Keep BNB in your wallet to pay gas.
Failed transactions still consume gas.
A finalized transaction cannot be reversed.

Short answer

BNB Chain processes a transaction in stages: your wallet signs and broadcasts it, a validator includes it in a block, and the network finalizes that block.

This guide follows a transaction from send to confirmation. You need a wallet you control, BNB for the fee, and the right network. BNB Chain is not the Binance exchange.

What do I need before sending?

Gas pays validators to include your transaction, and BNB Chain charges that gas in BNB. BNB is the network's native token. Before sending, you need a wallet you control, BNB for the fee, the right network, and the recipient's full address.

Before you send

A wallet where you control the private keys or seed phrase.
BNB in that wallet to cover gas.
The recipient's full address.
The network selected in your wallet matches the address.

How does BNB Chain process a transaction?

Your wallet estimates the gas and shows the fee before you sign. You pay gas in BNB, and a failed transaction still consumes gas. BNB Chain says it uses fast finality and slashing penalties to secure the network.

1Review the gas estimateCheck the fee and total cost before you approve.
2Sign and broadcastYour wallet signs the transaction with your private key and sends it to nodes, which pass it to validators.
3Wait for inclusionBNB Chain picks validators by the BNB staked or delegated to them, and one includes your transaction in a block.
4Wait for finalityWhen validators finalize the block, BNB Chain treats the transaction as confirmed.
5Check the statusCopy the transaction hash into a block explorer to see pending, confirmed, or failed.

Which BNB Chain network am I using?

BNB Chain is an umbrella name for more than one network, and each network processes transactions on its own. The network your wallet connects to decides where your transaction goes.

BNB Smart Chain has run since 2020.
opBNB is a separate layer 2 network that launched in 2023.
BNB Beacon Chain handled staking and governance and was retired in 2024.
The network in your wallet must match the address you send to.

What should I do after sending?

Copy the transaction hash into a block explorer to see whether it is pending, confirmed, or failed. A wrong network or a fee set too low can leave a transaction stuck or dropped. A wrong address usually results in a successful transfer to an unintended recipient.

Frequently asked questions

BNB Smart Chain runs tokens and apps built for Ethereum. BNB Beacon Chain handled staking and governance and was retired in 2024.

Yes. Gas on BNB Chain is paid in BNB, so a wallet without BNB cannot broadcast a transaction.

BNB Chain says it produces blocks at short intervals and uses fast finality, so a typical transfer confirms in seconds.

No. Once validators finalize the block, the record stands. Reversing the effect takes a new transaction from whoever controls the receiving address.
