About BNB (BNB)

Layer-1 blockchain

BNB (BNB) is a Layer-1 blockchain — a base network with its own consensus, validators, and native coin (BNB) used to pay fees and secure the chain. Developers build applications directly on it, and BNB is the asset that powers the whole ecosystem.

How does BNB work?

The BNB network is maintained by a distributed set of participants who validate transactions and add them to the blockchain. BNB is required to pay for transactions and, on many networks, to stake and help secure the chain in exchange for rewards.

What is BNB used for?

BNB pays network fees, can often be staked for yield, and serves as the core unit of value across apps built on BNB. Demand for BNB tends to track activity and adoption on the network itself.

How a BNB swap works

Enter the amount you want to exchange, pick the asset on the other side, and SwapRocket queries every connected exchange partner at once. You choose an offer, paste the wallet address that should receive the funds, and send BNB to the deposit address shown. The partner executes the trade and pays out to your address — SwapRocket never holds your coins, and there is no account to create before you start.

Choosing a rate for BNB

Three offers are presented for every BNB exchange. The best rate returns the largest amount for the size you entered. The fastest route favours the partner with the shortest expected settlement time, which matters when the market is moving. The fixed rate locks the quoted amount for the duration of the order, so what you are shown is what arrives, at the cost of a slightly smaller payout. Floating offers can move with the market between deposit and settlement.

Networks and addresses for BNB

BNB settles on BSC. Always send from and to an address on that network: a deposit sent over a different chain cannot be recovered by the exchange partner. When an asset exists on several chains, pick the matching network in the widget before copying the deposit address, and send a small test amount first if you are unsure.

How does a token that started as an exchange fee discount end up securing an entire blockchain's validator set?

BNB began life on Ethereum as a simple utility token, one whose only documented job was to make trading fees cheaper on a single exchange. Today the same ticker denominates gas on BNB Smart Chain, backs a validator staking system, and is reduced in supply on a fixed schedule. Tracing how BNB moved from a discount coupon to a network's base asset explains why its supply mechanics and its role in consensus are now inseparable.

A fee token that outgrew its original chain

BNB launched in 2017 as an ERC-20 token on Ethereum, created to give traders a discount on fees at the Binance exchange in its early years. That original purpose — a usable, tradable rebate — meant the token needed no consensus role of its own; it just had to exist as a balance someone could spend. The whitepaper history preserved by BNB Chain still documents that starting point, including the original supply figures and the discount mechanics that gave the token its first use.

The project later moved its primary chain away from Ethereum, first to an independent Binance Chain and then to what is now called BNB Smart Chain, an EVM-compatible network. BNB itself migrated across these chains, from an ERC-20 balance to the native gas asset of the new network. A native asset has to do more than sit in a wallet: it has to pay for every transaction and, on BNB Smart Chain, back the accounts that produce blocks.^{[1], [2]}

Proof of Staked Authority: fewer validators, faster blocks

BNB Smart Chain's consensus, Parlia, combines proof-of-stake elections with a rotating, limited set of active validators, an approach the chain calls Proof of Staked Authority. Instead of every staked account being eligible to propose a block at any moment, a bounded validator set — currently drawn from accounts with the largest delegated stake — takes turns producing blocks in a fixed order, which keeps block times short and predictable.

Validators are chosen through staking rather than appointment: BNB holders delegate their tokens to a validator candidate, and the candidates with the most delegated stake enter the active set for each epoch. This ties block production directly to how much BNB the network's own token holders are willing to commit, rather than to a fixed, permanently fixed list of operators.^{[3], [4]}

A supply that is designed to shrink

BNB's issuance runs in the opposite direction from an inflationary gas token: a portion of BNB is periodically removed from circulation through burns, following mechanics published by the chain's maintainers, including a real-time auto-burn formula that adjusts the amount burned to on-chain price and block production data rather than a fixed number set once and left alone.

Because the burns are executed by protocol-level or published smart-contract logic rather than manual transfers to a wallet, anyone can verify the reduction in circulating supply against the chain's own records. This is a deliberate design decision distinct from a fee-burning mechanism that funds a treasury: the tokens are permanently removed from what can ever be staked, spent or traded.^[5]

One asset, two ledgers, one gas market

BNB Smart Chain kept close compatibility with the Ethereum Virtual Machine, so contracts and tooling built for Ethereum generally work with minimal changes. BNB fills the same functional role that ETH fills there: it is the unit gas fees are paid in, and every state-changing transaction consumes some of it regardless of which token is being moved or traded.

That dual role — governance-adjacent staking asset and everyday gas token — means BNB's price and availability affect the practical cost of using applications on the chain, not just its market value. A period of network congestion raises the BNB cost of a transaction the same way rising demand for Ethereum block space raises the ETH cost of a transaction there.^{[2], [3]}

The trade-off in a bounded validator set

Limiting active block producers to a defined set, chosen by delegated stake, is what gives BNB Smart Chain its short block times and low fees relative to less bounded designs. The documented trade-off is that a smaller active set concentrates block production among fewer independent operators than a design with no cap on participants, and the size of that set is itself a governance parameter that can change between chain upgrades.

This is not a hidden flaw; the chain's own documentation describes the validator election mechanics and the current set size openly, and delegated staking gives BNB holders a direct, on-chain lever to shift which validators hold that role. It is the same efficiency-versus-participant-count trade-off every bounded-validator design has to make explicit.^{[3], [4]}

What this means when you swap BNB

BNB exists on more than one network under the same ticker: as the native asset of BNB Smart Chain, and in wrapped or bridged forms elsewhere. Confirm which network a deposit address is for before sending — a BNB Smart Chain address and an address on another chain are not interchangeable, even when a wallet displays the same symbol.

Because BNB is also the gas token on BNB Smart Chain, a swap that lands you a BNB balance there also gives you what you need to pay fees for a subsequent transaction, which is not automatically true when receiving other assets on that chain. Check the quoted network fee and confirm the deposit is native BNB Smart Chain BNB rather than a bridged representation before relying on it to cover onward gas costs.
