BNB Beacon Chain

BNB Beacon Chain is a blockchain developed by Binance. With Tatum, you can access the most commonly used BNB Beacon Chain methods. These methods bring a certain level of abstraction and are used for applications that communicate with the blockchain directly.

BNB Beacon Chain does not provide the smart contract functionality.

Tatum supports the following BNB Beacon Chain networks:

Mainnet, the primary public production blockchain
Testnet, a chain used for testing purposes. The testnet cryptocurrency has no value, and you can obtain it from a faucet (for example, get it from the BNB Smart Chain Faucet and transfer it to your BNB Beacon Chain address using the Binance Wallet).

Generate Binance wallet

5 credits per API call.

Generate BNB account. Tatum does not support HD wallet for BNB, only specific address and private key can be generated.

Send Binance / Binance Token from account to account

10 credits per API call.

Send Binance or Binance Token token from account to account.

This operation needs the private key of the blockchain address. Every time the funds are transferred, the transaction must be signed with the corresponding private key. No one should ever send it's own private keys to the internet because there is a strong possibility of stealing keys and loss of funds. In this method, it is possible to enter privateKey. PrivateKey should be used only for quick development on testnet versions of blockchain when there is no risk of losing funds. In production, Tatum KMS should be used for the highest security standards, and signatureId should be present in the request. Alternatively, using the Tatum client library for supported languages.
