Description
Basic BNB Chain operations — check balances, send BNB, send BEP-20 tokens.
README (SKILL.md)

BNB Chain Skill

Basic operations on BNB Chain (BSC). Check balances and send transactions.

Setup

Requires Node.js and ethers.js:

cd ~/.openclaw/workspace/skills/bnb-chain && npm install ethers --silent

Configuration

Store your private key securely. The skill reads from environment variable:

export BNB_PRIVATE_KEY="0x..."

Or pass it directly to the helper script.

Usage

All operations use the helper script: bnb.js

Check BNB Balance

node bnb.js balance \x3Caddress>

Example:

node bnb.js balance 0x9787436458A36a9CC72364BaC18ba78fdEf83997

Check BEP-20 Token Balance

node bnb.js token-balance \x3Ctoken_address> \x3Cwallet_address>

Example (USDT):

node bnb.js token-balance 0x55d398326f99059fF775485246999027B3197955 0x9787436458A36a9CC72364BaC18ba78fdEf83997

Send BNB

node bnb.js send \x3Cto_address> \x3Camount_bnb> [--key \x3Cprivate_key>]

Example:

node bnb.js send 0xRecipient 0.01 --key 0xYourPrivateKey

Send BEP-20 Token

node bnb.js send-token \x3Ctoken_address> \x3Cto_address> \x3Camount> [--key \x3Cprivate_key>]

Example (send 10 USDT):

node bnb.js send-token 0x55d398326f99059fF775485246999027B3197955 0xRecipient 10 --key 0xYourPrivateKey

Get Wallet Address from Private Key

node bnb.js address \x3Cprivate_key>

Get Transaction Details

node bnb.js tx \x3Ctx_hash>

Security Notes

  • Never commit private keys to git
  • Use environment variables or secure storage
  • Double-check recipient addresses before sending
  • Start with small test amounts
Usage Guidance
This skill appears to do what it claims (send/check BNB and BEP-20 tokens), but several things need attention before installing: - Inspect bnb.js source to confirm it only interacts with expected RPCs and does not exfiltrate keys. - Prefer setting BNB_PRIVATE_KEY in a secure secret store rather than passing the key on the CLI (CLI args can be stored in shell history). - Ensure package.json/package-lock.json pin the ethers version you expect; run npm install in an isolated environment (or inspect the package-lock) before trusting network installs. - Consider disabling autonomous model invocation for this skill (or require explicit user invocation) because it can perform transactions with your keys. - If you lack confidence in the code, do not provide real private keys — test with a throwaway key and small amounts first. These inconsistencies (undeclared env var and implicit installs) make the skill suspicious rather than clearly benign.
Capability Analysis
Type: OpenClaw Skill Name: bnb-chain Version: 0.1.0 The skill is designed for basic BNB Chain operations, including checking balances and sending transactions. It uses the legitimate `ethers.js` library and handles private keys as expected for a cryptocurrency interaction tool, either via environment variables (`BNB_PRIVATE_KEY`) or command-line arguments. The `SKILL.md` provides clear instructions and includes security notes advising against committing private keys. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, prompt injection attempts against the agent, or obfuscation. All actions are directly aligned with the stated purpose of interacting with the BNB Chain.
Capability Assessment
⚠ Purpose & Capability
Name/description (check/send BNB and BEP-20 tokens) aligns with the included bnb.js and instructions, but registry metadata does not declare the required Node binary or the BNB_PRIVATE_KEY env var that the SKILL.md explicitly requires — an inconsistency in declared requirements.
⚠ Instruction Scope
SKILL.md instructs running bnb.js to read a private key from the BNB_PRIVATE_KEY environment variable or accept a private key on the CLI and to npm install ethers in the local skill workspace. Reading a private key is expected for this purpose, but passing keys on the CLI (shell history exposure) and performing ad-hoc installs at runtime expand the operational scope and risk.
ℹ Install Mechanism
There is no formal install spec in the registry, but SKILL.md tells the user to run npm install ethers in the skill workspace. That implicit install (network fetch of a package) is normal for a Node helper but should be declared; package.json and package-lock.json are present but the registry did not publish an install step.
⚠ Credentials
The skill requires a private key (BNB_PRIVATE_KEY) to function but the registry metadata lists no required environment variables or primary credential. Asking for raw private keys (and allowing them on the CLI) is sensitive and the required secret should be explicitly declared and justified.
⚠ Persistence & Privilege
The skill is not marked always:true, but disable-model-invocation is not set, so the model could invoke this skill autonomously. Because it can use private keys to send transactions, allowing autonomous invocation without explicit user gating is risky.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install bnb-chain
  3. After installation, invoke the skill by name or use /bnb-chain
  4. Provide required inputs per the skill's parameter spec and get structured output
