BEP20 token must implement the interface IBEP20 in IBEP20.sol. This is a template contract BEP20Token.template. Users just need to fill in _name, _symbol, _decimals and _totalSupply according to their own requirements:
Object - The transaction object to send:
from - String|Number: The address for the sending account. Uses the web3.eth.defaultAccount property, if not specified. Or an address or index of a local wallet in web3.eth.accounts.wallet.
to - String: (optional) The destination address of the message, left undefined for a contract-creation transaction.
value - Number|String|BN|BigNumber: (optional) The value transferred for the transaction in wei, also the endowment if it’s a contract-creation transaction.
gas - Number: (optional, default: To-Be-Determined) The amount of gas to use for the transaction (unused gas is refunded).
gasPrice - Number|String|BN|BigNumber: (optional) The price of gas for this transaction in wei, defaults to web3.eth.gasPrice.
data - String: (optional) Either a ABI byte string containing the data of the function call on a contract, or in the case of a contract-creation transaction the initialisation code.
nonce - Number: (optional) Integer of a nonce. This allows to overwrite your own pending transactions that use the same nonce.
// // Make a transaction using the promise
web3.eth.sendTransaction({
from: holder,
to: '0x0B75fbeB0BC7CC0e9F9880f78a245046eCBDBB0D',
value: '1000000000000000000',
gas: 5000000,
gasPrice: 18e9,
}, function(err, transactionHash) {
if (err) {
console.log(err);
} else {
console.log(transactionHash);
}
});

BEP20 token must implement the interface IBEP20 in IBEP20.sol. This is a template contract BEP20Token.template. Users just need to fill in _name, _symbol, _decimals and _totalSupply according to their own requirements:
constructor() public { _name = {{TOKEN_NAME}}; _symbol = {{TOKEN_SYMBOL}}; _decimals = {{DECIMALS}}; _totalSupply = {{TOTAL_SUPPLY}}; _balances[msg.sender] = _totalSupply;
} Then users can use Remix IDE and Metamask to compile and deploy the BEP20 contract to BSC.
