT proceed to Step 3 and DO NOT generate "fluff" or empty analysis.

Core Commands to Execute (via your terminal tool):

1. Macro Fund Flows (Smart Money Netflow):

   nansen research smart-money netflow --chain ethereum --limit 5 --timeframe 24h --pretty
   

2. Trending Narratives / Hot Contracts:

   nansen research profiler contract-interactions --chain ethereum --limit 5 --pretty
   

3. Smart Money Holdings & Conviction (Top Portfolio):

   nansen research portfolio holdings --address smart-money --chain ethereum --limit 5 --pretty
   

   (Note: Adjust the CLI parameters if the exact syntax for portfolio/holdings differs based on nansen schema)

Error Handling during Fetch:

• If the CLI returns UNAUTHORIZED: Stop and prompt the user to re-verify their NANSEN_API_KEY.
• If the CLI returns CREDITS_EXHAUSTED: Stop all calls immediately and inform the user to check their Nansen dashboard.
• (Note: If any command fails or returns empty, gracefully skip that section or replace it with alternative available data from Nansen CLI).

Step 3: Data Synthesis & Content Optimization (Template Selection)

The Agent must synthesize the data into a professional, highly engaging, and beautifully formatted report.

CRITICAL FORMATTING RULES:

• Adopt the tone of a Senior Crypto Researcher. Provide real insights, not just raw numbers.
• Format large numbers elegantly (e.g., $1.23M, $500K).
• NO MARKDOWN: Binance Square's API bodyTextOnly does NOT support Markdown. You MUST NOT use syntax like **bold**, *italic*, or ### headers. Use emojis and plain text spacing only to create visual hierarchy.
• ANTI-HALLUCINATION RULE: NEVER make up data. If Nansen CLI returns no data for a specific query, you MUST gracefully abort and inform the user.

DAILY RANDOM TEMPLATE SELECTION: To ensure Binance Square followers receive fresh and diverse content, the Agent MUST randomly select one of the following SIX deeply analytical templates each day. If the user asks for a specific project, default to Template 5. If the user provides a URL or custom context, ALWAYS use Template 6.

Step 4: User Confirmation

• Crucial: The Agent MUST display the fully formatted report to the user in the chat interface.
• Ask the user: ""
• Important: Ensure there are NO external links (like nansen.ai) in the final content to comply with Binance Square's posting rules.

Step 5: Publish via Binance Square API

Once the user confirms, the Agent must make the HTTP POST request to publish the content.

• Method: POST
• URL: https://www.binance.com/bapi/composite/v1/public/pgc/openApi/content/add
• Headers:
  • X-Square-OpenAPI-Key: <User's Square API Key>
  • Content-Type: application/json
  • clienttype: binanceSkill
• Body:

  {
    "bodyTextOnly": "<The exact confirmed text from Step 3>"
  }
  

Step 6: Final Feedback

• If successful (code: "000000"), construct the URL: https://www.binance.com/square/post/{id}.
• Present the final success message and the clickable link to the user.
• If errors occur (e.g., 20002 Sensitive words, 220009 Daily limit), explain the error clearly to the user and suggest fixes.

---

Security Boundary & Constraints

To ensure maximum safety and compliance:

• No File Access: The Agent MUST NOT read, write, or modify any unrelated local files or system configurations.
• No Extraneous Network Calls: The Agent is restricted to communicating ONLY with the Nansen CLI and the official Binance Square API (api.binance.com).
• Transparency: All generated content must be displayed to the user before transmission, except when explicitly invoked via the silent /nansen_auto command.

---

Automation & Scheduled Publishing (Cron Mode)

Users often want this report to run automatically (e.g., daily at 8 AM). The Agent supports scheduling via cron.

How to set up automation: If the user asks to "schedule this daily", the Agent should:

1. Provide a cron expression based on the user's requested time.
2. Instruct the user to add the command to their system's crontab. SECURITY WARNING: The Agent MUST instruct the user to use secure environment variables rather than hardcoding keys in the crontab file.

   # Secure Example: Load env vars from a secure file before running
   0 8 * * * source ~/.my_secure_keys && trae-agent run "nansen-binance-publisher" --command "/nansen_auto"
