Broadcast signed transaction to BSC blockchain. This method is used internally from Tatum KMS or Tatum client libraries. It is possible to create custom signing mechanism and use this method only for broadcasting data to the blockchain.

`bscGenerateAddress()`

Example

#️⃣ Execute command in terminal

✨ php -f bscGenerateAddress.php

Return type

\Tatum\Model\GeneratedAddressBsc

Description

Generate BSC account address from Extended public key

1 credit per API call

Generate BSC account deposit address from Extended public key. Deposit address is generated for the specific index - each extended public key can generate up to 2^31 addresses starting from index 0 until 2^31.

`bscGenerateAddressPrivateKey()`

Example

#️⃣ Execute command in terminal

✨ php -f bscGenerateAddressPrivateKey.php

Request

POST /v3/bsc/wallet/priv

$priv_key_request	\Tatum\Model\PrivKeyRequest

Return type

\Tatum\Model\PrivKey

Description

Generate BSC private key

1 credit per API call

Generate private key of address from mnemonic for given derivation path index. Private key is generated for the specific index - each mnemonic can generate up to 2^31 private keys starting from index 0 until 2^31.

`bscGenerateWallet()`

Example

#️⃣ Execute command in terminal

✨ php -f bscGenerateWallet.php

Request

GET /v3/bsc/wallet

Type signature

(new \Tatum\Sdk())->{mainnet/testnet}()->api()->bNBSmartChain()->bscGenerateWallet(
    [ string $mnemonic ]

Parameters

Name	Type	Description	Notes
$mnemonic	string	Mnemonic to use for generation of extended public and private keys.	[optional]

Return type

\Tatum\Model\Wallet

Description

Generate BSC wallet

1 credit per API call

Tatum supports BIP44 HD wallets. It is very convenient and secure, since it can generate 2^31 addresses from 1 mnemonic phrase. Mnemonic phrase consists of 24 special words in defined order and can restore access to all generated addresses and private keys. Each address is identified by 3 main values:

Private Key - your secret value, which should never be revealed
Public Key - public address to be published
Derivation index - index of generated address

Tatum follows BIP44 specification and generates for BSC wallet with derivation path m’/44’/60’/0’/0. More about BIP44 HD wallets can be found here - https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki. Generate BIP44 compatible BSC wallet.

Description

Invoke a method in a smart contract on BNB Smart Chain

2 credits per API call

Invoke a method in an existing smart contract on BNB Smart Chain.

You can call a read-only or write method.

For read-only methods, the output of the invoked method is returned.
For write methods, the ID of the associated transaction is returned.

Troubleshooting a failed transaction Tatum ensures that this API works against the blockchain (accesses the blockchain, finds the specified smart contract, and executes the specified ABI method with the provided parameters). However, because this API can be run against any smart contract on the blockchain, Tatum cannot in any way guarantee that the method itself will be executed successfully.

If you have issues with invoking the method, refer to the user documentation for this method, or contact the author of the smart contract.

For more information about invoking methods in smart contracts, see this article on our Support Portal.

Signing a transaction When invoking a method in a smart contract, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.

Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the testnet of a blockchain.

For signing transactions on the mainnet, we strongly recommend that you use the Tatum Key Management System (KMS) and provide the signature ID instead of the private key in the API. Alternatively, you can use the Tatum JavaScript client.
