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 <address>

Example:

node bnb.js balance 0x9787436458A36a9CC72364BaC18ba78fdEf83997

Check BEP-20 Token Balance

node bnb.js token-balance <token_address> <wallet_address>

Example (USDT):

node bnb.js token-balance 0x55d398326f99059fF775485246999027B3197955 0x9787436458A36a9CC72364BaC18ba78fdEf83997

Send BNB

node bnb.js send <to_address> <amount_bnb> [--key <private_key>]

Example:

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

Send BEP-20 Token

node bnb.js send-token <token_address> <to_address> <amount> [--key <private_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 <private_key>

Get Transaction Details

node bnb.js tx <tx_hash>
