# BNB Chain Skill Basic operations on BNB Chain (BSC). Check balances and send transactions. ## Setup Requires Node.js and ethers.js: ```bash cd ~/.openclaw/workspace/skills/bnb-chain && npm install ethers --silent ``` ## Configuration Store your private key securely. The skill reads from environment variable: ```bash 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 ```bash node bnb.js balance <address> ``` Example: ```bash node bnb.js balance 0x9787436458A36a9CC72364BaC18ba78fdEf83997 ``` ### Check BEP-20 Token Balance ```bash node bnb.js token-balance <token_address> <wallet_address> ``` Example (USDT): ```bash node bnb.js token-balance 0x55d398326f99059fF775485246999027B3197955 0x9787436458A36a9CC72364BaC18ba78fdEf83997 ``` ### Send BNB ```bash node bnb.js send <to_address> <amount_bnb> [--key <private_key>] ``` Example: ```bash node bnb.js send 0xRecipient 0.01 --key 0xYourPrivateKey ``` ### Send BEP-20 Token ```bash node bnb.js send-token <token_address> <to_address> <amount> [--key <private_key>] ``` Example (send 10 USDT): ```bash node bnb.js send-token 0x55d398326f99059fF775485246999027B3197955 0xRecipient 10 --key 0xYourPrivateKey ``` ### Get Wallet Address from Private Key ```bash node bnb.js address <private_key> ``` ### Get Transaction Details ```bash node bnb.js tx <tx_hash> ``` ## Common Token Addresses (BSC Mainnet) | Token | Address | |-------|---------| | USDT | `0x55d398326f99059fF775485246999027B3197955` | | USDC | `0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d` | | BUSD | `0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56` | | WBNB | `0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c` | ## RPC Endpoints Default: `https://bsc-dataseed.binance.org/` Alternatives: - `https://bsc-dataseed1.binance.org/` - `https://bsc-dataseed2.binance.org/` - `https://bsc-dataseed3.binance.org/` - `https://bsc-dataseed4.binance.org/` ## 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
